GSA MAS Refresh #29
GSA MAS Refresh #29: What’s Changing and How to Prepare
The General Services Administration (GSA) plans to release MAS Solicitation Refresh #29 in August 2025. This update affects both the overall MAS Solicitation and certain SINs. Once issued, contractors will have 90 days to accept the related mass modification to remain compliant.
Changes to the Overall MAS Solicitation
New Proposal Templates for FAS Catalog Platform (FCP)
The Price Proposal Template (PPT) for Products will be replaced with the FCP Product File.
The PPT for Services & Training, as well as the PPT for “541930 Translation and interpretation services” and “611630 linguistic training and education,” will be replaced with the FCP Services Plus File.
Some SINs will still require SIN-specific PPTs (including 531, 531110, 561599L, 561510, 561599, 4PL, 485, 532112, 492110, 492210, 532111, 481211O, and 481211B).
For modifications, contractors must use the same file type they used at award—either FCP templates or legacy PPTs.
Updated Electronic Commerce Clause
GSAR 552.238-103 will now clearly state that contractors must follow GSA’s established catalog requirements, with instructions available at the FCP Help Page.New Consolidated Economic Price Adjustment Clause
GSAR 552.238-120 will replace legacy clauses 552.216-70 and I-FSS-969, streamlining how price adjustments are handled. Current contracts will keep their existing EPA method until a triggering event occurs, such as an EPA or add-items modification, an option exercise, or a proposal for a new EPA method.
This clause explains how your GSA Schedule prices can increase or decrease during the life of your contract based on a pre-agreed “economic price adjustment method.” It serves as the rulebook for when and how you can request price changes and how GSA will handle those requests. The EPA method is a process you and your Contracting Officer agree to at the start of your contract, which outlines how prices will be adjusted, which prices can be changed, and any limits, timing, or frequency for those changes. EPA applies to price adjustments caused by normal market conditions—such as supplier cost increases from inflation or decreases from improved efficiencies—but does not cover adjustments required by law, executive orders, regulations, Service Contract Labor Standards, AbilityOne, the Price Reductions clause, inaccurate information you provided, or other specific contract clauses.
The method can be changed later, but only if both you and GSA agree, and the contract always takes precedence in case of a conflict. To request an adjustment, you must submit a formal request to your GSA Contracting Officer following the requirements in your EPA method and include evidence like market data or supplier invoices. The Contracting Officer will review your request, possibly conduct their own research, and decide whether to approve, partially approve, reject, or negotiate changes. Any approved changes are made through a contract modification, and if no agreement can be reached, GSA may remove the affected items from your contract. Price changes only apply to orders placed on or after the modification’s effective date, and BPAs may be adjusted separately. Once new prices are approved, you must update your GSA Advantage! and FAS Catalog Platform listings to reflect the changes.
4. Retiring All Small Business Set-Aside SINs
The last 14 retired SBSA SINs will be removed, completing the shift to non-SBSA equivalents. Order-level set-asides will still be available to encourage small business participation.
5. Updates to SCP-FSS-001 Instructions
Revisions will reflect the new EPA changes.
6. Clause and Provision Updates
Incorporates GSAR Change 187.
7. Furniture and Furnishings (C)
SIN 33712 (Complete Daycare, Preschool, and Classroom Solutions) will now explicitly exclude children’s toys, dolls, and games.
8. SIN 518210C Cloud Computing and Related IT Professional Services: SaaS offerings will no longer need to meet the “on-demand self-service” requirement from the NIST cloud definition (SP 800-145). All other NIST criteria still apply.
9. SIN 54151HACS Highly Adaptive Cybersecurity Services: Labor categories should align generally with the NICE Framework, but no longer need to reference specific “work role IDs.”
10. Removes the Awards (G01) and Personal Hair Care Items (G04) subcategories.
11. SIN 334515 will no longer include unmanned aerial/vehicle systems or drones for operations support, data collection, analysis, reporting, or related services.
12. SIN 334220 will now be the only MAS SIN covering Unmanned Aircraft Systems (UAS)/drones, in addition to surveillance systems, wearable body cameras, and vehicular video equipment. Related services such as training and installation must be part of a total solution.
13. SIN 336413 will clarify that fully assembled aircraft (rotary or fixed-wing) cannot be sold or leased under this SIN, and any special technical or regulatory requirements are the responsibility of the ordering agency.
