For each listed material, the Table identifies the hazard class or specifies that the material is forbidden in transportation, and gives the proper shipping name or directs the user to the preferred proper shipping name. In addition, the Table specifies or references requirements in this subchapter pertaining to labeling, packaging, quantity limits aboard aircraft and stowage of hazardous materials aboard vessels.\n\n(b)  Column 1: Symbols.  Column 1 of the Table contains six symbols (\u201c + \u201d, \u201cA\u201d, \u201cD\u201d, \u201cG\u201d, \u201cI\u201d and \u201cW\u201d) as follows:\n\n(1) The plus (+) sign fixes the proper shipping name, hazard class and packing group for that entry without regard to whether the material meets the definition of that class, packing group or any other hazard class definition. When the plus sign is assigned to a proper shipping name in Column (1) of the \u00a7 172.101 Table, it means that the material is known to pose a risk to humans. When a plus sign is assigned to mixtures or solutions containing a material where the hazard to humans is significantly different from that of the pure material or where no hazard to humans is posed, the material may be described using an alternative shipping name that represents the hazards posed by the material. An appropriate alternate proper shipping name and hazard class may be authorized by the Associate Administrator.\n\n(2) The letter \u201cA\u201d denotes a material that is subject to the requirements of this subchapter only when offered or intended for transportation by aircraft, unless the material is a hazardous substance or a hazardous waste. A shipping description entry preceded by an \u201cA\u201d may be used to describe a material for other modes of transportation provided all applicable requirements for the entry are met.\n\n(3) The letter \u201cD\u201d identifies proper shipping names which are appropriate for describing materials for domestic transportation but may be inappropriate for international transportation under the provisions of international regulations (e.g., IMO, ICAO). An alternate proper shipping name may be selected when either domestic or international transportation is involved.\n\n(4) The letter \u201cG\u201d identifies proper shipping names for which one or more technical names of the hazardous material must be entered in parentheses, in association with the basic description. (See \u00a7 172.203(k).)\n\n(5) The letter \u201cI\u201d identifies proper shipping names which are appropriate for describing materials in international transportation. An alternate proper shipping name may be selected when only domestic transportation is involved.\n\n(6) The letter \u201cW\u201d denotes a material that is subject to the requirements of this subchapter only when offered or intended for transportation by vessel, unless the material is a hazardous substance or a hazardous waste. A shipping description entry preceded by a \u201cW\u201d may be used to describe a material for other modes of transportation provided all applicable requirements for the entry are met.\n\n(c)  Column 2: Hazardous materials descriptions and proper shipping names.  Column 2 lists the hazardous materials descriptions and proper shipping names of materials designated as hazardous materials. Modification of a proper shipping name may otherwise be required or authorized by this section. Proper shipping names are limited to those shown in Roman type (not italics).\n\n(1) Proper shipping names may be used in the singular or plural and in either capital or lower case letters. Words may be alternatively spelled in the same manner as they appear in the ICAO Technical Instructions or the IMDG Code. For example \u201caluminum\u201d may be spelled \u201caluminium\u201d and \u201csulfur\u201d may be spelled \u201csulphur\u201d. However, the word \u201cinflammable\u201d may not be used in place of the word \u201cflammable\u201d.\n\n(2) Punctuation marks and words in italics are not part of the proper shipping name, but may be used in addition to the proper shipping name. The word \u201cor\u201d in italics indicates that there is a choice of terms in the sequence that may alternately be used as the proper shipping name or as part of the proper shipping name, as appropriate. For example, for the hazardous materials description \u201cCarbon dioxide, solid or Dry ice\u201d either \u201cCarbon dioxide, solid\u201d or \u201cDry ice\u201d may be used as the proper shipping name; and for the hazardous materials description \u201cArticles, pressurized pneumatic or hydraulic,\u201d either \u201cArticles, pressurized pneumatic\u201d or \u201cArticles, pressurized hydraulic\u201d may be used as the proper shipping name.\n\n(3) The word \u201cpoison\u201d or \u201cpoisonous\u201d may be used interchangeably with the word \u201ctoxic\u201d when only domestic transportation is involved. The abbreviation \u201cn.o.i.\u201d or \u201cn.o.i.b.n.\u201d may be used interchangeably with \u201cn.o.s.\u201d.\n\n(4) Except for hazardous wastes, when qualifying words are used as part of the proper shipping name, their sequence in the package markings and shipping paper description is optional. However, the entry in the Table reflects the preferred sequence.\n\n(5) When one entry references another entry by use of the word \u201csee\u201d, if both names are in Roman type, either name may be used as the proper shipping name (e.g., Ethyl alcohol,  see  Ethanol).\n\n(6) When a proper shipping name includes a concentration range as part of the shipping description, the actual concentration, if it is within the range stated, may be used in place of the concentration range. For example, an aqueous solution of hydrogen peroxide containing 30 percent peroxide may be described as \u201cHydrogen peroxide, aqueous solution  with not less than 20 percent but not more than 40 percent hydrogen peroxide\u201d  or \u201cHydrogen peroxide, aqueous solution  with 30 percent hydrogen peroxide. \u201d Also, the percent sign (%) may be used in place of the word \u201cpercent\u201d when words in italics containing the word \u201cpercent\u201d are used in addition to the proper shipping name.