Overview

This HTS classification covers ferrosilicon alloys that contain by weight over 2 percent of magnesium. Ferrosilicon, in general, is an alloy of iron and silicon, crucial for various industrial applications, particularly in the steelmaking and foundry industries. The specific inclusion of over 2% magnesium distinguishes these particular ferrosilicon products.

The primary distinction for this category lies in its magnesium content. At this level of the HTS hierarchy, sibling category 7202.29.00.50, also classified as "Other" ferrosilicon, would encompass those alloys that do not meet the specific criterion of exceeding 2% magnesium. Therefore, accurate determination of the magnesium content is the key differentiating factor for classification under 7202.29.00.10.

As this is a leaf node in the HTS classification system, there are no further subcategories. Classification within 7202.29.00.10 is determined solely by the presence of ferrosilicon meeting the specified magnesium percentage. Practical classification will rely on laboratory analysis or manufacturer specifications to confirm the weight percentage of magnesium.
