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 not longitudinally welded
Other welding types (e.g., electric resistance) use 7305.32, splitting the 'other welded' category.
If as parts of mining machinery
If imported specifically as slurry pump discharge pipes, Chapter 84 for machinery parts applies.
If flanged or with mechanical joints
Added connectors make it 'tube or pipe fittings of iron/steel' in 7307.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Specify abrasion-resistant alloy grade (e.g
• ASTM A588) with chemical analysis to justify HTS
• Ensure invoice notes 'not for boiler use' to avoid misrouting to high-pressure subheadings
