7202.29.00 - Other

This HTS category, 7202.29.00, encompasses "Other" ferrosilicon not specifically defined in preceding subheadings. Ferrosilicon, generally, is an alloy of iron and silicon. This particular classification captures ferrosilicon products that do not fall under the more specific criterion of containing by weight more than 55 percent of silicon, which is addressed in the sibling category 7202.21.

Therefore, 7202.29.00 serves as a residual category for ferrosilicon alloys with a silicon content of 55 percent or less, provided they meet the general definition of ferrosilicon. This distinction is crucial for accurate tariff application, as the specific silicon content significantly influences the alloy's properties and intended uses, thereby affecting its classification and associated duties.

Within this "Other" ferrosilicon classification, further subdivisions exist to account for specific alloying elements. Subcategory 7202.29.00.10 distinguishes ferrosilicon containing by weight over 2 percent of magnesium, while 7202.29.00.50 captures all remaining ferrosilicon products that do not meet this magnesium threshold. These granular distinctions allow for precise classification based on the alloy's composition.
