January 1 Is Already in Your Contract: The Covered-Materials Collision
Most compliance deadlines need an agency to act: a proposed rule, a comment period, a final rule with a compliance date in the preamble. The covered-materials deadline is not that kind of deadline. It has been sitting, self-executing, in signed DoD contracts since 2024. DFARS clause 252.225-7052, "Restriction on Acquisition of Certain Magnets, Tantalum, and Tungsten" (MAY 2024), is prescribed for essentially every DoD contract above the simplified acquisition threshold (generally $250,000), expressly including commercial-product and commercial-service acquisitions under FAR part 12. And it goes in whether or not the deliverable contains a covered material. The discriminating work happens at the exception level. In solicitations issued under the 2026 class deviation, the restriction rides in narrower form as deviation clause 252.225-7961. The upstream limb, material mined, refined or separated in a covered country, attaches only to contracts awarded on or after January 1, 2027, and the melted-or-produced limb carries no sunset date.
Here is what the clause does on its own, with no further action from anyone. Through December 31, 2026, the contractor may not deliver covered material melted or produced in a covered country, nor any end item manufactured in a covered country that contains one. Then the text steps up by its own terms. "Effective January 1, 2027, the Contractor shall not deliver under this contract any covered material mined, refined, separated, melted, or produced in any covered country, or any end item, manufactured in any covered country, that contains a covered material." Same contract, same signature. On New Year's Day the compliance question moves from the furnace to the mine.
Covered material means samarium-cobalt magnets, neodymium-iron-boron magnets, tantalum metals and alloys, tungsten metal powder, and tungsten heavy alloy or any finished or semi-finished component containing it. Covered country means North Korea, China, Russia, and Iran. And the clause itself states the January reach per material. For a samarium-cobalt magnet, the restriction runs "the entire supply chain from mining or production of a cobalt and samarium ore or feedstock, including recycled material, through production of finished magnets." The contract text itself calls for mine-level origin proof.
One date, four instruments
Four independent instruments converge on January 1, 2027. Each closes an exit the others leave open.
The clause restricts deliveries. Every contract already carrying the MAY 2024 clause restricts what the contractor may deliver beginning January 1, 2027. The escalation quoted above is contract text already in force.
The statute restricts awards at every tier. 10 U.S.C. 4872 bars contract awards on or after January 1, 2027 for covered material mined, refined, or separated in a covered nation, and its own terms apply the restriction to "prime contracts and subcontracts at any tier." The two legs attach differently. Existing contracts containing the MAY 2024 clause restrict deliveries beginning January 1, 2027; every new award on or after January 1, 2027 carries the upstream restriction from day one.
The executive order closes the waiver door. Under Executive Order 14415 (July 20, 2026), on January 1, 2027 the Department ceases to issue covered-materials waivers except against a formal mitigation plan, accepted by the Secretary or his designee, that identifies the noncompliant source; documents "exhaustive efforts" to acquire compliant material, or demonstrates that compliant material was unavailable at the time of acquisition; describes the steps that will remove the material from the supply chain; and establishes a "strict projected timeline" for finishing the job. The order fences the national-security waiver route as well. Failure to qualify a domestic source does not count as nonavailability unless the contractor can show "active, adequately funded, and ongoing efforts" to qualify one, and failure to qualify an alternative source is grounds to decline options and terminate. By statute, a covered-materials waiver under 10 U.S.C. 4872(c)(1) is limited to a specific end item and a specific covered material, for a maximum of 36 months.
The recapture closes the electronics loophole for SmCo. The clause excepts end items that are electronic devices. That exception is easy to read as shelter for anything with a circuit board. It is not. A samarium-cobalt magnet inside an electronic device remains restricted under the specialty-metals statute, 10 U.S.C. 4863, because the clause that implements it, DFARS 252.225-7009, defines "electronic component" to exclude "any high performance magnets that may be used in the electronic component". DoD itself codifies that reading at PGI 225.7018-3. In traveling-wave tubes, isolators, circulators, and RF assemblies, the SmCo inside stays in the restricted population no matter how the end item is classified.
