The Framework

Public discussion of 10 USC 4865 compliance treats it as a countdown: 2028 for new programs, 2029 for standard batteries, 2031 for existing programs. That framing understates the problem.
Three clocks are running simultaneously at different speeds. Clock 1 is the statutory deadline: fixed, public. Clock 2 is the qualification timeline: FAT completion, QPL listing under MIL-PRF-32565, production ramp. Program-specific, mostly invisible, subject to full restart if a cell-origin change triggers a new first article. Clock 3 is public compliance infrastructure: DFARS clauses, the compliance repository due January 2027, waiver documentation standards. As of this Independence Day weekend, no proposed or final DFARS rule implementing Section 4865 has appeared in the Federal Register.
Procurement risk concentrates in the gaps between clocks. A program facing a 2028 Clock 1 deadline whose supplier discovers FEOC exposure in 2027 hits a Clock 2 restart that cannot complete before Clock 1 fires, and currently lacks the Clock 3 infrastructure to formally document a waiver. The statute anticipated this, building in one-year exemptions. Whether waivers become the early operating model is an open question with no public artifact to answer it yet.
This section tracks where each clock stands and where the gaps are widening.
The Mandate Gap — Section 4865 / January 1, 2028

The 180-day DFARS rulemaking window for Section 4865 closed in mid-June with nothing in the Federal Register. No proposed rule, no implementing clause, no cost-accounting methodology. Eighteen months to the new-program deadline, zero suppliers have publicly demonstrated compliance with the 95% non-FEOC component-cost threshold, and the compliance repository Congress mandated for defense sourcing requirements excludes batteries by its own statutory terms. Mapping the gap across all three clocks—statute, qualified supply, implementation infrastructure—points to systematic waiver issuance as the most probable operating model for January 2028.

The Qualification Clock Is the Real Deadline for Defense Battery Compliance

Section 4865 gives DoD until January 2029 to stop buying standard batteries with covered-nation functional cell components. The public procurement record for 6T lithium-ion batteries under MIL-PRF-32565 shows no qualified suppliers on the QPL, SBIR topics still addressing thermal-runaway mitigation at Phase I, and a missed DFARS implementation deadline with no procedural artifacts. Any cell-origin change made for compliance triggers First Article Testing — a sequential process measured in years, not months. The mandate clock is public and specific. The qualification clock runs longer, and the two do not converge.
