What it makes you produce

One item for your checklist.

  1. Something you write

    Days to weeks, and nobody outside your company has to agree to it.

    • A written request to the contracting officer for authorization to incorporate hexavalent chromium

      Owed when a deliverable or construction material has to carry hexavalent chromium — and before it is made, since (b) otherwise bars delivering it

      DFARS 252.223-7008(c)

When it is used

Goes in, per the 223.7306 prescription, in contracts for supplies, maintenance and repair services, or construction materials. It prohibits a deliverable or construction material that (i) contains hexavalent chromium above 0.1% by weight in any homogeneous material, or (ii) requires removing/reapplying hexavalent chromium material during sustainment phases. Exception: Cr(VI) generated as a manufacturing process by-product. Intentional use only with authorization requested from the Contracting Officer. Flows down into all subcontracts for the same subject matter — including commercial ones.

Read closely

(b)(1) bars a deliverable whose homogeneous material carries more than 0.1 percent hexavalent chromium by weight, and bars one that needs chromate removed and reapplied later in service; (b)(2) leaves out hexavalent chromium produced as a by-product of a manufacturing process. The measurement is per homogeneous material as (a) defines it — what cannot be mechanically disjointed, so an individual plating, paint or alloy — and that definition expressly does NOT include conversion coatings that chemically modify the substrate. Chromated primers and hard chrome are where this usually lands.

Source: acquisition.gov, DFARS 252.223-7008. CODIFIED REGIME, read 2026-08-11 on the part-252 page at DFARS Change 5/7/2026: "As prescribed in 223.7306, use the following clause:" with designation (JAN 2023). RFO CLASS DEVIATION 2026-O0018 (DFARS part 223, effective February 1, 2026) CARRIES THIS CLAUSE AT THE SAME NUMBER: the memo prescribes it at 223.7306 and prints it (JAN 2023). So the two regimes AGREE here on number, prescription and designation, and an agreement read is recorded because the alternative is silence that a reader cannot tell from an unread deviation.

Both regimes read against their primary sources on 2026-08-11, and the deviation half re-read a second time and the recipe above measured on 2026-08-11 (verified 2026-08-11)

This is research, not legal advice. It states what the regulation says about this clause and cites the paragraph behind it. It does not rule on your order, and it does not rule on whether a prime's markings are correct.
