When does DFARS 252.225-7008 apply?

Does the contract acquire end items in one of the covered categories (aircraft, missile/space, ships, tank/automotive, weapons, ammunition) or components for them? If yes, the specialty-metals restriction generally applies. Pure commercial-product DoD purchases that fall outside the listed categories are typically not in scope. Is the item a COTS item under FAR 2.101? COTS items (other than specialty metals themselves and certain electronic components) are statutorily exempt under 10 U.S.C. 4863(g). The COTS determination must be defensible. A modified-COTS item may not qualify. Is the specialty-metal content de minimis under the clause definitions? There is a small de minimis exception. Confirm against the current clause text and document the calculation. De minimis is not a free pass; it is a tightly defined exception.

What are the most common contractor pitfalls under DFARS 252.225-7008?

Missing mill certifications at lower tiers: Specialty-metals compliance requires traceability to the melt source. Sub-tier suppliers that cannot produce melt certifications expose the prime to non-compliance. False Claims Act cases in aerospace fasteners have repeatedly originated in this gap. Assuming COTS without analyzing modifications: A standard catalog part used as-is may be COTS. The same part with a DoD-specific modification, plating, or coating may not be. The COTS determination must look at the specific configuration delivered, not the supplier's catalog description. Confusing qualifying-country specialty metal with qualifying-country end product: The specialty-metals test is on the melt source for the metal, not the country where the finished article was assembled. A finished part assembled in a qualifying country can still fail if the underlying specialty metal was melted elsewhere. Treating waivers as permanent: Domestic Non-Availability Determinations (DNADs) and other waivers are typically item-and-period specific. They do not survive a sourcing change or expire automatically. Re-validate at each procurement action.

What audit-flag patterns are associated with DFARS 252.225-7008?

Auditors and contracting officers commonly flag: Component delivery records with no mill certification or with mill certifications from non-qualifying countries; Pattern of COTS claims on items that were modified for the DoD application; Specialty-metal sourcing changes without a documented re-analysis; Discrepancies between the supplier's certification and the underlying mill cert origin; DNADs cited beyond their stated period or scope.

DFARS 252.225-7008 — Restriction on Acquisition of Specialty Metals

Implements 10 U.S.C. 4863 (formerly 10 U.S.C. 2533b) to require that specialty metals incorporated into certain DoD end items be melted or produced in the United States or in a qualifying country, with limited exceptions.

What this clause does

DFARS 252.225-7008 (and the closely related 252.225-7009) is the operational implementation of the specialty-metals statute. The statute restricts DoD from acquiring specified categories of end items, components, and materials unless any specialty metal contained in them was melted or produced in the United States or in a qualifying country. Specialty metals include certain steels, nickel- and cobalt-base alloys, titanium and titanium alloys, and zirconium and zirconium-base alloys, with the precise list defined in the clause definitions.

The rule applies most directly to DoD acquisitions of aircraft, missile and space systems, ships, tank and automotive items, weapons systems, and ammunition, plus certain components incorporated into those items. The flowdown reaches into the supply chain: a sub-tier supplier providing a fastener that contains specialty metal must meet the same melt-or-produce test. There are statutory exceptions, including the COTS exception under 10 U.S.C. 4863(g), the de minimis exception, certain electronic component exceptions, and DPAS-prioritized exceptions for non-availability.

Compliance evidence almost always lives several tiers below the prime. Mill certs, melt certifications, and chain-of-custody documentation must trace the metal back to a domestic or qualifying-country melter. False or missing certifications have driven multiple Department of Justice settlements under the False Claims Act, particularly in aerospace fastener and forging supply chains.

Does this clause apply to my contract?

Three tests resolve applicability. Read each in order; the first "no" usually means the clause does not flow.

1.Does the contract acquire end items in one of the covered categories (aircraft, missile/space, ships, tank/automotive, weapons, ammunition) or components for them?
If yes, the specialty-metals restriction generally applies. Pure commercial-product DoD purchases that fall outside the listed categories are typically not in scope.
2.Is the item a COTS item under FAR 2.101?
COTS items (other than specialty metals themselves and certain electronic components) are statutorily exempt under 10 U.S.C. 4863(g). The COTS determination must be defensible. A modified-COTS item may not qualify.
3.Is the specialty-metal content de minimis under the clause definitions?
There is a small de minimis exception. Confirm against the current clause text and document the calculation. De minimis is not a free pass; it is a tightly defined exception.

Common contractor pitfalls

Patterns that produce questioned costs, back-wage liability, or False Claims Act exposure under this clause.

Missing mill certifications at lower tiers
Specialty-metals compliance requires traceability to the melt source. Sub-tier suppliers that cannot produce melt certifications expose the prime to non-compliance. False Claims Act cases in aerospace fasteners have repeatedly originated in this gap.
Assuming COTS without analyzing modifications
A standard catalog part used as-is may be COTS. The same part with a DoD-specific modification, plating, or coating may not be. The COTS determination must look at the specific configuration delivered, not the supplier's catalog description.
Confusing qualifying-country specialty metal with qualifying-country end product
The specialty-metals test is on the melt source for the metal, not the country where the finished article was assembled. A finished part assembled in a qualifying country can still fail if the underlying specialty metal was melted elsewhere.
Treating waivers as permanent
Domestic Non-Availability Determinations (DNADs) and other waivers are typically item-and-period specific. They do not survive a sourcing change or expire automatically. Re-validate at each procurement action.

Audit-flag patterns

Specific signals that contracting officers, DCAA, and agency IGs use to surface noncompliance.

Component delivery records with no mill certification or with mill certifications from non-qualifying countries
Pattern of COTS claims on items that were modified for the DoD application
Specialty-metal sourcing changes without a documented re-analysis
Discrepancies between the supplier's certification and the underlying mill cert origin
DNADs cited beyond their stated period or scope
