Nanocrystalline Cerium Dioxide
Nanocrystalline Cerium Dioxide consists of nano-sized CeO2 particles used in catalytic converters and UV blockers. It remains under tariff item 2846.10.00 as chemically defined cerium oxide, as particle size does not change classification unless the product is prepared for a specific use. The product meets Chapter 28 note 1 criteria, with no added substances that render it particularly suitable for a specific use.
