Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as complete heat exchanger parts
Assembled or specialized condenser tubes classify under Chapter 84 machinery parts.
If suitable for oil/gas drilling
Drill pipe characteristics move to 7304.31 even if thin-walled.
If welded construction
Most condenser tubes are welded, classifying under 7306.40 or 7306.90.

Import Tips & Compliance
• Include U-bend specifications if applicable, but declare as straight tubes unless fully formed
• Provide corrosion resistance test data to justify nonalloy steel without alloy premiums
• Avoid classifying with fins, as finned tubes may go to 8419.50 as heat exchanger parts
