U.S. imports of machinery for public works, building & construction (HS 847910) totaled $48.4M in April 2026, traded with 34 countries.
Importers of Machinery for Public Works, Building & Construction paid $5.0M in duties in April 2026 — an effective duty rate of 11% on $45.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataPavers, finishers, and spreaders for concrete and bituminous materials dominate this heading, alongside a broad catch-all line for other public works and building machinery. The US schedule distinguishes concrete pavers (8479100040), bituminous material pavers (8479100060), and residual public works machinery (8479100080), making precise classification critical for road-construction equipment importers. Germany leads supply, with Canada and Finland also significant sources, reflecting European engineering strength in heavy construction equipment. Importers should verify whether specific machines fall here or under Chapter 84 headings for earthmoving or lifting equipment, as misclassification is a common audit trigger.

The US tariff schedule separates pavers, finishers, and spreaders designed for concrete (8479100040) from those designed for bituminous materials such as asphalt (8479100060). Classification turns on the machine's primary design and the material it is engineered to handle, not incidental capability. When a machine is dual-purpose, CBP guidance and the machine's technical specifications should be reviewed with a licensed customs broker.
Equipment that primarily moves or excavates earth may fall under Chapter 84 headings for bulldozers, graders, or excavators rather than under 847910. CBP applies the essential character and principal function tests; importers should document the machine's design intent and primary commercial use to support the chosen classification.
