HS Code 2517.30 – Tarred macadam

HS code 2517.30 is the 6-digit subheading for tarred macadam. It is used for asphalt macadam, bituminous macadam, tar-bound road aggregate, cold mix asphalt and hot mix asphalt (base course).

What HS 2517.30 covers

This HS code covers tarred macadam, a crucial material for road construction and maintenance. Tarred macadam consists of aggregates (like those in 251710 or 251720) that have been mixed with tar or bitumen, acting as a binder. This treatment enhances the material's durability, water resistance, and stability, making it ideal for road surfacing, paving, and repair. Importers are typically road construction companies, municipal authorities, and infrastructure developers who require ready-to-use paving materials. Exporters are often countries with well-developed petrochemical industries or specialized asphalt production facilities. The trade volume is heavily influenced by government infrastructure spending, urban development projects, and the availability of crude oil derivatives for bitumen production, making it a vital component of global civil engineering supply chains.

Codes often confused with 2517.30

Common mistake. This is distinct from 251710 (untreated aggregates) and 251720 (macadam from industrial waste) because of the specific tar/bitumen treatment, and also from finished asphalt products in 2715.

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).
