Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made up into tubes/pipes
Fabricated into seamless tubes changes from flat-rolled to tubes heading 7304.
If thinner than 4.75 mm
Same specs but thickness <4.75 mm uses 7225.40 subheading.
If bars rather than flat-rolled
Rectangular cross-section >150mm wide classifies as bars in 7213 if not flat-rolled.

Import Tips & Compliance
• Submit heat analysis showing 0.8-1.1% Cr, 0.15-0.25% Mo to confirm alloy status
• Ensure no phosphatizing or other chemical treatments - violates 'not further worked'
• Bulk import packaging must not alter classification to retail sets
