Incoloy 800H Hot-Rolled Alloy Steel Plate
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If subjected to further surface working like polishing or coating
Chapter notes define 'further worked' to include polishing, coating, etc., moving it from hot-rolled not further worked to other alloy steel categories.
If thickness under 4.75 mm
Thinner high-nickel alloy plates fall under the separate thickness subheading within the same hot-rolled category.
If not qualifying as alloy steel (less than required alloy elements)
If nickel content doesn't meet alloy steel thresholds per chapter definitions, it reverts to non-alloy steel flat-rolled products.

Import Tips & Compliance
• 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
