Tarred macadam.
Classification of tarred macadam under HS 2517.30
Tarred macadam is classified under HS code 2517.30. This heading is situated within Chapter 25, which encompasses salt, sulfur, earths and stone, and plastering materials. Specifically, heading 2517 covers pebbles, gravel, broken or crushed stone, of a kind commonly used for concrete aggregates, for road metalling, or for railway or other ballast. Tarred macadam refers to a specific road-building material consisting of crushed stone or aggregate that has been mechanically mixed with a binder of tar or bitumen. The classification is based on the fact that the mineral aggregate remains the primary component by weight and volume, even though it has been treated with a bituminous binder to improve its performance as a paving material. This code is essential for the construction and infrastructure sectors, as it distinguishes raw crushed stone from stone that has been pre-treated for immediate use in road surfacing or 'tarmac' applications.

Codes often confused with 2517.30
Common mistake. Tarred macadam is frequently confused with HS code 2715.00, which covers bituminous mixtures based on natural asphalt, natural bitumen, or petroleum bitumen. The distinction is that 2517.30 is for stone that has been 'tarred,' whereas 2715.00 is for the bituminous mixtures themselves (like mastics or cut-backs). It is also occasionally confused with HS code 3824.99, which covers various chemical products and preparations, but 2517.30 is the more specific heading for treated mineral aggregates.

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).
