Tin-Plated Phosphor Bronze Wire
Tin-plated admiralty brass wire is made from a copper-zinc-tin alloy (Cu-Zn-Sn <3%) and coated with tin, used for condenser tubes and heat exchangers. The base alloy meets the brass definition under subheading note 1(a) because tin content is less than 3%, and the tin coating makes it a metal-coated copper alloy wire. It is classified under tariff item 7408.29.00 as 'other' copper alloy wire.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the wire is formed into tubes or pipes
Copper alloy tubes and pipes are classified under heading 74.11, not as wire.

Import Tips & Compliance
• Confirm the tin content in the base alloy is below 3% to qualify as brass, not bronze, per subheading note 1(a)
• The tin plating is a coating and does not change the base alloy classification
• Keep alloy composition certificates to support the brass classification if requested by CBSA
