Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically admiralty metal composition
Admiralty brass has dedicated statistical category within copper-zinc tubes.
If imported pre-coiled for heat exchanger assembly
Coiled tubes for heat exchangers may classify as parts of machinery.
If very thin-walled capillary tubing
Capillary tubes <6mm have separate 'other tube' classification.

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
• Declare arsenic content; trace elements don't change base alloy classification
• Pressure test certificates often required for condenser tube imports
