HS Code 2517.10 – Pebbles, gravel, broken or crushed stone; of a kind commonly used for concrete aggregates, for road metalling or for railway or other ballast, shingle and flint, whether or not heat-treated
HS code 2517.10 is the 6-digit subheading for pebbles, gravel, broken or crushed stone, of a kind commonly used for concrete aggregates, for road metalling or for railway or other ballast, shingle and flint, whether or not heat-treated. It is used for concrete aggregates, road gravel, railway ballast, crushed limestone and river pebbles.
What HS 2517.10 covers
This HS code covers bulk aggregates like pebbles, gravel, and broken or crushed stone, which are fundamental materials for large-scale infrastructure and construction projects. These materials are commonly used as concrete aggregates, for road metalling, and as railway or other ballast, and may or may not be heat-treated. The trade in these goods is driven by massive demand from the construction sector globally. Importers are typically construction companies, public works departments, and concrete manufacturers in regions lacking sufficient local aggregate resources or seeking specific material properties. Exporters are countries with abundant natural deposits and efficient quarrying operations. Logistics and transportation costs are paramount in this trade due to the high volume and relatively low unit value of these essential building blocks.

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).