\n\n(7) Use of the prefix \u201cmono\u201d is optional in any shipping name, when appropriate. Thus, Iodine monochloride may be used interchangeably with Iodine chloride. In \u201cGlycerol alpha-monochlorohydrin\u201d the term \u201cmono\u201d is considered a prefix to the term \u201cchlorohydrin\u201d and may be deleted.\n\n(8) Use of the word \u201cliquid\u201d or \u201csolid\u201d. The word \u201cliquid\u201d or \u201csolid\u201d may be added to a proper shipping name when a hazardous material specifically listed by name may, due to differing physical states, be a liquid or solid. When the packaging specified in Column 8 is inappropriate for the physical state of the material, the table provided in paragraph (i)(4) of this section should be used to determine the appropriate packaging section.\n\n(9)  Hazardous wastes.  If the word \u201cwaste\u201d is not included in the hazardous material description in Column 2 of the Table, the proper shipping name for a hazardous waste (as defined in \u00a7 171.8 of this subchapter), shall include the word \u201cWaste\u201d preceding the proper shipping name of the material. For example: Waste acetone.\n\n(10)  Mixtures and solutions.  (i) A mixture or solution meeting the definition of one or more hazard class that is not identified specifically by name, comprised of a single predominant hazardous material identified in the Table by technical name and one or more hazardous and/or non-hazardous material, must be described using the proper shipping name of the hazardous material and the qualifying word \u201cmixture\u201d or \u201csolution\u201d, as appropriate, unless\u2014\n\n(A) Except as provided in \u00a7 172.101(i)(4) the packaging specified in Column 8 is inappropriate to the physical state of the material;\n\n(B) The shipping description indicates that the proper shipping name applies only to the pure or technically pure hazardous material;\n\n(C) The hazard class, packing group, or subsidiary hazard of the mixture or solution is different from that specified for the entry;\n\n(D) There is a significant change in the measures to be taken in emergencies;\n\n(E) The material is identified by special provision in Column 7 of the \u00a7 172.101 Table as a material poisonous by inhalation; however, it no longer meets the definition of poisonous by inhalation or it falls within a different hazard zone than that specified in the special provision; or\n\n(F) The material can be appropriately described by a shipping name that describes its intended application, such as \u201cCoating solution\u201d, \u201cExtracts, flavoring\u201d or \u201cCompound, cleaning liquid.\u201d.\n\n(ii) If one or more of the conditions in paragraphs (c)(10)(i)(A) through (F) of this section is satisfied then the proper shipping name selection process in (c)(12)(ii) must be used.\n\n(iii) A mixture or solution meeting the definition of one or more hazard class that is not identified in the Table specifically by name, comprised of two or more hazardous materials in the same hazard class, must be described using an appropriate shipping description (e.g., \u201cFlammable liquid, n.o.s.\u201d). The name that most appropriately describes the material shall be used; e.g., an alcohol not listed by its technical name in the Table shall be described as \u201cAlcohol, n.o.s.\u201d rather than \u201cFlammable liquid, n.o.s.\u201d. Some mixtures may be more appropriately described according to their application, such as \u201cCoating solution\u201d or \u201cExtracts, flavoring liquid\u201d rather than by an n.o.s. entry. Under the provisions of subparts C and D of this part, the technical names of at least two components most predominately contributing to the hazards of the mixture or solution may be required in association with the proper shipping name.\n\n(11) Except for a material subject to or prohibited by \u00a7 173.21, \u00a7 173.54, \u00a7 173.56(d), \u00a7 173.56(e), \u00a7 173.224(c) or \u00a7 173.225(b) of this subchapter, a material that is considered to be a hazardous waste or a sample of a material for which the hazard class is uncertain and must be determined by testing may be assigned a tentative proper shipping name, hazard class, identification number and packing group, if applicable, based on the shipper's tentative determination according to:\n\n(i) Defining criteria in this subchapter;\n\n(ii) The hazard precedence prescribed in \u00a7 173.2a of this subchapter;\n\n(iii) The shipper's knowledge of the material;\n\n(iv) In addition to paragraphs (c)(11)(i) through (iii) of this section, for a sample of a material other than a waste, the following must be met:\n\n(A) Except when the word \u201cSample\u201d already appears in the proper shipping name, the word \u201cSample\u201d must appear as part of the proper shipping name or in association with the basic description on the shipping paper.\n\n(B) When the proper shipping description for a sample is assigned a \u201cG\u201d in Column (1) of the \u00a7 172.101 Table, and the primary constituent(s) for which the tentative classification is based are not known, the provisions requiring a technical name for the constituent(s) do not apply; and\n\n(C) A sample must be transported in a combination packaging that conforms to the requirements of this subchapter that are applicable to the tentative packing group assigned, and may not exceed a net mass of 2.5 kg (5.5 pounds) per package.\n\nFor the transportation of samples of self-reactive materials, organic peroxides, explosives or lighters,  see  \u00a7 173.224(c)(3), \u00a7 173.225(c)(2), \u00a7 173.56(d) or \u00a7 173.308(b)(2) of this subchapter, respectively.\n\n(12) Except when the proper shipping name in the Table is preceded by a plus (+)\u2014\n\n(i) If it is specifically determined that a material meets the definition of a hazard class, packing group or hazard zone, other than the class, packing group or hazard zone shown in association with the proper shipping name, or does not meet the defining criteria for a subsidiary hazard shown in Column 6 of the Table, the material shall be described by an appropriate proper shipping name listed in association with the correct hazard class, packing group, hazard zone, or subsidiary hazard for the material.