Dear Mr. Sanders:

This responds to your February 19, 2009 email requesting clarification of the classification and description of your product under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you request confirmation that you appropriately class and describe a solution of >99.0 % methanol and less than <1.0% 2,4-Dinitrophenol as "UN1230, Methanol solution, 3, II" and whether the product is eligible for small quantities exceptions.

Under § 173.22, it is the shipper"s responsibility to class a hazardous material. This Office does not normally perform this function. 2,4-Dinitrophenol is explosive when dry and requires approval from the Associate Administration prior to transport of the material. However, it is the opinion of this Office that your solution of <1.0% Dinitrophenol (UN0076) is sufficiently diluted so that it is not regulated as a Class 1 explosive or as a Class 3 desensitized explosive nor is it regulated as a Division 6.1 poisonous material. Therefore, "UN1230, Methanol, 3, II" is appropriate to describe your product and the product would be eligible for small quantity exceptions under § 173.4. We note that the qualifying word "solution" must not be added to the proper shipping name. For purposes of the HMR, use of the qualifying word applies to a solution comprised of a hazardous material identified in the § 172.101 Hazardous Materials Table (HMT) and a non-hazardous material.

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