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
