Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of copper-nickel-zinc nickel silver composition
Alloys with ≥5% nickel content are nickel silvers, separated from standard brasses in the tariff.
If of copper-beryllium or other specialized copper alloys
Certain high-performance copper alloys like beryllium copper have dedicated subheadings.
If sold as copper alloy tube fittings or couplings
Fittings and connectors are classified in 7412 regardless of alloy type when not straight tubes.

Import Tips & Compliance
• Ensure documentation shows zinc > other elements and tin <3% to distinguish from bronze classification
• Measure and declare ID/OD precisely; tubes >114.3mm may require different statistical reporting
