Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing 0.25% or more carbon
Carbon threshold splits 7217.30; >=0.25% C in plated round <1mm is .3030.
If further worked into springs
Wire formed into finished springs or shapes moves to 7314 for stranded/knotted wire.
If assembled into musical instrument parts
Complete string sets for instruments classify under Chapter 92.

Import Tips & Compliance
• Document alloy coating composition; 'other base metals' excludes precious metals per HTS structure
• Test for carbon content; piano wire variants over 0.25% C shift to adjacent subheadings
• Label as industrial wire, not consumer good, to avoid retail set packaging issues
