Overview
This HTS category, 2606.00.00.30, specifically covers calcined bauxite that is intended for use in the production of refractory materials. Refractories are materials designed to withstand high temperatures and chemical attack, commonly used in furnaces, kilns, and other high-heat industrial applications. The "refractory grade" designation indicates that the bauxite has undergone specific processing, such as calcination, to achieve the necessary physical and chemical properties for these demanding uses.
This category is distinguished from its sibling, 2606.00.00.60, which covers "Other" calcined bauxite. While both fall under the broader classification of calcined bauxite, the ".30" subheading is reserved for bauxite that meets the technical specifications and quality standards required for refractory applications. The ".60" subheading would encompass calcined bauxite used for other purposes, such as in the production of aluminum metal or other industrial chemicals, where the requirements for purity and physical form may differ.
As this is a leaf node within the HTS classification, there are no further subcategories. Classification under 2606.00.00.30 relies on the importer or exporter demonstrating that the calcined bauxite meets the established criteria for refractory grade. This may involve specifying the intended end-use, providing technical specifications regarding alumina content, silica content, and other impurities, or presenting certification from the producer confirming its suitability for refractory manufacturing.
