Product classification
HS code for Prefabricated concrete beams: 6810.91
Cement, concrete or artificial stone, prefabricated structural components for building or civil engineering, whether or not reinforced.
Classification of prefabricated concrete beams under HS 6810.91
Prefabricated concrete beams are classified under HS code 6810.91 because they are structural components made of cement, concrete, or artificial stone. Chapter 68 covers articles of stone, plaster, and cement, and heading 6810 specifically addresses articles of cement or concrete, whether or not reinforced. The subheading 6810.91 is dedicated to prefabricated structural components for building or civil engineering. These beams are typically manufactured in a factory environment (precast) and then transported to construction sites for use in bridges, parking garages, or building frames. The classification is based on the material composition and the fact that they are finished structural elements rather than raw materials. Even if the beams contain steel reinforcement (rebar) or are prestressed, the concrete component determines the primary classification under this heading.

Codes often confused with 6810.91
Common mistake. These beams are often misclassified under 9406.90 (prefabricated buildings). However, 9406 is for entire buildings or kits, whereas 6810.91 is for individual structural components. Another common error is using 6810.11, which is for building blocks and bricks. While both are concrete, 6810.91 is specifically for engineering components like beams and pillars. Additionally, some importers try to classify them under 7308 if they are heavily reinforced with steel, but since the concrete provides the volume and form, 6810 remains the correct heading.
Top exporters and importers of HS 681091 (the code used for prefabricated concrete beams), 2025
In 2025, the largest exporter of HS 681091 (the code used for prefabricated concrete beams) in UN Comtrade data was Malaysia, with 17% of world exports; the largest importer in UN Comtrade data was Singapore, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