\n\n(ii)  Generic or n.o.s. descriptions.  If an appropriate technical name is not shown in the Table, selection of a proper shipping name shall be made from the generic or n.o.s. descriptions corresponding to the specific hazard class, packing group, hazard zone, or subsidiary hazard, if any, for the material. The name that most appropriately describes the material shall be used,  e.g.,  an alcohol not listed by its technical name in the Table shall be described as \u201cAlcohol, n.o.s.\u201d rather than \u201cFlammable liquid, n.o.s.\u201d Some mixtures may be more appropriately described according to their application, such as \u201cCoating solution\u201d or \u201cExtracts, liquid, for flavor or aroma,\u201d rather than by an n.o.s. entry, such as \u201cFlammable liquid, n.o.s.\u201d It should be noted, however, that an n.o.s. description as a proper shipping name may not provide sufficient information for shipping papers and package markings. Under the provisions of subparts C and D of this part, the technical name of one or more constituents that makes the product a hazardous material may be required in association with the proper shipping name.\n\n(iii)  Multiple hazard materials.  If a material meets the definition of more than one hazard class, and is not identified in the Table specifically by name (e.g., acetyl chloride), the hazard class of the material shall be determined by using the precedence specified in \u00a7 173.2a of this subchapter, and an appropriate shipping description (e.g., \u201cFlammable liquid, corrosive n.o.s.\u201d) shall be selected as described in paragraph (c)(12)(ii) of this section.\n\n(iv) If it is specifically determined that a material is not a forbidden material and does not meet the definition of any hazard class, the material is not a hazardous material.\n\n(13)  Self-reactive materials and organic peroxides.  A generic proper shipping name for a self-reactive material or an organic peroxide, as listed in Column 2 of the Table, must be selected based on the material's technical name and concentration, in accordance with the provisions of \u00a7 173.224 or \u00a7 173.225 of this subchapter, respectively.\n\n(14) A proper shipping name that describes all isomers of a material may be used to identify any isomer of that material if the isomer meets criteria for the same hazard class or division, subsidiary risk(s) and packing group, unless the isomer is specifically identified in the Table.\n\n(15) Unless a hydrate is specifically listed in the Table, a proper shipping name for the equivalent anhydrous substance may be used, if the hydrate meets the same hazard class or division, subsidiary risk(s) and packing group.\n\n(16) Unless it is already included in the proper shipping name in the \u00a7 172.101 Table, the qualifying words \u201cliquid\u201d or \u201csolid\u201d may be added in association with the proper shipping name when a hazardous material specifically listed by name in the \u00a7 172.101 Table may, due to the differing physical states of the various isomers of the material, be either a liquid or a solid (for example \u201cDinitrotoluenes, liquid\u201d and \u201cDinitrotoluenes, solid\u201d). Use of the words \u201cliquid\u201d or \u201csolid\u201d is subject to the limitations specified for the use of the words \u201cmixture\u201d or \u201csolution\u201d in paragraph (c)(10) of this section. The qualifying word \u201cmolten\u201d may be added in association with the proper shipping name when a hazardous material, which is a solid in accordance with the definition in \u00a7 171.8 of this subchapter, is offered for transportation in the molten state (for example, \u201cAlkylphenols, solid, n.o.s., molten\u201d).\n\n(17) Unless it is already included in the proper shipping name in the \u00a7 172.101 Table, the qualifying word \u201cstabilized\u201d may be added in association with the proper shipping name, as appropriate, where without stabilization the substance would be forbidden for transportation according to \u00a7 173.21(f) of this subchapter.\n\n(d)  Column 3: Hazard class or Division.  Column 3 contains a designation of the hazard class or division corresponding to each proper shipping name, or the word \u201cForbidden\u201d.\n\n(1) A material for which the entry in this column is \u201cForbidden\u201d may not be offered for transportation or transported. This prohibition does not apply if the material is diluted, stabilized or incorporated in a device and it is classed in accordance with the definitions of hazardous materials contained in part 173 of this subchapter.\n\n(2) When a reevaluation of test data or new data indicates a need to modify the \u201cForbidden\u201d designation or the hazard class or packing group specified for a material specifically identified in the Table, this data should be submitted to the Associate Administrator.\n\n(3) A basic description of each hazard class and the section reference for class definitions appear in \u00a7 173.2 of this subchapter.\n\n(4) Each reference to a Class 3 material is modified to read \u201cCombustible liquid\u201d when that material is reclassified in accordance with \u00a7 173.150(e) or (f) of this subchapter or has a flash point above 60 \u00b0C (140 \u00b0F) but below 93 \u00b0C (200 \u00b0F).\n\n(e)  Column 4: Identification number.  Column 4 lists the identification number assigned to each proper shipping name. Those preceded by the letters \u201cUN\u201d are associated with proper shipping names considered appropriate for international transportation as well as domestic transportation. Those preceded by the letters \u201cNA\u201d are associated with proper shipping names not recognized for transportation outside of the United States. Identification numbers in the \u201cNA9000\u201d series are associated with proper shipping names not appropriately covered by international hazardous materials (dangerous goods) transportation standards, or not appropriately addressed by international transportation standards for emergency response information purposes, except for transportation in the United States. Those preceded by the letters \u201cID\u201d are associated with proper shipping names recognized by the ICAO Technical Instructions (see \u00a7 171.7 of this subchapter for availability).