Large Categories, SINs, and NAICS Codes

How the GSA Schedule is Organized

The GSA Schedule is organized by Large Categories, Subcategories, and then Special Item Numbers (SINs) that have corresponding North American Industry Classification System (NAICS) codes. There are 12 Large Categories and each corresponds to a different industry, such as Information Technology, Office Furniture, or Industrial Products. There are 315 SINs and each are specific products and service subcategories that define and further narrow down your proposed pricelist. GSA Schedule contractors can propose any of the Large Categories and the associated SINs in their offer or add them to their contract pricelist at any time – all under one GSA Schedule contract.

NAICS codes are six-digit numerical codes that are used as the standard to classify businesses and government contract opportunities. The GSA Schedule SINs match or closely resemble NAICS codes.

The table below features the 12 Large Categories A-L and their subsequent SINS. The SINs are further organized into subcategories to help you find which SIN works best for your company.
