Carbon Footprint Declaration No mandatory equivalent. China has voluntary product carbon footprint standards (GB/T 24067, aligned with ISO 14067) and pilot carbon labelling schemes in some provinces, but no binding CFD obligation for batteries.GB/T 24067-2024 (voluntary, product carbon footprint)
No binding CN battery-specific CFD regulation as of 2026-06-11		 Industrial batteries (≥2 kWh) and EV batteries must carry a carbon footprint declaration (CFD) per lifecycle stage, calculated per harmonised methodology. CFD obligations are conditional on the entry into force of the Commission delegated act (methodology) and implementing act (declaration format): EV batteries apply 12 months after the later of those two acts; industrial batteries (≥2 kWh, including BESS) apply 18 months after the later act. As of 2026-06-12, neither the EV battery nor the industrial battery delegated act has been published in the Official Journal — the draft EV methodology was consulted in April 2024 and the JRC industrial battery technical report was published in April 2025. The indicative dates in the Regulation text (18 February 2025 for EV; 18 February 2026 for industrial) will shift depending on when the acts are formally published.Regulation (EU) 2023/1542, Articles 7 & 8

Commission delegated act on CFD methodology for industrial batteries (JRC technical report published April 2025; delegated act not yet published in Official Journal as of 2026-06-12 — application dates conditional, triggering 18 months after OJ publication)		 Chinese manufacturers have no domestic obligation to calculate or declare battery carbon footprints. Establishing lifecycle GHG inventory, third-party verification, and EU-aligned reporting systems represents a significant new compliance burden.High gap. No Chinese domestic rule mirrors this obligation. Exporters targeting EU markets must build new CFD capability from scratch. Official Journal of the European Union2026-06-11 · unverified
CE Marking & Conformity Assessment under EU Battery Regulation China has mandatory CCC (China Compulsory Certification) for certain battery products and GB standards (e.g. GB/T 36276 for lithium-ion batteries for energy storage). However, CCC scope and technical requirements differ substantially from EU Battery Regulation conformity assessment.CCC (China Compulsory Certification) system
GB/T 36276-2023 (lithium-ion batteries for electrochemical energy storage)
GB 38031-2020 (EV traction battery safety)		 Batteries placed on the EU market must bear CE marking demonstrating conformity with all applicable requirements of Regulation (EU) 2023/1542, including safety, performance, labelling, and sustainability. Conformity assessment procedures (internal control or third-party notified body depending on category) must be completed and an EU Declaration of Conformity (DoC) issued.Regulation (EU) 2023/1542, Articles 18–24 (CE marking and conformity assessment)
Regulation (EU) 2023/1542, Annexes VIII–IX		 CE marking under the Battery Regulation requires demonstrating conformity with sustainability, carbon footprint, and due-diligence obligations — far beyond a product-safety CCC. Chinese exporters must engage EU notified bodies and maintain technical documentation aligned to the Regulation's expanded scope.High gap. CE marking scope under this Regulation is broader than product safety alone; existing CCC does not substitute for EU conformity assessment.

