Last updated: August 2026 dataReplacement and aftermarket parts for invalid carriages — including wheelchair frames, drive wheels, seating systems, and electronic control units for powered models — are traded under this dedicated SITC category, distinct from broader vehicle parts headings. The classification boundary between a 'part' and a 'medical accessory' can be contested at entry, particularly for cushions, postural supports, or electronic components that may also be classifiable as medical devices. Importers sourcing powered-wheelchair components should be aware that FDA device regulations may apply to certain electronic assemblies.

CBP generally classifies an article as a part if it is integral to the carriage's function and not complete in itself as a separate device. Postural supports, pressure-relief cushions, or standalone electronic controllers may be classifiable elsewhere — potentially as medical devices — so a binding ruling request or consultation with a licensed customs broker is advisable for ambiguous items.
Electronic control units that are integral to a powered wheelchair's operation may fall under FDA's medical device framework if they meet the definition of a device component. Importers should confirm whether the specific assembly requires FDA registration or clearance before shipment to avoid holds at the port of entry.
