6902.20.50 - Other
Sub-classifications
Overview
HTS 6902.20.50 encompasses "Other" refractory ceramic constructional goods. This category is specifically for those articles, other than bricks, that are designed to withstand high temperatures and are composed of more than 50% by weight of alumina, silica, or a mixture of these products. These are typically manufactured for use in furnaces, kilns, and other industrial applications where extreme heat resistance is a critical requirement.
This code differentiates itself from its sibling category, 6902.20.10 "Bricks," by excluding any items that are shaped or intended for use as individual bricks in construction. Therefore, while both fall under the broader heading for refractory constructional goods containing high levels of alumina or silica, 6902.20.50 is for non-brick forms like blocks, tiles, or other molded refractory shapes.
Within the "Other" category (6902.20.50), further subdivisions exist to refine the classification based on specific chemical composition. The subcategory 6902.20.50.10 specifically designates items where alumina is the predominant component (above 50%), while 6902.20.50.20 covers all other refractory ceramic constructional goods within this heading that do not meet the specific alumina-based criterion but still contain over 50% of alumina, silica, or their mixtures.
