High Alumina Cement from United States
High alumina cement is a hydraulic cement produced from bauxite and limestone, offering rapid hardening and high-temperature resistance. It sets and hardens both in air and underwater, making it suitable for refractory and marine applications. This product is classified under tariff item 2523.90.00 as 'other hydraulic cement' because it is not specifically listed as aluminous cement in the subheading, which covers only certain types.

Import Tips
• Ensure the product is not classified as aluminous cement under tariff item 2523.30.00, which may have different duty rates; verify the alumina content and composition
• Provide a certificate of analysis to the CBSA to confirm the cement's hydraulic properties and raw materials
• If the cement is for refractory use, check if additional import restrictions apply under Canadian environmental or safety regulations
