EU Battery Regulation Due Diligence Report Deadline

The EU Battery Regulation’s due diligence reporting deadline moved from 2025 to 18 August 2027 under Regulation (EU) 2025/1561 — a separate obligation and a separate date from the battery passport’s 18 February 2027 mandate, and the two get conflated constantly.

Why AuthiChain

• Regulation (EU) 2025/1561, in force since 31 July 2025, delays the Article 52 due diligence policy obligations to 18 August 2027 and moves the public reporting cycle from annual to every three years
• The battery passport’s data — carbon footprint, state-of-health, material composition — and the Article 52 due diligence report are separate obligations under the same regulation, on separate timelines; a passport record does not by itself satisfy the due diligence duty
• The Commission’s due diligence guidelines, originally due 18 February 2025, are now expected by 26 July 2026 — a battery manufacturer building a due diligence process today is building against guidance that has not shipped yet

FAQ

Does the due diligence delay also push back the battery passport deadline?

No — 18 February 2027 remains the battery passport mandate. Only the separate Article 52 due diligence policy and reporting obligations moved to 18 August 2027 under Regulation (EU) 2025/1561.

Does this delay apply to the whole Battery Regulation?

No — it applies specifically to Article 52 due diligence policy obligations. Other Battery Regulation duties, including the 18 February 2027 passport mandate, are unaffected.
