What Can't You Sell on a GSA Schedule in 2026? Out-of-Scope Items Explained

You cannot sell construction, architect-engineer (A/E) services, firearms and ammunition, non-TAA-compliant products, most drones, or anything on GSA's "General Out of Scope Items" list on a GSA Multiple Award Schedule (MAS) contract in 2026. Offerings that conflict with several 2025 executive orders are also excluded. Propose any of them and expect a rejection or a catalog flag.

I spent 18 years in federal acquisition as a Contracting Specialist and Contracting Officer at GSA, IRS, DoD, DOI, HHS, FTC, and Energy. Scope is the first gate a GSA reviewer checks, and it has moved more since March 2025 than in the prior decade.

What can't you sell on a GSA Schedule in 2026?

MAS exclusions fall into three buckets: statutory or jurisdictional limits that never fit the Schedule model, items GSA removed through its 2025 "rightsizing" of the program, and offerings excluded by executive order. The source matters, because it tells you how likely the exclusion is to change.

Why are construction and A/E services outside the GSA Schedule?

Construction runs under FAR Part 36 and prevailing-wage rules, and A/E services must be bought through the Brooks Act's qualifications-first selection. Neither fits a Schedule built on pre-negotiated commercial pricing and order-level price competition. GSA now writes that boundary directly into SIN descriptions.

• SIN 541620 Environmental Consulting: Refresh 32 added a note that services "cannot include architect-engineer services as defined in the Brooks Act and FAR Part 2, or construction services as defined in FAR Parts 2 and 36," citing GSA Class Deviation RFO-2025-36. I cover what that means for environmental firms in the Refresh 32 changes post.
• What is still in bounds: installation and site preparation tied to Schedule products (SIN 238910), and roofing repair or replacement under SIN 238160. The Refresh 33 draft says standalone roofing services are within scope.
• The test a CO applies: is the work the construction, alteration, or repair of real property, or professional design that requires a licensed architect or engineer? If yes, it does not belong on your price list.

Which products are on GSA's "General Out of Scope Items" list?

Every Large Category attachment now carries the same statement: GSA will not award items in these categories. The list started with four items in Refresh 26 (April 2025), grew in Refresh 27, and was expanded again in Refresh 31.

• Remanufactured, refurbished, reconditioned, remarketed, and repaired items (remanufactured toner is the exception)
• Automotive parts and personal hygiene items
• Fully assembled fixed-wing aircraft
• Books and publications (except technical publications and reports on SIN 511120)
• Children's toys, dolls, and games; promotional products; sporting goods
• General clothing (except workwear on SIN 3152, uniforms on SIN 315210, and protective apparel on SIN 339113PA)
• Swimming pool equipment, musical instruments, customizable awards, medals and ribbons
• Live animals used for laboratory research and testing
• Food, candy, and drinks

Food deserves a note. Refresh 31 carved out non-perishable food under SIN 311423, then closed that SIN to new offers, and Refresh 32 retired it. The Refresh 33 draft confirms food and beverages "remain out of scope," with two narrow exceptions: bottled water under the 4PL SIN, and meals only as part of a total turnkey base camp solution under SIN 532490P.

How did GSA's rightsizing initiative shrink the Schedule?

On March 24, 2025, GSA announced it would rightsize MAS by letting low-sales contracts expire, addressing non-compliance, cutting redundancy with other channels, and eliminating items with insufficient demand. The item cuts came through SIN retirements, and much of what those SINs held landed on the out-of-scope list.

GSA's rightsizing announcement framed this as putting resources where federal buyers actually spend. A retired SIN cannot be proposed, and a mod citing it will come back.

Which executive orders take offerings out of MAS scope?

Starting with Refresh 25 in March 2025, GSA added executive-order advisories to each Large Category attachment. Any product, service, or solution that violates the cited order provisions is excluded from the MAS program, regardless of which SIN it is proposed under.

The statutory-basis language is where firms get tripped up. An environmental or energy service required by statute can stay in scope; the same service marketed around a revoked policy cannot. The separate DEI contract clause that arrived with Refresh 32 under E.O. 14398 is a compliance obligation, not a scope list, and I break it down in the Refresh 32 preview and the Refresh 32 changes post. The original advisories are in GSA's Refresh 25 Interact notice.

What about drones, firearms, TAA, and end-of-support products?

These four sit outside the general list but stop offers just as often. Drones are limited to the Blue UAS Cleared List, firearms and their components are fully excluded, every product must be TAA-compliant, and a CO may refuse obsolete technology outright.

