Timing Belt with Fiberglass Reinforcement
A non-endless timing belt made of vulcanized rubber reinforced with fiberglass cords and textile facing, used in automotive and machinery synchronization.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied endless
Timing belts shipped in closed loops are endless and classified separately under the endless textile-combined subheading.
If predominantly plastic rather than vulcanized rubber
Belts of plastics (e.g., polyurethane) with textile fall under Chapter 39, as Chapter 40 is limited to vulcanized rubber per legal definition.
If part of a complete pulley drive system
When imported as a set with pulleys for transmission, it may classify as machinery parts under Chapter 84 rather than individual belting.

Import Tips & Compliance
• Include engineering drawings showing textile cord embedding in rubber matrix to confirm combination per heading 4010 note on textile-covered rubber
• Label with precise material composition (e.g
• NR/SBR rubber with polyester textile) for CBP verification; avoid generic 'rubber belt' declarations
