GSA utilizes Special Item Numbers (SINs) to categorize the product or service offerings contractors can have awarded on the Multiple Award Schedule (MAS). Many SINs require contractors’ or offerors’ services to meet specific standards or regulations to have the SIN awarded. A popular SIN that limits the types of services vendors can provide is the Engineering Services SIN or SIN 541330ENG.

However, the Engineering SIN is not the only SIN that limits engineering firms in their service offerings; the Environmental Consulting Services SIN also requires contractors or offerors looking to add this SIN to meet a few requirements.
