Cartridge Brass Anode
Unwrought 70/30 copper-zinc alloy castings used as anodes in electroplating baths, falls under HTS 7403.29.0180 as refined other copper alloys.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If machined into bars
Any mechanical working beyond casting makes semi-manufactured goods.
If oxygen-free variant
Special purity copper alloys have dedicated oxygen-free headings.
If pre-insulated wire form
Electrical conductor preparation changes chapter 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
• Attach electroplating grade certification (e.g
• ASTM B111)
• Declare specific surface area for anode efficiency in entry documents
• Segregate from pure copper anodes to avoid classification disputes
