MAS Refresh 34 adds GSAR 552.238-130, the Federal Supply Schedule (FSS) Domestic End Product Certificate. It is voluntary: you may certify that listed products are FSS domestic end products, but nothing requires it. Certify only the SKUs you can document line by line, because the certificate is a representation to the government, not a marketing badge.
I spent eighteen years in federal acquisition as a Contracting Specialist and Contracting Officer at GSA, IRS, DoD, DOI, HHS, FTC, and Energy, holding a FAC-C Level III certification. The country-of-origin questions I saw go wrong were never about the rule itself. They were about a contractor who answered a checkbox from memory and could not produce the bill of materials when someone asked.
What is GSAR 552.238-130 and where does it come from?
GSAR 552.238-130 is a new clause created by GSA Class Deviation CD-2026-04, "Voluntary FSS Domestic End Product Certification on GSA Federal Supply Schedule." GSA's acquisition policy library lists the deviation under GSAR Part 538. Refresh 34, planned for November 6, 2026, carries the clause into the MAS solicitation and, through the mass modification, into existing contracts.
- Authority: GSA Class Deviation CD-2026-04, listed in the GSA acquisition policy library.
- Vehicle: MAS solicitation 47QSMD20R0001, Refresh 34, with the advance notice posted on the GSA Interact MAS activity feed.
- Industry webinar: Monday, October 26, 2026, 1:00 to 2:00 p.m. Eastern.
- Existing contracts: The Refresh 34 mass modification, with a 90-day acceptance window.
- Status: The advance notice says GSA is still seeking OMB clearance for the information collection tied to the certificate. Treat the draft text as subject to change until the refresh posts.
The same refresh also removes the 20-year cap on Schedule contracts, which I covered in the evergreen contract breakdown. This post is only about the domestic certificate.
What counts as an FSS domestic end product?
Based on the draft summaries of the clause, a product qualifies when three things are true: it is on your Schedule, it is manufactured in the United States, and it passes a component test. For most products, U.S.-made components must exceed 75 percent of total component cost. For iron or steel products, foreign iron and steel must be under 5 percent of component cost.
| Test | Most manufactured products | Products predominantly iron or steel |
|---|---|---|
| On your MAS contract | Required | Required |
| Where manufactured | United States | United States |
| Component test | Domestic components exceed 75% of total component cost | Foreign iron and steel under 5% of total component cost |
| Who carries the burden | The certifying contractor | The certifying contractor |
The structure mirrors the Buy American definitions in FAR 25.101, which implement 41 U.S.C. chapter 83 and the domestic content increases under Executive Order 14005. The difference is the threshold. The FAR domestic content threshold under the Buy American Act is 65 percent through calendar 2028 and rises to 75 percent in 2029. The FSS certificate, as summarized, starts at the higher figure. Confirm the final percentages in the clause text when Refresh 34 publishes.
Does this change the Trade Agreements Act rule on my Schedule?
No. MAS still carries FAR 52.225-5, Trade Agreements, and you may still sell U.S.-made or designated-country end products. The FSS certificate is an additional, optional layer. A TAA-compliant product from a designated country stays eligible for your Schedule whether or not you certify anything.
| Question | FAR 52.225-5 (Trade Agreements) | GSAR 552.238-130 (FSS Domestic Certificate) |
|---|---|---|
| Mandatory? | Yes, on every MAS contract with products | No, voluntary |
| What it decides | Whether a product may be sold at all | Whether a product may be represented as domestic |
| Acceptable origin | U.S.-made or designated country | U.S.-manufactured plus component test |
| Consequence of error | Product removal, possible termination, FCA risk | Misrepresentation, FCA risk, possible suspension |
Separately, GSA Class Deviation CD-2026-03 removes the TAA exemption that used to apply to Federal Prison Industries and AbilityOne participating nonprofit agencies. If you compete with either on the same SINs, that changes the field.
Why would a contractor certify if it is optional?
Because buyers are being pushed toward domestic products, and the certificate gives an ordering Contracting Officer a documented basis to favor yours. Under FAR 8.405, a CO choosing among Schedule quotes can weigh factors beyond price. A clean, contract-level domestic certification is easier to cite in a file than a vendor's website claim.
When I wrote best-value determinations as a Contracting Officer, the hardest thing to defend was a preference I could not trace to a document in the contract file. A website banner saying "Made in USA" never made it into my file. A representation incorporated into the vendor's Schedule contract would have.
- Agency Made in America goals: Agencies report on domestic purchasing, and program offices increasingly ask for it in requirements.
- Tie-breaking on comparable quotes: Two compliant products at similar prices, one certified domestic. The certified one is easier to justify.
- State and local buyers: Cooperative Purchasing and Disaster Purchasing buyers often have their own domestic preferences.
- Reseller positioning: Resellers of domestic manufacturers can differentiate on a vehicle where most catalogs look identical.
One caution. GSA has not said how certified products will be displayed on GSA Advantage or eBuy. Do not price or plan sales around a filter or a badge that does not exist yet.
What are the risks of certifying a product that does not qualify?
The certificate is a representation to the government. If it is false and you knew, or should have known, you face False Claims Act exposure under 31 U.S.C. 3729, which carries treble damages plus per-claim penalties, along with possible suspension or debarment under FAR 9.4. "Voluntary" describes the decision to certify, not the consequences of being wrong.
