7219.12.00.66 - Containing more than 1.5 percent but less than 5 percent by weight of molybdenum

This HTS classification, 7219.12.00.66, specifically covers flat-rolled products of stainless steel that are hot-rolled in coils, with a thickness ranging from 4.75 mm to 10 mm. The key distinguishing feature of this category is its molybdenum content, which must be more than 1.5 percent but less than 5 percent by weight. These products represent a particular grade of stainless steel, where molybdenum is added to enhance properties such as corrosion resistance and strength.

At the same level, sibling categories differentiate based on other compositional elements or broader "other" designations. For instance, 7219.12.00.71, also under the "Other" subdivision, likely covers stainless steel products that do not meet the specific molybdenum criteria outlined here. The classification process relies heavily on precise chemical composition to ensure accurate tariff application.

As a leaf node, 7219.12.00.66 does not have further subdivisions. Therefore, classification within this code is final once the specified conditions of material (stainless steel), form (hot-rolled coils), thickness (4.75 mm to 10 mm), and molybdenum content (greater than 1.5% and less than 5% by weight) are met. This ensures that shipments of these particular stainless steel coils are consistently categorized for trade purposes.
