Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If high-strength steel per US Note (a)
Qualifies as high-strength if yield point meets minimums (275 MPa <3mm or 355 MPa ≥3mm), moving to specific high-strength subheading.
If hot-rolled instead of cold-rolled
Hot-rolled alloy steel flat products fall under Chapter 72 heading 7225 before cold-reduction process.
If width 300-600 mm
Width dimension separates subheadings within 7226.92; 300mm+ shifts from .8050 to .30 series.

Import Tips & Compliance
• Provide mill test certificates confirming alloy composition meets AISI 4130 specs and cold-rolled status to avoid reclassification
• Measure exact width and thickness at time of entry; discrepancies can trigger audits under Chapter 72 notes
• Ensure no surface treatments like polishing or coating applied, as 'further worked' per US notes shifts to 7226.99
