According to the basic principles of the "Description and Definition Table of Compulsory Product Certification Catalogue (Revised in 2020)" released by the Certification and Accreditation Administration in April 2020, the catalog of explosion-proof electrical CCC certification products is divided into the following 17 categories.
1. Explosion proof motor
2. Explosion proof electric pump
3. Explosion proof distribution device
4. Explosion proof switches, control and protection products
5. Explosion proof walking device products
6. Explosion proof transformer
7. Explosion proof electric actuator and solenoid valve
8. Explosion proof monitoring products
9. Explosion proof communication and signaling devices
10. Explosion proof air conditioning and ventilation equipment
11. Explosion proof electric heating products
12. Safety barrier
13. Explosion proof instrument box
14. Explosion proof accessories and Ex components
15. Plug in equipment
16. Explosion proof sensor
17. Explosion proof instruments and meters

Recently, the scope of the explosion-proof 3c product catalog has undergone minor adjustments, mainly including:
1. Clarify that the following products fall within the scope of CCC certification catalog:
(1) Tablet computer (2309);
(2) Explosion proof signal light/indicator light/warning light (only used as an Ex component for signal indication function, 2304);
(3) End box (as an accessory of electric heat tracing cable, 2303);
(4) Enhanced safety shell (2313);
(5) Human machine interface (2309);
(6) Slot/base module (slot/base module with electrical connection function, 2308);
(7) Inverter (2303);
(8) Explosion proof servo motor (2301);
(9) Sealing components, plugs, and joints (2313):
(10) Liquid level sensor (2315);
(11) Explosion proof buttons and button switches with indication function (2304);
(12) Electrohydraulic actuator/mechanism/device (2307);
(13) Positive pressure blowing control device (2304) for positive pressure products;
(14) Monitoring substation and transmission master station (2309);
2. Clarify that the following products are not within the scope of CCC certification catalog:
(1) Temperature instrument;
(2) Pressure sensor;
(3) QR code scanner, explosion-proof intelligent scanning terminal, etc;
(4) Gas sensors;
(5) Transmitters;
(6) Explosion proof breathing valve/drainage valve;
(7) Portable audio and video recorders for law enforcement purposes;
(8) Observation window;
(9) Combustible gas detector;
(10) Level gauge, liquid level gauge, flow meter.
3. Handheld terminals, specific products can be judged according to the functions specified in the catalog definition table to determine whether they belong to the scope of the CCC catalog.