• Drones: GSA will not award unmanned aircraft systems, as defined in 49 U.S.C. Chapter 448, unless they are on the Blue UAS Cleared List. Refresh 32 updated the language because the program moved from DoD's Defense Innovation Unit to DCMA's Special Programs Unmanned Systems-Experimental (US-X) office. Older guides still point to DIU.
• Firearms and ammunition: excluded in every Large Category, and Refresh 31 explicitly added foreign replica weapons and inert ordnance.
• Trade Agreements Act: products must be U.S.-made or substantially transformed in a TAA-designated country under FAR Subpart 25.4. GSA Class Deviation CD-2026-03 (August 14, 2026) removed the exception AbilityOne and Federal Prison Industries had, and the Refresh 33 draft applies it.
• End-of-Support items: since Refresh 32, a CO may request supply and support data when a product's EOS date is three years or less from the offer, and may decline to award obsolete items. Details are in the Refresh 32 preview.

Why do out-of-scope items cause offer rejections and catalog flags?

A CO cannot award what the solicitation excludes, so one out-of-scope line item can stall an entire offer or modification. On existing contracts, the FAS Catalog Platform (FCP) and GSA's catalog reviews surface excluded items, and the CO will direct you to remove them.

When I sat on the other side of the desk as a Contracting Officer, scope was the fastest call to make and the most common reason a product mod came back. The usual cause was a reseller uploading a full distributor feed, with a handful of excluded items buried among compliant ones. From the Contracting Specialist seat, the review does not skip those items. It stops on them.

1. Bulk catalog uploads: distributor feeds routinely include refurbished stock, apparel, sporting goods, or automotive parts.
2. Legacy awards: items awarded before 2025 on a SIN that has since been retired.
3. Service descriptions that drift: LCATs that read like design or construction work.
4. Country of origin changes: a manufacturer moves production to a non-designated country mid-contract.

Across our 70+ GSA contract awards, the offers that moved cleanly were the ones where every line item mapped to a live SIN and nothing needed defending. If your catalog was flagged, here is how to remove flagged products in FCP.

How do you audit your offer or contract for scope?

Run a line-by-line scope check against the current Large Category attachment before every offer, add-SIN mod, and catalog update. Read the "General Information" section first, then the SIN description and notes.

1. Download the current Large Category attachment for each category you hold.
2. Compare every product against the General Out of Scope list and the drone, firearms, and EO advisories.
3. Confirm each SIN on your contract still exists after Refreshes 26, 27, and 32.
4. Re-verify country of origin for every product, including AbilityOne and FPI items.
5. Reread service and LCAT descriptions for A/E, construction, or revoked-policy language.
6. Remove or correct flagged items before GSA asks, and document why each remaining exception applies.

What should you do now?

• Pull the current attachments. The out-of-scope list changes with refreshes, and the Refresh 33 notice was updated September 24, 2026.
• Scrub your catalog for remanufactured, apparel, automotive, food, toy, and sporting goods items that predate the 2025 list.
• Check exceptions by SIN. Toner, technical publications, workwear, uniforms, and protective apparel are allowed only on their named SINs.
• Keep A/E and construction off MAS. Route that work through the right vehicle instead of reshaping a service description.
• Watch Interact. Follow GSA's MAS refresh notices and read what is coming in Refresh 33.

I hold FAC-C Level III and a Harvard Master of Liberal Arts, and I have reviewed scope from both sides of the table. If you are not sure whether your products or services fit a live SIN, talk to Blackfyre about a scope review before you submit your GSA Schedule offer so the first thing a CO sees is a clean, awardable price list.

Frequently Asked Questions

Can you sell construction services on a GSA Schedule?

No. Construction falls under FAR Part 36 and prevailing-wage requirements, which do not fit the MAS pricing model. Limited installation and site preparation tied to Schedule products, and roofing repair or replacement under SIN 238160, remain in scope.

Are architect-engineer services allowed on GSA MAS?

No. A/E services covered by the Brooks Act must be bought through qualifications-based selection, not the Schedule's pre-negotiated pricing. Refresh 32 wrote that exclusion directly into SIN 541620 Environmental Consulting.

Can I sell refurbished or remanufactured products on GSA Advantage?

No, with one exception. GSA's General Out of Scope list excludes remanufactured, refurbished, reconditioned, remarketed, and repaired items, except remanufactured toner.

Can you sell food or drinks on a GSA Schedule in 2026?

Generally no. SIN 311423 Non Perishable Foods was retired in Refresh 32, and the Refresh 33 draft confirms food and beverages remain out of scope. The draft allows bottled water under the 4PL SIN and meals only within a turnkey base camp solution under SIN 532490P.

Can drones be sold on a GSA Schedule?

Only drones on the Blue UAS Cleared List. Refresh 32 updated the language to reflect that the list is now managed by DCMA's Special Programs Unmanned Systems-Experimental (US-X) office rather than DoD's Defense Innovation Unit.

What happens if my GSA contract has out-of-scope items on it?

The CO can direct you to remove them, and a pending mod or offer that includes them can be rejected or returned. The fix is to remove the items through FCP or eMod before GSA flags them.

Why did GSA retire so many SINs?

GSA's March 2025 rightsizing initiative targeted items with insufficient market demand or where administrative costs outweighed procurement benefits. Refresh 26 retired 32 SINs, Refresh 27 retired 10, and Refresh 32 retired SIN 311423.
