DFARS & ITAR Compliance

DFARS Compliance

Limited availability of Defense Federal Acquisition Regulation Supplement (DFARS) compliant material can make small magnet production runs costly. However, we stock various grades at our U.S. facility, enabling us to provide cost-effective, DFARS-compliant magnets for all customers if needed, regardless of project size or requirements.

ITAR Compliance

We are also registered and compliant with the International Traffic in Arms Regulations (ITAR). This qualifies us to work with items listed on the United States Munitions List (USML). We are also ITAR registered with the Directorate of Defense Trade Controls (DDTC).
