7219.22.00 - Of a thickness of 4.75 mm or more but not exceeding 10 mm

This HTS category, 7219.22.00, specifically classifies flat-rolled products of stainless steel that have been hot-rolled but are not in coils. The defining physical characteristic for inclusion here is the material's thickness, which must be 4.75 mm or more but not exceed 10 mm. These are considered "not further worked" after the hot-rolling process, implying no additional treatments like cold-rolling, pickling, or polishing.

It is crucial to differentiate this category from its siblings based on thickness. Category 7219.21.00 covers similar hot-rolled, non-coiled stainless steel but with a greater thickness exceeding 10 mm. Conversely, 7219.23.00 and 7219.24.00 address thinner materials, with the former ranging from 3 mm up to (but not including) 4.75 mm, and the latter encompassing thicknesses less than 3 mm. Therefore, the 4.75 mm to 10 mm thickness range is the exclusive criterion for this specific sub-heading.

Within this category, further sub-classifications exist to refine the classification based on material composition and other characteristics. The subcategory 7219.22.00.05 distinguishes products made of high-nickel alloy steel, a specific type of stainless steel with distinct properties. All other stainless steel products meeting the thickness and processing criteria fall under the general "Other" subcategory, allowing for a comprehensive classification of various hot-rolled stainless steel flat products within this defined thickness range.
