{"abstract":"PHMSA proposes to amend the Hazardous Materials Regulations to adopt certain international regulations and standards related to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. These amendments are intended to maintain consistency with the latest international standards and regulations, and to reduce costs to entities or individuals within the United States or to otherwise lower the cost of regulations on the United States economy.","action":"Notice of proposed rulemaking (NPRM).","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Pipeline and Hazardous Materials Safety Administration","name":"Pipeline and Hazardous Materials Safety Administration","id":408,"url":"https://www.federalregister.gov/agencies/pipeline-and-hazardous-materials-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/408","parent_id":492,"slug":"pipeline-and-hazardous-materials-safety-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/02/10/2026-02575.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"171","title":49},{"chapter":null,"citation_url":null,"part":"172","title":49},{"chapter":null,"citation_url":null,"part":"173","title":49},{"chapter":null,"citation_url":null,"part":"175","title":49},{"chapter":null,"citation_url":null,"part":"176","title":49},{"chapter":null,"citation_url":null,"part":"178","title":49},{"chapter":null,"citation_url":null,"part":"180","title":49}],"citation":"91 FR 5996","comment_url":null,"comments_close_on":"2026-04-13","correction_of":null,"corrections":[],"dates":"Comments must be received by April 13, 2026.
