Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coated with metallic or nonmetallic substances
Coated cold-rolled alloy steel classifies as further worked under 7225.99.
If imported as tubes/pipes rather than flat-rolled
Fabricated tubular products of alloy steel fall under Chapter 73 heading 7304.
If further worked by polishing or burnishing
Surface-finished alloy steel bars/rods classify under heading 7228.

Import Tips & Compliance
• Declare exact gauge tolerance; variations near 4.75 mm threshold require precise measurement
• Rust or discoloration doesn't reduce duties per Chapter 72 note; expect full duty assessment
• Document cold-rolling reduction ratio to distinguish from hot-rolled + annealed products
