About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification, 3815.90.10.00, specifically covers other catalytic preparations, not elsewhere specified or included, that consist wholly of inorganic substances. The defining characteristic of this category is that the active catalytic components are limited to bismuth, tungsten, or vanadium. These substances are employed in various chemical reactions to increase reaction rates or enable reactions that would otherwise not occur.

Within the broader category of "Other" reaction accelerators and catalytic preparations consisting wholly of inorganic substances, this subcategory is distinguished by its precise material composition. Its sibling categories, 3815.90.20.00 and 3815.90.30.00, differentiate based on the presence of mercury or molybdenum, or a combination of other inorganic elements, respectively. Therefore, to correctly classify a product under 3815.90.10.00, it is essential to confirm that the inorganic components consist solely of bismuth, tungsten, or vanadium, and do not include mercury, molybdenum, or other inorganic substances outside of these specified elements. As this is a leaf node, there are no further subdivisions; classification is finalized based on the stated material composition.
