Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fire-clay with higher alumina but kaolinitic properties
Clays with refractory characteristics but lower purity may fall under fire-clays heading 2508.
If pebbles, gravel, broken or crushed stone containing kaolin for aggregates
Chapter note prioritizes heading 2517 for any pebbles or broken materials over pure clays.
If sold as 'earth colors' with iron oxide impurities
Kaolin with significant colorants may classify under mineral earth colors in heading 2530.

Import Tips & Compliance
• Provide mineral assay reports confirming high kaolinite content (>50%) to distinguish from other clays
• Check for anti-dumping duties from specific origins like Brazil or China on kaolin products
• Use UN non-hazardous classification but note dust hazards in MSDS for customs review

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.
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.
Air-Floated Kaolin
Kaolin clay processed by air flotation to remove coarse particles, used in paints and rubber. Remains under HTS 2507.00.00.00 as physical processing doesn't change natural clay classification.
Kaolin Calcined for Paint Extender
Structurally modified calcined kaolin providing matting and opacity in architectural paints. HTS 2507.00.00.00 applies as calcination alone doesn't constitute chemical change.
