UV-Blocking Cerium Oxide for Glass
UV-Blocking Cerium Oxide for Glass is a specialty cerium(IV) oxide compound doped to absorb ultraviolet radiation in automotive and architectural glass production. It qualifies under tariff item 2846.10.00 as a chemically defined cerium compound, with the doping not rendering it particularly suitable for a specific use beyond general UV absorption. The product meets Chapter 28 note 1 criteria for added substances that do not alter its fundamental chemical nature.

Import Tips & Compliance
• Provide a technical data sheet showing the doping level and confirm it remains a cerium oxide compound
• If the doping is with another rare-earth metal, note that mixtures may still fall under 2846.10.00 if they are of cerium compounds
• Be prepared to explain the UV-blocking function to the CBSA to avoid misclassification as a preparation
