§172.301. General marking requirements for non-bulk packagings. — Inbound Citations

(a) Except for an article or substance of Class 7 prepared in accordance with subpart I of part 173, a package prepared in accordance with applicable limited quantity requirements in part 173 of this subchapter and offered for transportation by a mode other than air must display the limited quantity marking shown in paragraph (a)(1) of this section. A package displaying this mark is not subject to the marking requirements of § 172.301 of this subpart unless the limited quantity package also contains a hazardous substance or a hazardous waste. Required markings need not be duplicated if already marked as prescribed elsewhere in this subpart. As an alternative, a packaging may display the limited quantity “Y” mark shown in paragraph (b) of this section if the package conforms to authorized substance and article provisions and the inner and outer package quantity limits in § 173.27(f) of this subchapter.

(1) The top and bottom portions of the square-on-point and the border forming the square-on-point must be black and the center white or of a suitable contrasting background as follows:

(2) The square-on-point must be durable, legible and of a size relative to the packaging, readily visible, and must be applied on at least one side or one end of the outer packaging. The width of the border forming the square-on-point must be at least 2 mm and the minimum dimension of each side, as measured from the outside of the lines forming the border, must be 100 mm unless the packaging size requires a reduced size marking that must be no less than 50 mm on each side and the width of the border forming the square on point may be reduced to a minimum of 1 mm. Where dimensions are not specified, all features shall be in approximate proportion to those shown. When intended for transportation by vessel, a cargo transport unit (see § 176.2 of this subchapter) containing packages of hazardous materials in only limited quantities must be marked once on each side and once on each end of the exterior of the unit with an identical mark which must have minimum dimensions of 250 mm on each side.

(i) A marking in conformance with the requirements of this paragraph in effect on December 31, 2014, may continue to be used until December 31, 2016.

(ii) For domestic transportation, a packaging marked prior to January 1, 2017 and 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.

(3) Except for Class 1 and 7, and Division 6.1 and 6.2 materials, for highway transportation by private motor carrier, the limited quantity marking is not required to be displayed on a package containing materials assigned to Packing Group II and III prepared in accordance with the limited quantity requirements in subpart B of part 173 of this subchapter provided:

(i) Inner packagings for liquid hazardous materials do not exceed 1.0 L (0.3 gallons) net capacity each;

(ii) Inner packagings for solid hazardous materials do not exceed 1.0 kg (2.2 pounds) net capacity each;

(iii) No more than 2 L (0.6 gallons) or 2 kg (4.4 pounds) aggregate net quantity of any one hazardous material is transported per vehicle;

(iv) The total gross weight of all the limited quantity packages per vehicle does not exceed 60 kg (132 pounds); and

(v) Each package is marked with the name and address of the offeror, a 24-hour emergency response telephone number and the statement “Contains Chemicals” in letters at least 25 mm (one-inch) high on a contrasting background.

(a) When required by § 172.301, § 172.302, § 172.313, § 172.326, § 172.328, § 172.330, or § 172.331, identification number markings must be displayed on orange panels or placards as specified in this section, or on white square-on-point configurations as prescribed in § 172.336(b).

(d) The requirements for the inclusion of technical names for n.o.s. descriptions on shipping papers and package markings, §§ 172.203 and 172.301 of this subchapter, respectively, do not apply to packages prepared in accordance with paragraph (b) of this section, except that packages containing materials meeting the definition of a hazardous substance must be described as required in § 172.203 of this subchapter and marked as required in § 172.324 of this subchapter.

(2) Each inner plastic bottle, outer metal can, and barrier bag must be marked with: Chemical name; quantity; and the name and address of the offeror. Each outer packaging must be marked with the proper shipping name and identification number in conformance with § 172.301. Additionally, each outer packaging must be marked, “FOR TRANSPORT BY MOTOR VEHICLE ONLY.”

(A) Notwithstanding the marking requirements for non-bulk packages in § 172.301 of this subchapter, each drum must be marked “AEROSOL SALVAGE” or “AEROSOL SALVAGE DRUM” in association with the required label(s); and

(d) When a bulk packaging is labeled instead of placarded in accordance with § 172.514(c) of this subchapter, identification number markings may be displayed on the package in accordance with the marking requirements of § 172.301(a)(1) of this subchapter.

