Reference No. 19-0133

Dear Mr. Canterbury:

This letter is in response to your December 12, 2019, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the proper shipping name for a compound containing a mixture of hydrocarbons. You state that the safety data sheet (SDS) you included in your email lists the technical names as "(Lithium Diisopropylamide, Heptane (C7 hydrocarbon mixture))." Specifically, you ask whether the words "C7 hydrocarbon mixture" must appear as a part of the hazmat shipping description on the shipping paper.

The answer is no. The addition of "C7 hydrocarbon mixture" is not required because it is redundant with the listed technical name Heptane. Note that technical names must be included in parentheses with the hazardous material shipping description and generally, at least two components which most predominantly contribute to the hazard(s) of the mixture or solution must be entered on the shipping paper. See § 172.203(k).

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

Sincerely,

Dirk Der Kinderen
Chief, Standards Development Branch
Standards and Rulemaking Division
