9021.10.00 - Orthopedic or fracture appliances, and parts and accessories thereof

This category encompasses orthopedic and fracture appliances, along with their associated parts and accessories. These are devices designed to support, immobilize, or correct deformities of the body's skeletal structure, aiding in the healing process after injury or surgery. Examples include external fixation devices, casts, braces, splints, crutches, surgical belts, and trusses, all intended to provide structural support or alignment.

Distinguished from its siblings, this heading specifically addresses external orthopedic and fracture care. It does not include artificial teeth or dental fittings (9021.21), nor does it cover other general artificial body parts or hearing aids (9021.3 and 9021.4 respectively). Similarly, implantable devices like pacemakers for stimulating heart muscles (9021.50) fall under separate classifications.

Within this classification, further subdivisions exist to refine the scope. Subcategories like "Bone plates, screws and nails, and other internal fixation devices or appliances" (9021.10.00.50) capture items surgically implanted to stabilize fractures internally. The residual category, "Other" (9021.10.00.90), is for those orthopedic or fracture appliances not specifically enumerated elsewhere within this heading, ensuring all relevant items are appropriately classified.