Supply Chain Due Diligence Policy No mandatory equivalent. China has voluntary responsible sourcing guidelines (e.g. CAAM/CATL voluntary initiatives) and participates in some international initiatives, but no binding domestic law requires battery supply chain due diligence disclosure comparable to Article 48.No binding CN equivalent as of 2026-06-11
CAAM Responsible Battery Initiative (voluntary)
CATL ESG disclosures (voluntary)		 Economic operators placing industrial, EV, and SLI batteries (above thresholds) on the EU market must adopt and implement a supply chain due diligence policy covering sourcing of cobalt, natural graphite, lithium, and nickel, including risk identification, mitigation, third-party audits, and public disclosure. Regulation (EU) 2023/1542 Article 48(2) exempts operators whose net annual turnover in the preceding financial year did not exceed EUR 40 million and who are not part of a group; the obligation now applies from 18 August 2027 following postponement by Regulation (EU) 2025/1561 (published 30 July 2025).Regulation (EU) 2023/1542, Article 48 (due diligence policy)
OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (referenced in Reg)		 Chinese battery exporters to the EU must build formal due diligence management systems, conduct third-party audits of upstream mineral suppliers, and publicly disclose findings — obligations with no domestic Chinese parallel. This is a structural compliance gap affecting most mid-size manufacturers.Critical gap. No Chinese law mirrors this obligation. Exporters must implement OECD-aligned due diligence programs and prepare for third-party audits to access the EU market. Official Journal of the European Union2026-06-11 · unverified
Labelling, QR Code & Battery Passport China requires product labelling per GB standards (e.g. GB/T 36276, GB 38031) covering basic safety and capacity information. No equivalent to the EU Battery Passport digital traceability system exists in Chinese regulation.GB/T 36276-2023 (product marking requirements)
GB 38031-2020 (labelling requirements for EV batteries)
No CN Battery Passport equivalent as of 2026-06-11		 All batteries must carry prescribed labels (capacity, chemistry, hazard symbols, recycled-content share, QR code). Basic labelling (including separate-collection symbol) mandatory from 18 August 2025; extended labelling requirements (additional Article 13 fields) from 18 August 2026 or 18 months after the relevant implementing act, whichever is later. Industrial batteries ≥2 kWh and EV batteries must also have a digital Battery Passport accessible via QR code, containing lifecycle, carbon footprint, state-of-health, and supply chain data. Battery Passport mandatory from 18 February 2027. Technical data-attribute specifications remain subject to delegated acts not yet adopted as of 2026-06-11.Regulation (EU) 2023/1542, Articles 13–14 (labelling), Article 77 (Battery Passport)
Delegated acts on Battery Passport data attributes (not yet published in the EU Official Journal as of mid-2026; the Battery Passport is mandatory from 18 February 2027 but the technical data-attribute specifications remain subject to delegated acts still in preparation — monitor EUR-Lex for publication)		 The Battery Passport is an entirely new digital compliance infrastructure requirement with no Chinese parallel. Exporters must develop or integrate with EU-recognised passport platforms, collect and maintain granular lifecycle data, and update labels to EU specifications — a significant operational and IT investment.High gap. Battery Passport represents a paradigm shift to digital product transparency. Chinese manufacturers must invest in data infrastructure and third-party platform integration well ahead of the 18 February 2027 mandatory date.

Fire Safety & Thermal Runaway Propagation — BESS (EU/International) GB/T 36276-2023 (revised, released 6 August 2023 by SAC/SAMR, in force from 1 March 2024, superseding GB/T 36276-2018) covers lithium-ion battery packs and systems for stationary energy storage, including thermal-runaway tests at cell and module level. The 2023 revision tightened test conditions (e.g. external short-circuit resistance reduced from 5 mΩ to 1 mΩ) and expanded abuse-test coverage. However, the propagation-prevention test methodology and pass/fail thresholds differ from IEC 62933-5-2. GB/T 36276 does not adopt UL 9540A protocols, and system-level fire-compartment propagation data generated under Chinese test conditions is generally not in the format required by EU installers or AHJs.GB/T 36276-2023 — Lithium-ion battery packs and systems for electric energy storage (released 6 August 2023, in force 1 March 2024, supersedes GB/T 36276-2018; recommended national standard)
GB/T 51048-2025 — Standard for Design of Electrochemical Energy Storage Power Station (supersedes GB 51048-2014; issued 31 December 2025, effective 1 April 2026)		 IEC 62933-5-2:2020 sets safety requirements for grid-connected energy storage systems, including evaluation of thermal runaway propagation at cell, module and system level. Ed 2.0 remains in development and does not supersede the 2020 edition for this dataset. Installations must demonstrate that thermal runaway in one cell does not propagate uncontrolled to adjacent cells/modules. Many EU member-state building codes and installers additionally require UL 9540A fire-test data to quantify heat release and propagation risk for fire-compartment design. EN IEC 62933-5-2 is the harmonised European adoption (harmonised status under OJ review as of 2026-06-11).IEC 62933-5-2:2020 — Electrical energy storage (EES) systems – Part 5-2: Safety requirements for grid-integrated EES systems

