No.: 05-0282 Manager Transportation Regulations and Security Akzo Nobel Chemicals Inc 300 South Riverside Plaza Chicago, IL 60606-6697 Dear Mr. Connolly: This is in response to your October 19, 2005 letter regarding entry of the subsidiary hazard class or division on shipping papers under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Your questions are paraphrased and answered as follows: Q1. Under § 172.202(a), the subsidiary hazard class or division must be entered in parentheses immediately following the primary hazard class on shipping papers. in Column 6 of the § 172.101 Table? Does this requirement only apply to subsidiary hazard classes when specifically noted Al. No. If it is specifically determined that a material meets the defining criteria for a subsidiary hazard that is not shown in Column 6 of the § 172.101 Table for that material, the material must be identified on the shipping paper as having that subsidiary hazard class in accordance with § 172.202(a). Q2. Is the notation "(1)" as the subsidiary hazard entry on a shipping paper acceptable for a material identified in Column 6 of the § 172.101 Table as having an explosive subsidiary hazard? A2. Yes. A material identified in Column 6 of the § 172.101 Table as Caving an explosive subsidiary hazard is not assigned to a specific division or compatibility group. Therefore, the number "1" placed in parentheses is the appropriate subsidiary hazard class entry on the shipping paper. I hope this information is helpful. If you have further questions, please do not hesitate to contact this office. Sincerely Hatte z. Mthell Hattie L.
