Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tool steel composition per note (e)
Specific alloy element combinations (e.g., C+Cr thresholds) shift to tool steel wire heading.
If high-strength steel per note (a)
Meets yield point specs for high-strength flat-rolled equiv, but for wire uses strength criteria.
If imported as finished screws/bolts
Completed threaded fasteners from this wire classify under Chapter 73 articles of iron/steel.

Import Tips & Compliance
• Label with exact HTS statistical suffix based on diameter; importers often overlook 0.1mm differences affecting rates
• Ensure documentation shows cold-heading quality grade suitable for fasteners to support end-use claims if needed
• Avoid bundling with fittings; sets classify differently under composite goods rules
