Classification of gravel under HS 2517.10

Gravel is classified under HS code 2517.10. This heading is part of Chapter 25, which covers salt, sulfur, earths, stone, plastering materials, lime, and cement. The classification 2517.10 specifically identifies pebbles, gravel, and broken or crushed stone of a kind commonly used for concrete aggregates, road metalling, or railway ballast. The Harmonized System groups these materials together because they serve as the primary raw aggregates for the construction and infrastructure industries. The code applies regardless of whether the gravel is sourced from rivers or crushed from larger rock formations. Furthermore, the code includes shingle and flint. Even if the gravel has been heat-treated to improve its durability or color for specific architectural uses, it remains within this classification as long as it retains its character as a construction aggregate.

Codes often confused with 2517.10

Common mistake. Gravel is sometimes misclassified under 2505.10 or 2505.90, which are codes for natural sands. While sand and gravel are often found together, gravel is distinguished by its larger particle size. Another common error is using 2515 or 2516, which are reserved for dimension stones like marble or granite. If the stone is crushed into gravel, it must move to 2517.10. Additionally, decorative pebbles that have been highly polished may sometimes be argued into 6802, though 2517 remains the standard for bulk construction gravel.

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).
