Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If explicit tool steel
D2 composition (>10.5% Cr, >1.2% C) meets tool steel note (e), specific subheading.
If ball-bearing steel specs
If C/Cr/Si ratios match ball-bearing note (h), different other alloy classification.
If ground to tool blanks
Further worked to specific tool dimensions classifies as hand tools.

Import Tips & Compliance
• Explicitly certify NOT tool steel if claiming this code; D2 typically 7224/7228 tool headings
• Square tolerance specs must match bar definitions vs. shapes
• Heat treatment records essential; certain conditions may qualify special steels
