Scope & Limitations
Certifications apply to specific product families, not all products uniformly. Each product page lists the applicable certifications for that specific product.
- UL 1441 applies to fiberglass-based sleeving (silicone and acrylic coated) and PVC tubing. It does not cover PTFE tubing or heat shrink tubing.
- Full-color UL recognition: WCW Flex is the first manufacturer in China to achieve UL certification across the full color range under File E233804 / E233803 — all standard colors (black, white, red, yellow, blue, green and custom shades) are UL recognized, not just selected colors.
- IATF 16949 covers the quality management system for automotive applications. Individual product certificates should be verified for specific vehicle programs.
- RoHS and REACH compliance applies to all products. Test reports are available upon request.
