The key distinction is the drying mechanism: centrifugal dryers remove moisture through high-speed spinning (centrifugal force), while conventional tumble dryers use heated air. Customs classification follows this functional difference — centrifugal extractors fall under the centrifuge-type dryer heading, whereas heat-based dryers are classified elsewhere in the tariff schedule.

Centrifugal clothes dryers are industrial or commercial machinery and are not subject to mandatory FDA or USDA admissibility review. However, commercial buyers typically require compliance with UL or equivalent electrical safety standards, and importers should confirm that units meet OSHA-relevant machine guarding requirements for the intended workplace environment.
