Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If universal mill plate specs
If width 150-1250 mm, thickness ≥4 mm, not in coils, fits US Note 72(b) definition.
If tool steel alloy
Meets tool steel element criteria in US Note 72(e), e.g., specific C/Cr combinations.
If low alloy content
Below alloy steel thresholds, treated as carbon steel hot-rolled coil.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Certify not tool steel per US Note 72(e); typical 4130 has <1.2% C and <10.5% Cr
• Ensure invoice specifies 'in coils' to distinguish from universal mill plate under 7225.11
• Monitor for AD/CVD orders on specific alloy grades from certain countries
