Carbon Footprint Declaration — Sodium-Ion Industrial Batteries No mandatory Chinese equivalent for sodium-ion or any battery chemistry. China's voluntary product carbon footprint standard GB/T 24067-2024 (aligned with ISO 14067) exists but carries no binding enforcement. Provincial pilot carbon-labelling schemes are patchwork and do not cover batteries specifically. The Chinese sodium-ion battery sector has no industry-specific CFD guidance as of 2026-06-12.GB/T 24067-2024 (voluntary — product carbon footprint quantification, not battery-specific)
No binding CN battery CFD regulation as of 2026-06-12		 Regulation (EU) 2023/1542 applies to ALL battery chemistries without exception, explicitly including sodium-ion. Industrial batteries with a capacity of 2 kWh or above — a category that covers virtually all stationary Na-ion BESS units — are subject to a carbon footprint declaration (CFD) obligation calculated per lifecycle stage using a harmonised EU methodology once the applicable delegated-act timing is in force. The Regulation sets the application date as 18 February 2026 or 18 months after the entry into force of the relevant delegated act, whichever is later. The calculation methodology and performance classes are defined via delegated acts adopted by the European Commission. The JRC published the technical methodology basis for industrial batteries (JRC Report JRC141282, Rules for the Calculation of the Carbon Footprint of Industrial Batteries without External Storage, April 2025), but as of mid-2026 the formal Commission delegated act establishing the binding CFD calculation methodology for industrial batteries had not been published in the Official Journal — meaning the 18-month clock had not yet started and the effective date may be later than 18 February 2026.Regulation (EU) 2023/1542, Articles 7 and 8 (carbon footprint — applies to all chemistries including sodium-ion)
Regulation (EU) 2023/1542, Article 2 (scope — no chemistry exclusions)
ISO 14067 (referenced lifecycle GHG methodology basis)
Delegated act on CFD calculation rules for industrial batteries — JRC methodology base (JRC141282, April 2025) published; formal Commission delegated act not yet adopted or published in OJ as of mid-2026; effective date therefore remains deferred beyond 18 February 2026		 Chinese Na-ion BESS manufacturers face no domestic CFD obligation, while EU law creates a chemistry-neutral CFD obligation for industrial batteries 2 kWh and above once the relevant delegated act and application date are in force. Because the industrial-battery calculation-methodology delegated act had not been published in the OJ as of mid-2026, the practical application date appears deferred beyond 18 February 2026. Establishing a lifecycle GHG inventory (cradle-to-gate at minimum), engaging an accredited third-party verifier, and integrating EU-format CFD declarations into product documentation remains a significant upcoming compliance burden for which many Chinese Na-ion producers are likely unprepared.High gap with timing uncertainty. Na-ion chemistry receives no exemption from the EU Battery Regulation, but the industrial-battery CFD calculation-methodology delegated act had not been published in the OJ as of mid-2026, so manufacturers should treat CFD readiness as an imminent compliance programme rather than assume current non-compliance solely from the 18 February 2026 date.

