Bottom line:
what can be combined is "test samples and engineering data"; what cannot be combined is "regulatory determination and certificate subject." When the same product is listed on Amazon US and Europe at the same time, sellers most often ask "can it be tested once and used on both sides." To put it accurately: some test items can be completed in one go on the same sample, and engineering data can be reused; but the basis for CE and FCC determination, the certificate/report subject, and the form of the declaration of responsibility are completely different and cannot replace each other. According to public industry reference ranges: the FCC certification cycle is 5–15 working days, with a cost of 1,000–12,000 yuan; the CE-EMC cycle is 5–10 working days, with a cost of 1,000–9,000 yuan; if the product is children's products, the CPC cycle is 7–15 working days, with a cost of 1,000–8,000 yuan. The savings from combined processing mainly come from samples and engineering time, not from the certificate fees themselves.
Which items can be combined and which must be separated
Electromagnetic interference (EMI) — US site requirements: FCC Part 15; European site requirements: CE-EMC (2014/30/EU); Can engineering data be shared: Some test data can be shared; the determination limits are different
Radio frequency (wireless products) — US site requirements: FCC ID; European site requirements: CE-RED (2014/53/EU); Can engineering data be shared: Test items overlap; the certification paths are different
Electrical safety — US site requirements: UL report (not legally mandatory); European site requirements: CE-LVD (2014/35/EU); Can engineering data be shared: The standards systems are different and are generally not shared
Children's products — US site requirements: CPC (CPSIA); European site requirements: CE-EN71 (2009/48/EC); Can engineering data be shared: Cannot be shared; the limits and items differ greatly
It should be emphasized that although both FCC and CE-EMC test electromagnetic interference, the limit curves, test setups, and determination criteria come from different standards systems. Engineering data can be referenced, but reports and declarations must be issued separately.
The correct order for combined processing 1. First make the regulatory determination: confirm whether the product is wireless equipment, whether it is children's products, and whether it falls within the LVD voltage range. An incorrect determination will make subsequent testing useless. 2. Then define the test plan: have a partner laboratory (with CNAS/CMA or equivalent qualification) issue a test plan covering both sets of standards, and complete overlapping items on the same sample as much as possible. 3. Issue certificates separately: FCC follows the SDoC or certification path; for CE, the manufacturer signs the declaration of conformity (DoC); for directives involving a notified body (NB, a third-party certification body designated by the EU), then coordinate with the NB. 4. Finally prepare the platform document package: archive the category review materials for Amazon US and Europe separately to avoid mixing them. Testing is completed by partner laboratories, CE certificates are issued by NBs (if applicable), and FCC reports and declarations are issued by the corresponding responsible parties.
Cost breakdown and three cost-saving boundaries The savings from combined processing mainly lie in: - Sample cost: one submission covers multiple sets of tests, reducing duplicate samples and logistics. - Engineering time: overlapping items are tested once, and the overall cycle can be compressed by 3–7 working days (reference range). - Document reuse: the product description, structure diagrams, and key component list in the technical file can be shared. Three places where savings cannot be made: - Regulatory determination cannot be skipped: an incorrect determination is the largest hidden cost. - Children's product testing cannot be skipped: the differences between CPC and EN71 items are large and cannot replace each other. - Platform documents cannot be mixed: the review criteria for the US site and the European site are different, and mixing them can easily lead to requests for supplementary documents.

On live projects the delay is rarely the testing itself; it is documents that do not line up before the sample ships.

Service boundary: Shuwang Certification Platform is an export certification solution provider. It does not perform testing and is not a certification body. Testing described on this page is carried out by partner laboratories accredited to CNAS/CMA or ISO/IEC 17025; certificates are issued by EU Notified Bodies or by the authorised bodies of the destination country. Lead times and cost ranges are public industry references and depend on engineer assessment and body scheduling.
, and the certificate is issued by an EU Notified Body (NB) or an institution authorized by the standards bureau of the destination country. The cycle and fees on this page are public industry reference ranges, and the actual ones are subject to engineer assessment and institution scheduling.
The takeaway:
The real savings from handling the US site and the European site together come from samples and engineering time (which can be compressed by 3–7 working days, reference range), not from certificate fees; the determination and issuing entities for CE, FCC, and CPC must be kept separate, and mixing them is a high-frequency cause of supplementary submissions and delisting.
