7220.90.00 - Other

This HTS category, "Other," within the realm of flat-rolled stainless steel products with a width less than 600 mm, serves as a residual classification. It encompasses stainless steel flat-rolled products that do not fall under the specific criteria of other, more defined categories at this level. This generally includes stainless steel strip and sheets where the primary processing method or specific material composition has not been explicitly detailed in preceding headings.

Distinguishing this category from its siblings, such as "Not further worked than hot-rolled" and "Not further worked than cold-rolled (cold-reduced)," is crucial. Those sibling categories define the mechanical processing applied to the stainless steel. This "Other" category is for products where the hot or cold rolling process, as specifically defined, is not the sole or defining characteristic, or when other processing methods or inherent material properties are more relevant for classification.

Within this category, further subdivisions exist to refine the classification based on the specific chemical composition of the stainless steel. The subcategories differentiate based on the nickel content, specifically those containing more than 0.5 percent but less than 24 percent by weight of nickel, and an "Other" subcategory for stainless steels that fall outside this specific nickel range. These distinctions are vital for applying specific duty rates and trade regulations.
