Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If further worked with polishing or coating
Surface treatments like polishing move it from semi-finished (7224) to bars/rods further worked (7228).
If square cross-section (width <4x thickness)
Square tool steel billets fall under separate subheading excluding flat rectangular shapes.
If not meeting tool steel chemical composition
Non-tool alloy steel semi-finished products classify under other alloy steel headings in 7218.

Import Tips & Compliance
• Provide mill test certificate confirming tool steel composition per US note (e.g
• >1.2% C, >10.5% Cr for D2)
• Verify dimensions meet 'width at least four times thickness' via caliper measurements before entry
• Avoid classifying as finished if further machining required; semi-finished status affects duty
