The FAR Council just dropped a proposed rule to enforce Section 5949 of the FY2023 NDAA, which tightens federal procurement rules around semiconductors/”>semiconductor content from certain Chinese manufacturers.
This rule goes beyond a simple use ban. It brings in a “reasonable inquiry” process for contractors, a tight 72-hour post-award reporting window, and new disclosure requirements meant to boost supply-chain transparency.
This blog unpacks what Section 5949 covers, who’s in the crosshairs, the big obligations for contractors, and some practical steps to get ready before the rule kicks in.
What Section 5949 covers and why it matters
The proposed rule turns Section 5949 into real procurement requirements. Unlike Section 889, which banned enterprise-wide use, Section 5949 Part B zeroes in on government-related critical systems and their electronic parts, products, or services that use “covered semiconductor products or services.”
The rule touches nearly all federal purchases—even micro-purchases, simplified acquisitions, and commercial off-the-shelf (COTS) goods. Covered semiconductors include products from SMIC, CXMT, YMTC, their affiliates, and any other entities the Defense or Commerce Secretaries flag as linked to “semiconductor foreign countries of concern.”
Key concepts to understand
Contractors have to do a reasonable inquiry before submitting offers to check if their products have covered semiconductors. That might mean reviewing suppliers, checking the Commerce Department’s entity list, or using supply-chain tools.
If contractors act in good faith, they can rely on supplier certifications. Offerors must certify that they’ve completed the reasonable inquiry and that they won’t provide covered semiconductors to the government. If they spot or suspect covered semiconductors after award, they’ve got just 72 hours to report it—much faster than the old 60-day limit.
Scope of applicability and what counts as a covered semiconductor
This rule stretches across almost every federal purchase and program line. It specifically calls out products from SMIC, CXMT, YMTC, and related entities, plus any others the Defense or Commerce Secretaries designate as tied to foreign countries of concern.
Suppliers now have a duty to check components from companies with possible links to restricted jurisdictions. This changes how bids get built and how supply chains are managed.
Market transparency and post-sale disclosures
The rule wants more market-wide visibility. Certain semiconductor covered entities have to disclose if their products sold to non-federal customers contain covered semiconductors.
The goal is to help the industry spot risks and possible substitutes throughout the market.
Compliance requirements for contractors
If you’re bidding on federal work, you have to conduct a reasonable inquiry to find any use of covered semiconductors. That means documenting supplier checks, cross-referencing with the Commerce entity list, and using solid supply-chain tools.
Bids need to include certifications that the inquiry was done and that covered semiconductors won’t go to the government. If you find covered semiconductors during contract performance, you have to tell the contracting officer within 72 hours.
What if a product or service contains a covered semiconductor?
If a product contains a covered semiconductor, agencies may act according to the policy’s waivers, safe harbors, or carve-outs. There’s no blanket ban on all contracts with affected suppliers, but the rule pushes for risk-based management in critical systems and related buys.
Exceptions, carve-outs, and safe harbors
The rule carves out a few exemptions: you can keep using equipment bought before December 23, 2027. There are temporary exceptions for commercial items with no alternatives until December 23, 2028.
It also includes limited carve-outs for non-IT commercial services. Agencies can grant waivers and safe harbors under strict conditions, but you’ll need to document and justify those decisions carefully.
What to expect next and how to prepare
Public comments on the proposed rule are due by April 20, 2026. For contractors, it’s time to get practical: map your supply chain, look for alternative suppliers, update compliance workflows, and gather documentation for the reasonable inquiry and post-award reporting.
Train your procurement teams, refresh bid templates, and talk with suppliers about disclosures. Staying ahead now will make life a lot easier when the rule takes effect.
Practical takeaways for procurement teams
- Initiate early supplier reviews. Bring together a cross-functional team to kick off the reasonable inquiry.
- Get ready for rapid post-award reporting (72 hours). Set up clear internal escalation paths so nobody scrambles at the last minute.
- Map the supply chain to spot potential covered semiconductors. Start exploring alternative sources—don’t wait until there’s a problem.
- Keep an eye out for waivers and carve-outs that could impact certain contracts or items. These details change quickly.
- Work with industry peers and legal counsel. Make sure you’re handling disclosures for non-federal customers the right way, if that applies.
