Palladium on barium sulfate is a heterogeneous catalyst consisting of finely divided palladium metal supported on a barium sulfate carrier, typically containing about 5% palladium by weight. It is used in selective hydrogenation reactions, such as the reduction of alkynes to alkenes, in pharmaceutical and fine chemical synthesis. This product is classified under tariff item 2843.90.00 as an inorganic compound of a precious metal (palladium) that is not a colloidal precious metal and is not otherwise specified, and it does not meet the definition of a separate chemically defined compound.

Import Tips
• Ensure the product is properly described on the commercial invoice as 'palladium on barium sulfate catalyst' with the palladium content clearly stated, as this affects classification and duty calculation
• Verify whether the palladium content requires an import permit under Canada's Nuclear Safety and Control Act or other regulations, although catalysts of this type are generally not controlled
• Keep records of the chemical composition and intended use, as the CBSA may request them to confirm the classification under 2843.90.00
