CCC Certification for Explosion Protection Products in China

26. March 2020

With the announcement of the Chinese market regulation authority SAMR (State Administration for Market Regulation), a CCC certification is mandatory for many explosion protection products starting October 1, 2020. This means that a valid CCC-Ex certificate must be received for these products by October 1, 2020 at the latest, otherwise these products may no longer be imported to China. Up until now the explosion proof (“Ex”) products were excluded from the CCC obligation.

Explosion-proof product

With the announcement, the authority also published the new implementation rules CNCA-C23-01: 2019 in which it regulates which products have to be CCC certified in the future:


  • Explosion-proof motor
  • Explosion-proof electric pump
  • Explosion protection distribution systems
  • Explosion-proof switches, control and protection products
  • Explosion-proof starter products
  • Explosion-proof transformer products
  • Explosion-proof electrical drives and solenoid valves
  • Explosion-proof connector
  • Explosion-proof surveillance products
  • Explosion-proof air conditioning and ventilation systems
  • Anti-explosion communication, signaling device
  • Explosion-proof electrical heating products
  • Explosion-proof accessories, Ex components
  • Explosion-proof instrumentation products
  • Explosion-proof sensors
  • Safety barrier products
  • Explosion-proof instrument housing

Electronic products must be tested according to their Ex type. The GB standards regulate the necessary tests. Explosion-proof products can be tested for one or more Ex types.

According to the implementation rule CNCA-C23-01: 2019 the following tests result:

No. Explosion-proofing type Criteria
General Standards Detailed Standards
1 Explosion suppression “d” GB3836.1 GB3836.2
2 Increased safety “e” GB3836.3
3 Intrinsically safe “i” GB3836.4
4 Positive pressure enclosure “p” GB/T3836.5
5 Immersion “o” GB/T3836.6
6 Sand filling “q” GB/T3836.7
7 “n” type GB3836.8
8 Encapsulation “m” GB3836.9
9 Intrinsically safe “iD” GB12476.1


10 Enclosure protection “tD” GB12476.5
11 Encapsulation protection “mD” GB12476.6
12 Positive pressure protection “pD” GB12476.7

If your company already has NEPSI (SITIIAS) certificates or IECEx test reports / certificates, product tests may be avoided or reduced. After a thorough examination of your documents (certificates, test reports, etc.), the Chinese authorities will decide whether further tests are necessary for the initial approval of your products.

Manufacturers of affected products from the explosion protection area are encouraged to start the certification process as soon as possible in order to have the CCC-Ex certificates available in time for the October 1, 2020 deadline.
