FAR and DFARS › FAR Part 8: Required Sources of Supplies and Services

FAR 8.003 Use of other mandatory sources.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section tells agencies that for certain supplies and services, they must use specific mandatory sources rather than buying elsewhere. It matters to contractors because it limits how some government requirements can be fulfilled, pointing to other FAR parts for the details.
