EMC — Electromagnetic Compatibility Regulations 2016 for GaN Fast Chargers China-market EMC evidence for chargers may include GB/T 9254.1, GB/T 9254.2, GB 17625.1 and product-classification-dependent CCC evidence. Those reports may be technically useful, but they do not replace a Great Britain EMC technical file or a UK Declaration of Conformity where UKCA is used.GB/T 9254.1
GB/T 9254.2
GB 17625.1
CCC requirements where applicable		 GaN fast chargers and USB-C power adapters placed on the Great Britain market must meet the essential requirements of the Electromagnetic Compatibility Regulations 2016: equipment must be designed and manufactured so electromagnetic disturbance does not exceed a level allowing radio, telecommunications and other equipment to operate as intended, and must have adequate immunity for intended operation. UK designated EMC standards are voluntary routes to presumption of conformity; the mandatory obligation is the Regulations, technical documentation, conformity assessment and applicable product marking.The Electromagnetic Compatibility Regulations 2016 (SI 2016/1091)
BS EN 55032 / BS EN 55035 / BS EN IEC 61000 series (designated-standard routes where applicable; voluntary presumption of conformity)		 The GaN switching topology can create conducted and radiated emissions that need GB-market evidence. Chinese domestic EMC reports may not cite UK designated standards or the UK Regulations, and edition differences can matter. Exporters should map CN test evidence into a UK technical file or run UK/EU-aligned EMC testing where needed.[INFORMATIONAL] A GaN charger sold in Great Britain needs EMC conformity under the UK Regulations. CN EMC reports can support engineering analysis but are not a substitute for UK-regime conformity documentation. The National Archives / legislation.gov.uk2026-06-12 · unverified
Great Britain Market Access — UKCA and Accepted CE Marking China-market access is generally based on CCC, GB 4943.1 safety evidence, China EMC/material rules and China labelling. CCC is a third-party certification model for in-scope products, while Great Britain generally uses manufacturer conformity assessment and product marking with technical documentation.CCC
GB 4943.1-2022
China EMC and RoHS-related rules		 For many product sectors in Great Britain, UKCA marking is the UK conformity mark and CE marking continues to be accepted under UK government product-marking policy where the relevant rules allow it. A GaN charger entering Great Britain should map all applicable UK legislation, usually including the Electrical Equipment (Safety) Regulations 2016, Electromagnetic Compatibility Regulations 2016, UK RoHS and plug-safety rules. Northern Ireland follows different marking rules and may require CE/UKNI treatment depending on the conformity route.UKCA marking guidance for Great Britain

The Plugs and Sockets, etc. (Safety) Regulations 1994		 The market-access file must be rebuilt for Great Britain: applicable UK laws, declaration wording, importer or responsible economic-operator details, marking strategy, plug configuration and technical evidence all need UK review. CCC and China labels do not transfer automatically.[INFORMATIONAL] Great Britain market access for a China-made GaN charger should be treated as a separate UK conformity project covering UKCA or accepted CE, electrical safety, EMC, UK RoHS and BS 1363 plug obligations.

Plugs and Sockets — BS 1363 Plug Requirement for UK Domestic Appliances China-market chargers commonly use Chinese plug forms and China plug/socket standards. A CN plug configuration or travel adaptor approach is not equivalent to a UK BS 1363 plug for domestic supply in the UK.China domestic plug/socket standards
CCC requirements where applicable		 The Plugs and Sockets, etc. (Safety) Regulations 1994 require plugs, sockets, adaptors and certain appliances supplied in the UK to meet UK plug-and-socket safety requirements. For a mains-powered GaN charger intended to plug directly into a UK domestic socket, the UK plug interface normally needs a compliant BS 1363 plug construction with appropriate fuse arrangements where applicable. This plug-safety duty is separate from UKCA/CE electrical-safety and EMC conformity.The Plugs and Sockets, etc. (Safety) Regulations 1994 (SI 1994/1768)
BS 1363 plug system requirements referenced by the UK plug-safety regime		 A charger body designed around CN, EU or US pins normally needs a UK-specific plug design, compliant conversion plug arrangement, or UK cordset strategy. The UK plug requirement is a market-entry blocker even where the electronics already satisfy GB 4943.1, UK electrical safety and EMC evidence.[INFORMATIONAL] A CN-plug GaN charger cannot be treated as UK-ready merely by adding product-safety test reports. The UK plug interface must be addressed under the Plugs and Sockets, etc. (Safety) Regulations 1994 and BS 1363 practice. The National Archives / legislation.gov.uk2026-06-12 · unverified
UK RoHS — Restricted Substances in Electrical and Electronic Equipment China RoHS and related material-declaration rules use a different compliance and marking framework from UK RoHS. GB/T 26572 material limits may be relevant technical evidence, but China RoHS labels, EFUP markings or supplier declarations do not automatically satisfy UK RoHS documentation and conformity duties.GB/T 26572
China RoHS management measures		 GaN fast chargers placed on the Great Britain market are electrical and electronic equipment and must comply with the UK RoHS regime under the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012, as amended. Manufacturers must control restricted substances in homogeneous materials, keep technical documentation, and support the applicable UKCA or accepted CE conformity route.The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012 (SI 2012/3032) The substance-control concept is similar, but the legal framework, declaration evidence, exemptions, marking linkage and enforcement are different. A China materials file should be reviewed against UK RoHS restricted substances and exemptions before UK market placement.[INFORMATIONAL] UK RoHS must be addressed separately from China RoHS. Supplier declarations and GB/T 26572 evidence should be checked against the UK restricted-substance and exemption framework. The National Archives / legislation.gov.uk2026-06-12 · unverified
Electrical Safety — Electrical Equipment (Safety) Regulations 2016 and BS EN IEC 62368-1 Voluntary Route In China, power adapters and chargers are commonly controlled through China Compulsory Certification (CCC) and the applicable safety standard GB 4943.1-2022 for audio/video, information and communication technology equipment. CCC uses designated certification bodies, type testing and factory inspection before the CCC mark may be used. GB 4943.1 evidence and CCC certificates are China-market evidence and do not by themselves satisfy Great Britain legal duties.GB 4943.1-2022
China Compulsory Certification (CCC)		 Finished GaN fast chargers and USB-C power adapters placed on the Great Britain market must comply with the legally binding Electrical Equipment (Safety) Regulations 2016 where they operate within the voltage scope. The manufacturer must carry out conformity assessment, prepare technical documentation, draw up a UK Declaration of Conformity where UKCA is used, and affix the applicable product marking before placing the product on the market. Designated standards such as BS EN IEC 62368-1 are voluntary: applying a designated standard can give presumption of conformity with corresponding safety objectives, but the legal obligation is compliance with the Regulations themselves and alternative technical solutions may be used if the file demonstrates conformity.The Electrical Equipment (Safety) Regulations 2016 (SI 2016/1101)
BS EN IEC 62368-1 (designated standard route; voluntary presumption of conformity)		 GB 4943.1-2022 and BS EN IEC 62368-1 share an IEC 62368-1 technical lineage, but the conformity systems are separate. A China CCC certificate or GB test report is not a UKCA/accepted CE technical file. Exporters need Great Britain conformity evidence, a UK Declaration of Conformity when using UKCA, and product labelling aligned with the UK regime.[INFORMATIONAL] A China-certified GaN charger still needs Great Britain electrical-safety conformity evidence before GB market placement. BS EN IEC 62368-1 can be used voluntarily to support presumption of conformity, but the mandatory duty is compliance with the Electrical Equipment (Safety) Regulations 2016.
