Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If Cr 10.5%+ making it stainless
Stainless definition in note 1(f) overrides heat-resisting note 1(g).
If burnished/polished surface
Polishing = further worked treatment per Chapter 72 definition.
If imported as parts of heat exchangers
End-use as machinery parts may shift to Chapter 84/85 functional headings.

Import Tips & Compliance
• Specify low carbon (<0.3%) and Cr range to distinguish from stainless
• Pack to prevent surface damage; no duty allowance for rust per notes
• End-use declaration for heat-resisting applications may affect rulings
