DFARS and Domestic Metals: A Complete Guide for Defense Contractors

What the Specialty Metals Clause Requires

DFARS 252.225-7014, the Preference for Domestic Specialty Metals clause, requires that specialty metals incorporated in items delivered under a DoD contract be melted or produced in the United States or a qualifying country. The clause applies to prime contracts and flows down to subcontracts at all tiers for items that will be incorporated into deliverables. It is not a preference or a best-effort requirement - it is a mandatory compliance obligation with specific documentation and traceability requirements.

Which Metals Are Covered

Specialty metals under DFARS 252.225-7014 include: steel with more than certain alloy content thresholds; titanium and titanium alloys; zirconium; niobium; tungsten; molybdenum; tantalum; and aluminum alloys. The inclusion of aluminum alloys is not always intuitive to buyers accustomed to thinking of DFARS as primarily a titanium and steel issue. Any aluminum alloy - 6061, 7075, 7050, 5083, or otherwise - incorporated into a DFARS-covered deliverable must meet the origin requirements.

The Qualifying Country List

DFARS 252.225-7003 lists the qualifying countries whose aluminum satisfies the DFARS domestic preference when the specialty metals are both melted and manufactured within those countries. As of the current regulation, the list includes: Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Israel, Italy, Japan, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, South Korea, Spain, Sweden, Turkey, and the United Kingdom. Material from non-listed countries - including China, Russia, India, and most of South America - does not qualify regardless of how it enters the US supply chain.

Melt AND Manufacture: Why Both Matter

The DFARS requirement is conjunctive: the specialty metal must be both melted and manufactured in the US or a qualifying country. Buying aluminum from a domestic service center or distributor does not automatically satisfy DFARS if the billet was melted offshore. A domestic fabricator who purchases Chinese-melt billet and extrudes or rolls it in the US has met the manufacture requirement but not the melt requirement - the resulting product does not comply. This is one of the most common misunderstandings in DFARS aluminum procurement. The traceability chain must extend back to the melting furnace.

What the Mill Certificate Must Show

For DFARS compliance, the material test report (mill certificate) must explicitly state the country where the metal was melted. A cert that identifies the producing mill by name but does not state country of origin is insufficient for DFARS documentation. The heat number on the cert must be traceable to a specific melt at a specific facility in a qualifying country. When requesting DFARS material from a supplier, specify that the cert must include country of origin and that you require full heat number traceability. Accepting delivery without verifying the cert creates compliance exposure that cannot be retroactively resolved after the part has been shipped to the prime.

Common Compliance Failures

• Buying from a domestic distributor who sources opportunistically and cannot guarantee qualifying-country melt for all lots
• Missing or incomplete country of origin on the mill certificate
• Failure to flow down the DFARS clause to sub-tier suppliers
• Mixing DFARS and non-DFARS material in the same lot without segregation and documentation
• Accepting scanned third-generation cert copies that are not traceable to an original mill document
• Using any-origin material purchased before DFARS requirements were established and certifying it as compliant after the fact

Domestic Content Thresholds Are Rising

DFARS 252.225-7001 Buy American and Balance of Payments Program requires that the cost of domestic and qualifying country components exceed a specified percentage of total component costs. For contracts with deliveries between 2024 and 2028, that threshold is 65%. Starting in 2029, the threshold rises to 75%. Programs with long production runs that span this threshold change should plan for the higher requirement now rather than facing a mid-program sourcing transition.

How Section 232 Changed the Cost Math

The February 2025 restoration of 25% Section 232 tariffs on all aluminum imports - with no country exemptions - changed the landed cost comparison between DFARS-compliant domestic material and any-origin material. Prior to the tariff reset, any-origin aluminum from offshore mills sometimes arrived at prices 15 to 25% below domestic. The 25% import tariff eliminates most of that cost advantage and in some cases inverts it, making domestic-melt material competitive or cheaper on an all-in basis. For programs already obligated to DFARS compliance, this is a favorable development. For buyers on commercial programs evaluating whether to source domestically, the tariff environment makes the decision more straightforward.