\n\n(f)  Column 5: Packing group.  Column 5 specifies one or more packing groups assigned to a material corresponding to the proper shipping name and hazard class for that material. Class 2, Class 7, and Division 6.2 do not have packing groups. Articles in classes other than Class 1 are not assigned to packing groups. For packing purposes, any requirement for a specific packaging performance level is set out in the applicable packing authorizations of part 173. Packing Groups I, II, and III indicate the degree of danger presented by the material is great, medium, or minor, respectively. If more than one packing group is indicated for an entry, the packing group for the hazardous material is determined using the criteria for assignment of packing groups specified in subpart D of part 173. When a reevaluation of test data or new data indicates a need to modify the specified packing group(s), the data should be submitted to the Associate Administrator. Each reference in this column to a material that is a hazardous waste or a hazardous substance, and whose proper shipping name preceded in Column 1 of the Table by the letter \u201cA\u201d or \u201cW,\u201d is modified to read \u201cIII\u201d on those occasions when the material is offered for transportation or transported by a mode in which its transportation is not otherwise subject to requirements of this subchapter.\n\n(g)  Column 6: Labels.  Column 6 specifies codes which represent the hazard warning labels required for a package filled with a material conforming to the associated hazard class and proper shipping name, unless the package is otherwise excepted from labeling by a provision in subpart E of this part, or part 173 of this subchapter. The first code is indicative of the primary hazard of the material. Additional label codes are indicative of subsidiary hazards. Provisions in \u00a7 172.402 may require that a label other than that specified in Column 6 be affixed to the package in addition to that specified in Column 6. No label is required for a material classed as a combustible liquid or for a Class 3 material that is reclassed as a combustible liquid. For \u201cEmpty\u201d label requirements, see \u00a7 173.428 of this subchapter. The codes contained in Column 6 are defined according to the following table:\n\nLabel Substitution Table\n\n1  Refers to the appropriate compatibility group letter.\n\n2  The packing group for a material is indicated in column 5 of the table.\n\n(h)  Column 7: Special provisions.  Column 7 specifies codes for special provisions applicable to hazardous materials. When Column 7 refers to a special provision for a hazardous material, the meaning and requirements of that special provision are as set forth in \u00a7 172.102 of this subpart.\n\n(i)  Column 8: Packaging authorizations.  Columns 8A, 8B and 8C specify the applicable sections for exceptions, non-bulk packaging requirements and bulk packaging requirements, respectively, in part 173 of this subchapter. Columns 8A, 8B and 8C are completed in a manner which indicates that \u201c\u00a7 173.\u201d precedes the designated numerical entry. For example, the entry \u201c202\u201d in Column 8B associated with the proper shipping name \u201cGasoline\u201d indicates that for this material conformance to non-bulk packaging requirements prescribed in \u00a7 173.202 of this subchapter is required. When packaging requirements are specified, they are in addition to the standard requirements for all packagings prescribed in \u00a7 173.24 of this subchapter and any other applicable requirements in subparts A and B of part 173 of this subchapter.\n\n(1) Exceptions. Column 8A contains exceptions from some of the requirements of this subchapter. The referenced exceptions are in addition to those specified in subpart A of part 173 and elsewhere in this subchapter. A \u201cNone\u201d in this column means no packaging exceptions are authorized, except as may be provided by special provisions in Column 7.\n\n(2) Non-bulk packaging. Column 8B references the section in part 173 of this subchapter which prescribes packaging requirements for non-bulk packagings. A \u201cNone\u201d in this column means non-bulk packagings are not authorized, except as may be provided by special provisions in Column 7. Each reference in this column to a material which is a hazardous waste or a hazardous substance, and whose proper shipping name is preceded in Column 1 of the Table by the letter \u201cA\u201d or \u201cW\u201d, is modified to include \u201c\u00a7 173.203\u201d or \u201c\u00a7 173.213\u201d, as appropriate for liquids and solids, respectively, on those occasions when the material is offered for transportation or transported by a mode in which its transportation is not otherwise subject to the requirements of this subchapter.\n\n(3)  Bulk packaging.  Column (8C) specifies the section in part 173 of this subchapter that prescribes packaging requirements for bulk packagings, subject to the limitations, requirements, and additional authorizations of Columns (7) and (8B). A \u201cNone\u201d in Column (8C) means bulk packagings are not authorized, except as may be provided by special provisions in Column (7) and in packaging authorizations Column (8B). Additional authorizations and limitations for use of UN portable tanks are set forth in Column 7. For each reference in this column to a material that is a hazardous waste or a hazardous substance, and whose proper shipping name is preceded in Column 1 of the Table by the letter \u201cA\u201d or \u201cW\u201d and that is offered for transportation or transported by a mode in which its transportation is not otherwise subject to the requirements of this subchapter:\n\n(i) The column reference is \u00a7 173.240 or \u00a7 173.241, as appropriate.\n\n(ii) For a solid material, the exception provided in special provision B54 is applicable.\n\n(iii) For a Class 9 material, which meets the definition of an elevated temperature material, the column reference is \u00a7 173.247.