Last updated: August 2026 dataVibratory compaction equipment — including single-drum and tandem rollers, pneumatic-tire rollers, and soil tampers — is essential to pavement and embankment construction and is subdivided in the US schedule by operating principle and condition. Vibratory new units enter under 8429400020, other new types under 8429400040, and used or rebuilt equipment under 8429400060. Germany leads US imports in this heading, consistent with the strong global market position of German compaction-equipment manufacturers, with Brazil and Italy also significant sources.

A vibratory roller incorporates an eccentric-weight or hydraulic mechanism that generates oscillating compaction force through the drum, whereas a static roller relies solely on deadweight. The distinction is relevant because vibratory new units are specifically enumerated under 8429400020, while static and other non-vibratory new rollers fall under the residual new-unit line 8429400040.
Potentially yes, but the importer must be prepared to demonstrate the machine's prior US use or export history to support any applicable duty treatment. If the unit was substantially rebuilt abroad, CBP may scrutinize country-of-origin and value. Consulting a licensed customs broker before re-importation is advisable.
