Implementation guide for Chinese companies

A step-by-step five-stage compliance process: each stage sets out the goal, operational points, prerequisites, expected results and potential risks.

Legal source: Regulation (EU) 2023/1542, its annexes and harmonised standards · Verification baseline 2026-10-09

01Strategy definition and responsibility mapping

Goal: Clarify product classification and the company’s legal identity in the supply chain, and determine the applicable compliance path.

Determine the battery category and capacity threshold

  • Calculate industrial battery energy under IEC 61960 (rated capacity Ah × nominal voltage V), not merely from the nominal value on the label, to determine whether the 2 kWh threshold is exceeded.
  • Confirm whether the product is a “stationary battery energy storage system” (stationary BESS). Portable units (e.g. power banks that also provide propulsion) do not fall into this category and may be exempt from some BMS reset requirements.
PrerequisitesDetailed electrical specification sheets for the product
Expected resultClear identification of which SKUs need a carbon footprint and battery passport (>2 kWh industrial / EV / LMT) and which need only baseline compliance
Potential riskIf the regulator does not accept the IEC 61960 calculation, borderline products (e.g. 1.9 kWh) may be forced into the high-compliance-cost zone

Determine “producer” status (EPR responsible party)

  • Apply the EUROBAT scenario analysis tool to determine the registration responsible party by trade term (DDP/FOB) and customer type (OEM/distributor/end user).
  • Cross-border e-commerce (direct sales to end users): immediately start the process of appointing an EPR authorised representative in the country of sale.
PrerequisitesClear sales contracts and a logistics route map
Expected resultClarity on whether to register for EPR and pay yourself, or leave it to the EU customer; avoid double payment or compliance gaps
Potential riskMember States apply different definitions of “first placing on the market”, which may result in conflicting registration requirements across countries

02Building the supply-chain data architecture

Goal: Build a supply-chain traceability system that can pass third-party verification, in preparation for carbon footprint and due diligence.

Implement an OECD due diligence system

  • Establish a management system based on the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.
  • Limit the traceability scope to the battery cell level; exclude non-chemical components such as casings and screws for now.
  • Require Tier 1 suppliers to disclose the names and countries of origin of their direct suppliers of upstream raw materials (cobalt, lithium, nickel, graphite).
PrerequisitesSupply-chain transparency agreements signed
Expected resultAnnual due diligence report produced (can be integrated into the ESG report), ready for notified body audit
Potential riskUpstream miners falsify data or refuse transparency, making third-party verification impossible and the product barred from the market

Carbon footprint data modelling and accounting

  • Build an LCA model based on the PEF (Product Environmental Footprint) methodology.
  • Collect primary data for specific factories and specific models; use of averaged data across different factories is strictly prohibited.
  • Exclude “carbon offset” data and count only actual emissions.
PrerequisitesFactory-level energy consumption and bill of materials (BOM) data complete
Expected resultCarbon footprint declaration (kg CO₂e/kWh) generated and filed in the technical documentation
Potential riskDelegated acts are delayed or detailed rules change abruptly, invalidating earlier models and compressing the compliance window

03Product engineering and testing

Goal: Adjust product design to meet physical performance, safety and data access requirements.

Develop open BMS data interfaces

  • Design BMS firmware that can record and output state of health (SOH) and expected lifetime data in read-only form.
  • Develop a software reset function for EV and LMT batteries.
  • Confirm that non-smart industrial batteries (e.g. lead-acid) are exempt from the BMS installation obligation.
PrerequisitesBMS hardware supports data storage and communication
Expected resultBMS data meets Annex VII requirements and supports repurposing assessment
Potential riskInaccurate BMS algorithms cast doubt on SOH data, leading to disputes in second-hand sales or hindering repurposing

Removability and safety design

  • Verify the “easy removability” of portable batteries under EN 45554:2020 (using commercially available tools).
  • Carry out the safety tests specified in Annex V (thermal shock, short circuit, thermal propagation, etc.).
  • Conduct a risk assessment using FMEA (failure mode and effects analysis) and include it in the technical documentation.
PrerequisitesR&D team familiar with EN standards and EU safety parameters
Expected resultProduct passes safety tests and the design meets right-to-repair requirements
Potential riskOver-integration (CTP/CTC) makes “removable by independent professionals” impossible to meet, requiring new tooling

04Conformity assessment and digitalisation

Goal: Complete the legal paperwork, obtain the CE marking and deploy digital tools.

Choose the conformity assessment module

  • General safety requirements use Module A (internal production control), self-declared by the manufacturer.
  • For carbon footprint, recycled content and similar indicators, a notified body must perform Module D1 (quality assurance of the production process) or Module G (unit verification).
  • Screen qualified notified bodies in the NANDO database.
PrerequisitesISO 9001 quality system in place (the basis for Module D1)
Expected resultNotified body certificate obtained and EU declaration of conformity (DoC) signed
Potential riskInsufficient notified body capacity causes backlogs, preventing the necessary certificates from being obtained before shipment

Deploy the battery passport and QR code

  • Choose a decentralised data solution and generate a unique identifier compliant with ISO/IEC 15459.
  • Generate a QR code, ensure it contains some offline data (stored locally), and affix it in a prominent position on the battery.
PrerequisitesIT systems have collected all compliance data (carbon footprint, material composition, etc.)
Expected resultEvery battery has a unique digital identity, with data accessible to different permission levels
Potential riskThe chosen third-party passport platform is incompatible with EU data standards (e.g. Catena-X), requiring costly migration later

05Logistics and after-sales

Goal: Ensure compliant physical delivery and a closed loop for waste battery management.

Digital documentation accompanying shipments

  • Keep paper documents accompanying shipments only for safety information.
  • Provide non-safety documents such as carbon footprint declarations and instructions via digital links/QR codes to reduce packaging costs.
PrerequisitesStable hosting servers for digital documentation
Expected resultCompliant with the Blue Guide, reducing logistics material costs
Potential riskCustoms in some conservative Member States insist on a full set of paper documents, causing goods to be held

Repurposing and waste management

  • If repurposing (e.g. from traction to storage), re-assess conformity under Module A and issue a new DoC.
  • When exporting second-life batteries, provide SOH test reports (capacity/impedance tests) and sales contracts to prove they are not “e-waste”.
PrerequisitesIn-house battery condition testing capability or a partner
Expected resultLawful cross-border transport of second-life batteries, avoiding allegations of illegal waste shipments
Potential riskRe-certification costs are too high, the repurposing business model fails, and batteries are forced into direct recycling
