Major Takeaways from MAS Refresh #26: What It Means for Current GSA Schedule Holders
The U.S. General Services Administration (GSA) is preparing to issue MAS Solicitation Refresh #26 by the end of April 2025. This update represents one of the most significant shifts in the MAS program in recent years, focusing on streamlining offerings, updating templates and clauses, and refining the scope of products and services available through Schedule contracts.
1. Retirement of 32 SINs – Some Contractors Will Lose Their Only SIN and their contract will be cancelled.
GSA is retiring 32 Special Item Numbers (SINs) across several MAS categories, including Office Management, Furniture, Professional Services, and Transportation. If a MAS contract includes only a SIN that is being retired, GSA will cancel the entire contract under clause 552.238-79. There will be no automatic opportunity to add a new SIN beforehand to keep the contract alive.
Impacted contractors must take action now to:
Identify alternative SINs (if available) to migrate products or services.
Prepare to update price lists and catalogs in SIP or FCP once the mass modification is issued.
GSA has outlined alternative procurement channels for each retired SIN, such as other MAS SINs or the open market.
2. Mandatory Acceptance of the Mass Modification
Every MAS contractor must accept the Mass Mod for Refresh 26 once it is issued. If you don’t accept it by the deadline set in eMod, your contract will be considered non-compliant with the latest MAS Solicitation terms.
The Refresh will also automatically:
Remove retired SINs.
Trigger a follow-up mod to delete associated products/services.
Require contractors to update their electronic pricelists.
3. Subcategory Realignments and New Categories
GSA is continuing its efforts to refine and optimize how services are organized. Two new subcategories have been created:
Cloud Services (F01): SIN 518210C is being moved here and now includes AI/ML cloud services explicitly.
Financial Management Services (F03): SIN 518210FM is relocated from the IT Subcategory to this newly formed category.
If your company provides services in either of these areas, it’s time to revisit your categorization and update your offerings accordingly.
4. Program Evaluation Subgroup Under SIN 541611
A major new subgroup under SIN 541611 has been introduced: Program Evaluation Services. This subgroup is designed for vendors offering data-driven assessments of federal programs and policies.
Adding this subgroup requires:
A 3-page technical narrative,
3 project experience examples, and
A scenario response, all evaluated by a Technical Evaluation Board from multiple federal agencies.
Vendors who fail must wait 6 months (or 1 year for second failures) to reapply. This adds a layer of specialization to SIN 541611 and will help federal buyers find more targeted expertise.
5. Other Policy and Technical Updates
a. Letter of Compliance Update
The Letter of Compliance is now only required for SINs 339940 and 339940OS4. SIN 339940OVER is being retired and removed from the form.
b. Aircraft SIN Scope Clarified
Fully assembled fixed-wing or rotary aircraft are no longer within scope for SIN 336413. GSA does not plan to introduce a new SIN for them, and future procurement will take place via alternate channels.
c. Prohibition on Using Government Data to Train AI
IT contractors must now ensure that government data is not used for AI/ML model training without written permission. This is a critical change for companies working in AI, cloud, or data services.
d. Template Revisions
GSA has updated all Product/Service Price Proposal Templates (PPTs) to simplify fields and improve clarity.
The MAS Refresh #26 is not just a spring cleaning — it’s a significant modernization push. For current contractors, this means:
Review your SINs immediately to check if you're impacted by the retirements.
Plan ahead for pricing updates, catalog revisions, and compliance actions.
If applicable, pursue new subcategories or subgroups, such as Program Evaluation or Cloud Services.
This refresh is designed to make the MAS program more efficient, responsive, and aligned with current acquisition strategies — but it also raises the bar for compliance and specialization. Feel free to contact us with any questions.
