Dear Ms. Williams:

This responds to your letter, dated October 31, 2000, concerning transportation of lithium hydroxide under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically, you ask if you may rename a technically pure shipment of lithium hydroxide as a lithium hydroxide mixture or a corrosive solid mixture, n.o.s., in order to protect a trade secret.

The answer is no.  As defined in the HMR, a "mixture"  means a material composed of more than one chemical compound or element (see § 171.8). Technically pure lithium hydroxide is not a mixture and may not be so described on a shipping paper.  Further, generic shipping names, such as corrosive solid, n.o.s., are to be used only for hazardous materials not specifically listed by name in the Hazardous Materials Table.  As your letter notes, lithium hydroxide, solid, is listed in Column (2) of the table.  Thus, the shipping description for technically pure lithium hydroxide is: Lithium hydroxide, solid, 8, UN 2680, PG II.

I hope this information is helpful.  If you have further questions, please do not hesitate to contact this office.