\n\n(4) For a hazardous material which is specifically named in the Table and whose packaging sections specify packagings not applicable to the form of the material (e.g., packaging specified is for solid material and the material is being offered for transportation in a liquid form) the following table should be used to determine the appropriate packaging section:\n\n(5)  Cylinders.  For cylinders, both non-bulk and bulk packaging authorizations are set forth in Column (8B). Notwithstanding a designation of \u201cNone\u201d in Column (8C), a bulk cylinder may be used when specified through the section reference in Column (8B).\n\n(j)  Column 9: Quantity limitations.  Columns 9A and 9B specify the maximum quantities that may be offered for transportation in one package by passenger-carrying aircraft or passenger-carrying rail car (Column 9A) or by cargo aircraft only (Column 9B), subject to the following:\n\n(1) \u201cForbidden\u201d means the material may not be offered for transportation or transported in the applicable mode of transport.\n\n(2) The quantity limitation is \u201cnet\u201d except where otherwise specified, such as for \u201cConsumer commodity\u201d which specifies \u201c30 kg gross.\u201d\n\n(3) When articles or devices are specifically listed by name, the net quantity limitation applies to the entire article or device (less packaging and packaging materials) rather than only to its hazardous components.\n\n(4) A package offered or intended for transportation by aircraft and which is filled with a material forbidden on passenger-carrying aircraft but permitted on cargo aircraft only, or which exceeds the maximum net quantity authorized on passenger-carrying aircraft, shall be labelled with the CARGO AIRCRAFT ONLY label specified in \u00a7 172.448 of this part.\n\n(5) The total net quantity of hazardous material for an outer non-bulk packaging that contains more than one hazardous material may not exceed the lowest permitted maximum net quantity per package as shown in Column 9A or 9B, as appropriate. If one material is a liquid and one is a solid, the maximum net quantity must be calculated in kilograms.  See  \u00a7 173.24a(c)(1)(iv).\n\n(k)  Column 10: Vessel stowage requirements.  Column 10A [Vessel stowage] specifies the authorized stowage locations on board cargo and passenger vessels.

Refer to the EPA Table 302.4\u2014List of Hazardous Substances and Reportable Quantities for an explanation of the two entries.\n\nTable 2 to Appendix A\u2014Radionuclides\n\n$ The RQs for all radionuclides apply to chemical compounds containing the radionuclides and elemental forms regardless of the diameter of pieces of solid material.\n\n\u2020 The RQ of one curie applies to all radionuclides not otherwise listed. Whenever the RQs in TABLE 1\u2014HAZARDOUS SUBSTANCES OTHER THAN RADIONUCLIDES and this table conflict, the lowest RQ shall apply. For example, uranyl acetate and uranyl nitrate have RQs shown in TABLE 1 of 100 pounds, equivalent to about one-tenth the RQ level for uranium-238 in this table.\n\n** The method to determine the RQs for mixtures or solutions of radionuclides can be found in paragraph 7 of the note preceding TABLE 1 of this appendix. RQs for the following four common radionuclide mixtures are provided: radium-226 in secular equilibrium with its daughters (0.053 curie); natural uranium (0.1 curie); natural uranium in secular equilibrium with its daughters (0.052 curie); and natural thorium in secular equilibrium with its daughters (0.011 curie).\n\n*** Indicates that the name was added by PHMSA because it appears in the list of radionuclides in 49 CFR 173.435. The reportable quantity (RQ), if not specifically listed elsewhere in this appendix, shall be determined in accordance with the procedures in paragraph 7 of this appendix.\n\nAppendix B to \u00a7 172.101\u2014List of Marine Pollutants\n \n 1.

The organic peroxide must be type D, E, or F, not requiring temperature control. The components may be placed in the same outer packaging provided they will not interact dangerously in the event of leakage. The Packing Group assigned will be II or III, according to the classification criteria for either Class 3 or Division 4.1, as appropriate, applied to the base material. Additionally, unless otherwise excepted in this subchapter, polyester resin kits must be packaged in specification combination packagings based on the performance level of the base material contained within the kit.\n \n 41 This material at the Packing Group II hazard criteria level may be transported in Large Packagings.\n \n 43 The membrane filters, including paper separators and coating or backing materials, that are present in transport, must not be able to propagate a detonation as tested by one of the tests described in the UN Manual of Tests and Criteria, Part I, Test series 1(a) (IBR, see \u00a7 171.7 of this subchapter). On the basis of the results of suitable burning rate tests, and taking into account the standard tests in the UN Manual of Tests and Criteria, Part III, subsection 33.2.1 (IBR, see \u00a7 171.7 of this subchapter), nitrocellulose membrane filters in the form in which they are to be transported that do not meet the criteria for a Division 4.1 material are not subject to the requirements of this subchapter. Packagings must be so constructed that explosion is not possible by reason of increased internal pressure. Nitrocellulose membrane filters covered by this entry, each with a mass not exceeding 0.5 g, are not subject to the requirements of this subchapter when contained individually in an article or a sealed packet.\n \n 44 The formulation must be prepared so that it remains homogenous and does not separate during transport. Formulations with low nitrocellulose contents and neither showing dangerous properties when tested for their ability to detonate, deflagrate or explode when heated under defined confinement by the appropriate test methods and criteria in the UN Manual of Tests and Criteria (IBR, see \u00a7 171.7 of this subchapter), nor classed as a Division 4.1 (flammable solid) when tested in accordance with the procedures specified in \u00a7 173.124 of this subchapter (chips, if necessary, crushed and sieved to a particle size of less than 1.25 mm), are not subject to the requirements of this subchapter.\n \n 45 Temperature should be maintained between 18 \u00b0C (64.4 \u00b0F) and 40 \u00b0C (104 \u00b0F).

