Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloyed with zinc forming brass composition
Copper-zinc base alloys (brasses) are classified under 7407.22 per chapter notes when zinc predominates over other elements.
If made from copper-zinc alloys (brass wire)
Brass wire, regardless of thickness, shifts to 7408.21 following subheading note (a) definitions.
If further worked into nails, tacks, or pins
Secondary processing into fasteners moves it from base wire to Chapter 74 articles.

Import Tips & Compliance
• Provide chemical analysis reports confirming oxygen content <10 ppm to validate refined, non-alloy status
• Ensure commercial invoice specifies exact diameter and 'uninsulated wire' to prevent confusion with bars or rods
• For EU imports, check REACH compliance for copper impurities that could affect classification
