Dear Ms. Nese:

This is in response to your October 13, 2005 letter regarding determination of a proper shipping name for a sodium nitrite solution under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). According to your letter, the product you intend to offer for transportation does not meet the definition of a Division 5.1 material as defined in § 173,127 and is better classified as a Division 6.1 material and described as "Toxic liquid, inorganic, n.o.s. (sodium nitrite), 6.1, UN3287, PGIII." Specifically, you ask this office for consent to make this determination.

In accordance with § 173.22, it is the shipper"s responsibility to properly classify a hazardous material and assign it a proper shipping name from the hazardous material Table (HMT; § 172.101). Such determinations are not required to be verified by this Office. In accordance with § 172.101(c)(12)(i), if it is specifically determined that a material meets the definition of a hazard class, packing group or hazard zone, other than the class, packing group or hazard zone shown in association with the proper shipping name, or does not meet the defining criteria for a subsidiary hazard shown in Column 6 of the Table, the material must be described by an appropriate proper shipping name listed in association with the correct hazard class, packing group, hazard zone, or subsidiary hazard for the material. Provided the sodium nitrite you offer for transportation meets the definition of a Division 6.1 material, your classification is the most appropriate.

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