EU installers and AHJs increasingly request UL 9540A-format data even where not legally mandated, because it feeds fire-compartment sizing calculations. Chinese manufacturers rarely commission UL 9540A tests. This documentation gap is a frequent barrier at the EU project-finance and permitting stage.INFORMATIONAL ONLY — Chinese BESS products certified to GB/T 36276 alone are likely to face documentation gaps when seeking EU project permits or financing, specifically the absence of IEC 62933-5-2 system-level thermal-runaway propagation test data and UL 9540A fire-spread data. Manufacturers targeting EU markets should commission supplementary testing to these standards. This is not legal advice; verify current harmonisation status and applicable national requirements with a qualified EU certifier.

Grid Connection Requirements for BESS Power Conversion System (PCS / Storage Inverter) In China, grid-connected storage inverters (PCS) are governed primarily by GB/T 34120-2023 (Technical Requirements for Power Conversion System of Electrochemical Energy Storage System), which superseded GB/T 34120-2017. The 2023 revision extended the AC output voltage upper limit to 35 kV, added fault ride-through (LVRT/HVRT) and primary frequency response requirements, and updated product classification. GB/T 19964-2012 (Technical Requirements for Photovoltaic Power Station Connected to Power System) is sometimes referenced for inverter grid-connection behaviour. The National Energy Administration (NEA) and grid companies (State Grid / Southern Grid) also issue enterprise standards (Q/GDW series) for energy storage grid connection.GB/T 34120-2023 — Technical Requirements for Power Conversion System of Electrochemical Energy Storage System (SAMR/SAC; supersedes GB/T 34120-2017; recommended national standard)

Q/GDW 1564-2014 (State Grid enterprise standard — current supersession status not publicly confirmable; verify with State Grid or SAC for any post-2020 revision)		 BESS storage inverters (PCS) connecting to EU grids must comply with EN 50549-1 (low voltage, ≤16 A/phase) or EN 50549-2 (medium voltage), which specify requirements for generating plants up to 75 kVA and above connected in parallel with the public distribution network, including voltage/frequency ride-through, reactive power capability, anti-islanding, and reconnection limits. Additionally, national grid codes apply depending on the member state: VDE-AR-N 4105 (Germany, LV) and VDE-AR-N 4110 (Germany, MV/HV), Engineering Recommendation G99 (Great Britain), among others. At the EU level, Commission Regulation (EU) 2016/631 (Requirements for Generators, RfG) sets binding requirements for power-generating modules above the thresholds defined by each member state, covering fault ride-through, frequency response, and reactive power exchange.EN 50549-1:2019 (CENELEC)

PCS units exported from China must be re-tested and re-certified to EN 50549-1 or EN 50549-2 by a recognised test laboratory (typically accredited under EA/DAkkS/UKAS), and must satisfy the applicable national grid code in each target member state. The EU RfG Regulation (2016/631) is directly applicable law in EU member states; Chinese type-test reports against GB/T 34120 are not substitutable. Key technical gaps include different voltage/frequency ride-through profiles, reactive power Q(U) curves, reconnection delay settings, and communication protocol requirements (IEC 61850 or utility-specific vs. Chinese Modbus/CAN conventions).[INFORMATIONAL ONLY] Chinese PCS / storage inverters certified only to GB/T 34120 are NOT compliant for EU grid connection.

