Overview
This HTS category, 6902.20.10.10, specifically classifies refractory bricks that are composed of more than 50 percent alumina (Al2O3). These bricks are designed to withstand high temperatures and are crucial components in furnaces, kilns, and other industrial heating applications where extreme heat resistance is paramount. The alumina content provides excellent refractoriness and resistance to chemical attack at elevated temperatures.
Within the broader classification of refractory bricks containing more than 50 percent alumina, silica, or a mixture thereof, this subcategory distinguishes itself by focusing solely on "bricks." It stands in contrast to its sibling category, 6902.20.10.20, which is designated for "Other" refractory constructional goods within this alumina/silica-rich group. Therefore, if the refractory ceramic constructional good is in the form of a brick and primarily consists of alumina (over 50% by weight), it falls under this specific classification.
As this is a leaf node within the HTS structure, there are no further subcategories. Classification under this code hinges on the material composition (primarily alumina) and the product form (brick). Therefore, careful verification of the weight percentage of alumina is essential for accurate classification, ensuring that the product meets the specified threshold of over 50 percent.
