Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not heat-treated
Non-heat-treated high-carbon round wire uses different subheading within same tariff line.
If imported as finished springs rather than wire
Fabricated springs from this wire classified under Chapter 73 as articles of iron/steel.
If alloy tool steel per note (e)
Tool steel compositions move to Chapter 72 alloy wire headings like 7228.

Import Tips & Compliance
• Submit mill test certificates confirming C67S composition and patenting heat treatment to verify HTS classification
• Measure diameter precisely; even slight deviation to ≥1.5 mm shifts to 7217.10.8035 subheading
• Declare as 'not further worked' beyond heat treatment/polishing per Chapter 72 definition to avoid Chapter 73
