Compliance item Common China baseline Uzbekistan (O'zstandart / Uzenergo) Gap / action Source + verification date
Industrial Lithium Cell and Battery Safety — IEC 62619 / O'z DSt / GOST Adoption China commonly relies on GB 44240-2024 for compulsory safety of lithium-ion cells and batteries for electric energy storage and GB/T 36276-2023 for lithium-ion batteries for electric energy storage. These can support technical comparison but may not be accepted as the same standard as IEC 62619, IEC 62133, or the Uzbekistan-adopted O'z DSt / GOST version.GB 44240-2024
GB/T 36276-2023		 Uzbekistan BESS projects may request industrial lithium cell and battery safety evidence based on IEC 62619, IEC 62133, or O'z DSt / GOST adoptions, especially for stationary storage batteries used in BESS racks and containers. This evidence is usually reviewed together with the O'zstandart conformity file, project specifications, lender requirements, insurer requirements, and owner acceptance tests.IEC 62619 — Secondary cells and batteries containing alkaline or other non-acid electrolytes; safety requirements for industrial lithium batteries
IEC 62133 series — Safety requirements for portable sealed secondary cells and batteries where relevant to supplied battery scope
Applicable O'z DSt / GOST adoption of IEC battery safety standards where specified by the Uzbekistan project
O'zstandart conformity-file and project technical requirements		 Exporters should prepare a clause-by-clause comparison between GB 44240 / GB/T 36276 and IEC 62619, IEC 62133, or the required O'z DSt / GOST text, identify test differences for abuse, overcharge, thermal, short-circuit, BMS protection, and enclosure assumptions, and retest or supplement evidence where the Uzbekistan project owner, lender, or conformity body requires the IEC-based route.[INFORMATIONAL] GB 44240 and GB/T 36276 evidence should be mapped to IEC 62619, IEC 62133, or the specified O'z DSt / GOST adoption. Uzbekistan stakeholders may request IEC-based retesting or supplemental evidence. International Electrotechnical Commission (IEC)2026-06-14 · unverified
China GB / NB Baseline Versus Uzbekistan Evidence GB 44240-2024 is China's compulsory safety standard for lithium-ion cells and batteries for electric energy storage, while GB/T 36276-2023 is commonly used for lithium-ion batteries for electric energy storage. GB/T 34120-2023, GB/T 36558-2023, and NB/T 42090-2016 are common China-side PCS and grid-connected ESS references. Together they form the typical China-side technical baseline for a BESS export package.GB 44240-2024
GB/T 36276-2023
GB/T 34120-2023
GB/T 36558-2023
NB/T 42090-2016		 Uzbekistan stakeholders may accept Chinese GB 44240-2024, GB/T 36276-2023, GB/T 34120-2023, GB/T 36558-2023, and NB/T 42090-2016 reports as useful background evidence for BESS cells, PCS, and systems, but they generally need to be mapped to the Uzbekistan package: O'zstandart conformity certification, O'z DSt / GOST / IEC standards specified in the contract, grid-connection requirements, fire-safety review, transport evidence, and Uzbek or Russian technical documentation.O'zstandart mandatory conformity certification for regulated electrical products
IEC 62619 / IEC 62133 / IEC 62933 or applicable O'z DSt / GOST adoption
Uzbekistan grid, fire, transport, customs, and project requirements		 The practical gap is recognition and traceability. Exporters should prepare a document matrix showing which Chinese test report, drawing, BMS function, PCS setting, safety analysis, factory certificate, and commissioning record satisfies each Uzbekistan O'zstandart, O'z DSt/GOST/IEC, grid, fire, lender, and transport item, then identify missing retests, translations, local applicant documents, markings, and site records.[INFORMATIONAL] China GB/T and NB/T BESS evidence is a technical baseline, not an Uzbekistan clearance package. It should be mapped to O'zstandart certification, O'z DSt / GOST / IEC evidence, grid, fire, lender, and UN 38.3 deliverables.

Uzbekistan O'zstandart Conformity Versus EAC Context China BESS suppliers commonly hold GB 44240-2024 and GB/T 36276-2023 evidence for battery safety and performance, plus EMC or electrical-safety reports for PCS and cabinets. Some suppliers may also hold EAC certificates for Kazakhstan, Russia, or other EAEU markets. These reports can support technical comparison but do not by themselves create an Uzbekistan O'zstandart certificate of conformity or market-access right.GB 44240-2024
GB/T 36276-2023
China EMC and electrical-safety test reports for PCS / cabinets
EAC certificates for EAEU markets where separately held		 Uzbekistan is not an EAEU member; it has observer status, so EAEU EAC conformity under TR CU 004/2011 low-voltage safety and TR CU 020/2011 EMC should not be assumed to be the Uzbekistan legal route. In-scope BESS electrical equipment, PCS, control cabinets, auxiliary power equipment, and other low-voltage hardware should be assessed through Uzbekistan's domestic O'zstandart conformity route for regulated electrical products, using O'z DSt national standards and applicable GOST / IEC-derived evidence. EAC certificates may be useful background evidence for a project or regional procurement file, but they do not replace O'zstandart requirements where those apply.O'zstandart mandatory conformity certification for regulated electrical products
O'z DSt national standards and applicable GOST / IEC-derived electrical safety and EMC standards
EAEU observer status is contextual only; EAC/TR CU 004/2011 and TR CU 020/2011 are not assumed to be Uzbekistan legal market-access routes		 The main gap is legal route and document recognition. Exporters should classify the shipped BESS configuration under Uzbekistan rules, identify whether regulated electrical-product certification applies, engage an eligible O'zstandart-accredited conformity body or local applicant where required, prepare Uzbek or Russian technical files, map Chinese and any EAC evidence to O'z DSt / GOST / IEC requirements, and ensure markings and documents match the exact equipment placed on the Uzbekistan market.[INFORMATIONAL] Do not treat EAC as the Uzbekistan legal route. Chinese GB evidence and any EAC certificate should be mapped into the domestic O'zstandart / O'z DSt / GOST / IEC conformity file where Uzbekistan regulated-product certification applies.

