FSC Product Codes Reference: Federal Supply Groups and How to Find Your Class

Federal Supply Classification (FSC) product codes are numeric. The first two digits identify a Federal Supply Group (FSG), such as furniture or hardware, and all four digits identify the class. Use this page to understand the structure and find your group. The full, current list of classes is in the PSC Manual on Acquisition.gov.

How are FSC product codes structured?

For example, group 71 covers furniture, and classes within it describe categories of furniture. The classes below each group are added, revised, and retired over time, so use the current manual for the exact list.

What are the main families of groups?

The groups fall into broad families. This is an overview, not a replacement for the manual.

Groups 10 to 20

Weapons, ordnance, missiles, aircraft, space vehicles, and ships. Many of these fall outside the commercial MAS

Groups 28 to 49

Engines, power transmission, machinery of various kinds, materials handling, refrigeration and air conditioning, fire fighting and safety equipment, pumps, plumbing, water treatment, piping, valves, and shop equipment

Titles and group boundaries change, so verify in the manual.

How do FSC codes relate to GSA MAS?

MAS is organized by SIN and large category, not by FSC. Products offered on MAS must fit a SIN. FSC codes help you with market research and marketing. A single SIN can cover multiple FSC classes, and one FSC class can appear under different SINs. See GSA MAS SINs Explained.

What else should product sellers know?

Products on MAS must also meet Trade Agreements Act requirements, and for certain offerings, Letter of Supply or Verified Products Portal requirements apply. See Trade Agreements Act Compliance and GSA Letter of Supply.
