Which of the following is NOT one of the required elements of a hazardous materials shipping description on the shipping paper?

49 CFR 172.202; 172.604; AAMVA CDL Manual, Section 9.3.4/9.3.5 (nhcdm.pdf p. 9-6/9-7)

The six required shipping-description elements (ID number, proper shipping name, hazard class, packing group, quantity, and 24-hour emergency phone number) exist so that any first responder, anywhere, can identify exactly what's on the truck without knowing anything about the driver or carrier — the description has to stand on its own.
