Classification of crushed stone under HS 2517.10
Crushed stone is classified under HS code 2517.10. This classification falls within Chapter 25, which covers salt, sulfur, earths, and stone, as well as plastering materials, lime, and cement. Heading 2517 specifically addresses pebbles, gravel, and broken or crushed stone of a kind commonly used for concrete aggregates, for road metalling, or for railway or other ballast. The classification is based on the physical state of the material and its intended use in construction and infrastructure. According to the Explanatory Notes to the Harmonized System, this heading includes stones that have been broken or crushed to make them suitable for use as aggregates. The material can be composed of various rock types, such as granite, basalt, or limestone, but once it is crushed for these specific industrial purposes, it is grouped under 2517.10. This remains true even if the stone has been heat-treated. The size and shape of the crushed stone are generally irregular, distinguishing it from dimension stone that has been cut or sawn into specific blocks or slabs. This classification is essential for the global trade of raw construction materials and is used by customs authorities to monitor the flow of aggregates used in public works.

Codes often confused with 2517.10
Common mistake. Crushed stone is frequently misclassified under the specific headings for the source rock, such as 2516 for granite or 2515 for marble. However, if the stone is crushed for use as aggregate, 2517.10 takes precedence. Another common error is confusing it with macadam (2517.20), which consists of crushed stone specifically mixed with tar or similar binders. Additionally, limestone flux used in steelmaking is classified under 2521.00 rather than 2517.10.

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).
