FCC and CE Certification for Electronics from China

Many Chinese factories will tell you their products are “FCC and CE certified.” Some are correct. Some have real certificates for the version they showed you, not for the version they will ship you. Some have test reports — which are not the same as certification. And some have certificates that list the factory as the certificate holder rather than you, which means the certificate becomes worthless the moment you change suppliers.

This guide is about how to tell the difference, how to structure certification so you actually own it, and what to expect from labs and factories in China when you go through the process yourself.

1. The fundamental rule: certification belongs to the product and its seller

Before anything else, get this straight: FCC and CE certification applies to a specific product configuration sold under a specific entity’s name. It does not belong to a factory, and it does not transfer automatically when something changes.

FCC grants are issued by a Telecommunications Certification Body (TCB) and list a grantee — an entity with an FCC Registration Number (FRN). That grantee is legally responsible for the product’s compliance. If a Chinese factory lists themselves as the FCC grantee on a product you’re selling in the US, you don’t control that certification. The day you change suppliers or the factory goes bankrupt, you lose the right to sell under that FCC ID.

CE marking is a manufacturer’s self-declaration. The Declaration of Conformity (DoC) is signed by the manufacturer or their EU Authorized Representative. For a company outside the EU selling into the EU, an EU Authorized Representative is legally required — someone physically present in the EU who holds the technical file on your behalf. A Chinese factory cannot serve as your EU Authorized Representative.

This means: if a factory offers you a “CE certificate” signed under their own name for a product you’re going to import and sell, that document protects them, not you. EU market surveillance pulls units off shelves and requests the technical file from the EU importer. If your name isn’t on the DoC, you’re selling uncertified goods.

2. Three ways Chinese suppliers get certification wrong

Fake or irrelevant certificates

This happens more often than most buyers expect. The most common version: a factory sends a CE or FCC certificate for a product that looks similar to yours but is a different SKU, a different board revision, or a product from a different supplier entirely. They’re not necessarily forging documents — they’re showing you certification that genuinely exists but doesn’t apply to your product.

A less common but more serious version: fabricated certificates. FCC certificates have a verifiable format and a public database. CE certificates can’t be centrally verified — which makes them easy to fabricate. A professional-looking CE test report from a lab with a vaguely familiar name is not the same as a test report from an accredited lab.

Module certification ≠ product certification

This is where technically-aware buyers get caught. A wireless module — an ESP32-WROOM, an nRF52840 module, a Sierra Wireless modem — often has its own FCC grant and CE certification. The factory will tell you their product uses a certified module and is therefore certified.

This is not automatically true. Module certification covers the module itself, operating under specific conditions. When you integrate that module into a product with its own enclosure, power supply, and antenna configuration, the system-level behavior changes. FCC and CE require system-level testing unless you meet specific integration conditions — typically: using the module’s approved antenna without modification, keeping the module in the same configuration it was certified in, and following the module’s integration instructions precisely.

If the factory has modified the antenna layout, added a battery that introduces conducted noise, or changed the RF power output, the module’s certification does not extend to the product. You need system-level testing.

Component substitution after certification

A product passes FCC and CE testing with a specific BOM. Then, because a component goes on allocation or a cheaper alternative appears, the factory substitutes a component that changes the RF characteristics or EMC performance. The certificate remains valid on paper, but the product being shipped no longer matches the certified configuration.

This is why we treat certification verification as part of production quality control, not just a pre-shipment checkbox. See our guide on electronics quality control in China for how component-level verification works in practice.

3. How to verify FCC certificates

The FCC maintains a public database of all granted authorizations. There is no excuse for not checking it.

Step 1: Find the FCC ID on the product label or in the factory’s documentation. FCC IDs have a consistent format: a three-letter grantee code (the entity’s assigned prefix) followed by a product-specific code. Example: 2ABCDE-WIDGET1.

Step 2: Search fccid.io (aggregated database with better search) or the official FCC Equipment Authorization System at apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm.

Step 3: Confirm:

• The grantee name matches the entity you expect (your company, or a company you have an agreement with)
• The grant date is current — check if there are subsequent Class II Permissive Change or C2PC filings that supersede the original grant
• The equipment class matches the product category
• Test reports are available (most TCBs upload them; some are held confidential at the grantee’s request, but you can ask the factory to provide them)

If the FCC ID doesn’t appear in the database, or the grantee is a Chinese factory rather than your company, the certificate is not usable for your purpose.

4. How to verify CE compliance

CE is harder to verify because there is no central European database equivalent to the FCC’s. Market surveillance works by pulling products from shelves and requesting the technical file from the importer.

The documents you should request from any supplier claiming CE compliance:

Declaration of Conformity (DoC) — a signed statement listing the product name, model number, applicable directives and standards, and the name and signature of the authorized signatory. The signatory must be an entity with a legal presence in the EU, or the manufacturer themselves (only valid if they have an EU Authorized Representative arrangement).

Test reports from an accredited laboratory — the DoC is backed by test data. The lab must be accredited for the relevant test standards. For RED compliance: EN 300 328 for 2.4 GHz WiFi/BLE, EN 301 893 for 5 GHz WiFi, EN 62368-1 for safety. Accreditation is verifiable — EU test labs hold accreditation from bodies like DAkkS (Germany), UKAS (UK), or COFRAC (France). Ask which accreditation body certified the lab and verify it.

