7202.21.75.00 - Containing by weight more than 80 percent but not more than 90 percent of silicon

This HTS classification, 7202.21.75.00, specifically identifies ferrosilicon alloys that contain a precise percentage of silicon by weight, falling between more than 80 percent and not more than 90 percent. Ferrosilicon, in general, is an alloy of iron and silicon, crucial in various industrial processes. This particular subcategory distinguishes itself by its high silicon content, making it a specialized product within the broader ferrosilicon market.

The primary differentiator for this category lies in its silicon content, as explicitly stated in its description. It is distinct from its sibling category, 7202.21.75.00, which covers ferrosilicon with a silicon content of more than 55 percent but not exceeding 80 percent. It also differs from the other sibling category, 7202.21.90.00, which encompasses ferrosilicon containing more than 90 percent silicon. These distinctions are critical for accurate tariff application and depend solely on the precise weight percentage of silicon present in the alloy.

As this node represents a leaf node in the HTS classification structure, there are no further subcategories to introduce. The classification is fully defined by the stated silicon content. Examples of products falling under this category would be specific grades of ferrosilicon used in specialized applications such as the production of stainless steel, the manufacturing of silicon metal, or as a reducing agent in metallurgical processes where a precise high silicon content is required to achieve desired outcomes.
