Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing <0.6% carbon
Lower carbon content wire in same size/condition classified under separate chemical composition subheading.
If alloy tool steel per note (e)
Meets tool steel definition with specific carbon/chromium levels, shifts to alloy wire heading 7228.
If imported as helical springs
Pre-formed wire springs are classified as articles of iron/steel in Chapter 73 heading 7320.

Import Tips & Compliance
• Certify heat treatment method (e.g
• patenting process) matches tariff definition of 'heat treated' to prevent disputes
• Watch for rust/discoloration; no duty allowance per Chapter 72 notes, so ensure proper packaging
• Batch testing for diameter consistency avoids CBP measurement challenges at entry
