Kaolin for Ceramic Sanitaryware
Kaolin for ceramic sanitaryware is a high-purity, low-iron kaolin selected for manufacturing bathroom fixtures and tiles. It qualifies as 'other kaolinic clays' under tariff item 2507.00.00, provided it is not processed beyond washing, crushing, or similar physical methods.

Import Tips & Compliance
• Maintain records of the clay's iron content and particle size to demonstrate it is a natural kaolin product
• If the kaolin is blended with other clays or additives, check whether it remains classifiable here or under a mixed product heading
Related Products under Tariff item 2507.00.00
Air-Floated Kaolin
Air-floated kaolin is a naturally occurring clay processed by physical air separation to remove coarse particles, leaving a fine powder used in paints and rubber. This mechanical treatment does not alter the mineral's chemical structure, so it remains classifiable as kaolin under tariff item 2507.00.00.
Ball Clay (Kaolinic)
Ball clay is a highly plastic, kaolinitic sedimentary clay used in sanitaryware and tableware. Despite its higher plasticity and organic content compared to pure kaolin, it qualifies as 'other kaolinic clays' under tariff item 2507.00.00 because it is not excluded by chapter notes and remains a natural clay.
Calcined Kaolin Powder
Calcined kaolin powder is produced by heating natural kaolin to drive off water and alter its crystalline structure, a process explicitly allowed by the tariff text. It is used as a filler in paper to enhance brightness and opacity, and remains within tariff item 2507.00.00 as calcined kaolin.
English China Clay (Kaolin)
English china clay, also known as kaolin, is a high-purity, naturally occurring clay prized for its whiteness in bone china production. As the archetypal kaolin, it falls directly under tariff item 2507.00.00, which covers kaolin whether or not calcined.
Hydrous Kaolin Clay
Hydrous kaolin clay is natural, uncalcined kaolin that has been mined and minimally processed, such as drying or grinding, for use in ceramics and refractories. The tariff item explicitly covers kaolin 'whether or not calcined,' so the uncalcined form is included as long as processing stays within chapter note 1 limits.
Kaolin Calcined for Paint Extender
Calcined kaolin used as a paint extender is produced by heating kaolin to modify its particle structure, providing matting and opacity in architectural paints. This thermal treatment is expressly permitted by tariff item 2507.00.00, which covers calcined kaolin, and does not constitute a chemical change.