CE Marking, Conformity Assessment & Performance Standards — Sodium-Ion China has no equivalent to the EU Battery Regulation CE conformity regime for sodium-ion batteries. China published GB/T 44265-2024 (Electrical energy storage power station — Technical specifications for sodium-ion batteries), effective 1 March 2025: this is the first dedicated Chinese national standard specifically for Na-ion stationary storage. The China Quality Certification Centre (CQC) introduced a voluntary certification programme for Na-ion stationary storage batteries under CQC13-464292-2025, aligned with GB/T 44265-2024. CCC (China Compulsory Certification) does not currently list stationary Na-ion batteries as a mandatory category. Some Chinese manufacturers also voluntarily test against IEC 62619.GB/T 44265-2024 (sodium-ion batteries for electrical energy storage power stations — first dedicated CN Na-ion stationary storage standard, effective 1 March 2025)

IEC 62619:2022 (voluntary; secondary cells and batteries — safety requirements, adaptable to Na-ion)
CCC system — Na-ion stationary batteries not listed as mandatory CCC category as of mid-2026		 All batteries placed on the EU market under Regulation (EU) 2023/1542 must bear CE marking, supported by a completed conformity assessment and an EU Declaration of Conformity (DoC). Sodium-ion batteries are explicitly within scope — the Regulation contains no chemistry-based exemptions. Industrial batteries (including Na-ion BESS) must meet electrochemical performance and durability requirements set out in Article 10 and Annex IV: minimum capacity retention, energy efficiency, and cycle life benchmarks. The specific minimum threshold values for industrial batteries are to be defined by delegated acts; the Commission's statutory deadline for adopting performance class thresholds for industrial batteries is 18 August 2026. No Na-ion-specific performance threshold delegated act has been published in the OJ as of mid-2026; the general industrial battery delegated act covering all chemistries (including Na-ion) is expected by that date. Conformity assessment for industrial batteries may be conducted via internal control (Annex VIII Module A); third-party notified-body involvement is required where harmonised standards do not exist. No harmonised EN standard under the Battery Regulation has been published in the OJ as of mid-2026 — CEN/CENELEC work under Mandate M/579 (amended) is ongoing.Regulation (EU) 2023/1542, Articles 10 and 18-24 (performance, CE marking, conformity assessment)
Regulation (EU) 2023/1542, Annexes IV, VIII, IX
Regulation (EU) 2023/1542, Article 2 (chemistry-neutral scope)
Harmonised EN standards under the Battery Regulation — CEN/CENELEC working under Mandate M/579 (amended); no harmonised standard yet listed in OJ as of mid-2026; once published in OJ they will confer presumption of conformity
Delegated acts on performance thresholds for industrial batteries — Commission statutory deadline 18 August 2026; not yet adopted as of mid-2026		 Sodium-ion is a chemistry for which harmonised EU standards under the Battery Regulation are still being developed. This creates a double compliance challenge: manufacturers must satisfy the Regulation's CE marking and conformity-assessment obligations at a time when harmonised test standards do not yet exist; harmonised standards would be voluntary presumption-of-conformity routes once cited in the OJ, and alternative evidence may be used where justified. Simultaneously, no Chinese domestic standard or certification programme mirrors the EU performance-and-durability or conformity-assessment framework for Na-ion BESS, meaning exporters cannot leverage domestic certification as a direct stepping stone.High gap with additional uncertainty for Na-ion. The chemistry-neutral scope of the Regulation means Na-ion is fully subject to CE marking and performance requirements, while harmonised standards that may provide a voluntary presumption of conformity are still under development. Chinese Na-ion BESS exporters should engage EU notified bodies or conformity-assessment advisers early. Informational only — seek qualified legal and technical advice.

Supply Chain Due Diligence, Labelling & Battery Passport — Sodium-Ion No mandatory Chinese equivalent for any of the three obligations. China has voluntary responsible sourcing initiatives (e.g. CAAM Responsible Battery Initiative, CATL ESG disclosures) but no binding domestic law requires battery supply chain due diligence disclosure. Chinese product labelling under GB standards covers basic safety information but not the EU-format chemistry identifier, recycled-content share, or QR-linked digital traceability. No Battery Passport or equivalent digital product record obligation exists in Chinese regulation. Sodium-ion batteries in particular have no dedicated Chinese labelling or traceability framework as of 2026-06-12.No binding CN due diligence, labelling-equivalence, or Battery Passport obligation as of 2026-06-12
CAAM Responsible Battery Initiative (voluntary)
GB/T 36276-2023 (basic product marking — no QR traceability or recycled-content fields)