CE Marking — LVD, EMC and Battery Regulation Conformity No direct equivalent. The China Compulsory Certification (CCC) scheme — administered by CNCA/CQC — covers certain electrical products for the domestic market but does not extend to stationary BESS in an equivalent scope to EU CE marking. Chinese BESS products intended for the domestic market may comply with GB/T 36558 and GB/T 34131; these do not confer EU market access. CCC certification is not a substitute for CE marking under LVD, EMC, or the EU Battery Regulation.CCC — administered under Regulation on Compulsory Product Certification (CNCA)

The CE mark is affixed by the manufacturer or importer after completing conformity assessment (typically Module A self-declaration for LVD/EMC; specific assessment routes under Regulation 2023/1542 depend on battery category and performance class). The exact conformity assessment module requirements under Regulation 2023/1542 for stationary BESS are subject to implementing acts that had not yet been fully adopted as of mid-2026; manufacturers should monitor EUR-Lex for publication of the relevant implementing acts before finalising their conformity assessment approach.Directive 2014/35/EU (LVD)

EU Declaration of Conformity (DoC) and Technical Documentation File Under the CCC scheme, Chinese manufacturers submit a test report and product samples to a designated certification body (e.g. CQC); a CCC certificate is issued upon approval. There is no requirement to draft a self-signed declaration of conformity or maintain a technical file in the EU sense. For export, some manufacturers voluntarily prepare a factory Declaration of Conformity for EU buyers, but this is not a Chinese regulatory obligation.

CNCA CCC implementation rules (product-category-specific)
GB/T 36558-2022 (supporting technical standard for BESS)		 Before affixing the CE mark, the responsible economic operator (manufacturer or EU-based authorised representative) must draw up an EU Declaration of Conformity (DoC) and compile a technical documentation file. The DoC must identify the product, list the applicable legislation and harmonised standards applied, identify the signatory, and be kept available for 10 years after the last product is placed on the market. The technical file must include design drawings, risk assessment, test reports, and quality procedures. Under Regulation 2023/1542, additional documentation obligations apply — notably the Battery Passport (Art. 77): from 18 February 2027, each LMT battery, each industrial battery with a capacity above 2 kWh, and each EV battery placed on the EU market must have a battery passport. The technical data-attribute specifications for the Battery Passport are subject to delegated acts that had not yet been published in the Official Journal as of mid-2026; manufacturers should monitor EUR-Lex and the Battery Pass consortium for updates ahead of the 2027 obligation date.Directive 2014/35/EU (LVD) — Art. 7, Annex III (DoC content), Annex IV (technical documentation)

Regulation (EU) 2023/1542 — Art. 18 (technical documentation), Art. 17 (EU declaration of conformity), Art. 77–78 (battery passport)		 Chinese manufacturers exporting BESS to the EU must prepare an EU-compliant DoC and technical file — neither exists as a domestic regulatory output. This requires assembling EU-specific test reports (harmonised standards), a risk assessment aligned to EU directives, and a declaration signed by an EU-recognised responsible person. The forthcoming battery passport obligation under Regulation 2023/1542 will add a further digital documentation layer with no Chinese precedent.Gap identified. EU DoC and technical file must be created from scratch for BESS exports to the EU; Chinese domestic CCC documentation does not satisfy this obligation. Battery passport readiness should be monitored.

