EU Battery Regulation 2023/1542: the ten questions importers ask most.

Plain-English answers to the ten most common compliance questions about EU Regulation 2023/1542. Each answer cites the specific Article or Annex it comes from. Updated as the regulation phases in.

What does EU Battery Regulation 2023/1542 require for imports?

Regulation (EU) 2023/1542 replaced the old Battery Directive 2006/66/EC on 18 February 2024. It is the single legal framework for placing batteries on the EU market — covering sustainability, traceability, transport safety, supply-chain due diligence and labelling. For an importer, the day-to-day customs-clearance checklist boils down to ten items: a current Declaration of Conformity citing 2023/1542, a correctly affixed CE mark, the six mandatory items on the battery label, the crossed-out wheeled bin pictogram, the cadmium or lead chemical symbol where applicable, a Digital Battery Passport (for in-scope categories from 18 February 2027), a UN 38.3 transport test summary, an Article 7 carbon-footprint declaration on the relevant phase-in date, compliance with the substance restrictions in Annex I, and an EU-established authorised representative for non-EU manufacturers. Missing any one of these can hold a container at customs.

When is the EU Battery Passport deadline?

The Digital Battery Passport becomes mandatory on 18 February 2027. From that date, every battery in three categories placed on the EU market must carry a per-unit QR code resolving to a public web URL with a structured JSON-LD payload that follows Annex XIII. The categories in scope are: Light Means of Transport (LMT — e-bikes, e-scooters, e-mopeds), industrial batteries above 2 kWh (forklift, AGV, telecom backup, behind-the-meter and grid-scale storage), and EV batteries (passenger cars, vans, trucks, buses). Portable consumer batteries — phone, laptop, tool — are out of scope today and expected to be brought into scope by 2030. The passport is per-unit, not per-SKU: one QR code per physical battery, each pointing to a unique URN:UUID identifier and its own data record.

What must a battery Declaration of Conformity contain?

The Declaration of Conformity is the manufacturer's signed legal statement that the battery meets every applicable EU requirement. Without it, the product cannot legally be on the EU market. Annex IX requires a single document — typically one or two pages — containing: the battery model, type and serial-number range; the manufacturer's name and full registered postal address (a P.O. box is not sufficient); the EU authorised representative where the manufacturer is non-EU; a "sole responsibility" statement; the object of the declaration with traceability to the specific units; every applicable Union law (Regulation 2023/1542 must be on the list, replacing the repealed Directive 2006/66/EC); the harmonised standards applied (e.g. EN IEC 62133-2 for cell safety); notified-body details where a conformity-assessment route required one; the place and date of issue; and the name, function and signature of an empowered individual — not "Compliance Department". The DoC must be issued in English plus the destination Member State's language.

Does my battery need a CE mark, and what does it have to look like?

Yes. Every battery placed on the EU market must carry a CE mark, affixed to the battery itself — visibly, legibly and indelibly. If physical constraints (very small batteries, sealed-in packs) prevent that, the mark goes on the packaging and on the documentation accompanying the battery. The minimum height is 5 mm, scaled proportionally for smaller batteries. The mark must follow the official EU graphical proportions; stretched, distorted or "logo-style" CE marks fail conformity. A common spoof to watch for is the China Export "CE" — visually similar but legally meaningless; the genuine CE has a distinct gap between the C and the E, while the China Export letters touch. If a notified body performed the conformity assessment, the body's four-digit identification number must appear immediately after the CE mark.

What information must be on a battery label?

Annex VI Part A specifies six pieces of information that must appear on every battery sold in the EU, plus mandatory pictograms. The six items are: (1) the manufacturer's name and contact address; (2) battery type, model and batch or serial number; (3) date of manufacture in a human-readable format; (4) weight, in grams or kilograms; (5) capacity, in milliampere-hours (mAh) for portable batteries or watt-hours (Wh) for industrial, EV and LMT batteries above the relevant threshold; (6) chemical composition (Li-ion, NiMH, NiCd, lead-acid, etc.). On top of those six, two pictograms are mandatory where applicable: the crossed-out wheeled bin (separate-collection / WEEE symbol) on every battery, and the chemical symbol "Cd" or "Pb" directly underneath the bin where the battery contains more than 0.002% cadmium or 0.004% lead by weight.

