You ask about a paint kit that is comprised of two different hazardous materials that are individually packaged and then placed in a single drum, which functions as the outer packaging of a combination packaging. Specifically, you ask whether the requirement to indicate the number and type of packages as part of the shipping description—as specified in § 172.202(a)(7)—is fulfilled by indicating that the shipment contains one package (i.e., a drum) for the entire consignment (i.e., paint kit) as shown below: # Packages HM Quantity Pack Description Classification Description Weight 1 X 3.79 L ALL ONE UN2735, AMINES, LIQUID, 9 LBS DRUM CORROSIVE, N.O.S. (FATTY ACIDES, TALL OIL, REACTION PRODUCTS WITH TETRAETHYLPENTAMINE, TETRAETYHLYPENTAMINE), 8, PGIII 15.14 L UN1263, PAINT, 3, PGIII 91 LBS The answer is yes. It is the opinion of this Office that for a combination package, it is appropriate to list the outer packaging as the package type on the shipping paper. Additionally, where <<>> multiple hazardous materials described by differing § 172.101 Hazardous Materials Table entries are contained in a combination packaging, they should be entered on sequential rows so that the total quantity associated with each description is clearly identified. I hope this information is helpful. Please contact us if we can be of further assistance.