Economic Operator / Authorised Representative, WEEE and Battery Producer Registration No equivalent obligation. Chinese manufacturers are not required by domestic regulation to appoint an EU authorised representative, register with EU producer schemes, or participate in EU take-back programs. China has a domestic extended producer responsibility (EPR) framework under the Management Measures for the Recovery and Disposal of Waste Electrical and Electronic Products (2016), but this applies only within China and covers different product categories. There is no Chinese equivalent to WEEE producer registration in EU member states or to the Battery Regulation producer register.Management Measures for the Recovery and Disposal of Waste Electrical and Electronic Products (State Council, 2011, amended 2016) — domestic EPR only
No equivalent to EU Regulation 2019/1020 authorised representative requirement		 Regulation (EU) 2019/1020 on market surveillance requires that products placed on the EU market have an identifiable responsible economic operator established in the EU — either the manufacturer (if EU-based), an importer, or a mandated authorised representative. This responsible person must be identified on the product or packaging and holds the technical file. Separately, the WEEE Directive (2012/19/EU) and Battery Regulation (2023/1542, Art. 56–61) require producers — including importers and authorised representatives acting as producers — to register with national producer registers and participate in take-back / collection schemes in each EU member state where products are sold. Stationary BESS products fall within the scope of the Battery Regulation as industrial batteries; the detailed producer registration procedures are implemented at member-state level and some procedural specifics remain subject to implementing acts still in development as of mid-2026 — verify the latest position with the relevant national competent authority in each target member state.Regulation (EU) 2019/1020 — Art. 4 (responsible economic operator), Art. 5 (tasks of authorised representative)

They must also register as producers — or ensure their EU importer/representative registers — under national WEEE registers and the Battery Regulation producer register in every EU member state of sale. These obligations are fully absent from the Chinese domestic compliance framework and represent a significant market-entry structural gap.Gap identified.

Lithium-Ion Cell and Battery Safety for Industrial Applications GB/T 36276-2023 (Electric Energy Storage Lithium-Ion Batteries) is a recommended Chinese national standard for lithium-ion batteries used in power energy storage systems. It specifies safety performance requirements including electrical, mechanical, environmental, and abuse tests for cells and battery packs, but its GB/T status means it is not itself the compulsory national requirement. China's compulsory cell and battery safety standard for electric energy storage is GB 44240-2024. Testing expectations may still reference GB/T 36276 in projects or procurement, but mandatory-status conclusions should be based on GB 44240-2024 and the applicable regulator or grid-operator requirements.GB/T 36276-2023 — recommended national standard for electric energy storage lithium-ion batteries
GB 44240-2024 — compulsory safety requirement for lithium-ion cells and batteries for electric energy storage		 EN IEC 62619:2022 sets safety requirements for secondary lithium cells and batteries used in industrial applications, including BESS. It covers abuse testing (overcharge, over-discharge, short-circuit, thermal, crush), BMS requirements, and marking.

Battery Energy Storage System (BESS) Safety — System Level GB/T 36558-2022 (General Technical Requirements for Electric Energy Storage Systems Connected to Power Systems) specifies system-level technical and safety requirements for grid-connected BESS in China, including electrical performance, protection, communication, and safety functions. It is a recommended (non-mandatory) national standard but is referenced in grid-connection agreements with State Grid and China Southern Power Grid, making it effectively mandatory for grid-connected projects. As of mid-2026, no Chinese national standard contains thermal runaway propagation prevention test requirements directly equivalent to IEC 62933-5-2 Annex B; this gap is a recognised regulatory difference between the Chinese and EU frameworks.GB/T 36558-2022

Ed 2.0 remains in development and does not supersede the 2020 edition for this dataset. EN IEC 62040 series covers UPS and power conversion safety. Under EU law, compliance with the essential safety requirements of LVD 2014/35/EU and Battery Regulation (EU) 2023/1542 is mandatory; harmonised standards such as IEC/EN 62933-5-2 are voluntary and provide a presumption of conformity only when their references are published in the EU Official Journal (OJ). If IEC/EN 62933-5-2 is not OJ-listed at the time of assessment, it serves as technical evidence supporting conformity but does not automatically grant presumption. Manufacturers must verify current OJ listing status before relying on presumption of conformity.

