Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If width four times thickness or more
Same tool steel rectangular semi-finished products but with wider cross-section fall under the parallel subheading.
If further worked and rectangular
Tool steel bars that are polished, coated, or otherwise surface-treated become 'further worked' under chapter notes and move to Chapter 72 finished bars.
If not qualifying as tool steel
Alloy steel rectangular bars not meeting tool steel element composition requirements in note (e) classify as other alloy steel under heading 7214.

Import Tips & Compliance
• Provide mill test certificate confirming tool steel composition per chapter note (e)(i) with >1.2% C and >10.5% Cr
• Measure and document cross-section dimensions to verify width <4x thickness for this specific subheading
• Avoid classification as finished bars under 7228 if further worked (polished/coated) per chapter definition
