Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the cement is in clinker form and not yet ground into powder
Cement clinkers are classified separately under the same heading, and aluminous clinker falls under 2523.10.00.
If the product is a hydraulic cement not specifically aluminous, such as a blend with other cement types
Other hydraulic cements not elsewhere specified are covered under this item.

Import Tips & Compliance
• Ensure the cement is in a crude or processed state (e.g
• ground or powdered) as per Chapter 25 Note 1, and avoid adding substances that make it suitable for a specific use beyond general use
• Declare the correct unit of measure (tonne or kilogram) based on the cement's weight excluding any dispersed water
• Keep documentation of the calcium aluminate composition to support classification under aluminous cement

Calcium Aluminate Cement Powder
Calcium aluminate cement powder is an aluminous cement used in rapid-hardening concrete and repair mortars, offering superior sulfate resistance and fast setting. It is classified under tariff item 2523.30.00 because its primary component is calcium aluminate, which defines aluminous cement.
Fondu Aluminous Cement
Fondu aluminous cement is a high-purity calcium aluminate cement used in specialty concretes and castables, known for quick setting properties. It qualifies under tariff item 2523.30.00 as an aluminous cement due to its calcium aluminate base.
High-Alumina Refractory Cement
High-alumina refractory cement is a hydraulic cement composed primarily of calcium aluminate, designed for high-temperature applications in furnaces and kilns. It falls under tariff item 2523.30.00 as aluminous cement, provided it is not a refractory mix excluded by Chapter 25 Note 2.
Rapid-Set Aluminous Cement Clinker
Rapid-set aluminous cement clinker is an intermediate product ground into finished cement, containing high aluminates. It is classified under tariff item 2523.30.00 whether in clinker or powder form, as the heading covers aluminous hydraulic cements in both forms.
Sulfuric-Resistant Aluminous Cement
Sulfuric-resistant aluminous cement is formulated for aggressive environments like sewers and wastewater structures, with high alumina content providing excellent resistance. It qualifies under tariff item 2523.30.00 as a hydraulic aluminous cement, as its composition and properties align with the heading.
