Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If smaller dimensions
Narrower sections may classify as 'bars and rods' rather than structural shapes.
If phosphatized or oiled
Chemical surface treatments count as 'further worked' per Chapter notes, moving to 7228.80.
If carbon steel equivalent
Non-alloy versions use 7216.92 for similar hot-rolled shapes.

Import Tips & Compliance
• Submit chemical analysis reports proving >1.5% chromium or other alloying for 7228 classification
• Specify hot-rolled status; cold-formed channels go to 7216.92 or 7228.72
• Check for minimum width/thickness to avoid confusion with bars under 7228.30
