Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline United Kingdom (UKCA / CE for Great Britain) Gap / action Source + verification date
UK and EU Battery Regulation Workstreams — Substance Limits, Labelling, EPR and NI / CE Exposure China has domestic battery recycling and product-safety frameworks, but no UK-equivalent producer registration, UK crossed-out wheeled-bin labelling duty, or EU Battery Regulation passport and carbon-footprint regime for Na-ion BESS exports. GB/T 42288 and GB/T 44265 address technical safety and performance rather than UK or EU producer-responsibility registration.GB/T 44265-2024 — sodium-ion stationary storage technical specifications
GB/T 42288-2022 — electrochemical energy storage station safety
Chinese domestic recycling rules — not transferable to UK or EU producer registration		 For Great Britain, batteries placed on the market must comply with the Batteries and Accumulators (Placing on the Market) Regulations 2008 for restricted substances and labelling, and the Waste Batteries and Accumulators Regulations 2009 for producer registration, take-back, and reporting. A Na-ion BESS battery will normally be an industrial battery for UK battery EPR purposes. If the same product is placed in Northern Ireland, the EU, or is supported by an EU CE route, Regulation (EU) 2023/1542 may add chemistry-neutral obligations such as CE marking for batteries, carbon footprint, due diligence, labelling, recycled content, and digital battery passport requirements according to category and timing. UK and EU battery regimes should therefore be tracked separately.Batteries and Accumulators (Placing on the Market) Regulations 2008 (SI 2008/2164)
Waste Batteries and Accumulators Regulations 2009 (SI 2009/890)
Regulation (EU) 2023/1542 — relevant for EU market, Northern Ireland exposure, or EU CE-route planning; chemistry-neutral battery regime		 The UK gap is operational rather than test-method based: the UK importer or producer must register and report under UK battery EPR, apply required battery labelling, and hold substance-compliance evidence. The EU / NI gap is broader because Regulation 2023/1542 creates battery-specific conformity, data, carbon, due-diligence, and passport duties that have no Chinese domestic equivalent and may apply to the same commercial programme if Northern Ireland or EU sales are planned.Informational only. Treat UK battery EPR and EU Battery Regulation planning as separate from UKCA product-safety work. Na-ion chemistry does not remove UK producer-registration duties or EU chemistry-neutral battery obligations where those regimes apply.

Grid Connection — ENA EREC G99 for Na-ion BESS in Great Britain China's comparable technical references include GB/T 36558-2022 for electrochemical energy storage system grid connection, GB/T 34120-2023 for power conversion systems in electrochemical energy storage systems, and GB/T 42288 for electrochemical energy storage station safety. Chinese grid approval is handled by the relevant State Grid or Southern Grid entity and is not portable to a UK DNO.GB/T 36558-2022 — Technical requirements for grid connection of electrochemical energy storage system
GB/T 34120-2023 — Technical Requirements for Power Conversion System of Electrochemical Energy Storage System
GB/T 42288-2022 — Safety requirements for electrochemical energy storage station		 Na-ion chemistry does not change the Great Britain grid-connection route. A BESS connecting in parallel with the public distribution network normally follows ENA Engineering Recommendation G99 when above the microgeneration threshold, with G98 for smaller microgenerators. The Distribution Network Operator or Independent Distribution Network Operator reviews the application, protection settings, type-test evidence or site-specific assessment, commissioning forms, and witness-testing requirements. G99 is not a product-safety Act, but DNO approval is required before energisation of an in-scope grid-connected system.ENA Engineering Recommendation G99 — requirements for generation equipment connected in parallel with public distribution networks
ENA Engineering Recommendation G98 — microgenerator route for smaller systems
Distribution Network Operator / Independent Distribution Network Operator connection approval before energisation		 A Chinese grid-connection report cannot be used as G99 approval. Frequency and voltage ride-through settings, loss-of-mains protection, ROCOF settings, reactive-power controls, commissioning forms, and DNO witness-test expectations must be mapped to the specific UK network connection point. This workstream is separate from UKCA, battery EPR, and dangerous-goods transport.Informational only. Na-ion BESS needs the same G99 or G98 connection workflow as other battery storage. Start DNO engagement early because G99 approval, protection settings and commissioning evidence are site-specific and cannot be replaced by Chinese GB/T grid reports.

