Anthropic Was Declared a Supply-Chain Risk Twice. Contractors Are the Ones Filling Out the Forms.

A federal contracting officer opens a procurement inbox this week and finds a request that would be routine, except for the dispute behind it. The form asks the contractor to certify, on an accelerated schedule, whether Anthropic products have been identified, reported, and removed from a covered system. Two courts are still deciding whether the underlying label that triggered the form, "supply-chain risk," is even lawful.

The label is a procurement category, historically used to keep foreign adversaries' technology out of federal systems. The Department of Defense has now applied it twice to a San Francisco AI lab, and the litigation that followed has effectively turned government contractors into the enforcement arm of a fight that is far from over.

Anthropic is the company behind Claude, one of the large language models competing for federal work. The Pentagon first moved against Anthropic in early 2026, after the company refused to drop its own restrictions on Claude being used for mass domestic surveillance or fully autonomous lethal weapons. The government's response was to invoke two separate procurement statutes: a 2018 defense supply-chain statute, 10 U.S.C. § 3252, and the Federal Acquisition Supply Chain Security Act (FASCSA), a 2018 framework for broader federal procurement risk. It then issued two distinct supply-chain risk designations against Anthropic.

Anthropic challenged both designations in court. The early results have been mixed. According to reporting by the New York Times and the Associated Press, one of the two designations has been preliminarily enjoined, while the other, brought under FASCSA, remains subject to active litigation. The Pentagon is appealing at least one of the orders, per Inside Defense.

That mixed posture is now showing up inside contractors' compliance workflows. The Air Force Research Laboratory, the Air Force's main research arm, has directed contractors to identify, report, and remove Anthropic products on an accelerated schedule. Practitioners describe contractors receiving a varied set of certification and information requests, with differing scopes and certification language depending on which contracting office is asking.

The legal trade publication analysis at the National Law Review frames the situation bluntly: contractors should not assume that a preliminary injunction on one designation resolves their compliance obligations under the other. A separate Mayer Brown analysis of the FASCSA designation's effective date walks through the steps government contractors should be taking now, before the underlying legal posture is settled.

The practical pattern this week looks like this. A contracting officer receives a certification request tied to the enjoined designation and a separate removal directive tied to the live one. The contractor is being asked to attest, in writing, about the status of Anthropic products in a covered system at the same time that the legal authority for the underlying label is in active dispute. The forms require answers on a near-term schedule.

The case is tracked at the Anthropic v. Dow case explainer, which records the procedural posture. The mixed rulings mean that any contractor who acts on the assumption that the supply-chain risk label will ultimately be struck down is signing a document that may need to be reversed if the FASCSA designation is upheld. Any contractor who proceeds to remove Anthropic products on the strength of the AFRL directive is doing so while the underlying designation is in active litigation.

The legal weight of a signed certification is the part practitioners are flagging. Federal procurement certifications carry potential false-claims exposure if the underlying factual premises turn out to be wrong. With the designation's legality unsettled, "we relied on the directive" is not a complete answer.

What contractors should put in front of counsel this week, according to the legal trade analysis: which specific designation the request is tied to, whether the request originates under the enjoined 10 U.S.C. § 3252 authority or the still-active FASCSA authority, what the certification's factual predicates actually require, and what the removal directive's timeline assumes about the litigation's eventual outcome. A counsel review before signing is the conservative posture.

The Pentagon's appeal of the order removing the supply-chain risk label is the next dated milestone. Contractors signing certifications before that appeal resolves are committing to a factual position the appellate docket has not yet tested.
