9021.10.00.90 - Other

This HTS category, 9021.10.00.90, covers "Other" orthopedic or fracture appliances, as well as parts and accessories thereof. It serves as a residual category for items within the broader classification of orthopedic or fracture appliances that are not specifically enumerated elsewhere within the 9021.10.00 subheading. This includes a wide array of devices designed to support, immobilize, or correct skeletal or muscular defects or injuries. Examples may include external fixation devices not fitting the specific descriptions of other subheadings, specialized supports, therapeutic braces, or components for these items.

Distinguishing this category from its sibling, 9021.10.00.50 (Bone plates, screws and nails, and other internal fixation devices or appliances), is crucial. The sibling category is specifically for internal implants used to fix fractures, such as plates, screws, and nails inserted directly into the bone. This "Other" category, conversely, is for external or less specifically defined orthopedic and fracture appliances that do not fall under the internal fixation description. The key differentiator lies in whether the device is primarily intended for internal bone fixation or for external support, immobilization, or therapeutic application.

As a leaf node, there are no further subcategories beneath 9021.10.00.90. Therefore, classification within this heading relies on the careful consideration of whether an item is an orthopedic or fracture appliance and whether it is not specifically provided for in any other distinct subheading under 9021.10.00. Importers must ensure that the goods in question are genuinely intended to compensate for a defect or disability of the musculoskeletal system and are not covered by more specific classifications within Chapter 90 or other relevant sections of the HTS.
