Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in irregularly wound coils rather than standardized
Bar/wire in coils with ≤0.6% carbon or different presentation uses Chapter 72 heading 7213.
If diameter less than 1.0 mm
Smaller diameter high-carbon heat-treated wire has separate statistical suffix.
If shaped into helical springs before import
Finished coil springs classified as stranded wire articles in Chapter 73.

Import Tips & Compliance
• Include ASTM A228 compliance certs showing tensile strength from heat treatment to support classification
• Watch for 'further worked' treatments like coating that would exclude from 7217.10 per Chapter notes
• Batch-test for uniformity; non-uniform carbon content risks audit and reclassification
