Supersulfated Cement Powder from Germany
Supersulfated cement powder is a hydraulic cement that develops strength through sulfate reactions, typically composed of granulated blast furnace slag, calcium sulfate, and a small amount of Portland clinker. It offers good resistance to chemical attack and is used in marine and industrial environments. This product is classified under tariff item 2523.90.00 as 'other hydraulic cement' because it does not meet the specific definition of supersulphate cement under the subheading, which has distinct compositional requirements.

Import Tips
• Verify that the product's sulfate content and composition do not align with the specific definition of supersulphate cement under tariff item 2523.90.00; if they do, it may be classified elsewhere
• Provide a detailed chemical analysis to the CBSA, including the percentage of slag, sulfate, and clinker
• If the cement is for marine use, check for any additional Canadian import permits related to construction materials
