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, 7019.72.40.30, specifically covers silica filament fabrics where the filaments themselves contain a silica content exceeding 93 percent. These fabrics are characterized by their high silica content, making them suitable for applications requiring high temperature resistance and inertness. The "622" indicator suggests specific regulatory or statistical tracking associated with this particular subclassification.

At this level of detail within the HTS, 7019.72.40.30 distinguishes itself from its sibling category, 7019.72.40.60, which is also designated as "Other" but presumably encompasses silica filament fabrics with a silica content of 93 percent or less, or other unspecified fabrics that do not meet the criteria for 7019.72.40.30. The key differentiator lies in the precise silica percentage of the filaments.

As this is a leaf node, there are no further subcategories. Therefore, classification within 7019.72.40.30 is definitive based on the material composition of the filaments. Importers and exporters should ensure they have accurate documentation confirming the silica content of the filaments used in the fabric to ensure correct customs declaration.
