Last updated: August 2026 dataReplacement and service parts for industrial centrifuges and centrifugal dryers are widely traded inputs for pharmaceutical, chemical, food processing, and wastewater treatment operations. Classification hinges on whether a part is identifiable as solely or principally used with a centrifuge, as opposed to a general-purpose mechanical component. Importers should verify that parts are matched to the correct parent machine heading, since misclassification between centrifuge parts and filtering-equipment parts is a recurring audit issue.

The key test is whether the article is identifiable by its shape, construction, or design as solely or principally used with a centrifuge or centrifugal dryer. Generic fasteners, bearings, or seals that serve multiple machine types may be classified elsewhere; purpose-built bowls, rotors, and baskets typically remain within the centrifuge parts heading.
Depending on the country of origin, centrifuge parts may be subject to Section 301 tariffs. Importers should confirm the applicable tariff treatment for each specific origin before entry, as trade-remedy coverage can vary by component type and supplier country.
