Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coated or polished (further worked)
US Chapter notes define 'further worked' to include polishing, metal coating, or painting, shifting to 7226.99.
If not alloy steel (C ≥0.3% but lacks required elements)
Non-alloy steel cold-rolled products under 600mm classify in heading 7219, not Chapter 72 alloy steel.
If thickness ≤0.25 mm
Thickness threshold separates subheadings; ≤0.25mm moves to thinner flat-rolled category.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Declare exact chemical composition; 4340's nickel content distinguishes from tool steels in US Chapter 72 notes
• Avoid packaging that implies further processing; bulk coiled strip maintains 'not further worked' status
