CCC Certification
China Compulsory Certification (3C mark) required for electrical equipment sold in the Chinese domestic market.
The CCC mark is mandatory for electrical equipment sold domestically in China. Covers specific voltage/capacity ranges per CNCA.
Products requiring CCC: distribution transformers, HV switchgear, LV switchgear, ring main units, cable branch boxes. Process involves type testing to GB standards, factory inspection, and surveillance.
CCC differs from CE (European) or UL/CSA (North American). Export equipment needs destination certifications.
QDTB holds CCC for all domestic products and maintains international standards compliance for exports. Our CE guide and UL/CSA guide cover international requirements.
