Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed for air pumps vs motors
Endless transmission belts/diaphragms of rubber shift to Chapter 40 function-based.
If integral to control valves
Pollution control valve parts classify under 8481 even in pneumatic systems.
If predominantly plastic-reinforced
Rubber content <50% routes to plastic articles in Chapter 39.
