Calcined Kaolin Powder
High-purity calcined kaolin powder used as a filler in paper production to enhance brightness and opacity. This product falls under HTS 2507.00.00.00 as it is calcined kaolin clay, processed by heating to remove water without altering its fundamental mineral structure.
Hydrous Kaolin Clay
Natural hydrous (uncalcined) kaolin clay mined and minimally processed for use in ceramics and refractories. Classified under HTS 2507.00.00.00 as other kaolinic clays, whether or not calcined, covering raw forms.
Kaolin Clay for Paper Filler
Fine-particle kaolin clay specifically graded for use as a coating and filler in paper manufacturing. Falls under HTS 2507.00.00.00 as kaolinic clay meeting particle size specs but remaining natural mineral product.
Ball Clay (Kaolinic)
Plastic ball clay with high kaolinite content used in sanitaryware and tableware production. HTS 2507.00.00.00 covers this kaolinic clay despite its higher plasticity compared to pure kaolin.
Kaolin for Ceramic Sanitaryware
Premium kaolin selected for low iron content in manufacturing bathroom fixtures and tiles. Classified under HTS 2507.00.00.00 as other kaolinic clays meeting ceramics industry purity standards.
