Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other than round cross-section
Non-round high-carbon wire (e.g., square) classifies under 7214 shapes.
If diameter 2.0 mm or more
Thicker wire in same category moves to larger diameter statistical suffixes.
If shaped into spring forms before import
Pre-formed springs become structures/articles under heading 7308.