No CN Battery Passport equivalent		 Three interrelated obligations under Regulation (EU) 2023/1542 apply to Na-ion industrial batteries: (1) Supply chain due diligence (Article 48): economic operators above turnover thresholds placing industrial batteries on the EU market must maintain an OECD-aligned due diligence policy covering upstream sourcing of cobalt, natural graphite, lithium, and nickel — the four regulated minerals. Sodium-ion batteries typically use hard carbon anodes (sourced from biomass or fossil precursors) rather than lithium; however, some cathode chemistries may still use regulated minerals. The due diligence obligation was postponed from 18 August 2025 to 18 August 2027 by Regulation (EU) 2025/1561 (OJ L 2025/1561, confirmed). (2) Labelling (Article 13): all batteries must carry prescribed labels including capacity, chemistry identifier, hazard symbols, recycled-content share, and a QR code; basic labelling mandatory from 18 August 2025, extended labelling from 18 August 2026 or 18 months after the relevant implementing act, whichever is later. (3) Battery Passport (Article 77): industrial batteries 2 kWh and above must have a digital Battery Passport accessible via QR code containing lifecycle, carbon footprint, state-of-health, and supply chain data, mandatory from 18 February 2027.Regulation (EU) 2023/1542, Article 48 (supply chain due diligence)

Delegated acts on Battery Passport data attributes — not yet adopted as of mid-2026; Commission guidelines on operational implementation were expected by 18 August 2025 but formal delegated act adoption remains pending; the 18 February 2027 Battery Passport mandatory date is contingent on these acts being in force		 Na-ion BESS exporters to the EU face three concurrent compliance gaps with no domestic Chinese parallel. The due diligence gap is partially mitigated by Na-ion's reduced dependence on lithium and cobalt — key regulated minerals — but cathode-material sourcing must still be audited and disclosed. The labelling and Battery Passport gaps are chemistry-neutral: all industrial batteries above 2 kWh, including Na-ion, must implement EU-format QR labelling by mid-2026 and a full digital Battery Passport by February 2027. Most Chinese Na-ion manufacturers are at early stages of EU market entry and have typically not invested in the required data infrastructure.Critical multi-obligation gap. Labelling obligations are already in force; Battery Passport and due diligence deadlines are approaching. Na-ion's lower critical-mineral content may ease due diligence somewhat, but labelling and passport obligations are chemistry-neutral and fully applicable. Chinese Na-ion BESS exporters are structurally unprepared for this regime. Informational only — seek qualified legal and technical advice.

CE Marking — LVD / EMC Directives and Battery Regulation (EU) 2023/1542 Conformity No direct equivalent. China Compulsory Certification (CCC) — administered by CNCA / CQC — covers certain electrical products for the domestic Chinese market but does not extend to stationary Na-ion BESS in a scope equivalent to EU CE marking. Chinese Na-ion BESS products for the domestic market may reference GB/T 36558 (general technical requirements for electrochemical energy storage systems) and GB/T 44265-2024 (sodium-ion battery technical specifications for stationary storage, effective March 2025); these standards do not confer EU market access. The CQC voluntary certification programme (CQC13-464292-2025) aligned with GB/T 44265-2024 is available from 2025 but is not a CCC mandatory scheme. Na-ion stationary batteries are not listed as a mandatory CCC product category as of mid-2026. CCC is not a substitute for CE marking under LVD, EMC Directive, or Regulation 2023/1542.CCC scheme — administered under Regulations on Compulsory Product Certification (State Council Order No. 117, 2001, as amended)
GB/T 36558-2022 (general technical requirements for electrochemical energy storage systems)

GB/T 17626 series (EMC, aligned with IEC 61000)		 Sodium-ion (Na-ion) battery energy storage systems placed on the EU market must bear the CE mark, demonstrating conformity with all applicable EU legislation. At minimum this covers the Low Voltage Directive (LVD 2014/35/EU), the EMC Directive (2014/30/EU), and the EU Battery Regulation (Regulation (EU) 2023/1542). Regulation 2023/1542 is chemistry-neutral and explicitly covers all rechargeable industrial and stationary batteries regardless of electrochemical technology; Na-ion cells fall within its scope. CE conformity assessment for LVD and EMC is typically performed via Module A (internal production control with self-declaration). Conformity assessment routes under Regulation 2023/1542 depend on battery category and applicable performance class; the performance threshold delegated act for industrial batteries is due by 18 August 2026 (statutory Commission deadline) but has not been adopted as of mid-2026 — no Na-ion-specific carve-out is expected. An EU Declaration of Conformity (DoC) and technical documentation file must be compiled before the CE mark is affixed.Directive 2014/35/EU (Low Voltage Directive, LVD)

EN 61000-6-2 / EN 61000-6-4 (voluntary harmonised EMC standards that may confer presumption of conformity when correctly applied)		 Chinese Na-ion BESS manufacturers must obtain CE marking under LVD, EMC Directive, and Regulation (EU) 2023/1542 before EU market entry. The compliance gap is structurally identical to Li-ion BESS: CCC satisfies none of these requirements, and separate EU-specific conformity assessment, technical documentation, and self-declaration must be completed. Na-ion technology may face an additional gap where voluntary harmonised test standards under IEC / CENELEC specific to Na-ion chemistry are still emerging, potentially requiring alternative evidence or deviation justification in the technical file. Manufacturers should monitor EUR-Lex for implementing acts under Regulation 2023/1542 that define final performance thresholds.Gap identified. CE marking under LVD, EMC Directive, and Regulation (EU) 2023/1542 is mandatory for EU market access; CCC provides no equivalence. The gap is structurally the same as for Li-ion BESS, with a potential additional gap because Na-ion-specific harmonised standards that could provide voluntary presumption of conformity are still emerging.

