How to bid on these
How do I find open federal contracts under NAICS 237110?
Federal buyers post solicitations on SAM.gov, and defence supply orders also appear on DIBBS. This page lists the ones open right now under NAICS 237110, soonest deadline first, and leaves out award notices, sole source intents and notices only existing contract holders can answer.
Do I need a SAM.gov registration to bid?
You need an active SAM.gov registration and a Unique Entity ID before an agency can award you a contract. Registration is free and takes a few weeks the first time, so start it before you find a solicitation you want.
What does a set-aside on a notice mean?
It means only companies of that type may compete. A small business set-aside is limited to companies under the SBA size standard for the NAICS code, and an 8(a), HUBZone, WOSB or SDVOSB set-aside also requires that certification on the date the offer is due.
Can I answer a sources sought or presolicitation notice?
Those take no bid yet, but answering one tells the agency a capable small business exists, which is often how work ends up set aside for small business. Each notice says what to send and by when.
Each notice lists its own due date and an amendment can change it, so check the latest version on SAM.gov before you submit. Browse by agency or see the market numbers.