Country-of-origin cases are among the most common qui tam fact patterns in product contracting. The relator is usually a former employee or a competitor who knows where the product is actually built. As a Contracting Specialist reviewing product offers at GSA, I learned that the contractors who got burned were rarely lying. They were relying on a manufacturer's letter that was three years old and covered a different model.
- Stale supplier data: A manufacturer moves a sub-assembly offshore and nobody tells the reseller.
- SKU drift: Version 2 of a product shares a part number with version 1 but has different components.
- Cost math errors: Component cost is measured at the manufacturer's acquisition cost, not your list price. Using the wrong base inflates the domestic share.
- Blanket certifications: Certifying a whole catalog because most of it qualifies.
How do you decide which SKUs to certify?
Certify SKU by SKU, never by catalog. Start with your top sellers that you manufacture or source directly from a U.S. manufacturer, get a component cost breakdown in writing, run the test, and keep the file. Leave anything you cannot document uncertified. An uncertified product loses nothing it has today.
- Pull your last 12 months of Schedule sales from your TDR or sales reports and rank SKUs by revenue.
- Remove every SKU where the manufacturer is outside the United States. Those cannot qualify.
- For each remaining SKU, request a signed manufacturer statement covering place of manufacture and component cost by origin.
- Calculate the domestic component share against the clause threshold, using the manufacturer's component cost.
- Keep the statement, the calculation, and the date in a per-SKU file you can produce within a day.
- Set a re-verification date, at least annually and any time the manufacturer changes the product or part number.
- Certify only the SKUs that pass, and only after the final Refresh 34 clause text confirms the thresholds.
Across our 70+ GSA contract awards, the product clients who stayed out of trouble on origin questions all had the same habit: a supplier certification refreshed on a calendar, not when a problem surfaced. That habit is what makes this certificate worth signing.
What should you do before the Refresh 34 mass modification arrives?
Do the SKU analysis now, before the mass mod posts. Accepting the Refresh 34 mass modification in eMod does not certify anything by itself; the certificate is a separate, voluntary step. Accept the mod on time to protect the contract, and certify only when your documentation is ready.
- October 26: Attend the GSA webinar and note any answer on how the certificate is submitted and displayed.
- Before November 6: Finish the supplier outreach for your top 20 SKUs.
- When the refresh posts: Read the final text of 552.238-130 and confirm the thresholds and definitions.
- Within 90 days: Accept the mass modification. Missing the window puts your ability to keep selling at risk.
- After acceptance: Certify the documented SKUs and calendar the re-verification.
What Is the Bottom Line?
- GSAR 552.238-130 is a voluntary FSS Domestic End Product Certificate, created by Class Deviation CD-2026-04 and arriving with Refresh 34 in November 2026.
- As summarized, a product qualifies if it is on your Schedule, made in the United States, and over 75 percent domestic by component cost, with a 5 percent foreign iron and steel limit for steel products.
- FAR 52.225-5 and the TAA still decide what you may sell. The certificate only decides what you may call domestic.
- A false certification carries False Claims Act and debarment risk. Certify SKU by SKU with written manufacturer data.
- Accept the mass modification within 90 days whether or not you certify anything.
If you sell products on your Schedule and want a second set of eyes on which SKUs can carry the certificate, or you want the Refresh 34 mass mod handled without missing the window, our GSA Maintenance service covers mass modification acceptance and the documentation behind it.
Frequently Asked Questions
Is the GSA FSS domestic end product certification mandatory?
No. GSAR 552.238-130 permits, but does not require, MAS offerors and contractors to certify that listed products are FSS domestic end products. Products you do not certify remain on your contract under the existing Trade Agreements Act rules.
When does GSAR 552.238-130 take effect for existing MAS contracts?
It reaches existing contracts through the MAS Refresh 34 mass modification, which GSA plans to issue on November 6, 2026. Contractors have 90 days to accept the mass modification. The underlying authority is GSA Class Deviation CD-2026-04.
What is the domestic content threshold for the FSS certificate?
As summarized in the draft, a product must be manufactured in the United States with domestic components exceeding 75 percent of total component cost. For predominantly iron or steel products, foreign iron and steel must be under 5 percent of component cost. Confirm the figures in the final clause text.
Can I still sell TAA-compliant foreign products on my GSA Schedule?
Yes. MAS contracts still carry FAR 52.225-5, Trade Agreements, so products from the United States or designated countries remain eligible. The domestic certificate is an optional label for qualifying U.S. products, not a new restriction on what you may sell.
Does accepting the Refresh 34 mass modification certify my products as domestic?
No. Accepting the mass modification adds the clause to your contract, but certifying specific products is a separate, voluntary act. Accept the mod on time and certify only the SKUs you have documented.
What happens if I certify a product that is not a domestic end product?
A false certification can create liability under the False Claims Act, 31 U.S.C. 3729, including treble damages and per-claim penalties. It can also support suspension or debarment under FAR 9.4. Keep written manufacturer data for every certified SKU.
Can a reseller certify products it does not manufacture?
The certificate covers the product, not who sells it, so a reseller can certify if the manufacturer's data supports it. The reseller still signs the representation and carries the risk. Get a signed statement of place of manufacture and component cost from the manufacturer for each SKU.
