7202.93.80.00 - Other

This HTS category, 7202.93.80.00, specifically classifies "Other" ferroniobium. Ferroniobium is an alloy of iron and niobium, primarily used in the steel industry as an additive to enhance the strength, toughness, and weldability of steel. This particular subheading captures ferroniobium that does not fit the specific compositional criteria outlined in its sibling category.

The key differentiator from its sibling, 7202.93.40.00, lies in the percentage of phosphorus, sulfur, and silicon. This "Other" category encompasses ferroniobium containing by weight 0.02 percent or more of phosphorus or sulfur, or 0.4 percent or more of silicon. Therefore, when classifying ferroniobium, a precise analysis of its elemental composition, particularly for phosphorus, sulfur, and silicon, is crucial to determine the correct subheading.

As this is a leaf node in the HTS classification system, there are no further subdivisions under 7202.93.80.00. Consequently, all ferroniobium that meets the criteria of containing higher percentages of phosphorus, sulfur, or silicon, and is not specifically classified elsewhere, will fall under this designation. Importers and exporters should consult detailed laboratory analyses to ensure accurate classification and compliance with customs regulations.
