Recent news headlines have suggested that the U.S. Federal Communications Commission (FCC) has “banned all testing laboratories in China and Hong Kong.” Understandably, this has created concerns around PCB testing, material approvals, UL listings, and the continued use of established test laboratories in Asia.
The good news is that for most PCB, PCB material, and PCBA testing, nothing has changed. Let’s separate fact from fear.
What the FCC Decision Is Actually About
On 30 April 2026, the FCC voted on new rules affecting its equipment authorisation programme — the regulatory pathway that allows certain electronic devices to be placed in the U.S. market.
This programme applies specifically to end products that emit radio frequency (RF) energy, such as Wi‑Fi or Bluetooth devices, wireless products, and devices classified as intentional or unintentional radiators.
The FCC action focuses on where the final regulatory test reports for these devices are generated, particularly for products entering the U.S. market. It does not target general electronics testing, safety testing, materials testing, or PCB qualification work. This discussion becomes much clearer when we separate final product regulatory approval from component and process testing.
PCB, Materials and PCBA Tests Not Affected
The following tests remain fully allowed when conducted by test laboratories located in China or Hong Kong, including labs owned by U.S. or European organisations:
PCB and PCB Material Testing
- UL laminate and prepreg material recognition
- Flammability testing (e.g., UL94)
- PCB construction safety evaluations
- Comparative tracking index (CTI) testing
- Thermal, mechanical, and reliability testing
- Material qualification and re‑qualification testing
PCB Manufacturing and Process Testing
- Microsection analysis
- Plating thickness and metallurgical evaluation
- Solder mask and surface finish testing
- Cleanliness and ionic contamination testing
- CAF testing
- Thermal cycling, IST and reliability assessments
PCBA (Assembly‑Level) Tests, Non‑Regulatory
- Functional testing
- Environmental stress testing
- Thermal cycling and ageing
- Mechanical integrity testing
- Pre‑compliance EMC screening
None of these tests fall under the FCC equipment authorisation programme. As a result, UL, TÜV, Intertek, SGS, and other international labs operating in China can continue to perform these services exactly as before. The FCC rules become relevant only when testing is used as part of final FCC authorisation for an end device.
Tests That May Require a US (or Trusted Location) Lab
If a test report is intended for formal FCC submission, such as final EMC test reports, RF exposure measurements, transmitter compliance testing, and certification files for wireless devices, those specific test reports may need to be generated by an FCC‑recognised laboratory located in the U.S. or another “reciprocal/trusted” country, depending on how the final rules are implemented. This applies regardless of who owns the lab. The determining factor is physical location, not company nationality.
What This Means for the PCB Industry
For PCB designers, fabricators, material suppliers, and EMS providers, the impact is limited and indirect:
- PCB and material qualification flows are unchanged
- Existing UL files, material recognitions, and safety approvals remain valid
- Normal quality, reliability, and process testing in China continues
- Only final FCC regulatory testing of wireless end products needs closer attention
In practice, many companies will simply shift final compliance testing to eligible labs while continuing development, pre‑compliance, and component testing close to manufacturing sites.
The Takeaway
There is no general ban on PCB or material testing in China. The FCC action is targeted, regulation‑specific, and focused on end‑product FCC authorisation. PCB manufacturing, materials development, qualification, and reliability testing, including UL‑related activities, remain fully permissible at Chinese test laboratories.
For an industry already managing supply‑chain complexity, this clarification that there is no need to redesign testing strategies or panic about PCB approvals is important.
