D2 Tool Steel Flat Bar
A flat bar made from D2 alloy tool steel, containing over 1.2% carbon and more than 10.5% chromium, used for making punches and dies. It falls under HTS 7228.60.10.60 as other bars and rods of tool steel (not high-speed steel) per Chapter 72 note (e). The rectangular cross-section classifies it as a bar rather than a wire or profile.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polished, coated, or otherwise further worked
Chapter 72 defines 'further worked' surface treatments (polishing, coating) that move product from 7228.60 to 7228.70.
If not meeting tool steel element requirements
Alloy steel bars without tool steel composition per Note (e) fall under other alloy steel bars in 7228.30.
If imported in straight lengths under 800mm and not hot-rolled
Cold-formed or finished bars/rods of alloy steel classify under Chapter 72 heading 7222.

Import Tips & Compliance
• Certify exact chemical composition at entry to meet U.S
• Note (e) tool steel definition (e.g
• >1.2% C and >10.5% Cr for D2)
• Provide mill test certificates showing it's not high-speed steel to avoid reclassification
• Watch for 'further worked' treatments like polishing that may shift to 7228.70 subheading
