Product classification
HS code for Bitumen mixer: 8474.32
Machines, for mixing mineral substances with bitumen.
Classification of bitumen mixer under HS 8474.32
The classification of bitumen mixers under HS code 8474.32 is determined by the functional characteristics of the machinery. Chapter 84 of the Harmonized System encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Within this chapter, heading 8474 is dedicated to machinery used for sorting, screening, separating, washing, crushing, grinding, mixing, or kneading earth, stone, ores, or other mineral substances in solid form. Since bitumen is frequently mixed with mineral aggregates, such as gravel or sand, to produce asphalt for road construction, these specific machines are categorized under subheading 8474.32. This classification applies regardless of whether the machine is stationary or designed to be mounted on a trailer chassis, provided its primary function is the mixing of mineral substances with bitumen. The technical design usually involves a heating element to maintain the bitumen's viscosity and a mechanical stirring or tumbling mechanism to ensure a homogenous mixture with the mineral components.

Codes often confused with 8474.32
Common mistake. Bitumen mixers are frequently confused with concrete or mortar mixers, which are classified under HS code 8474.31. The distinction lies in the intended material; 8474.31 is for cement-based mixtures, while 8474.32 is specifically for bituminous mixtures. Additionally, general mixing machinery not specialized for mineral substances might be incorrectly filed under 8479.82, but 8474.32 takes precedence due to its higher specificity regarding mineral and bitumen processing.
Top exporters and importers of HS 847432 (the code used for bitumen mixer), 2025
In 2025, the largest exporter of HS 847432 (the code used for bitumen mixer) in UN Comtrade data was China, with 30% of world exports; the largest importer in UN Comtrade data was Russia, with about 6.0% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
