## Conclusion first: The parallel period is not "valid forever," and label changes should be prioritized by SKU
The UK government has repeatedly extended the recognition period for the CE marking in the UK, but **parallel recognition is not a permanent arrangement**. For sellers exporting to the UK, 2026 should be the year to treat UKCA (UK Conformity Assessed, the local compliance marking replacing CE after Brexit) as a mandatory action rather than waiting for notice.
The practical judgment is simple: - SKUs already sold in the UK market whose packaging/nameplates bear only CE have the highest priority; - Long-tail SKUs accounting for less than 5% of UK site sales can be evaluated for "delisting rather than relabeling"; - New products should be designed with UKCA documentation from the start to avoid a second revision.
Among the UK site inquiries received by the Shuwang Testing and Certification Platform in 2026, most questions are not "whether to do it" but "which documents can be reused and which must be redone."
## Step 1: Determine the applicable regulations; do not focus on just one mark
UKCA is not a single regulation but a combination of UK domestic regulations. Common correspondences are as follows (reference ranges; the original text on the UK government official website shall prevail):
| Product category | Applicable UK regulation | Relationship with EU regulations | Common test reuse level | | --- | --- | --- | --- | | Electrical and electronic (safety) | Electrical Equipment (Safety) Regulations 2016 | Highly close to the technical content of LVD 2014/35/EU | High; reports can be reused; standard versions need to be checked | | Electromagnetic compatibility | EMC Regulations 2016 | Close to EMC 2014/30/EU | High | | Radio equipment | Radio Equipment Regulations 2017 | Close to RED 2014/53/EU | Medium-high; frequency bands and power limits need to be compared item by item | | Toys | Toys (Safety) Regulations 2011 | Close to Toy Safety Directive 2009/48/EC | Medium; the UK adoption status of EN71 series standard versions needs to be confirmed | | Machinery | Supply of Machinery (Safety) Regulations 2008 | Close to Machinery Directive 2006/42/EC | Medium; some harmonized standard versions differ | | Hazardous substances | RoHS Regulations 2012 | Close to RoHS 2011/65/EU | High |
Key point: **Close technical content does not mean documents can simply be given a new cover**. The technical file, the declaration of conformity (DoC, a compliance declaration signed by the manufacturer), the header, UK responsible person information, and cited standard versions required by UKCA all need to be rewritten according to UK requirements.
## Step 2: Boundaries between document reuse and rework
Reusable parts (reference ranges): - Test reports issued by partner laboratories, if the standard versions are consistent with the versions adopted in the UK, can usually be reused; - Circuit diagrams, BOM, instructions, and critical component lists; - Risk assessment framework.
Parts that must be redone or supplemented: - UKCA declaration of conformity (UK DoC), which must list the names of UK regulations and the UK responsible person; - Nameplates and packaging: UKCA marking proportions, clarity, and traceability information; - If the product has no UK local responsible party, a UK Responsible Person must be designated (the entity performing compliance obligations in the UK on behalf of the manufacturer).
Fee reference range: For the UKCA document preparation and marking change for a single electronic SKU, the publicly disclosed industry range is approximately RMB 1,500–12,000; projects involving supplementary testing usually fall within RMB 5,000–20,000. The reference lead time is 5–10 working days, extended to 15–25 working days if supplementary testing is required.
## Step 3: Document checklist for listing on Amazon UK
Platform review usually requires: 1. UKCA declaration of conformity (PDF, including signatory, date, and UK responsible person); 2. Test report (issued by a qualified partner laboratory); 3. Product label
and the six-sided packaging artwork; 4. UK responsible person information; 5. If it is a toy, a declaration and warnings compliant with UK toy safety regulations are also required. The most frequent reasons for delisting are not "no certificate," but rather **the standard version on the DoC being inconsistent with the report**, **the UKCA mark size on the nameplate being non-compliant**, and **missing UK responsible person information**. ## Step 4: Merging Strategy for CE and UKCA For the same product entering both the EU and UK markets, it is recommended to plan at the testing stage in one go: - Choose a standard version adopted by both sides for testing; - Address the report headers separately to the two DoCs for the EU and UK; - Use a "dual-marking" design for packaging to reduce secondary printing costs. The role of the Shuwang Testing and Certification Platform is to: determine applicable regulations, match partner laboratories and notified bodies (NB, EU-authorized certification bodies) with the corresponding authorized scope, organize the preparation and pre-review of technical documents, with the final certificate issued by the institution and the DoC signed by the manufacturer.

The testing described on this page is completed by partner laboratories with CNAS/CMA or equivalent qualifications, and certificates are issued by EU notified bodies (NB) or institutions authorized by the standards bureau of the destination country. The timelines and fees on this page are public industry reference ranges, and the actual ones are subject to engineer assessment and institution scheduling. ## One-sentence conclusion For the UK market in 2026, UKCA is not an option to "wait and see," but a systematic engineering task of prioritizing by SKU, reusing test reports first, and then rewriting the DoC and nameplate.