(4) For an intermediate bulk container (IBC) labeled in accordance with subpart E of this part, the IBC may display the proper shipping name and UN identification number markings in accordance with § 172.301(a)(1) in place of the UN number on an orange panel, placard, or white square-on-point configuration as prescribed in § 172.336(d). Additionally, IBCs containing a combustible liquid may be placarded with a combustible placard that meets the label specifications for size in § 172.407(c). However, a transport vehicle containing IBCs with a reduced-size combustible placard is still required to conform to the placarding requirements in this subpart, including the size requirements in § 172.519(c); and

(d) Hazardous materials offered for transportation and transported by private carrier in accordance with paragraph (c) of this section may use the marking “REVERSE LOGISTICS—HIGHWAY TRANSPORT ONLY—UNDER 49 CFR 173.157” as an alternative to the surface limited quantity marking found under § 172.315(a). Size marking requirements found in § 172.301(a)(1) apply.

(k) Unless otherwise excepted, if a material is described on a shipping paper by one of the proper shipping names identified by the letter “G” in column (1) of the § 172.101 Table, the technical name of the hazardous material must be entered in parentheses in association with the basic description. For example “UN 1760, Corrosive liquid, n.o.s., (Octanoyl chloride), 8, II”, or “UN 1760, Corrosive liquid, n.o.s., 8, II (contains Octanoyl chloride)”. The word “contains” may be used in association with the technical name, if appropriate. For organic peroxides which may qualify for more than one generic listing depending on concentration, the technical name must include the actual concentration being shipped or the concentration range for the appropriate generic listing. For example, “UN 3102, Organic peroxide type B, solid, 5.2, (dibenzoyl peroxide, 52-100%)” or “UN 3108, Organic peroxide type E, solid, 5.2, (dibenzoyl peroxide, paste, <52%)”. Shipping descriptions for toxic materials that meet the criteria of Division 6.1, PG I or II (as specified in § 173.132(a) of this subchapter) or Division 2.3 (as specified in § 173.115(c) of this subchapter) and are identified by the letter “G” in column (1) of the § 172.101 Table, must have the technical name of the toxic constituent entered in parentheses in association with the basic description. A material classed as Division 6.2 and assigned identification number UN 2814 or UN 2900 that is suspected to contain an unknown Category A infectious substance must have the words “suspected Category A infectious substance” entered in parentheses in place of the technical name as part of the proper shipping description. For additional technical name options, see the definition for “Technical name” in § 171.8. A technical name should not be marked on the outer package of a Division 6.2 material (see § 172.301(b)).

(1) If a hazardous material is a mixture or solution of two or more hazardous materials, the technical names of at least two components most predominately contributing to the hazards of the mixture or solution must be entered on the shipping paper as required by paragraph (k) of this section. For example, “UN 2924, Flammable liquid, corrosive, n.o.s., 3 (8), II (contains Methanol, Potassium hydroxide)”.

(i) To a material that is a hazardous waste and described using the proper shipping name “Hazardous waste, liquid or solid, n.o.s.”, classed as a miscellaneous Class 9, provided the EPA hazardous waste number is included on the shipping paper in association with the basic description, or provided the material is described in accordance with the provisions of § 172.203(c) of this part.

(ii) To a material for which the hazard class is to be determined by testing under the criteria in § 172.101(c)(11).

(iii) If the n.o.s. description for the material (other than a mixture of hazardous materials of different classes meeting the definitions of more than one hazard class) contains the name of the chemical element or group which is primarily responsible for the material being included in the hazard class indicated.

(iv) If the n.o.s. description for the material (which is a mixture of hazardous materials of different classes meeting the definition of more than one hazard class) contains the name of the chemical element or group responsible for the material meeting the definition of one of these classes. In such cases, only the technical name of the component that is not appropriately identified in the n.o.s. description shall be entered in parentheses.
