Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ground or polished
Further worked (polished) tool steel classifies in 7228.70 as 'other bars/rods'.
If circular cross-section under 80mm and not tool steel
Non-tool alloy steel hot-rolled bars/rods shift to 7213 if lacking specific tool steel composition.
If ball-bearing steel
Specific ball-bearing steel per note (h) uses 7227.90.20 instead of general tool steel.

Import Tips & Compliance
• Label shipments clearly as 'not tempered, not treated' with heat analysis to confirm tool steel specs
• Avoid common pitfall of classifying as carbon steel; verify alloy elements exceed note (e) criteria
• Use proper coil packaging to prevent damage claims disallowed for pre-entry rust per chapter note
