The EU Battery Regulation (EU) 2023/1542 has been circulating in Chinese-language trade press since it entered into force in August 2023, and by now most exporters have heard the broad strokes: carbon footprint declarations, supply chain due diligence, a digital battery passport. What’s less consistently reported — because the regulation rolls out in phases stretching to 2036 — is which of these obligations are live right now, and which have since been delayed.
That distinction matters for anyone sourcing or manufacturing batteries for the EU market, because treating a 2027 deadline as a 2025 emergency wastes resources, while treating a 2026 deadline as still years away creates real exposure.
What’s Already in Force
The regulation applies to five battery categories — portable, industrial (including light means of transport, or LMT), automotive (SLI), electric vehicle, and stationary energy storage — with CE marking against the new requirements already mandatory since the regulation’s general application date of August 18, 2025, when it fully replaced the old 2006 Battery Directive.
Carbon footprint declarations for EV batteries became mandatory on February 18, 2025. As of February 18, 2026, that same requirement extends to rechargeable industrial batteries above 2 kWh — meaning any factory or trading company shipping industrial batteries into the EU this year needs a lifecycle carbon footprint declaration per battery model, calculated per manufacturing plant, ready to go.
What’s Coming in 2027
Two significant obligations are still ahead:
- The Digital Battery Passport becomes mandatory on February 18, 2027, for industrial batteries above 2 kWh, EV batteries, and LMT batteries. It’s a QR-code-accessible record covering material composition, carbon footprint, and lifecycle data — effectively a standing data infrastructure requirement, not a one-time filing.
- Carbon footprint performance classes and eventual maximum thresholds follow after the initial declaration phase, with maximum life-cycle thresholds for some categories not arriving until 2028.
The Due Diligence Delay Worth Knowing About
Here’s where a lot of earlier guidance — including much of what was published in Chinese trade media in 2023 and 2024 — is now out of date. The original text of the regulation required supply chain due diligence obligations (covering responsible sourcing of cobalt, lithium, nickel, and graphite) to begin two years after entry into force, which pointed to August 2025.
That deadline has since been postponed. Regulation (EU) 2025/1561, published July 30, 2025, amended the due diligence provisions and pushed the compliance date to August 18, 2027. If a supplier, consultant, or article is still telling you due diligence obligations are already active, that information predates the 2025 amendment and should be treated as outdated.
This delay applies to economic operators placing batteries on the EU market with annual turnover above €40 million; smaller operators have separate, lighter-touch obligations under the regulation.
Why “Delayed” Isn’t the Same as “Not Urgent”
Compliance advisors working with battery manufacturers generally caution against treating the due diligence extension as a reason to wait. The obligation requires internal systems, supplier data collection, and third-party verification — infrastructure that takes time to build regardless of when enforcement technically begins. A supplier who starts mapping cobalt and lithium sourcing chains only in early 2027 is working against a compressed timeline; one who starts now has room to work through the inevitable data gaps.
The same logic applies to the Battery Passport. Since it requires structured, QR-code-linked data per battery model, the underlying data collection work — bill of materials, energy inputs, plant-level emissions data — needs to be in place well before the February 2027 deadline, not assembled in the weeks before it.
Practical Takeaway for Suppliers and Buyers
For anyone currently sourcing batteries — or battery-containing products — for the EU market, three questions are worth asking a supplier right now:
- For industrial batteries above 2 kWh: is there a carbon footprint declaration on file for this specific model and manufacturing plant, given the February 2026 deadline is now active?
- Is the supplier’s understanding of the due diligence timeline current — August 2027, not August 2025 — or are they working from outdated guidance?
- Has any groundwork started on the data infrastructure the Battery Passport will require in 2027, even though the formal deadline is still ahead?
One industry estimate places China’s share of global EV battery production at around 77% — a figure worth treating as directional rather than precise, since it comes from a single industry analysis rather than an official EU or Chinese government source. Whatever the exact number, it’s a large enough share of the market that the compliance timeline above is relevant well beyond companies that consider themselves “battery exporters” in the narrow sense — it also affects manufacturers of e-bikes, power tools, and consumer electronics where the battery is a component rather than the product itself.
