More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cold-drawn alloy steel version
Steel boiler/heat exchanger tubes use 7304; cast iron lacks the alloy specs for that heading.
If stainless steel for corrosion resistance
Stainless variants for heating shift to 7307.22 due to material composition overriding cast iron.
If imported with boiler assemblies
Parts of boilers classify under 8403.90 if presented as such, per Section XVI assembly rules.
