GSA MAS Contract Categories: What Can You Sell?

What are the GSA MAS large categories?

Since the 2019 to 2020 consolidation of the legacy numbered schedules (Schedule 70, Schedule 84, 00CORP and many others) into one solicitation, GSA has grouped the MAS into 12 large categories:

Category descriptions are summaries. The controlling scope language for each SIN is in the current MAS solicitation and on GSA’s category pages, so always confirm there before you build an offer around a specific SIN.

Is there a Medical category?

Not as a stand-alone MAS large category. Medical equipment and laboratory solutions sit primarily under Scientific Management and Solutions. Separately, the Department of Veterans Affairs (VA) runs its own Federal Supply Schedule program for many medical and pharmaceutical items, which is administered under different terms. If your business sells medical products, confirm which program covers your items before you invest in an offer.

How are SINs different from categories?

Think of the large category as the aisle in a store and the SIN as the shelf. The category tells you the general territory. The SIN tells GSA exactly what you are allowed to sell, what evaluation criteria apply, and, for many SINs, what supporting documentation your offer needs.

You can list your offerings under more than one SIN, and even under more than one category, as long as your offer supports each one. For a deeper walk-through of SIN selection, see GSA MAS Schedule Categories, SINs and How to Get Listed.

What about old schedule numbers?

References to Schedule 70, Schedule 36, 00CORP and similar legacy names still appear in older contracts, vendor websites, and buyer conversations. Those schedules were folded into the MAS. Contracts awarded under them were migrated, and new offers are submitted under the single MAS solicitation, 47QSMD20R0001. If you see a vendor pitching a “Schedule 70 application,” treat that as a sign the material is out of date.

How do you find the right category for your business?

1. List what you actually sell today and can support with commercial sales or, for services, past performance.
2. Search GSA eLibrary and GSA’s category pages for the SINs that describe those offerings.
3. Read the SIN scope and any SIN-specific offer requirements in the current solicitation and offer instructions.
4. Confirm the fit before you start building pricing. A SIN mismatch is a common reason offers stall.

Once you have a likely fit, the next step is the offer itself. Start with How to Get on the GSA Schedule, or contact TurboGSA to talk through your situation.
