In your\nemail, you present a scenario where tert-Butyl hydroperoxide is transported as “UN3103,\nOrganic peroxide type C, liquid, 5.2” which is listed in the Hazardous Materials Table (HMT;\n§ 172.101) as a Division 5.2 material with no subsidiary hazard. However, you note that Note 13\nin Column 8 of the Organic Peroxide Table found in § 173.225 indicates that tert-Butyl\nhydroperoxide requires an additional Class 8 (corrosive) label, in addition to the Division 5.2\nlabel. You ask whether your understanding is correct that a shipment of “UN3103” comprised of\ntert-Butyl hydroperoxide requires both a Division 5.2 label and a subsidiary Class 8 label.\nYou are correct that the HMT does not list “UN3103, Organic peroxide type C, liquid, 5.2” with\na Class 8 subsidiary hazard. However, as noted in your email, the Organic Peroxide Table in\n§ 173.225 requires tert-Butyl hydroperoxide to have a subsidiary Class 8 (corrosive) label.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nT.
