HS Code for Portland cement

Portland cement, specifically the variety that is not white, is classified under HS code 2523.29. This falls within Chapter 25, which covers mineral products like earth, stone, and cement. Heading 2523 is reserved for hydraulic cements, whether or not colored. The classification is further refined into Portland cement (2523.2x). Within this group, a distinction is made between white Portland cement (2523.21) and other types (2523.29). Most grey Portland cement used in general construction, including Type I through Type V, falls under 2523.29. The classification depends on the chemical composition and the absence of specific whitening agents or high-purity limestone that would categorize it as white cement. Portland cement is produced by pulverizing clinker consisting essentially of hydraulic calcium silicates, usually containing one or more forms of calcium sulfate as an inter-ground addition. The "other" designation in 2523.29 captures the vast majority of industrial and construction-grade grey cements. Customs authorities require the chemical analysis to ensure the iron oxide content is high enough to disqualify it from the "white" category, which has a different tariff structure due to its higher production cost and specialized decorative uses.

Products Included

• Grey Portland cement (Type I, II, III, IV, V)
• Sulfate-resistant Portland cement
• Moderate heat of hydration Portland cement
• General purpose construction cement
• Oil-well cement (Portland-based)

Common Misclassification

The most frequent misclassification occurs with HS code 2523.21, which is strictly for white Portland cement, whether or not artificially colored. Another common error is using 2523.30 for aluminous cement (Ciment Fondu) or 2523.90 for other hydraulic cements like slag cement or pozzolanic cement, which have different chemical profiles than standard Portland cement.

FAQ

What is the HS code for Portland cement?

The HS code for standard (non-white) Portland cement is 2523.29.

Does this code include pre-mixed concrete?

No, pre-mixed or ready-mixed concrete is classified under HS code 3824.50, as it contains aggregates and additives beyond just the cement binder.
