Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polished or coated
Surface treatments like polishing qualify as 'further worked' per Chapter 72 notes, moving to 7226.91.
If width 600mm or more
Width threshold of 600mm places it in heading 7225 for wider flat-rolled alloy steel.
If not alloy steel per Chapter 72 note 1(k)
If alloy elements don't meet minimum thresholds, it's classified as non-alloy steel in Chapter 72 heading 7212.

Import Tips & Compliance
• Provide mill test certificate confirming alloy composition meets Chapter 72 definitions (e.g
• Cr+Mo content)
• Declare exact width/thickness; products >=600mm shift to 7225 heading
• Avoid 'further worked' treatments like coating/polishing to prevent reclassification to 7226.91+