Economic Operator / Authorised Representative (Reg 2019/1020) — WEEE and Battery Regulation Producer Registration and Take-back No equivalent obligation exists under Chinese domestic regulation. Chinese manufacturers are not required to appoint an EU authorised representative, register with EU national battery or WEEE producer registers, or fund EU take-back schemes. China maintains a domestic extended producer responsibility framework for waste electrical and electronic products under the Management Measures for the Recovery and Disposal of Waste Electrical and Electronic Products (State Council, 2011, amended 2016), but this applies solely within China and does not extend to the product categories or obligations under EU Regulation 2019/1020 or Regulation 2023/1542. There is no Chinese regulatory equivalent to EU producer registration in member states or to Battery Regulation take-back and collection obligations.Management Measures for the Recovery and Disposal of Waste Electrical and Electronic Products (State Council Order No. 551, 2011, amended 2016) — domestic EPR only, not equivalent to EU obligations
No Chinese equivalent to Regulation (EU) 2019/1020 authorised representative requirement
No Chinese equivalent to Regulation (EU) 2023/1542 producer registration and take-back obligations		 Regulation (EU) 2019/1020 on market surveillance and compliance of products requires that any product placed on the EU market has an identifiable responsible economic operator established within the EU. For a non-EU manufacturer this means appointing an EU-based authorised representative who holds the technical documentation, can cooperate with market surveillance authorities, and is identified on the product or its packaging. Separately, Regulation (EU) 2023/1542 (Battery Regulation, Art. 56-61) and the WEEE Directive (2012/19/EU, Art. 16-17) impose extended producer responsibility (EPR) obligations: manufacturers, importers, or their authorised representatives acting as producers must register with national battery and WEEE producer registers in each EU member state where products are placed on the market, and must participate in or fund take-back and collection schemes. Regulation 2023/1542 is chemistry-neutral; Na-ion batteries are within scope. The precise classification of stationary Na-ion BESS under Regulation 2023/1542 Art. 3 (industrial battery vs. stationary battery category) remains subject to implementing acts in development as of mid-2026; the distinction affects which specific EPR and performance requirements apply but does not affect whether the Regulation applies at all.Regulation (EU) 2019/1020 of the European Parliament and of the Council on market surveillance and compliance of products — Art. 4 (tasks of economic operators), Art. 5 (tasks of authorised representative)
Regulation (EU) 2023/1542 (Battery Regulation) — Art. 3 (definitions: industrial battery, stationary battery), Art. 56-61 (extended producer responsibility, registration, take-back and collection)
Directive 2012/19/EU (WEEE Directive) — Art. 16 (registration of producers), Art. 17 (reporting obligations)		 Chinese Na-ion BESS manufacturers without an EU establishment must appoint an EU authorised representative under Regulation 2019/1020 before EU market entry. They must also register as producers — or ensure their EU importer or representative registers — with national battery producer registers and WEEE registers in every EU member state where products are sold, and must participate in or fund take-back and collection arrangements under Regulation 2023/1542 and the WEEE Directive. The gap is structurally identical to the Li-ion BESS case: these obligations are entirely absent from the Chinese domestic compliance framework. Multi-country EPR registration and ongoing reporting duties represent a significant ongoing operational cost. Na-ion batteries may face definitional uncertainty under Regulation 2023/1542 Art. 3 (industrial vs. stationary battery category) pending implementing acts.Gap identified. Appointment of an EU authorised representative and producer registration under the Battery Regulation and WEEE Directive are mandatory structural requirements with no Chinese domestic equivalent. The gap is identical in nature to the Li-ion BESS case. Multi-country registration is required for multi-market EU sales.

