Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If having circular cross section with 6mm+ wall thickness
Thicker-walled tubes for high-pressure apps fall into specific subheadings based on dimensions.
If made from copper-nickel alloys
Copper-nickel base alloys (per subheading note d) are classified under 7411.29, not refined copper.
If flexible tubes with plastic lining
Copper tubes with plastic inner lining are often classified as flexible plastic tubes by predominant material.
