Specifically, you ask whether your understanding is correct that a hazardous material—in your case “UN3103, Organic peroxide type C, liquid, 5.2, (tert- Butyl hydroperoxide, >79-90%)”—requires both a Division 5.2 hazard label and a Class 8 hazard label, when Column 8 (Notes) of the § 173.225 Table 1 to paragraph (c) - Organic Peroxide Table assigns a number “13.” Your understanding is correct. As indicated in § 173.225(c)(8), Column 8 specifies other applicable provisions, as set forth in the notes following the Table 1 to paragraph (c) - Organic Peroxide Table. Specifically, Note 13 states a corrosive subsidiary risk label is required. Therefore, any material listed in the table that is assigned “13” in Column 8 requires a Class 8 (corrosive) subsidiary hazard label, along with the primary hazard label. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, Dirk Der Kinderen Chief, Standards Development Branch Standards and Rulemaking Division <<>> Baker 22-0080 From: Casey, Candace (PHMSA) To: Dodd, Alice (PHMSA) Subject: FW: Clarification Letter of Interpretation Note 13 Organic Peroxide Table 49 CFR 173.225 Date: Monday, August 8, 2022 3:15:51 PM Attachments: Clarification Organic Peroxide Table Note 13 49 CFR 173.225.docx Hi Alice, I think this interp was never assigned.
