Manganese Oxide Nanoparticles from China
Manganese oxide nanoparticles are nano-sized particles of manganese dioxide (MnO2) used as catalysts in chemical reactions and water treatment applications. Despite their nanoscale form, they remain a chemically defined inorganic oxide of manganese. They are classified under tariff item 2820.90.00 as other manganese oxides, consistent with Chapter 28's coverage of separate chemically defined compounds.

Import Tips
• Confirm the nanoparticles are not coated or functionalized with organic materials, as that could shift classification to Chapter 38 or 29
• Include particle size distribution data and intended use in the commercial invoice to avoid delays
• Check if the product requires a permit under Canada's New Substances Notification Regulations if it is a new nanomaterial
