Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily cast iron construction
Cast iron dominates classification over plastic lining in 8481.90.1000.
If imported as loose PFA tubing/fittings
Plastic tubes/pipes/hoses without metal valve body go to Chapter 39.
If classified as saw band guide
Metal saw parts for wafer slicing may fall under Chapter 82 tools.
