HS Code 6810.11 – Cement, concrete or artificial stone; building blocks or bricks, whether or not reinforced
HS code 6810.11 is the 6-digit subheading for cement, concrete or artificial stone, building blocks or bricks, whether or not reinforced. It is used for concrete masonry units, hollow core blocks, solid concrete blocks, paving bricks and artificial stone bricks.
What HS 6810.11 covers
This HS code covers fundamental building materials: blocks and bricks made from cement, concrete, or artificial stone, whether or not they contain reinforcement. These goods are the backbone of construction projects globally, ranging from residential homes to commercial buildings and infrastructure. Due to their weight and bulk, international trade often occurs regionally, with significant movements between neighboring countries or within large economic blocs. Major importers and exporters include nations with robust construction sectors and readily available raw materials, such as aggregates and cement. Developing economies frequently import these basic building components to support rapid urbanization and infrastructure development, while developed nations might trade specialized or aesthetically unique blocks. Key considerations in trade include transportation costs, local building codes, and material specifications, which can vary significantly by region. The market is driven by housing demand, government infrastructure spending, and the availability of cost-effective production methods.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
