HS Code 2523.29 – Cement; portland, other than white, whether or not artificially coloured
HS code 2523.29 is the 6-digit subheading for cement, portland, other than white, whether or not artificially coloured. It is used for ordinary Portland cement (OPC), portland blast-furnace slag cement, portland fly-ash cement, sulfate-resisting Portland cement and low-heat Portland cement.
What HS 2523.29 covers
This category encompasses the vast majority of Portland cement traded globally, serving as the fundamental binder in concrete and mortar for infrastructure, residential, and commercial construction. It's a high-volume, relatively low-margin commodity, with international trade primarily driven by regional supply-demand imbalances, logistical efficiencies, and production costs. Major exporters are typically countries with abundant limestone reserves, efficient production capacities, and access to shipping routes, while importers include rapidly developing economies or those with insufficient domestic production. Environmental regulations, including carbon pricing mechanisms like CBAM, are increasingly influencing its international trade dynamics, pushing for more sustainable production and transport methods across the supply chain.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
