Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not round cross-section
Non-round high-carbon bars/rods use heading 7214 instead of wire-specific 7217.
If stainless or heat-resisting alloy steel
Alloy variants per notes (g,h) classified under 7229 other alloy wire.
If drawn into finer strand and twisted into rope
Stranded wire products become Chapter 73 articles.

Import Tips & Compliance
• Document oil-quenching process as qualifying heat treatment; simple annealing insufficient
• Ensure no phosphatizing or other 'further worked' per Chapter 72 note, or shifts to 7217.20+
• Use calibrated micrometers for diameter; CBP tolerances strict for statistical reporting
