What it makes you produce

2 items for your checklist, slowest first.

  1. Something you write2

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

    • A written notice to the contracting officer describing the part, the isotope, its activity and the manufacturer, the stated number of days before delivery or before servicing is complete

      FAR 52.223-7(a)

    • MIL-STD-129 marking and labels on every item, part or subassembly above the activity criteria, and on the containers they ship in

      FAR 52.223-7(c)

When it is used

Supplies contracts where the item contains radioactive material that requires a license under the Atomic Energy Act or has specific activity above 0.002 microcuries/gram ((a)). The advance-notice period is filled in by the Contracting Officer in the contract (the text leaves the number of days blank). No dollar threshold.

Read closely

The number of days is filled in by the contracting officer, set to leave time for licenses and safety precautions at the receiving end — a blank there is a question rather than a zero. (b) lets a repeat delivery of unchanged material go forward on a written waiver request naming the earlier notice and its contract number. The trigger sits in the bill of materials: sights, dials, smoke detectors and luminous instruments are the usual carriers.

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.
