Import Tips

Provide mill test certificate confirming alloy composition (e.g

Cr 0.8-1.1%, Mo 0.15-0.25%) to verify not stainless or high-strength steel

Ensure accurate thickness measurement (<4.75 mm) and width (≥600 mm) documentation to avoid reclassification to 7225.30.30 or narrower products

Declare as 'not further worked than hot-rolled' with surface inspection reports; any polishing or coating shifts to 7225.99
