Concrete & Mortar Mixers imports of $14.7M in June 2026 ran 34% above the year-to-date monthly average of $11.0M.
Last updated: June 2026 dataDrum mixers, pan mixers, and continuous-feed concrete mixers for construction and infrastructure projects are classified here, with Canada and China as the leading US import sources. The heading covers both truck-mounted transit mixers and stationary batch-plant equipment, though the US consolidates all variants into a single tariff line (8474310000). Goods from China are subject to Section 301 tariffs, making Canadian and Mexican supply — Mexico is the third-ranked source — strategically important for cost-sensitive procurement. Importers should distinguish this heading from self-propelled concrete mixer trucks, which are classified as motor vehicles rather than machinery.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A self-propelled transit mixer — where the mixing drum is mounted on a purpose-built truck chassis — is generally classified as a special-purpose motor vehicle under heading 8705 rather than under 8474.31. Heading 8474.31 applies to the mixing machinery itself, including stationary mixers and drum units designed to be mounted on separately imported vehicles. Importers should confirm whether they are importing the complete vehicle or the mixing unit alone.
Concrete mixers originating in Mexico may qualify for USMCA preferential tariff treatment if they satisfy the applicable rule of origin, which for machinery headings typically requires a tariff classification change and/or a regional value content threshold. Importers must secure a valid USMCA certification of origin and ensure the goods are not merely transshipped through Mexico from a non-USMCA country.
