Sorting, Screening, Separating & Washing Machines for Minerals

CBP generally considers whether the machine is designed and equipped for movement between work sites — for example, mounted on wheels or a trailer chassis with towing provisions — versus permanently installed or requiring disassembly for relocation. Self-propelled or track-mounted screening plants are typically portable; fixed-foundation installations are stationary. The distinction affects which 10-digit tariff line applies and may influence state-level equipment tax treatment as well.

Machines from China in this heading may be subject to Section 301 tariffs. Importers sourcing from the United Kingdom, Canada, or Germany — the leading suppliers — should verify current tariff treatment, as trade-remedy exposure varies by country of origin and specific tariff line. A licensed customs broker can confirm the applicable duty rate and any active exclusions.