BESS Fire Safety and Installation Approval China commonly relies on GB 44240-2024, GB/T 36276-2023, GB/T 36558-2023, and project-specific fire-safety review for stationary energy storage. These documents may support technical due diligence but do not replace Uzbekistan fire-authority, insurer, local permitting, lender, or project-owner expectations.GB 44240-2024
GB/T 36276-2023
GB/T 36558-2023		 Uzbekistan BESS installations may require fire-safety review under local building, emergency, industrial-safety, utility, and project-owner requirements. Review commonly focuses on container spacing, access, fire detection and alarm, suppression or mitigation design, ventilation, gas detection where relevant, emergency shutdown, thermal-runaway propagation controls, signage, and emergency response documentation. Large internationally-financed projects may apply IFC/EBRD lender and independent-engineer fire-safety requirements in addition to local approvals.Uzbekistan fire-safety and emergency-authority requirements for installations
Project-specific fire-protection design and local permitting requirements
Applicable O'z DSt / GOST / IEC fire and electrical installation standards specified by the project
IFC / EBRD lender fire-safety and environmental-social requirements where project financed		 A battery certificate, Chinese GB report, or EAC certificate does not close the Uzbekistan installation fire-safety gap. Exporters should prepare site layouts, fire-protection drawings, thermal-runaway mitigation evidence, fire and gas detection logic where relevant, ventilation calculations, emergency shutdown logic, remote monitoring records, fire-load assumptions, maintenance plans, and Uzbek or Russian emergency procedures for the project owner and authorities.[INFORMATIONAL] Chinese GB, EAC, or IEC battery evidence is not enough for Uzbekistan BESS fire approval. Installation fire-safety review and project-specific mitigation evidence should be handled before shipment or site commissioning.

220/380 V, 50 Hz Grid Frequency, Voltage, and PCS Parameter Settings China also uses 220/380 V, 50 Hz, so nominal voltage and frequency may match. However, Chinese PCS certificates and factory settings may use China-specific voltage ranges, protection curves, ride-through settings, reactive-power control, communication defaults, and grid-code assumptions that must be checked against Uzbekistan requirements.GB/T 34120-2023
GB/T 36558-2023
Chinese utility project settings		 Uzbekistan's national power system uses a nominal 220/380 V, 50 Hz supply, which is a small nominal voltage and frequency gap from China. BESS PCS, transformers, protection, HVAC, auxiliary supplies, metering, and controls must still be configured for Uzbekistan grid frequency, voltage level, earthing, protection, and network-owner operating windows. Project settings should be confirmed during grid studies and commissioning, not assumed from a China default configuration.Uzbekistan national power-system nominal: 220/380 V, 50 Hz
National Electric Grid of Uzbekistan / regional energy company technical conditions for project-specific protection and frequency settings
O'z DSt / GOST grid-protection standards where applicable
Project-specific PCS and protection commissioning requirements		 The gap is not nominal frequency alone but parameterization. Exporters should provide a Uzbekistan settings table covering frequency windows, voltage windows, ramp rates, active and reactive power controls, frequency response, protection trip points, transformer taps, auxiliary power compatibility, and commissioning records signed off by the network owner or project engineer.[INFORMATIONAL] Shared 220/380 V, 50 Hz nominal supply does not mean Chinese PCS settings are ready for Uzbekistan. Confirm local voltage, protection, ride-through, communication, and commissioning parameters before energisation. Government Portal of the Republic of Uzbekistan2026-06-14 · unverified
Uzenergo / Uzbekistan Grid-Connection Requirements for BESS and PCS China commonly uses GB/T 34120-2023 for electrochemical storage PCS technical requirements, GB/T 36558-2023 for system-level grid-connected ESS requirements, NB/T 42090-2016 for electrochemical energy storage PCS, and State Grid or China Southern Power Grid enterprise rules. These Chinese grid documents do not substitute for Uzbekistan network-owner or Uzenergo review.GB/T 34120-2023
GB/T 36558-2023
NB/T 42090-2016
State Grid / China Southern Power Grid project rules		 BESS projects connecting to Uzbekistan's national or regional power system must satisfy the applicable network owner, National Electric Grid of Uzbekistan / Uzenergo where transmission or system-operator review is involved, and Uzbekistan electricity-sector rules for the PCS, protection, metering, dispatch communication, power quality, operating modes, and commissioning. Requirements vary by voltage level, connection point, project size, market role, and whether the storage asset is paired with generation or load.National Electric Grid of Uzbekistan / Uzenergo technical conditions where applicable
