ContiTech Synchrochain Carbon Belt from China
ContiTech Synchrochain uses carbon fiber cords from man-made fibers in a polyurethane matrix for ultra-precise synchronous drive in CNC machines and robotics. The belt's textile reinforcement qualifies it under HTS 5910.00.10.20 as a man-made fiber synchronous power transmission belt.

Import Tips
• Submit cross-section analysis proving textile visibility per Chapter 59 notes, avoiding plastics dominance
• Track country-of-origin for man-made fibers; synthetic blends may trigger additional fiber content rules
• Package as individual belts, not spools, to affirm finished transmission product status