Cell and Battery Safety Requirements — Secondary Lithium/Na-ion Cells and Batteries (Industrial Applications) GB/T 36276-2023 covers safety requirements for lithium-ion battery energy storage systems and is scoped to Li-ion only. China published GB/T 44265-2024 (Electrical energy storage power station — Technical specifications for sodium-ion battery), effective 1 March 2025: this is the first dedicated CN national standard for Na-ion stationary storage. It is a technical specification standard covering performance and some safety aspects at cell and system level for Na-ion BESS. The CQC voluntary certification programme CQC13-464292-2025, aligned with GB/T 44265-2024, is available from 2025. GB/T 42288-2022 addresses electrochemical energy storage station safety more broadly. No dedicated comprehensive Na-ion cell-safety standard equivalent to EN IEC 62619 exists in the CN framework; GB/T 44265-2024 covers the closest scope but is not a direct cell-safety standard.[object Object]
[object Object]
[object Object]		 EN IEC 62619:2022 specifies safety requirements for secondary lithium cells and batteries used in industrial applications, covering electrical, mechanical, environmental and safety abuse tests. Its scope title and text explicitly reference 'lithium' technology; the standard is largely test-method based, but Na-ion cells are not within the explicit scope of EN IEC 62619 — confirmation from CENELEC or an EU notified body is recommended before relying on this standard for Na-ion CE evidence. LVD 2014/35/EU imposes the mandatory legal safety obligations for covered electrical equipment; harmonised standards such as EN IEC 62619 are voluntary routes that may confer a presumption of conformity when correctly applied, and alternatives are allowed if the technical file demonstrates conformity with the Directive's safety objectives.[object Object]
[object Object]		 EN IEC 62619 was developed for lithium-cell chemistry and its title and scope explicitly reference 'lithium'; Na-ion cells are not within EN IEC 62619's explicit scope and CENELEC has not issued a corrigendum or scope extension for Na-ion. Exporters should obtain a written position from their chosen EU notified body on whether Na-ion cells can be tested under EN IEC 62619 with deviation justification, or whether a supplementary test protocol is needed. No harmonised EU standard specifically named for Na-ion cell safety exists yet. On the CN side, GB/T 44265-2024 (effective March 2025) covers Na-ion stationary storage as a technical specification standard, which partially closes the domestic standards gap but is not an equivalent to EN IEC 62619 as a comprehensive cell-safety standard.For informational purposes only. Na-ion cells exported from China to the EU as part of industrial ESS must meet the applicable EU legal safety obligations, including LVD 2014/35/EU where the voltage range is covered. EN IEC 62619 may be used only as a voluntary presumption-of-conformity route where its scope and deviations are accepted; it is not binding law and not an exclusive route. EN IEC 62619 explicitly scopes to 'lithium' cells, so Na-ion applicability should be resolved with an EU notified body or competent conformity-assessment adviser. No harmonised EU standard specifically covering Na-ion cell safety has been published. EUR-Lex (LVD 2014/35/EU); IEC webstore (EN IEC 62619)2026-06-12 · unverified
Energy Storage System Safety — Electrochemical ESS Safety Requirements (Chemistry-Agnostic) GB/T 34120-2017 covers general technical requirements for electrochemical energy storage systems and is chemistry-agnostic at the system level. GB/T 42288-2022 addresses safety requirements specifically for electrochemical energy storage stations, also applicable across chemistries. These are the closest CN system-level equivalents to IEC 62933-5-2. China published GB/T 44265-2024 (Electrical energy storage power station — Technical specifications for sodium-ion battery), effective 1 March 2025: this is the first dedicated Chinese national standard for Na-ion stationary ESS, covering technical specifications. It addresses performance and some safety aspects but is a technical specification standard rather than a comprehensive safety standard on the scale of IEC 62933-5-2. The CQC voluntary certification programme (CQC13-464292-2025) aligned with GB/T 44265-2024 became available in 2025.[object Object]
[object Object]
