DFARS & ITAR 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.
