7219.90.00.20 - Containing more than 1.5 percent but less than 5 percent by weight of molybdenum

This HTS classification, 7219.90.00.20, specifically identifies flat-rolled products of stainless steel that meet particular chemical composition requirements. The defining characteristic of this category is that the stainless steel must contain a specific range of molybdenum by weight: more than 1.5 percent but less than 5 percent. These products fall under the broader scope of "Other" flat-rolled stainless steel products, indicating they do not fit into more precisely defined subcategories within the "Other" group at the 10-digit level.

When classifying these products, it is crucial to distinguish them from their sibling categories at the same level. In this instance, the sole sibling category is 7219.90.00.25, also designated as "Other." The key differentiator lies solely in the molybdenum content. While 7219.90.00.25 likely covers stainless steel flat-rolled products within the "Other" classification that *do not* meet the molybdenum percentage specified here, this category exclusively covers those within the 1.5% to 5% molybdenum range.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is final based on the product meeting the description of being flat-rolled stainless steel with a width of 600 mm or more, and its specific molybdenum content falling within the stated range. Examples of such products could include specialized stainless steel sheets or plates used in high-corrosion environments or applications requiring enhanced mechanical properties, where molybdenum addition is critical for performance.
