Incoloy 800H Hot-Rolled Alloy Steel Plate from China

Incoloy 800H is a high-nickel alloy steel plate (over 30% nickel) hot-rolled to a thickness of 4.75 mm or more and width exceeding 600 mm, not in coils and not further worked. It falls under HTS 7225.40.30.05 due to its high-nickel composition and specific hot-rolled form meeting the exact criteria of this subheading. Used primarily in high-temperature applications like heat exchangers.

Import Tips

Provide mill test certificates confirming high-nickel alloy composition (typically 30-35% Ni) and exact chemical analysis to verify classification

Ensure documentation specifies hot-rolled, not in coils, thickness ≥4.75 mm, and width ≥600 mm to avoid reclassification to thinner or narrower products
