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 the tube is for oil or gas drilling
Tubes for oil or gas drilling are classified separately in the Customs Tariff.
If the tube is made of stainless steel
Stainless steel tubes have a distinct tariff classification from non-alloy steel tubes.
If the tube is welded rather than seamless
Welded tubes are classified under a different heading than seamless tubes.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the tube is non-alloy steel and seamless, as alloy steel or welded tubes are classified elsewhere
• Provide a mill test certificate to confirm the steel grade and manufacturing process
• Verify the internal diameter and wall thickness, as these affect the classification