For BESS, this covers the battery system, inverter/PCS, switchgear, and enclosures. The manufacturer must prepare a technical file, conduct conformity assessment (typically internal production control for harmonised-standard-covered products), and issue an EU Declaration of Conformity. Harmonised standards EN IEC 62619, EN IEC 63056, and IEC 62933-5-2 provide presumption of conformity with LVD essential safety requirements.LVD 2014/35/EU

IEC 62933-5-2:2020		 China's project-approval and grid-operator review model does not produce the product-level EU DoC and technical file required by LVD 2014/35/EU. Chinese exporters must appoint an EU Authorised Representative, compile an LVD-compliant technical file (risk assessment, test reports to harmonised standards, instructions), and self-declare or engage a notified body. No bilateral mutual recognition agreement (MRA) covers electrical safety between China and the EU for BESS products, so Chinese test reports must be supplemented or replaced by tests at EU-recognised (ILAC MRA) laboratories.[INFORMATIONAL] Chinese safety approvals (NEA project approval, grid-operator certificates, GB 36276 test reports) do not constitute LVD compliance. EU market access requires a product-level EU Declaration of Conformity, an LVD-compliant technical file, CE marking, and an appointed EU Authorised Representative.

Lithium Battery Transport Safety Testing — UN 38.3 China applies the same UN 38.3 test standard for export shipments and mirrors it in national regulations. For road transport, the standard GB 15599 (Safety requirements for transport of lithium batteries by road) references UN 38.3. China's GB 38031-2020 (Electric vehicles traction battery safety requirements) mandates UN 38.3-equivalent tests for vehicle-grade cells but is not a transport regulation. Export customs and the Ministry of Transport require a valid UN 38.3 test report and dangerous goods declaration (危险货物运输申报) per JT/T 617 (road) and IMDG/IATA rules for maritime/air. The Civil Aviation Administration of China (CAAC) DGR follows IATA. The exact current edition of GB 15599 and any amendments issued after 2024 are not publicly confirmable via open sources — verify the current edition via SAC or the Ministry of Transport before relying on it.UN Manual of Tests and Criteria, Section 38.3 (adopted for export)

CAAC Dangerous Goods Regulations (aligned with IATA DGR)		 All lithium cells and batteries (including BESS modules) shipped internationally must pass the UN Manual of Tests and Criteria, Part III, Section 38.3 test series (T1–T8: altitude simulation, thermal, vibration, shock, external short circuit, impact/crush, overcharge, forced discharge). The current edition is Rev.8 (2023) with Amendment 1 (2025) (ST/SG/AC.10/11/Rev.8). A UN 38.3 test summary or full test report must accompany each shipment. The UN number classification is UN 3480 (lithium-ion batteries, packed alone) or UN 3481 (lithium-ion batteries contained in or packed with equipment). Transport by road in Europe is governed by ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road); by sea by IMDG Code; by air by IATA Dangerous Goods Regulations.UN Manual of Tests and Criteria, Part III, Section 38.3 (ST/SG/AC.10/11/Rev.8 (2023) and Amendment 1 (2025))

IATA Dangerous Goods Regulations (DGR) 65th Edition 2024 — Special Provisions A88, A99, A154, A164, A183, A201, A206		 Both EU/international and China require UN 38.3 testing, so the test protocol itself is not a gap. The gaps lie in documentation and enforcement: (1) EU/ADR strictly enforces the UN 38.3 test summary requirement at the shipper level — the summary (not merely a certificate) must be available on request for every consignment, including cell-level data; CN exporters sometimes hold only a product certificate without the full T1–T8 summary. (2) ADR 2025 introduces updated provisions on state-of-charge (SOC ≤30%) limits and packaging requirements for large-format BESS cells that may not yet be reflected in all CN factory SOPs. (3) IATA PI 965/966/967 Section II thresholds (Wh limits per package) are strictly enforced by EU carriers; Chinese air-freight agents occasionally mis-classify oversized BESS modules. (4) EU member states may require additional national derogations or consignment notifications for BESS transported by road above certain energy thresholds — CN has no equivalent sub-national layer.Informational only. A Chinese BESS exporter shipping to the EU must hold a valid UN 38.3 test report (T1–T8 summary) for every cell/module type, classify under UN 3480 or UN 3481, comply with ADR (road), IMDG (sea), or IATA (air) packaging and documentation requirements, and ensure SOC does not exceed 30% where required. The test framework is shared with China, but EU enforcement of documentation, SOC limits, and packaging is stricter. Consult a certified dangerous goods safety adviser (DGSA) before first shipment.

