Pozzolanic Hydraulic Cement Blend from Germany
Pozzolanic hydraulic cement blend is a composite of Portland clinker (less than 50%), fly ash, and gypsum, which sets through pozzolanic reactions. It offers a low-carbon alternative for concrete production with good durability. This product falls under tariff item 2523.90.00 as 'other hydraulic cement' because its composition does not meet the specific definitions of Portland, aluminous, slag, or supersulphate cement.

Import Tips
• Clearly document the percentage of Portland clinker (must be less than 50%) to avoid classification as Portland cement under tariff item 2523.29.00
• Provide a certificate of analysis showing the pozzolanic activity and composition to the CBSA
• If the fly ash is sourced from coal combustion, check for any environmental import restrictions in Canada
