Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-coated onto paper substrate before import
Kaolin applied to paper becomes part of paper product under Chapter 48, not raw clay.
If when dispersed in liquid as inorganic color lake preparation
Liquid pigment dispersions containing kaolin classify as coloring matter in Chapter 32.

Import Tips & Compliance
• Particle size distribution certificates essential to prove suitability for paper vs other end-uses
• Confirm no chemical delamination treatment which would shift to Chapter 28 preparations
• Bulk shipments common; ensure proper ventilation markings for fine powder dust control
