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 code, 6902.90.10.10, specifically classifies "Clay" bricks within the broader category of refractory ceramic constructional goods. These are bricks manufactured from clay or clay-based materials that are designed to withstand high temperatures and resist thermal shock, making them suitable for use in furnaces, kilns, incinerators, and other high-heat environments. The defining characteristic is their refractory nature, intended for constructional applications where thermal resistance is paramount.

Distinguishing this category from its sibling, 6902.90.10.20, which covers "Other" refractory bricks, blocks, tiles, and similar goods (excluding those of siliceous fossil meals or similar siliceous earths), is crucial. While both fall under the general umbrella of refractory constructional ceramics, this specific code is for bricks made primarily from clay. The sibling category would encompass other forms like blocks or tiles, or bricks made from different refractory compositions not solely based on clay.

As this is a leaf node, there are no further subcategories to introduce. Classification under this HTS code is therefore determined by the material composition (clay-based) and the form factor (bricks) of the refractory ceramic constructional goods. Therefore, goods that are not primarily made of clay, or are not in the form of bricks, would not be classified under 6902.90.10.10.