Regional energy company connection requirements for distribution-level projects
Uzbekistan electricity grid and system-operation rules
Project-specific dispatch, protection, metering, telemetry, and commissioning requirements		 Chinese PCS type-test reports must be translated into Uzbekistan grid settings and local protection philosophy. Exporters should prepare relay settings, frequency and voltage ride-through data, anti-islanding data, reactive-power and power-factor capability, dispatch communication protocol evidence, metering design, single-line diagrams, model files where requested, and commissioning procedures for the Uzbekistan project owner and network review. Internationally-financed projects may additionally require lender independent-engineer review against IEC-based grid and storage specifications.[INFORMATIONAL] Chinese GB/T 34120, GB/T 36558, or NB/T 42090 evidence does not itself clear Uzbekistan grid connection. Local network-owner and, where applicable, Uzenergo or regional energy-company review must be addressed before energisation. Government Portal of the Republic of Uzbekistan2026-06-14 · unverified
BESS System Requirements — IEC 62933-5-2 / O'z DSt / GOST Project Acceptance China commonly uses GB/T 36558-2023 for general technical requirements for electrochemical energy storage systems connected to the power grid, GB/T 34120-2023 and NB/T 42090-2016 for PCS, GB 44240-2024 for battery safety, and GB/T 36276-2023 for battery technical requirements. These documents may not align one-to-one with IEC 62933 system documentation expectations.GB/T 36558-2023

GB/T 36276-2023		 Uzbekistan BESS projects may specify IEC 62933-series system requirements, including IEC 62933-5-2 safety requirements for grid-integrated electrical energy storage systems, or corresponding O'z DSt / GOST adoptions. These requirements cover system terminology, planning, safety, performance, grid interface, operation, and test documentation, and are typically applied at project design, procurement, commissioning, and owner acceptance rather than only at cell level.IEC 62933 series — Electrical energy storage systems
IEC 62933-5-2 — Safety requirements for grid-integrated electrical energy storage systems
Applicable O'z DSt / GOST adoption of IEC 62933 where specified by the Uzbekistan project
Project-specific technical specifications, lender specifications, and commissioning requirements		 The gap is system-level documentation rather than only component testing. Exporters should map Chinese system reports to IEC 62933 topics, provide system hazard analysis, interface definitions, control modes, availability and performance guarantees, commissioning test scripts, maintenance procedures, cyber or communication assumptions where relevant, and Uzbek or Russian evidence requested by the Uzbekistan buyer, O'zstandart body, lender, or independent engineer.[INFORMATIONAL] Chinese component certificates alone are not enough for Uzbekistan IEC 62933-style project acceptance. Prepare system-level design, safety, performance, commissioning, operation, and lender evidence where required. International Electrotechnical Commission (IEC)2026-06-14 · unverified
Lithium Battery Transport — UN 38.3 and Dangerous Goods Documentation China exporters commonly prepare UN 38.3 reports, MSDS/SDS, transport conditions appraisal reports, and dangerous-goods packaging documents for lithium battery shipments. These remain necessary but must match the exact cell, module, rack, container, state of charge, and transport route used for Uzbekistan.UN 38.3 test report and test summary
SDS / MSDS
Dangerous-goods packaging and transport documents		 Lithium cells and batteries shipped to Uzbekistan must have UN Manual of Tests and Criteria, Part III, subsection 38.3 test evidence where dangerous-goods transport rules require it. Exporters should prepare a UN 38.3 test summary, SDS, dangerous-goods classification, packaging evidence, and air, rail, road, or sea multimodal transport documents before shipment.UN Manual of Tests and Criteria, Part III, subsection 38.3
IMDG Code for sea transport where applicable
ICAO Technical Instructions / IATA DGR for air transport where applicable
Applicable rail and road dangerous-goods transport rules for Uzbekistan routing		 Transport evidence is configuration-specific. A UN 38.3 report for a cell may not cover a module, replacement pack, rack, containerized BESS, altered packaging, or changed state of charge. Uzbekistan importers, customs brokers, carriers, rail operators, and airlines may reject inconsistent test summaries, SDS classifications, package marks, or shipping names.[INFORMATIONAL] O'zstandart, IEC, EAC, or Chinese GB battery safety evidence does not replace UN 38.3 transport evidence. The exact Uzbekistan shipment configuration must be covered by the UN 38.3 test summary and dangerous-goods documents. United Nations Economic Commission for Europe (UNECE)2026-06-14 · unverified
