More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If high-strength steel ≥0.5mm thick
Same high-strength spec but thicker dimension uses parallel subheading structure.
If chipper knife steel
Narrow composition tolerances in US note (f) classify specialized tool steels separately.
If imported as welded tubes
Post-import fabrication into tubes reclassifies from flat Chapter 72 to seamless/welded tubes in 73.04.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• TRIP steels need formability and strength test data to confirm US high-strength steel definition
• Verify in coil form at import; uncoiling may trigger parts classification
• Prepare alloy content analysis; trace elements shouldn't push into alloy steel headings
