Commercial grades of calcium aluminate cement typically range from approximately 40% to over 70% Al₂O₃ content. Lower-alumina grades (around 40%) are used in general construction and sewer applications, while high-purity grades (70%+) are specified for demanding refractory and high-temperature industrial applications. The alumina content should be confirmed by the supplier's Certificate of Analysis and matched to the end-use specification before import.

Antidumping orders on cement are typically scope-specific and may not extend to aluminous cement, which is a chemically distinct product from Portland cement. Importers should request a formal scope ruling from the Department of Commerce if there is any ambiguity about whether an active order covers their specific product, rather than assuming coverage or exclusion.
