MAS Categories

Available offerings under the consolidated Multiple Award Schedule (MAS) are organized by large category, subcategory and Special Item Number (SIN). The 12 large category pages are listed on the left side of this page and provide information specific to these categories. For general information on MAS, please visit the About GSA Schedules Page.

Supplies and services can be ordered directly from GSA Schedule contractors or through our GSA eTools, including GSA Advantage!® and GSA eBuy. When using MAS, ordering activities have the opportunity to meet small business goals, while promoting compliance with various environmental and socioeconomic laws and regulations. The MAS Solicitation is found on and a list of available Schedule holders is found on GSA eLibrary.
