D2 Tool Steel Ground Round Bar from Japan
A 20 mm diameter round bar made from D2 alloy tool steel, cold-finished with ground surfaces for precision machining applications. Classified under HTS 7228.50.10.60 as tool steel (meeting U.S. note (e)) bars of round cross-section with maximum dimension over 18 mm and ground surfaces, not further worked beyond cold-finishing. Ideal for dies, punches, and shear blades requiring high wear resistance.

Import Tips
• Certify tool steel composition meets U.S. note (e) criteria (e.g
• >1.2% C & >10.5% Cr for D2) with mill test reports to avoid reclassification
• Document cold-finishing process (ground/milled only, no coatings) as 'further worked' treatments trigger different subheadings
• Verify cross-section max dimension ≥18 mm; smaller bars shift to other statistical suffixes
