Harmonization With the United Nations Recommendations, International Maritime Dangerous Goods Code, and International Civil Aviation Organization's Technical Instructions; Correction; Final Rule

On December 20, 2004, the Research and Special Programs Administration (RSPA)--the predecessor agency to the Pipeline and Hazardous Materials Safety Administration (PHMSA)--published a final rule under Docket Number RSPA-04-17036 (HM-215G) amending the Hazardous Materials Regulations (HMR) to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations and vessel stowage requirements. Because of recent changes to the International Maritime Dangerous Goods Code (IMDG Code), the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions), and the United Nations Recommendations on the Transport of Dangerous Goods (UN Recommendations), these revisions are necessary to facilitate the transport of hazardous materials in international commerce. This final rule corrects errors in the December 20, 2004 final rule.