Dangerous Goods Classification, Packaging & Documentation — ADR / IMDG / IATA China's export dangerous goods documentation requirements align with IMDG and IATA for sea and air freight. For road within China, JT/T 617.1-2018 (Classification of dangerous goods for road transport) and JT/T 617.4-2018 (Packaging and labelling) apply. The China Civil Aviation Administration (CAAC) DGR mirrors IATA PI 965/966/967. Export customs (GACC) requires a dangerous goods inspection certificate (危险品检验证书) for certain battery shipments. Packaging must meet GB 12463 (General technical requirements for dangerous goods transport packaging) for domestic road, or UN-certified packaging for export. The precise scope of GACC inspection certificate requirements for BESS exports — including whether they apply to all consignments or only above specified Wh or weight thresholds — is subject to GACC administrative announcements that change periodically; verify the current requirements directly with a licensed Chinese customs broker or GACC before shipment.JT/T 617.1-2018 — Classification of dangerous goods for road transport (China)

GACC dangerous goods inspection requirements for battery exports (exact threshold and scope subject to periodic GACC administrative announcements — verify with a licensed Chinese customs broker before shipment)		 Beyond UN 38.3 testing, EU/international transport law requires: (a) correct UN number (UN 3480/3481) and packing group on all shipping documents; (b) compliant outer packaging (UN-certified for full lithium batteries, or Section II packaging for consumer-type); (c) shipper's Declaration for Dangerous Goods (DGD) for air, or Dangerous Goods Transport Document for road/sea; (d) emergency response information (e.g., ERG, MSDS/SDS); (e) placarding and labelling of packages and vehicles (Class 9 hazard label, lithium battery mark). ADR Chapter 3.3 Special Provision 377 and ADR 2.2.9.1 govern large-format batteries. State-of-charge (SOC) limits apply: ≤30% for air (IATA PI 965 Section IB), and in certain ADR provisions.ADR 2025 — Chapter 3.3 SP 377, SP 188, SP 230; Section 2.2.9.1; Packing Instructions P903, P908

Regulation (EC) No 1272/2008 (CLP) — for SDS/labelling obligations where applicable		 Key gaps for a Chinese BESS exporter shipping to the EU: (1) EU ADR requires a Dangerous Goods Safety Adviser (DGSA) to be appointed by the carrier — this role is not always mirrored in CN export logistics chains. (2) EU carriers and ports strictly enforce the Class 9 lithium battery mark (IEC 62133-format label with watt-hour rating) on each package outer; CN factories may use older label formats. (3) ADR 2025 and IMDG 41-22 updated special provisions for large-energy battery consignments (>500 kg net per transport unit in some configurations) with additional notification requirements — these may not yet be in CN forwarder checklists. (4) Some EU member states (e.g., Germany, France) require prior notification or route approval for large BESS road shipments above defined energy thresholds — CN has no equivalent. (5) Multimodal shipments (sea + road) require re-documentation at EU port of entry to ADR — a step sometimes missed by CN-origin shipments prepared only to IMDG.Informational only. Shipping BESS from China to the EU requires a full dangerous goods compliance programme: UN 38.3 test summaries, correct UN number classification, UN-certified packaging, mode-specific documentation (ADR/IMDG/IATA), Class 9 labels, SOC management, and appointment of a DGSA for EU road legs. Chinese exporters accustomed to domestic JT/T 617 or IMDG-only workflows must add ADR re-documentation at EU entry ports for multimodal shipments. Engage a certified DGSA and a specialist dangerous goods freight forwarder before first shipment.
