Specifically, you ask how Resin Solution containing Di(4-tert-butylcyclohexyl) Peroxydicarbonate and Tert-Butyl Peroxybenzoate in a felt/glass constructed liner with a thin film coating should be classified. Your understanding is that the compound resin product in a felt/glass constructed liner should be classified as "Resin Solution, UN 1866, Class 3, PG III." As specified in§ 173.22 of the HMR, a shipper is responsible for properly classifying, packaging, marking, and labeling a hazardous material for transportation in commerce. This Office does not typically perform this function. The hazard class of a material is determined based on the chemical composition and hazard properties of the material. If your material meets the definition of any of the hazard classes or is a hazardous substance, a marine pollutant or a hazardous waste, it is regulated under the HMR. Therefore, if the material you have described remains in its liquid form, it should continue to be classified as a "Resin Solution, UN 1866, Class 3, PG III." I hope this satisfies your inquiry. Please contact us if we can be of further assistance. Sincerely, T. Glenn Foster Chief, Regulatory Review and Reinvention Branch Standards and Rulemaking Division#
