Key Certifications to Require from Your Supplier-USB CABLE
For export-oriented buyers, certification is non-negotiable. When evaluating a USB-C cable manufacturer, check for:
✅ USB-IF Certification
The USB Implementers Forum (USB-IF) certification validates that the cable meets official USB specification for signal integrity. Cables without this cert risk causing device damage or data loss at scale.
✅ CE / FCC / RoHS
CE: Required for EU market entry
FCC: Required for US market
RoHS: Required if selling in the EU — restricts hazardous substances in electronics
✅ E-Mark Chip for 5A / 100W Cables
USB-C cables supporting Power Delivery above 3A must contain an E-Mark chip. This is a hardware requirement from the USB-PD specification. Suppliers who omit this chip to cut costs are creating a fire hazard and a recall liability for your brand.
Buyer Tip: Always confirm whether the supplier's USB-C cable is a true USB 3.2/4 spec or uses a USB-C connector on a USB 2.0 wire — a common deceptive practice in low-cost sourcing.
At Fenfei, we clearly label each SKU with its data protocol and power delivery rating, and provide spec sheets for every product in our USB 3.0, 3.1, and 3.2 cable lines.
