No. 07-0067R\n1050 Sycamore Rd.\nManteno, II 60950\nMr. Meeks:\nThis is in further response to our July 28, 2007 reply to your March 30, 2007 letter concerning\nlimited quantity shipments of compressed gases transported by highway. A further review of\nthis issue indicates a need to clarify our previous response.\nYour letter stated that § 173.306 of the Hazardous Materials Regulations (HMR; 49 CFR Parts\n171-180) provides labeling and packaging exceptions for compressed gases only when offered\nas a limited quantity not exceeding a gross weight of 30 kg (66 pounds). Your letter also stated\nthat a 55-gallon steel drum (1A2) used as an outer packaging to contain aerosols and having a\napplicable labeling and packaging requirements are maintained. You asked whether your\ngross weight over 30 kg (66 pounds) may be offered and transported by highway, provided all\ninterpretations were correct.\nIn our response, we indicated that when transported by highway, § 173.306 excepts limited\ntransportation by air); and (2) specification packaging requirements when packaged in\nquantities of certain compressed gases from: (1) labeling (except when intended for further\naccordance with paragraphs (a)(1) through (a)(4) of § 173.306, unless required as a condition of\nthe exception. Each package may not exceed 30 kg (66 pounds) gross weight. In addition,\nthese shipments are not subject to: subpart F (Placarding) of part 172; part 174, except\n§ 174.24; and part 177, except § 177.817.\nIt was not out intention to imply that a 55-gallon steel drum is an acceptable packaging for\n\"Exceptions\" column of the HMT. The HMR does not authorize aerosols to be transported in a\naerosols. The only packaging section for this material is § 173.306 as indicated under the\npackage with a gross weight that is greater then 30 kg (66 pounds).\nI hope this information is helpful.\nSincerely,\nChief.