UKCA or CE Recognition in Great Britain — Product-Safety SIs for Na-ion BESS China has no direct equivalent to UKCA or Great Britain CE-recognition market access. For Na-ion stationary storage, manufacturers may use GB/T 44265-2024 for sodium-ion battery technical specifications, GB/T 42288-2022 for electrochemical energy storage station safety, GB/T 34120-2023 for electrochemical storage system power conversion systems, and GB/T 36558-2022 for grid-connection technical requirements. These Chinese standards and any voluntary CQC certification do not confer UK market access.GB/T 44265-2024 — Electrical energy storage power station: Technical specifications for sodium-ion battery
GB/T 42288-2022 — Safety requirements for electrochemical energy storage station
GB/T 34120-2023 — Technical Requirements for Power Conversion System of Electrochemical Energy Storage System
GB/T 36558-2022 — Technical requirements for grid connection of electrochemical energy storage system		 A sodium-ion battery energy storage system placed on the Great Britain market must satisfy every applicable UK product-safety instrument before a conformity mark is used. For typical electrical BESS this normally includes the Electrical Equipment (Safety) Regulations 2016 and the Electromagnetic Compatibility Regulations 2016; radio, machinery, pressure, RoHS or other rules may also apply depending on design. GOV.UK guidance confirms that Great Britain continues to recognise CE marking for many product regulations alongside UKCA under the Product Safety and Metrology (Amendment) Regulations 2024, but manufacturers must still compile technical documentation, complete the applicable conformity assessment, prepare a declaration of conformity, and identify the responsible economic operator. Designated or harmonised standards are voluntary routes that can support a presumption of conformity; they do not replace the legal obligations in the SIs.Electrical Equipment (Safety) Regulations 2016 (SI 2016/1101)
Electromagnetic Compatibility Regulations 2016 (SI 2016/1091)
Product Safety and Metrology (Amendment) Regulations 2024
GOV.UK guidance: Placing UKCA or CE marked products on the market in Great Britain
UK designated standards and EU harmonised standards — voluntary presumption-of-conformity routes where applicable		 The gap is structural: Chinese GB/T or CQC evidence can support engineering due diligence, but it does not replace the UK technical file, UK or recognised EU conformity assessment, declaration of conformity, marking, importer or authorised-representative duties, and post-market cooperation obligations. Na-ion chemistry also creates a standards-evidence gap because many battery standards were written around lithium technology, so deviations and applicability must be explained in the UK technical file.Informational only. A Chinese Na-ion BESS manufacturer should plan a UK technical file and conformity route under SI 2016/1101, SI 2016/1091 and any other applicable SIs, even if using continued CE recognition for Great Britain. Chinese GB/T reports alone are not a UKCA or CE-recognition file. Department for Business and Trade / GOV.UK2026-06-12 · unverified
BS EN IEC 62619 Route — Cell and Battery Safety Evidence for Na-ion Industrial Storage China's closest Na-ion-specific standard is GB/T 44265-2024 for sodium-ion battery technical specifications in electrical energy storage power stations. GB/T 42288-2022 provides chemistry-agnostic electrochemical energy storage station safety requirements, and GB/T 34120-2023 provides technical requirements for power conversion systems in electrochemical energy storage systems. These are useful domestic references but do not prove conformity with BS EN IEC 62619 or the UK Electrical Equipment (Safety) Regulations.GB/T 44265-2024 — Sodium-ion battery technical specifications for electrical energy storage power stations
GB/T 42288-2022 — Safety requirements for electrochemical energy storage station
