No. 05-0167 Hazardous Materials Specialist Boasso America Corporation 100 Intermodal Drive Chalmette, Louisiana 70043 Dear Mr. Ortego: This responds to your June 24, 2005 letter requesting clarification on shipping hazardous materials in a portable tank as a bulk export shipment from the port of New Orleans under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask for clarification on the proper shipping name and hazard class for your material, as well as the required markings and placarding for the portable tank. According to your letter, you are shipping a bulk quantity of a material that meets the defining criteria for a combustible liquid, UN 1993, as well as an environmentally hazardous substance and a marine pollutant for alkyl-(C3-C5)-benzene and solvent naptha. You also state that the portable tank is currently being marked and placarded as a Class 9, Marine Pollutant, and bears no markings as a Combustible liquid, NA 1993. In accordance with § 173.22, it is the shipper's responsibility to properly class and describe a hazardous material for transportation. This Office does not perform that function. However, it is the opinion of this Office that the proper shipping description for your material would be 'Combustible liquid, n.o.s., NA 1993' under the HMR. It is also the opinion of this Office that in accordance with the International Maritime Dangerous Goods (IMDG) Code, the proper shipping description would be "Environmentally azardous substances, liquid, n.o.s., 9, UN 3082, PG IIl'. Both entries require a technica ame. If a reportable quantity of a listed environmentally hazardous substance i the package. For domestic transportation, the portable tank must be marked in accordance with 58172302, 13220) d the Ho The porsche tank mant be placate the MIDG 173.22 050167 <<>> accordance with § 172.504. Placarding is not required for Class 9 materials when shipped domestically. I hope this answers your inquiry.
