DoD
Specialty Metal Certifications

Fastener Manufacturers providing fasteners to customers under contracts that contain Department of Defense Federal Acquisition Requirements (DFARS) clauses that require compliance with domestic specialty metals purchasing requirements (usually listed as DFARS 225.700 with a number following the “700”) can provide DFARS compliant fasteners in one of several ways according to 10 USC 2533b.  One of the provisions of 10 USC 2533b and the DFARS allows fastener manufacturers to certify that its commercial fasteners are DFARS compliant under the following conditions:

“Acquisitions of fasteners that are commercial items that are purchased under a contract or subcontract with a manufacturer of such fasteners, if the manufacturer has certified that it will purchase, during the relevant calendar year, an amount of domestically melted specialty metal, in the required form, for use in the production of fasteners for sale to the Department of Defense and other customers, that is not less than 50% of the total amount of the specialty metal that it will purchase to carry out the production of such fasteners for all customers. [10 USC 2533b(h)(3)]”

Please click the link for the appropriate year to see fastener manufacturers providing certifications to their customers (for that calendar year) that they purchase not less than 50% of their specialty metals from domestic sources.  Interested parties should contact the manufacturers directly for further information.
