About heading 7403

Refined copper and copper alloys, unwrought (other than master alloys of heading 7405)

Heading 7403 covers refined copper and copper alloys in unwrought form, other than master alloys. It splits first between refined copper and copper alloys. Refined copper lines cover cathodes, wire bars, billets and other forms; alloy lines cover brass, bronze, cupro-nickel or nickel silver, and other alloys.