Mass detonate means more than 90 percent of the devices tested in a package explode practically simultaneously. Limited propagation means that if one booster near the center of the package is exploded, the aggregate weight of explosives, excluding ignition and delay charges, in this and all additional boosters in the outside packaging that explode may not exceed 25 g.\n \n 116 Fuzes, detonating may be classed in Division 1.4 if the fuzes do not contain more than 25 g of explosive per fuze and are made and packaged so that they will not cause functioning of other fuzes, explosives or other explosive devices if one of the fuzes detonates in a shipping packaging or in adjacent packages.\n \n 117 If shipment of the explosive substance is to take place at a time that freezing weather is anticipated, the water contained in the explosive substance must be mixed with denatured alcohol so that freezing will not occur.\n \n 118 This substance may not be transported under the provisions of Division 4.1 unless specifically authorized by the Associate Administrator (see UN0143 or UN0150 as appropriate).\n \n 119 This substance, when in quantities of not more than 11.5 kg (25.3 pounds), with not less than 10 percent water, by mass, also may be classed as Division 4.1, provided a negative test result is obtained when tested in accordance with test series 6(c) of the UN Manual of Tests and Criteria (IBR, see \u00a7 171.7 of this subchapter). \n \n 120 The phlegmatized substance must be significantly less sensitive than dry PETN.\n \n 121 This substance, when containing less alcohol, water or phlegmatizer than specified, may not be transported unless approved by the Associate Administrator.\n \n 123 Any explosives, blasting, type C containing chlorates must be segregated from explosives containing ammonium nitrate or other ammonium salts.\n \n 125 Lactose or glucose or similar materials may be used as a phlegmatizer provided that the substance contains not less than 90%, by mass, of phlegmatizer. These mixtures may be classified in Division 4.1 when tested in accordance with test series 6(c) of the UN Manual of Tests and Criteria (IBR, see \u00a7 171.7 of this subchapter) and approved by the Associate Administrator. Testing must be conducted on at least three packages as prepared for transport. Mixtures containing at least 98%, by mass, of phlegmatizer are not subject to the requirements of this subchapter. Packages containing mixtures with not less than 90% by mass, of phlegmatizer need not bear a POISON subsidiary risk label.\n \n 127 Mixtures containing oxidizing and organic materials transported under this entry may not meet the definition and criteria of a Class 1 material. (See \u00a7 173.50 of this subchapter.)\n \n 128 Regardless of the provisions of \u00a7 172.101(c)(12), aluminum smelting by-products and aluminum remelting by-products described under this entry, meeting the definition of Class 8, Packing Group II and III may be classed as a Division 4.3 material and transported under this entry. The presence of a Class 8 hazard must be communicated as required by this part for subsidiary hazards.\n \n 129 These materials may not be classified and transported unless authorized by the Associate Administrator on the basis of results from Series 2 Test and a Series 6(c) Test from the UN Manual of Tests and Criteria (IBR, see \u00a7 171.7 of this subchapter) on packages as prepared for transport. The packing group assignment and packaging must be approved by the Associate Administrator for Hazardous Materials Safety on the basis of the criteria in \u00a7 173.21 of this subchapter and the package type used for the Series 6(c) test.\n \n 130 \u201cBatteries, dry, sealed, n.o.s.,\u201d commonly referred to as dry batteries, are hermetically sealed and generally utilize metals (other than lead) and/or carbon as electrodes. These batteries are typically used for portable power applications. The rechargeable (and some non-rechargeable) types have gelled alkaline electrolytes (rather than acidic) making it difficult for them to generate hydrogen or oxygen when overcharged and therefore, differentiating them from non-spillable batteries. Dry batteries specifically covered by another entry in the \u00a7 172.101 Table must be transported in accordance with the requirements applicable to that entry. For example, nickel-metal hydride batteries transported by vessel in certain quantities are covered by another entry ( see  Batteries, nickel-metal hydride, UN3496). Dry batteries not specifically covered by another entry in the \u00a7 172.101 Table are covered by this entry ( i.e.,  Batteries, dry, sealed, n.o.s.) and are not subject to requirements of this subchapter except for the following:\n \n (a)  Incident reporting.  For transportation by aircraft, a telephone report in accordance with \u00a7 171.15(a) is required if a fire, violent rupture, explosion or dangerous evolution of heat ( i.e.,  an amount of heat sufficient to be dangerous to packaging or personal safety to include charring of packaging, melting of packaging, scorching of packaging, or other evidence) occurs as a direct result of a dry battery. For all modes of transportation, a written report submitted, retained, and updated in accordance with \u00a7 171.16 is required if a fire, violent rupture, explosion or dangerous evolution of heat occurs as a direct result of a dry battery or battery-powered device.\n \n (b)  Preparation for transport.  