Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of heat-resisting steel
Tool steels meeting heat-resisting steel definition in note (g) use separate statistical breakout.
If other rectangular alloy
Non-tool alloy steel rectangular semi-finished products classify under broader 7214 provisions.
If flat-rolled form
Tool steel produced as flat-rolled sheets/strips rather than rectangular billets moves to 7225.

Import Tips & Compliance
• Chemical certificates must explicitly reference HTS tool steel note compliance
• Scale drawings showing cross-section dimensions aid smooth customs clearance
• Maintain primary form—machining even on ends can reclassify as finished goods
