Federal defense bids in Ohio: 212 open in November 2026

Defense buying spans every category. Spare parts from the Defense Logistics Agency are often quoted on DIBBS, its own bid board. Notices may release drawings only to firms certified in the Joint Certification Program (DD Form 2345), require ITAR registration for defense articles, and add cybersecurity clauses (NIST SP 800-171, CMMC) when controlled unclassified information is involved. Common NAICS codes: 336413, 336611, 332994 and 334511.

Contracting officers set a purchase aside for small businesses when they expect offers from at least two capable small firms at fair prices (the rule of two). Whether a firm counts as small depends on the SBA size standard for the notice's NAICS code, in annual receipts or employees, and offerors need an active SAM.gov registration with a Unique Entity ID.

A general guide to the buying rules, not legal advice. Each solicitation sets its own terms.
