High Alumina Cement from Japan

High alumina cement is a hydraulic cement produced from bauxite and limestone, capable of setting and hardening underwater or in air due to its aluminous composition. It falls under HTS 2523.90.00.00 as 'other hydraulic cements' distinct from Portland, slag, or supersulfate types. Primarily used in refractory applications and rapid-strength concrete.

Import Tips

Verify cement composition via lab analysis to confirm it meets 'hydraulic cement' criteria and isn't Portland (2523.21) or slag-based

Include manufacturer's specification sheets and chemical analysis reports in documentation to avoid misclassification

Check for country-specific quotas or anti-dumping duties on aluminous cements from certain origins