Technical file — the full documentation package: schematics, BOM, risk assessment, user manual (in each EU market’s language), and the test reports. EU importers are legally required to hold this file for 10 years post-sale and provide it to market surveillance authorities on request.

Red flags: a CE “certificate” with no associated test reports, test reports from a lab with no verifiable accreditation, a DoC signed by a Chinese entity with no EU Authorized Representative named, or a DoC citing outdated directives (the R&TTE Directive, for example, was replaced by RED in 2017).

5. Labs in China that can do the actual testing

Contrary to what some suppliers imply, FCC and CE testing cannot happen at the factory. It requires calibrated anechoic chambers, semi-anechoic chambers, and specific test equipment maintained under accreditation. The factories facilitate the process — they provide samples, access, and documentation. The actual testing happens at an accredited lab.

The labs with the credibility and equipment to issue usable FCC and CE test reports from China:

SGS — Shenzhen and Shanghai. Full FCC TCB capability, EU Notified Body status under multiple directives including RED. SGS Shenzhen can run FCC Part 15B/C, CE RED, CE EMC, and CE LVD from a single facility.

TÜV Rheinland — Guangzhou and Shanghai. German notified body (one of Europe’s most recognized) with FCC recognition. The Guangzhou lab covers both FCC and CE RED scope.

Intertek — Shenzhen. FCC accreditation under A2LA, EU Notified Body, UK Approved Body (relevant for UKCA post-Brexit).

Bureau Veritas — Shenzhen. EU Notified Body, FCC-recognized, full EMC and safety scope.

All four will issue FCC TCB grants and EU test reports that are accepted by market surveillance authorities. The key question when engaging any lab: ask explicitly which accreditation body issued their FCC recognition and which Notified Body number covers the directives you need. Legitimate labs answer this immediately.

A note on cost: Shenzhen lab testing costs are lower than equivalent testing in Europe or the US — typically 30–50% less — for the same accreditation level. The test reports carry identical weight with regulators.

6. The module shortcut and where it stops

If your product uses a pre-certified wireless module — an Espressif ESP32 module, a Nordic nRF52840 module, a u-blox cellular module — you may be able to avoid full radio type testing and run only system-level EMC and safety tests. The module’s existing FCC grant and CE certification cover the radio itself.

This is legitimate and commonly used. The conditions:

• You use the module’s approved antenna, at the approved output power, without hardware modification
• The module’s integration guide is followed — antenna clearances, keep-out zones, and RF layout guidelines
• Your product does not add additional radio functionality beyond what the module covers
• The module manufacturer has granted you written permission to reference their grant (most do; check the FCC grant for the permissive change status)

When the shortcut applies, you avoid 4–8 weeks of radio testing and save $2,000–6,000. You still need Part 15B system-level EMC testing — which covers unintentional emissions from your enclosure, power supply, and digital circuitry, not the radio itself.

When the shortcut does not apply: you’ve changed the antenna, added a custom RF front-end, moved the module to a position that violates its integration guidelines, or you need to list your company as the FCC grantee (in which case you file a Class II Permissive Change against the module’s grant, or get a new grant entirely).

7. Realistic costs and timelines from China

For a wireless consumer electronics product (BLE only, no mains voltage) using a pre-certified module, targeting US + EU:

For the same product without a pre-certified module, add full radio type testing:

These figures assume a single product variant targeting a single frequency band. Multiple SKUs or multiple frequency bands scale cost approximately linearly. See our multi-market certification guide for how to run FCC + CE + UKCA + PSE in parallel rather than in sequence.

8. What your purchase order needs to say

Certification language in purchase orders is frequently vague — “product must meet FCC and CE requirements” — which means nothing enforceable when the product ships without valid certification.

Specific terms that close this gap:

FCC ID grantee: The FCC grant must list [your company name / your authorized entity] as the grantee. The factory cannot be the grantee. Specify this before sampling.

CE DoC signatory: The Declaration of Conformity must be signed by [your entity] or a named EU Authorized Representative designated by you. Provide the required information when placing the order.

Test reports required: Specify that lab test reports from an A2LA or NVLAP-accredited lab (for FCC) and a UKAS/DAkkS/equivalent-accredited lab (for CE) must accompany the shipment. Factory-internal test reports do not satisfy this requirement.

Component freeze post-certification: Include a BOM lock clause stating that any change to components affecting RF performance, EMC characteristics, or safety requires written approval and may require re-testing. Unauthorized substitution after certification is a material breach.

Technical file access: For CE, require that the complete technical file — schematics, BOM, test reports, and DoC — be delivered to you digitally before or at first shipment, and that you retain it for the required 10-year period.

These are not unusual demands. Factories with legitimate certification experience include all of this in their standard process. Factories that resist listing your entity as the FCC grantee or that resist providing the technical file are, in most cases, either not able to do so (their certification doesn’t support it) or unwilling (they’re treating the certification as their IP). Both are problems to resolve before placing the order, not after.

For products requiring certification across multiple markets simultaneously — US, EU, UK, and Japan in the same launch window — the parallel testing structure in our multi-market certification guide applies. The principles in this guide (own the grants, verify the labs, lock the BOM) are prerequisites regardless of how many markets you’re certifying for.