Which batteries need a Digital Battery Passport?

From 18 February 2027, three categories require a Battery Passport: Light Means of Transport (LMT — e-bikes, e-scooters, e-mopeds, electric kick-bikes), industrial batteries with a capacity above 2 kWh, and EV batteries. The passport is a public web URL encoded in a QR code (ISO/IEC 18004) printed on the battery or its packaging. The URL contains an ISO/IEC 15459 unique product identifier — typically URN:UUID:<v4 UUID> — and resolves to a JSON-LD payload following the Annex XIII schema. The data is split into three access tiers: public (model identifier, manufacturer, weight, dimensions, capacity, chemistry, recycled content, carbon footprint, end-of-life contact), legitimate-interest (visible to repairers and recyclers), and authorities-only (for customs and market surveillance). Each physical battery must have its own unique passport — one QR shared across multiple units does not comply.

Do I need a UN 38.3 transport test summary for lithium batteries?

Yes. Every lithium cell or battery — primary lithium-metal or rechargeable lithium-ion — must pass the eight tests defined in UN Manual of Tests and Criteria Section 38.3: altitude simulation, thermal cycling, vibration, shock, external short circuit, impact or crush, overcharge, and forced discharge. The result is a standalone "UN 38.3 Test Summary" document that must travel with the battery. A passing reference in the Declaration of Conformity is not sufficient; customs needs the actual summary document containing the manufacturer name, cell or battery model, mass in grams, type (cylindrical, prismatic, pouch, button), watt-hour rating or lithium content, a physical description, a list of tests performed and each result, the test laboratory's report number and date, and the edition of the UN Manual used. The current edition is Rev.7 with Amendment 1; older editions (Rev.5, Rev.6) are no longer accepted for new shipments.

When is the Article 7 carbon-footprint declaration mandatory?

Article 7 phases in by battery category. EV batteries have required a verified carbon-footprint declaration since 18 February 2025; the performance-class label is mandatory from 18 August 2026, and a maximum-footprint threshold becomes enforceable on 18 February 2028. Industrial batteries above 2 kWh have required the declaration since 18 August 2026; the class label follows on 18 February 2028, and the threshold on 18 February 2030. LMT batteries follow on 18 February 2028 for the declaration. Portable batteries are out of scope at this level, with a future amendment expected. Every declaration must use the EU Joint Research Centre's PEFCR for batteries methodology, be expressed in kg CO₂-equivalent per kWh of energy delivered over the battery's expected service life, broken down by life-cycle stage, and be verified by a notified body or accredited verifier — self-declaration is not accepted for the regulatory record.

What are the EU substance restrictions for mercury, cadmium and lead in batteries?

Three substances are restricted across all battery categories with very narrow exceptions. Mercury (Hg): zero. No battery placed on the EU market may contain mercury at all; the old button-cell exemption was withdrawn in 2024. Cadmium (Cd): zero in portable batteries, with the narrow exception of cadmium in industrial batteries used for emergency lighting and alarm systems. NiCd batteries for general consumer use have been off the EU market since 2009. Lead (Pb): restricted to less than 0.01% by weight in portable batteries. Lead-acid traction and starter batteries are exempt and remain legal — but they must carry the "Pb" chemical symbol on the label. REACH Regulation (EC) 1907/2006 and the RoHS Directive 2011/65/EU impose additional substance restrictions on adjacent components such as cables, connectors and battery-management-system PCBs.

Does a non-EU battery manufacturer need an authorised representative in the EU?

Yes. Every manufacturer whose registered office is outside the EU and who places batteries on the EU market must appoint an EU-established authorised representative. The authorised representative is a legal entity inside the Union that takes regulatory responsibility on the manufacturer's behalf — they hold the technical file and the Declaration of Conformity (available for inspection by market-surveillance authorities for ten years after the last unit was placed on the market), cooperate with authorities on requests for information, recalls and non-compliance investigations, and are named in the DoC and on the documentation accompanying the battery. The representative must have a full registered EU address and a written mandate from the manufacturer. The importer can act as authorised representative, but the import relationship does not auto-create AR status — a separate signed mandate is required.
