FAR 23.304 Contract clauses.

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 contracting officers which clauses to include in solicitations and contracts involving hazardous materials or radioactive materials. It matters to contractors because it determines whether clauses like 52.223-3 or 52.223-7 will appear in their contract, which can create notice and identification obligations.

Applies to: Contracting officers and contractors on solicitations or contracts involving hazardous or radioactive materials
