US-Japan MRA

Recognition of Certification Bodies

The Mutual Recognition Agreement between the United States and Japan (US- Japan MRA) establishes procedures for mutual acceptance of the results of conformity assessment procedures conducted by certification bodies in the U.S. and Japan within the scope of this Agreement (telecommunications terminal equipment and radio equipment).

The MRA aims to promote trade between the U.S. and Japan by reducing the cost for companies that are engaged in trade in these sectors.  

Since November 1, 2010, NIST has been accepting applications from qualified U.S. certification bodies seeking to be designated by NIST and recognized by Japan as foreign registered CABs. See the NIST Criteria for Designation to Japan (October 1, 2012 - Version 2.0) for the requirements and application instructions.
