Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not in coils (straightened)
Straight lengths of same spec stainless rods classify under different 7221 subheading.
If parts of heat exchangers
If imported as specified heat exchanger parts, principal use provisions apply over material form.
If razor blade steel per note (d)
Special narrow stainless for blades has separate wire rod classification.

Import Tips & Compliance
• Distinguish from heat-resisting steel (note g); provide full composition to confirm classification
• Coil integrity important; damaged coils risking straightening reclassification
• Label clearly as industrial raw material to avoid consumer goods headings
