FAR 52.225-1 Buy American—Supplies

Does the regulation require it to flow down?

No

The current text has no flow-down paragraph; primes pass it along because the domestic content test is calculated over the components YOU supply — without an origin/content certificate from the sub, the prime can't close the math on its own end product

A clause can reach your subcontract without a mandate. Once it is in your document, it is a contract term all the same. The missing mandate is a fact about the regulation. It is not a ruling on your order.

What it makes you produce

2 items for your checklist, slowest first.

  1. Something somebody else has to issue you

    The same day if the issuer is one of your own suppliers, months if it is an assessor or an underwriter.

    • Country-of-origin statements from the suppliers of those components, since the percentage rests on parts somebody else made — and the prime asking for them sets what is enough

      FAR 52.225-1

  2. Something you write

    Days to weeks, and nobody outside your company has to agree to it.

    • A component-cost table per part number, with each component's country of origin and cost, and the purchase orders and invoices behind it

      FAR 52.225-1

When it is used

Supplies contracts for delivery in the US when the Trade Agreements Act doesn't apply and no exception does (the prime delivers only domestic end products). Manufactured in the US + domestic content: 65% of component cost for 2024–2028 deliveries, 75% from 2029 on (historical baseline 60%); items predominantly of iron/steel: less than 5% foreign iron/steel in component cost. COTS gets the component test waived (except the iron/steel rule).

Read closely

(d) is the delivery restriction and it reads on what was specified in the Buy American Certificate; the clause names neither the table nor a supplier statement. The bar is 65 percent of component cost for deliveries through 2028 and 75 percent from 2029, so a multi-year program has a transition inside it. For an item wholly or predominantly of iron or steel the test changes to a foreign share under 5 percent.

This is research, not legal advice. It states what the regulation says about this clause and cites the paragraph behind it. It does not rule on your order, and it does not rule on whether a prime's markings are correct.
