Meaning
Procurement standard requiring specific alloys used in defense equipment to be melted or produced within the United States or a qualifying country. The dfars specialty metals clause is a mandatory flow-down requirement in contracts for aerospace, land systems, naval vessels and satellite communications. It protects the industrial base by ensuring that critical materials are sourced from reliable allies.
Sourcing Restriction
Contractors must verify the country of origin for every pound of titanium, stainless steel, nickel or cobalt-chromium alloy used in the production process. This dfars specialty metals requirement applies even when the metal is purchased as a sub-component from a lower-tier supplier. Failure to secure these materials from an approved source renders the entire assembly non-compliant.
Verification requires mill test reports for every batch.
Material Certification
Documentation proving the melt location must accompany the parts throughout the entire supply chain. Suppliers provide mill test reports that identify the heat number and the location of the furnace to satisfy the dfars specialty metals audit. These records are kept for the duration of the contract plus a period for government inspection.
Supply Verification
Audits of defense contractors often focus on the methods used to track these materials from the raw state to the finished part. The dfars specialty metals rules include provisions for domestic non-availability determinations when a specific material is not produced in sufficient quantities domestically.
