Coal-Based Impregnated Activated Carbon with Silver from United States
Coal-based activated carbon impregnated with silver to provide bacteriostatic properties for water filters. The silver impregnation is a secondary treatment that does not change the essential character of the activated carbon, so the product remains under tariff item 3802.10.00.

Import Tips
• Declare the silver content on customs documentation, as significant silver levels may trigger additional scrutiny
• The CBSA may require proof that the silver is present as an impregnation rather than a separate compound
• Ensure the product meets Canadian regulations for bacteriostatic water treatment materials
