White Supersulfate Cement
White supersulfate cement combining Portland clinker with high sulfate content for sulfate resistance, maintaining white colour through low-iron components. Although supersulfate cement is generally in heading 25.23, tariff item 2523.21.00 specifically covers white cement, and this product's white hydraulic nature qualifies it here.

Architectural White Cement
Premium white Portland cement engineered for exposed architectural concrete, with optimized fineness for smooth finishes and low heat of hydration. Its high whiteness and hydraulic properties qualify it under tariff item 2523.21.00 as white cement, whether or not artificially coloured.
Artificially Colored White Cement - Ivory Shade
White Portland cement artificially coloured to an ivory shade using iron-free pigments, designed for precast elements requiring specific architectural palettes. The artificial colouring is explicitly covered by tariff item 2523.21.00, which includes white cement whether or not artificially coloured.
Decorative White Cement with Blue Tint
White cement with blue pigment for artistic terrazzo and stained concrete applications, retaining hydraulic setting properties. Tariff item 2523.21.00 explicitly covers white cement that is artificially coloured, making this product classifiable here.
High Early Strength White Cement
White Portland cement formulated for rapid setting in precast production, achieving high strength within hours while preserving white colour. Its hydraulic properties and white appearance place it under tariff item 2523.21.00 as white cement, regardless of early strength characteristics.
White Cement Clinkers
White cement clinkers, intermediate nodules from kiln firing of low-iron raw materials, ground into finished white Portland cement. As clinkers are the crude form of white cement, they fall under tariff item 2523.21.00, which covers white cement in clinker form.
White Portland Cement
White Portland cement produced from raw materials with low iron content, resulting in its characteristic white colour, suitable for architectural and decorative applications. This product squarely meets the description of tariff item 2523.21.00 for white cement.