Batteries and battery-powered device(s) containing batteries must be prepared and packaged for transport in a manner to prevent:\n \n (1) A dangerous evolution of heat;\n \n (2) Short circuits, including but not limited to the following methods:\n \n (i) Packaging each battery or each battery-powered device when practicable, in fully enclosed inner packagings made of non-conductive material;\n \n (ii) Separating or packaging batteries in a manner to prevent contact with other batteries, devices or conductive materials ( e.g.,  metal) in the packagings; or\n \n (iii) Ensuring exposed terminals or connectors are protected with non-conductive caps, non-conductive tape, or by other appropriate means; and\n \n (3) Damage to terminals. If not impact resistant, the outer packaging should not be used as the sole means of protecting the battery terminals from damage or short circuiting. Batteries must be securely cushioned and packed to prevent shifting which could loosen terminal caps or reorient the terminals to produce short circuits. Batteries contained in devices must be securely installed. Terminal protection methods include but are not limited to the following:\n \n (i) Securely attaching covers of sufficient strength to protect the terminals;\n \n (ii) Packaging the battery in a rigid plastic packaging; or\n \n (iii) Constructing the battery with terminals that are recessed or otherwise protected so that the terminals will not be subjected to damage if the package is dropped.\n \n (c)  Additional air transport requirements.  For a battery whose voltage (electrical potential) exceeds 9 volts\u2014\n \n (1) When contained in a device, the device must be packaged in a manner that prevents unintentional activation or must have an independent means of preventing unintentional activation ( e.g.,  packaging restricts access to activation switch, switch caps or locks, recessed switches, trigger locks, temperature sensitive circuit breakers,  etc. ); and\n \n (2) An indication of compliance with this special provision must be provided by marking each package with the words \u201cnot restricted\u201d or by including the words \u201cnot restricted\u201d on a transport document such as an air waybill accompanying the shipment.\n \n (d)  Used or spent battery exception.  Used or spent dry batteries of both non-rechargeable and rechargeable designs, with a marked rating up to 9-volt that are combined in the same package and transported by highway or rail for recycling, reconditioning, or disposal are not subject to this special provision or any other requirement of the HMR. Note that batteries utilizing different chemistries ( i.e.,  those battery chemistries specifically covered by another entry in the \u00a7 172.101 Table) as well as dry batteries with a marked rating greater than 9-volt may not be combined with used or spent batteries in the same package. Note also that this exception does not apply to batteries that have been reconditioned for reuse.\n \n 131 This material may not be offered for transportation unless approved by the Associate Administrator.\n \n 132 This description may only be used for ammonium nitrate-based compound fertilizers. They must be classified in accordance with the procedure as set out in the Manual of Tests and Criteria, part III, section 39 (IBR,  see  \u00a7 171.7 of this subchapter).

Mass detonate means more than 90 percent of the devices tested in a package explode practically simultaneously. Limited propagation means that if one booster near the center of the package is exploded, the aggregate weight of explosives, excluding ignition and delay charges, in this and all additional boosters in the outside packaging that explode may not exceed 25 g.\n\n116 Fuzes, detonating may be classed in Division 1.4 if the fuzes do not contain more than 25 g of explosive per fuze and are made and packaged so that they will not cause functioning of other fuzes, explosives or other explosive devices if one of the fuzes detonates in a shipping packaging or in adjacent packages.\n\n117 If shipment of the explosive substance is to take place at a time that freezing weather is anticipated, the water contained in the explosive substance must be mixed with denatured alcohol so that freezing will not occur.\n\n118 This substance may not be transported under the provisions of Division 4.1 unless specifically authorized by the Associate Administrator (see UN0143 or UN0150 as appropriate).\n\n119 This substance, when in quantities of not more than 11.5 kg (25.3 pounds), with not less than 10 percent water, by mass, also may be classed as Division 4.1, provided a negative test result is obtained when tested in accordance with test series 6(c) of the UN Manual of Tests and Criteria (IBR, see \u00a7 171.7 of this subchapter).\n\n120 The phlegmatized substance must be significantly less sensitive than dry PETN.\n\n121 This substance, when containing less alcohol, water or phlegmatizer than specified, may not be transported unless approved by the Associate Administrator.\n\n123 Any explosives, blasting, type C containing chlorates must be segregated from explosives containing ammonium nitrate or other ammonium salts.\n\n125 Lactose or glucose or similar materials may be used as a phlegmatizer provided that the substance contains not less than 90%, by mass, of phlegmatizer. These mixtures may be classified in Division 4.1 when tested in accordance with test series 6(c) of the UN Manual of Tests and Criteria (IBR, see \u00a7 171.7 of this subchapter) and approved by the Associate Administrator. Testing must be conducted on at least three packages as prepared for transport. Mixtures containing at least 98%, by mass, of phlegmatizer are not subject to the requirements of this subchapter. Packages containing mixtures with not less than 90% by mass, of phlegmatizer need not bear a POISON subsidiary risk label.\n\n127 Mixtures containing oxidizing and organic materials transported under this entry may not meet the definition and criteria of a Class 1 material.