The waiver record
Contractors planning to ride a waiver through 2027 should first look at the closest record on the books. The specialty-metals rule has offered a national-security waiver since its 2009 final rule. Those waivers are requested by a DoD component rather than filed by the contractor. Each requires congressional notification. When GAO last examined the record, six had been approved since the 2009 final rule, five of them for samarium-cobalt magnets. Against a record that sparse, no compliance strategy should run its critical path through waiver relief. The instrument the executive order actually leaves open is the mitigation plan. That document is the contractor's own artifact, accepted or rejected on the evidence inside it. The fastest way to fail one is to assert "exhaustive efforts" rather than prove them.
Where the materials hide
The reflex is to hear "magnets, tantalum, tungsten" and picture exotic hardware. The materials are more ordinary than that.
Neodymium-iron-boron magnets sit in nearly everything that moves under electric power: flight-control and missile actuation, servo motors, gimbals, generators, drone and UUV propulsion. Samarium-cobalt magnets live where heat and stability rule them in: traveling-wave tubes, isolators and circulators, high-temperature motors and sensors. As above, they carry their restriction into electronic devices with them. Tungsten heavy alloy (the ASTM B777 class, roughly ninety percent tungsten and up) is penetrators, fragmentation, counterweights, and vibration-damping mass. Tungsten metal powder is the same problem one tier down, at the feedstock level. Tantalum is the misdirection. The famous application is capacitors, but capacitor-bearing board electronics generally exit as electronic devices. The tantalum that stays restricted lives in superalloy turbine hot sections, mill products, sputtering targets delivered as such, and energetics.
The list is also not finished. Molybdenum has been a covered material at the statutory level since December 2025. The clause has not yet caught up, so molybdenum is restricted by statute now, with clause implementation pending. And gallium and germanium join the restriction on December 18, 2027. That is enacted law with a delayed effective date. GaN and GaAs RF chains and germanium thermal-imaging optics are the second wave, arriving twelve months behind the first.
The flowdown, precisely
Flowdown is where this clause is most often misquoted, in both directions. Insertion at the prime level requires a contract above the simplified acquisition threshold, commercial acquisitions included. The flowdown itself has no dollar threshold. What limits it is content. The contractor must insert the substance of the clause in subcontracts and other contractual instruments "for items containing a covered material," commercial products included. A $40,000 purchase order for a gimbal assembly with NdFeB motors carries the clause; a $4 million subcontract for items containing no covered material does not. And beneath the contract paper, the statute reaches prime contracts and subcontracts at any tier. In practice, machine shops and component houses that have never read a prime contract will meet this clause in their purchase-order terms, attached to deliveries dated after January 1.
The exceptions narrow on the same date. Acquisitions at or below the simplified acquisition threshold are out. COTS end items are out, but on January 1, 2027 the COTS carve-back widens from items that are 50 percent or more tungsten by weight to items 50 percent or more covered material by weight, and the mill-product recapture broadens from tantalum and tungsten products to every covered material. The electronic-device exception shelters device end items. It does not reach the actuator mounted next to one, and it never reaches the SmCo inside one. Recycled NdFeB escapes if the milling and sintering happen in the United States. At the statutory level, where the clause has not yet caught up, recycled SmCo gets the same treatment, and recycled tantalum, tungsten, and molybdenum qualify only if the contractor "demonstrates to the Secretary" where the material came from and where it was processed. Read as a category, every exception on that list is a documentary determination. None is self-executing. Each one you rely on is a claim you will eventually be asked to support.
What the time remaining is for
Between now and January 1, the work is three evidence files. The origin file: for each covered material in each deliverable, the chain from ore or feedstock, including recycled feedstock, through finished component, documented at the level the clause now names. The exceptions map: which deliverables genuinely shelter under SAT, COTS, electronic-device, or recycled-feedstock treatment, with the January 1 narrowings and the SmCo recapture applied. The mitigation plan, for the gaps: an evidence package built to the executive order's four elements, with the noncompliant source identified, a sourcing record that proves exhaustive efforts rather than asserting them, and a funded qualification effort standing behind the timeline. That is the only version the order leaves room for.
Gatewell Defense, the covered-materials practice of Gatewell Group, builds exactly these files. A two-week, fixed-fee diagnostic screens your bill of materials against the full covered-materials list (the clause's five, the statute's additions, and the exceptions that actually apply). It flags the double-coverage traps and locates your January 1 exposure precisely, with every finding traced to primary text: the clause, the statute, and the executive order. The date is already in your contract.
