Reference No. 21-0029

Dear Mr. Shoemake:

This letter is in response to your March 17, 2021, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to bulk packaging requirements for low hazard materials as specified in § 173.241. Specifically, you ask whether you may transport "UN3264, Corrosive liquid, acidic, inorganic, n.o.s, 8, PG III" in a non-specification cargo tank motor vehicle that is suitable for transporting liquids.

The answer is yes. Column (8C) of the Hazardous Materials Table (HMT; § 172.101) prescribes requirements for bulk packagings for a given material, subject to limitations, requirements, and additional authorizations of Columns (7) and (8B). The HMT entry for "UN3264, Corrosive liquid, acidic, inorganic, n.o.s, 8, PG III," lists § 173.241 in Column (8C), which authorizes bulk packagings for certain low hazard liquid and solid materials. In addition to various DOT specification cargo tank motor vehicles, § 173.241(b) also permits the use of non-DOT specification cargo tank motor vehicles suitable for the transport of liquids. Please note that although a non-DOT specification cargo tank motor vehicle is authorized, it is your responsibility to determine whether it is compatible with the lading per § 173.24(e).

I hope this information is helpful. Please contact us if we can be of further assistance.

Sincerely,

T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division
