The China Compliance Wall Is Up: New DoD Prohibitions Every Defense Contractor Must Understand

As of June 30, 2026, the Department of Defense is prohibited from entering into, renewing, or extending contracts with companies designated as Chinese military companies on its Section 1260H list, along with their subsidiaries and affiliates. A companion prohibition bars DoD from contracting with any company whose consultants lobby for those listed entities. And the hardest part is still ahead: in June 2027, the restriction extends down through the entire supply chain. Here is what took effect, what is coming, and what to do about it.

What Took Effect on June 30

The direct entity ban. Section 805 of the FY2024 NDAA prohibits DoD from procuring goods, services, or technology directly from entities on the 1260H list — the Pentagon’s annually published roster of companies determined to be Chinese military companies operating in the United States, which spans sectors including AI, aerospace, and biotechnology and has grown to well over a hundred parent companies and subsidiaries.

The lobbyist ban. Section 851 of the FY2025 NDAA prohibits DoD from contracting with any company whose consultants engage in lobbying activities for a 1260H-listed company. The reach is deliberately broad: the disqualifying lobbying does not have to relate to your contract, your industry, or defense work at all. A marketing consultant or government-relations advisor on your vendor list that separately lobbies for a listed Chinese company can disqualify your entire organization from DoD awards.

The implementing rules. DoD issued a class deviation creating a new Subpart 240.70 on prohibited sources and a new clause, DFARS 252.240-7995. Notably, an offeror represents its compliance simply by submitting a proposal — no separate signed certification required. Submitting a bid is the representation.

The 2027 Cliff: Supply Chains Come Next

On June 30, 2027, the “goods and services prohibition” arrives: DoD will be barred from acquiring products or services that include inputs sourced — even indirectly — from listed companies or entities they control. Every defense contractor must map its supply chain and eliminate 1260H-linked inputs. DoD has publicly warned contractors not to wait until 2027 to start, because a last-minute waiver request will be a painful process.

A Compliance Roadmap for Small Contractors

1. Pull the current 1260H list and screen your relationships. Check direct suppliers, teaming partners, technology vendors, and — critically — any consultants or advisory firms you retain. The statute includes a safe harbor for companies that make “reasonable inquiries” into their contractors’ lobbying activities and reasonably conclude they are not covered lobbyists. That safe harbor only protects firms that actually made the inquiry and documented it.

2. Add representations to your consultant and vendor agreements. Require current and prospective consultants to represent and warrant that they do not, and will not, engage in lobbying activities for 1260H-listed companies. Build the same screening into onboarding for new vendors.

3. Start the supply chain map now. Inventory where your products, software, and service inputs originate, flag anything with a plausible link to listed entities, and identify alternative sources while you still have negotiating time.

4. Treat compliance as a competitive asset. Primes carry these obligations too, and they flow the risk down. A small business that can demonstrate documented 1260H screening, clean supplier representations, and a mapped supply chain is a safer teaming partner — and safer partners win subcontracts.

The Bottom Line

Congress has spent five years building a wall between the U.S. defense industrial base and China’s, and June 30 was the day the first full section went up. For small businesses, the burden is real but manageable — screen the list, paper your vendor relationships, document your inquiries, and start the supply chain work a year before the 2027 deadline makes it urgent. With defense budgets growing while the compliant vendor pool shrinks, the math favors firms that do this work early. Brick by brick.

Frequently Asked Questions

What is the Section 1260H list?

The Pentagon’s annually published roster of companies determined to be “Chinese military companies” operating in the United States, named for the section of the FY2021 NDAA that requires it. It spans sectors including AI, aerospace, and biotechnology, and covers well over a hundred parent companies and subsidiaries.

What DoD prohibitions took effect on June 30, 2026?

Two: a direct ban on DoD entering, renewing, or extending contracts with 1260H-listed companies (Section 805, FY2024 NDAA), and a ban on DoD contracting with any company whose consultants engage in lobbying for listed entities (Section 851, FY2025 NDAA). Under the implementing DFARS class deviation, submitting a proposal itself constitutes the compliance representation.

What happens in June 2027?

The prohibition extends through the supply chain: DoD will be barred from acquiring products or services that include inputs sourced — even indirectly — from listed companies or entities they control. Every defense contractor needs a mapped, documented supply chain free of 1260H-linked inputs.