[object Object]		 IEC 62933-5-2:2025 (Ed. 2.0, published December 2025) (Electrical Energy Storage — Part 5-2: Safety requirements for grid-integrated electrochemical-based energy storage systems) supersedes the 2020 edition (Ed. 1.0). The standard's scope covers grid-connected electrochemical ESS across all chemistries. Ed. 2.0 explicitly lists lithium-ion, lead-acid, nickel, flow batteries, and lithium metal solid-state batteries and includes an 'other technologies' clause. Room-temperature sodium-ion is not explicitly named in the scope, but falls within the 'other technologies' clause — this is a strong basis for applicability, though confirmation with a notified body is still recommended before relying on IEC 62933-5-2 for Na-ion CE marking. The standard addresses system-level safety including thermal runaway, BMS requirements, fire protection, installation and O&M. In the EU, conformity may be demonstrated under LVD 2014/35/EU and the Battery Regulation (EU) 2023/1542 for stationary storage applications; IEC 62933-5-2's harmonised status under the Battery Regulation is not yet confirmed in the OJ.[object Object]
[object Object]
[object Object]		 IEC 62933-5-2 is chemistry-agnostic in scope, making it more directly applicable to Na-ion ESS than EN IEC 62619. However, Na-ion-specific test data (e.g., thermal runaway propagation characteristics, electrolyte composition hazards) may differ from Li-ion; the standard's test protocols may need supplementary validation for Na-ion systems. On the CN side, GB/T 44265-2024 (effective March 2025) is the first dedicated Na-ion ESS technical specification and narrows the standards gap: exporters can now point to a domestic Na-ion-specific standard, though it is a technical specification rather than a comprehensive safety standard on the scale of IEC 62933-5-2. The EU Battery Regulation (2023/1542) introduces additional due-diligence and documentation requirements (carbon footprint, supply chain) that apply to Na-ion batteries for stationary storage and are not mirrored in current CN standards.For informational purposes only. IEC 62933-5-2 is likely a relevant voluntary system-level safety standard for Na-ion ESS exported to the EU due to its chemistry-agnostic scope, but it is not itself the binding legal obligation or an exclusive route to conformity. Its harmonised status under EU Battery Regulation 2023/1542 and LVD 2014/35/EU should be verified with a notified body or conformity-assessment adviser. Na-ion-specific test data requirements may necessitate supplementary testing beyond standard Li-ion protocols. The EU Battery Regulation introduces additional obligations (carbon footprint declaration, supply-chain due diligence) not covered by IEC 62933-5-2 alone.

Transport Safety Testing — UN 38.3 (Na-ion scope confirmed) China applies the same UN 38.3 test standard for export shipments of sodium-ion batteries, as it does for lithium-ion. Domestically, road transport of dangerous goods is governed by JT/T 617; the Civil Aviation Administration of China (CAAC) DGR follows IATA. China does not yet have a separate national standard for sodium-ion battery transport classification equivalent to UN 3551/3552 — exporters are expected to apply the international UN numbers for cross-border shipments. GB 38031-2025 (electric vehicle battery safety) covers cell-level safety testing for Na-ion traction batteries but is not a transport regulation. No confirmed 2025 CN guidance specifically updating domestic road or sea transport classification for Na-ion to reference UN 3551/3552 has been identified; CN exporters use the international entries directly.UN Manual of Tests and Criteria, Section 38.3 (adopted for export)

IATA Dangerous Goods Regulations — applicable packing instructions for sodium-ion batteries		 The test protocol (UN 38.3) is the same for both Na-ion and Li-ion — no gap in testing requirements. The key gap is awareness and documentation readiness: sodium-ion is a newer chemistry and fewer Chinese manufacturers have completed full UN 38.3 test series for Na-ion cells specifically. EU/ADR enforcement requires cell-type-specific test summaries; a Li-ion UN 38.3 report cannot be reused for Na-ion cells. Exporters must commission separate Na-ion UN 38.3 testing before first EU shipment. No CN authority confirmation of blanket equivalency between GB-level Na-ion cell tests and UN 38.3 T1-T8 for export documentation purposes has been identified; standard practice is to conduct full UN 38.3 testing at an accredited laboratory.Informational only.

