Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy tool steel per Chapter Note (e)
Music wire with specific alloying meeting tool steel definition in U.S. Note (e) classifies under 7229.
If not round cross-section
Non-round wire (square, shaped) classified separately from round wire in 7217.10.50.
If further worked with surface treatment like coating
Chapter 72 note defines 'further worked' including metal coatings, moving to worked wire heading 7214.

Import Tips & Compliance
• Include ASTM A228 certificate of compliance; specify tensile strength range to support high-carbon classification
• Music wire often has polished finish—declare if burnishing applied, as it affects 'further worked' status
