Release time：
2025-11-26
Core certification: CCC certification (mandatory safety certification, with CCC mark and certificate number on the wiring harness, which can be verified for authenticity on the official website of the National Certification and Accreditation Administration).
Certification: Confirm that 'there is evidence to verify', reject 'three wireless bundles'
Legitimate standard wiring harnesses must pass national/industry mandatory certification, which is a "hard indicator" of quality:
1. Essential certification mark (domestic market)
Core certification: CCC certification (mandatory safety certification, with CCC mark and certificate number on the wiring harness, which can be verified for authenticity on the official website of the National Certification and Accreditation Administration).
Standard number: The corresponding national standard number should be printed, such as:
High voltage wiring harness: GB/T 25085 "High voltage cables for road vehicles" (applicable to new energy vehicles);
Low voltage wiring harness: GB/T 25087 "Low voltage cables for road vehicles".
Warning signs: High voltage harnesses must be printed with the warning message "High Voltage Danger" and labeled with voltage levels (such as "60V" and "300V+") and withstand voltage levels (such as "≥ 250V").
2. Reject the following products
No identification (no brand, no certification, no voltage/wire diameter labeling);
Blurred identification and easy wiping (poor quality printing);
Falsifying certification (can be verified by entering the certificate number on the CCC official website).