GB/T 34120-2023 — Technical Requirements for Power Conversion System of Electrochemical Energy Storage System		 BS EN IEC 62619:2022 is commonly used in UK BESS safety files as evidence for secondary cells and batteries used in industrial applications. It is a standard, not a UK Act or SI, and its use is voluntary as a presumption-of-conformity route where the product falls within the standard and the relevant UK product regulation accepts the evidence. The standard title and scope are written for lithium cells and batteries, so Na-ion use should be justified with a written applicability statement, deviation analysis, supplementary chemistry-specific testing, and acceptance by the chosen UK approved body, EU notified body used for CE recognition, insurer, customer, or installer as applicable.BS EN IEC 62619:2022 — voluntary presumption-of-conformity route where accepted; explicit lithium scope requires Na-ion justification
Electrical Equipment (Safety) Regulations 2016 (SI 2016/1101) — mandatory legal safety objectives for covered electrical equipment
GOV.UK guidance on designated standards — standards are generally voluntary routes to presumption of conformity		 The key gap is not whether BS EN IEC 62619 is mandatory; it is not. The gap is evidential: a UK technical file needs a defensible bridge from Na-ion cell design and GB/T 44265 or GB/T 42288 data to the safety objectives of the UK regulations and any voluntary BS EN IEC 62619 clauses being claimed. A lithium-only 62619 report or a Chinese Na-ion GB/T report used without a deviation matrix is weak evidence.Informational only. Use BS EN IEC 62619 for Na-ion only as a voluntary evidence route with a clear scope and deviation justification. The binding UK obligation is compliance with the applicable product-safety SIs, not the standard itself. legislation.gov.uk — Electrical Equipment (Safety) Regulations 20162026-06-12 · unverified
Transport — UN 38.3, ADR / GB CDG and Dedicated Na-ion UN 3551 / UN 3552 Codes Chinese exporters also use UN 38.3 for international battery shipments. China domestic road dangerous-goods documents and carrier qualifications do not substitute for GB / ADR transport documents, packaging and training requirements. For Na-ion, exporters should classify cross-border documents directly under UN 3551 or UN 3552 where applicable and keep the Na-ion-specific UN 38.3 test summary available.UN 38.3 — used for export transport evidence
JT/T 617 — Chinese road dangerous-goods transport rules
CAAC dangerous-goods rules aligned with ICAO / IATA for air transport		 Na-ion cells and batteries shipped to or within Great Britain must be classified and transported under the dangerous-goods rules for the relevant mode. GOV.UK guidance explains that ADR governs road transport and that the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 apply ADR in Great Britain. The UN Model Regulations introduced dedicated sodium-ion entries for batteries with organic electrolyte: UN 3551 for sodium-ion batteries and UN 3552 for sodium-ion batteries contained in equipment or packed with equipment. UN 38.3 test evidence must be available for the specific Na-ion cell or battery type; a lithium-ion UN 38.3 report cannot be reused for Na-ion. Documentation, packaging, marking, labels, DGSA advice, and modal rules for ADR, IMDG, ICAO / IATA, or rail must be checked for each shipment.Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (SI 2009/1348)
ADR — applied in Great Britain through the GB CDG Regulations for road transport
UN Manual of Tests and Criteria, Part III, Section 38.3 — transport test evidence for Na-ion cells and batteries
UN 3551 — Sodium-ion batteries with organic electrolyte
UN 3552 — Sodium-ion batteries contained in equipment or packed with equipment, with organic electrolyte		 The test method is largely harmonised, but the classification and administration gap is material. Na-ion must not be shipped under legacy lithium-ion entries where the applicable regime has adopted UN 3551 / UN 3552. UK / ADR documents, English SDS and transport documents, correct Class 9 marking, appropriate packaging, and trained personnel must be arranged separately from Chinese domestic transport paperwork.Informational only. Classify Na-ion shipments as UN 3551 or UN 3552 where applicable, hold Na-ion-specific UN 38.3 evidence, and use ADR / GB CDG compliant documentation for Great Britain road movements. Confirm modal details with a DGSA before first shipment. Department for Transport / GOV.UK2026-06-12 · unverified
