The Special Permits search tool is being upgraded to improve its functionality. This should not affect your basic search function; however, please contact PHMSAWebmaster@dot.gov if you experience any issues.

The provided special permits are official copies of every current document (with date and signature) and, due to numerous inquiries, several expired special permits.

Note: All rulemakings, regulations and notices issued prior to February 15, 2005 refer to the previous Research and Special Programs Administration (RSPA). Although RSPA is no longer an operating DOT agency, all rulemakings, regulations and notices issued by the agency continue to be valid.

Under HM-215N ‘Hazardous Materials: Harmonization with International Standards,’ PHMSA authorized the use of Transport Canada’s Equivalency Certificates in the United States.  This authorization only applies until the shipment’s initial destination. You can search Equivalency Certificates here by company name or file number.
