Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tin content 3% or higher
High tin shifts to copper-tin base alloy (bronze) per subheading note (b), changing from brass classification.
If pure copper or low-alloy
Non-zinc alloys or pure copper plates/sheets fall under refined copper heading, not brass.
If width exceeds 500 mm
Wider brass strip (>500 mm) classified separately even if same thickness and alloy.
