Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-tin base alloy (bronze)
Bronze wire (tin predominant or specific ratios) uses other copper alloy subheadings.
If alloyed primarily with iron
Iron-based nickel alloys like constantan variants may fall under stainless steel wire in Chapter 72.
If drawn and suitable only for electrical conduction
Certain monofilament copper wires shift to Chapter 85 if specialized for electric signal use.

Import Tips & Compliance
• Certify exact alloy (e.g
• CuNi44) meets copper-nickel base definition; resistivity specs aid verification
• Package to prevent surface oxidation mistaken for coating; include uncoated declaration