The presence of a Class 8 hazard must be communicated as required by this part for subsidiary hazards.\n\n129 These materials may not be classified and transported unless authorized by the Associate Administrator on the basis of results from Series 2 Test and a Series 6(c) Test from the UN Manual of Tests and Criteria (IBR, see \u00a7 171.7 of this subchapter) on packages as prepared for transport. The packing group assignment and packaging must be approved by the Associate Administrator for Hazardous Materials Safety on the basis of the criteria in \u00a7 173.21 of this subchapter and the package type used for the Series 6(c) test.\n\n130 \u201cBatteries, dry, sealed, n.o.s.,\u201d commonly referred to as dry batteries, are hermetically sealed and generally utilize metals (other than lead) and/or carbon as electrodes. These batteries are typically used for portable power applications. The rechargeable (and some non-rechargeable) types have gelled alkaline electrolytes (rather than acidic) making it difficult for them to generate hydrogen or oxygen when overcharged and therefore, differentiating them from non-spillable batteries. Dry batteries specifically covered by another entry in the \u00a7 172.101 Table must be transported in accordance with the requirements applicable to that entry. For example, nickel-metal hydride batteries transported by vessel in certain quantities are covered by another entry ( see  Batteries, nickel-metal hydride, UN3496). Dry batteries not specifically covered by another entry in the \u00a7 172.101 Table are covered by this entry ( i.e.,  Batteries, dry, sealed, n.o.s.) and are not subject to requirements of this subchapter except for the following:\n\n131 This material may not be offered for transportation unless approved by the Associate Administrator.\n\n132 This description may only be used for ammonium nitrate-based compound fertilizers.

(1) Except as provided in \u00a7 172.332 of this part, each placard must be as described in this subpart, and except for size and color, the printing, inner border and symbol must be as shown in \u00a7\u00a7 172.521 through 172.560 of this subpart, as appropriate.\n\n(2) The dotted line border shown on each placard is not part of the placard specification. However, a dotted or solid line outer border may be used when needed to indicate the full size of a placard that is part of a larger format or is on a background of a non-contrasting color.\n\n(3) For other than Class 7 or the DANGEROUS placard, text indicating a hazard (for example, \u201cFLAMMABLE\u201d) is not required. Text may be omitted from the OXYGEN placard only if the specific identification number is displayed on the placard.\n\n(4) For a placard corresponding to the primary or subsidiary hazard class of a material, the hazard class or division number must be displayed in the lower corner of the placard. However, a permanently affixed subsidiary placard meeting the specifications of this section which were in effect on October 1, 2001, (such as, a placard without the hazard class or division number displayed in the lower corner of the placard) and which was installed prior to September 30, 2001, may continue to be used as a subsidiary placard in domestic transportation by rail or highway, provided the color tolerances are maintained and are in accordance with the display requirements in this subchapter.\n\n(c)  Size.  (1) Each diamond (square-on-point) placard prescribed in this subpart must measure at least 250 mm (9.84 inches) on each side and must have a solid line inner border approximately 12.5 mm inside and parallel to the edge. The 12.5 mm measurement is from the outside edge of the placard to the outside of the solid line forming the inner border. For domestic transportation, a placard manufactured prior to January 1, 2017, in conformance with the requirements of this paragraph in effect on December 31, 2014, may continue in service until the end of its useful life provided the color tolerances are maintained and are in accordance with the display requirements of this subchapter.\n\n(2) Except as otherwise provided in this subpart, the hazard class or division number, as appropriate, must be shown in numerals measuring at least 41 mm (1.6 inches) in height.\n\n(3) Except as otherwise provided in this subpart, when text indicating a hazard is displayed on a placard, the printing must be in letters measuring at least 41 mm (1.6 inches) in height.\n\n(d)  Color.  (1) The background color, symbol, text, numerals and inner border on a placard must be as specified in \u00a7\u00a7 172.521 through 172.560 of this subpart, as appropriate.\n\n(2) Black and any color on a placard must be able to withstand, without substantial change\u2014\n\n(i) A 72-hour fadeometer test (for a description of equipment designed for this purpose, see ASTM G 23-69 or ASTM G 26-70); and\n\n(ii) A 30-day exposure to open weather.\n\n(3) Upon visual examination, a color on a placard must fall within the color tolerances displayed on the appropriate Hazardous Materials Label and Placard Color Tolerance Chart (see \u00a7 172.407(d)(4)). As an alternative, the PANTONE \u00ae formula guide coated/uncoated as specified for colors in \u00a7 172.407(d)(5) may be used.\n\n(4) The placard color must extend to the inner border and may extend to the edge of the placard in the area designated on each placard except the color on the CORROSIVE and RADIOACTIVE placards (black and yellow, respectively) must extend only to the inner border.\n\n(e)  Form identification.  A placard may contain form identification information, including the name of its maker, provided that information is printed outside of the solid line inner border in no larger than 10-point type.\n\n(f)  Exceptions.  When hazardous materials are offered for transportation or transported under the provisions of subpart C of part 171 of this subchapter, a placard conforming to the specifications in the UN Recommendations, the ICAO Technical Instructions, the IMDG Code, or the Transport Canada TDG Regulations (IBR, see \u00a7 171.7 of this subchapter) may be used in place of a corresponding placard conforming to the requirements of this subpart. However, a bulk packaging, transport vehicle, or freight container containing a material poisonous by inhalation (see \u00a7 171.8 of this subchapter) must be placarded in accordance with this subpart (see \u00a7 171.23(b)(10) of this subchapter).\n\n(g)  Trefoil symbol.