Chinese manufacturers exporting Na-ion batteries to the EU adopt UN 3551 or UN 3552 directly on shipping documents. Domestically, JT/T 617 covers dangerous goods road classification; no confirmed official Chinese update explicitly incorporating Na-ion as UN 3551/3552 has been identified as of mid-2026. The deeply discharged or 0 V shipping capability is a chemistry-inherent property applicable globally regardless of CN or EU classification regime, and also codified under ADR 2025 SP 400.UN Model Regulations, 23rd revised edition — UN 3551 / UN 3552 (applicable for CN export documentation)
JT/T 617 — Regulations for road transport of dangerous goods (China) — no confirmed update explicitly incorporating Na-ion entries as of mid-2026; exporters use international UN 3551/3552 classification directly on cross-border documents
CAAC Dangerous Goods Regulations (aligned with IATA DGR)		 The UN Model Regulations 23rd revised edition (published August 2023; harmonised into ADR 2025 effective 1 January 2025 with a 12-month transition period to 31 December 2025, and into IMDG Code Amendment 42-24) introduced two new dedicated UN entries for sodium-ion batteries with organic electrolyte: UN 3551 (sodium-ion batteries with organic electrolyte, standalone) and UN 3552 (sodium-ion batteries contained in equipment or packed with equipment, with organic electrolyte). Both are classified as Class 9 — Miscellaneous Dangerous Goods, classification code M4, label 9A, no packing group, with ADR special provisions including 188, 230, 310, 348, 376, 377, 400, 401, 636 and 677. Previously, Na-ion batteries were often handled under lithium-ion UN entries (UN 3480/3481), which caused classification ambiguity; the new entries remove that ambiguity once the applicable transport regime has adopted them. A key logistics and safety advantage of sodium-ion over lithium-ion is that Na-ion cells can be transported in a deeply discharged or fully discharged state (including 0 V) because Na-ion typically uses aluminium rather than copper as the negative electrode current collector, avoiding the copper-dissolution risk seen in over-discharged Li-ion cells. ADR 2025 Special Provision 400 codifies a related but distinct exemption: sodium-ion cells and batteries are exempt from other ADR provisions if short-circuited so that the cell/battery contains no electrical energy, the short-circuiting is easily verifiable (e.g. busbar between terminals), and other packaging conditions under 2.2.9.1.7.2 are met. This SP 400 exemption is a formally codified ADR 2025 provision specific to Na-ion; broader 0 V shipping claims should be tied to the actual cell design, test evidence, and applicable modal rules.UN Model Regulations on the Transport of Dangerous Goods, 23rd revised edition (2023) — UN 3551 / UN 3552 (sodium-ion batteries with organic electrolyte, standalone and contained in/packed with equipment; Class 9, code M4, label 9A, no packing group)
ADR 2025 — European Agreement concerning the International Carriage of Dangerous Goods by Road (effective 1 January 2025; 12-month transition period to 31 December 2025) — UN 3551, UN 3552, Special Provisions 188, 230, 310, 348, 376, 377, 400, 401, 636, 677; SP 400 codifies short-circuit/no-electrical-energy exemption for Na-ion
IMDG Code Amendment 42-24 — harmonised with UN Model Regs 23rd ed., incorporating UN 3551 / UN 3552
UN Manual of Tests and Criteria, Part III, Section 38.3 — applicable to Na-ion under UN 3551/3552		 The new UN 3551/3552 entries (ADR 2025 / UN Model Regs 23rd ed.) reduce misclassification risk for Na-ion batteries with organic electrolyte once adopted by the applicable transport regime. The deeply discharged or 0 V transport capability is a chemistry advantage, but the legal exemption should be stated precisely: ADR 2025 Special Provision 400 exempts sodium-ion cells and batteries from other ADR requirements only where the cell/battery is short-circuited so it contains no electrical energy, the short-circuiting is easily verifiable (e.g. busbar between terminals), and the packaging conditions are met. The underlying chemistry reason — Na-ion typically uses aluminium rather than copper as the negative electrode current collector, avoiding copper dissolution at very low voltages — supports the safety rationale, but exporters should not claim a blanket modal exemption beyond SP 400 and the applicable ADR/IMDG/ICAO-IATA provisions.Informational only. UN 3551 and UN 3552 are adopted in ADR 2025 (Class 9, code M4, label 9A, special provisions including 188, 230, 310, 348, 376, 377, 400, 401, 636 and 677) for sodium-ion batteries with organic electrolyte. Na-ion BESS exporters to the EU must classify under UN 3551 or UN 3552 where applicable, complete UN 38.3 testing for Na-ion cells specifically, and may use ADR 2025 Special Provision 400 only when its short-circuit/no-electrical-energy conditions are met.
