Commodity Code Lookup
This tool allows for search and review of commodity codes and is for reference purposes only. Vendors must add commodity codes to their account via the SIGMA VSS system.
Go to SIGMA VSSAbout Commodity Codes
Commodity codes are a numerical classification system that correlate to various goods and services. When vendors register to do business with the state, they add commodity codes to their account in SIGMA VSS that correspond to the goods and services they sell. The State of Michigan uses the National Institute of Governmental Purchasing (NIGP) code system. Commodity codes are sometimes referred to as "NIGP codes" for this reason.
The Importance of Commodity Codes
There are three primary reasons you should select commodity codes and keep them updated:
- Bid Notifications. Including commodity codes and email addresses in your SIGMA VSS profile is the only way to be notified of state bid opportunities.
- Additional Opportunities. Michigan schools and other local governments use SIGMA VSS. Identifying the correct commodity codes for your business ensures that the system will notify you of bids that match your codes.
- Tells a Story. Commodity codes are the best and quickest way to communicate to the state what products and services your company can provide. This helps us understand our bidder pool and categorize opportunities appropriately.
NIGP versus NAICS Codes
Federal procurement systems such as SAM.gov use North American Industry Classification System (NAICS) codes. This is a similar but different system than NIGP codes which the State of Michigan uses.
The State of Michigan does not use NAICS codes. The State of Michigan uses NIGP codes.
