Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the nanoparticles are surface-treated with organic agents for dispersion in specific matrices
Surface-treated inorganic powders may be classified as chemical preparations under Chapter 38.

Import Tips & Compliance
• Confirm the nanoparticles are not coated or functionalised with organic compounds, which would exclude them from Chapter 28
• Provide particle size distribution and purity data
• Ensure the powder is not classified as a hazardous material requiring special permits
