D2 Tool Steel Ground Round Bar
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not qualifying as tool steel per U.S. note (e)
Non-tool alloy steel bars with ground surfaces fall under general other alloy steel provisions in 7228.50.30.
If further worked with coatings or cladding
Surface treatments like metal coating or enameling constitute 'further worked' per chapter note, moving to 7228.30.
If maximum cross-sectional dimension under 18 mm
Bars with smaller dimensions, even ground tool steel, classified in adjacent statistical breakout.

Import Tips & Compliance
• 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
