HS Code 90.21 – Orthopaedic appliances; including crutches, surgical belts and trusses; splints and other fracture appliances; artificial parts of the body; hearing aids and other which are worn, carried or implanted in the body to compensate for a defect or disability

HS code 9021 is a 4-digit heading in the Harmonized System that covers: Orthopaedic appliances; including crutches, surgical belts and trusses; splints and other fracture appliances; artificial parts of the body; hearing aids and other which are worn, carried or implanted in the body to compensate for a defect or disability. Heading 9021 encompasses a vital range of orthopaedic appliances, artificial body parts, and other devices designed to compensate for a defect or disability. This broad classification includes external aids like crutches, surgical belts, trusses, splints, and fracture appliances, all aimed at supporting, correcting, or assisting a body part. Crucially, it also covers artificial parts of the body, such as prosthetic limbs, artificial joints (e.g., hip or knee implants), and internal devices like pacemakers and cochlear implants. Hearing aids, another significant category, are also included, providing essential assistance for auditory defects. The unifying characteristic is that these items are worn, carried, or implanted in the body to compensate for a defect or disability, thereby improving functionality and quality of life. This heading is of immense global trade significance, driven by an aging global population, increasing healthcare access, and advancements in medical technology. Accurate classification under 9021 is crucial for customs compliance, duty assessment (often zero or reduced for essential medical devices), and navigating specific regulatory approvals (e.g., medical device registrations) that are paramount for market entry. As part of Section XVIII, it represents the pinnacle of precision and bio-integration in medical instruments, directly interfacing with the human or animal body.

Crutches, walking frames, walkers, manual wheelchairs, motorized wheelchairs, prosthetic limbs (arm, leg), artificial hip joints, artificial knee joints, hearing aids, cochlear implants, pacemakers, surgical belts, hernia trusses, neck braces, back braces, orthotic insoles, custom-molded orthoses, medical compression stockings, fracture splints, intraocular lenses, dental implants, ostomy appliances, external breast prostheses, spinal fixation devices, bone plates and screws.

Common misclassification issues for 9021 arise when distinguishing these specialized medical devices from general medical supplies or non-medical items. For instance, a general elastic bandage (3005) might be confused with a medical compression stocking (9021), but the latter is specifically designed to compensate for a defect like venous insufficiency. Another error is classifying general sports protection equipment (9506), such as an athletic knee brace, instead of a medical knee brace prescribed for an injury or condition (9021). Similarly, specialized medical furniture like examination tables (9402) that do not incorporate or act as an orthopaedic appliance itself, should not be classified here. The key is the explicit purpose of compensating for a defect or disability.

In 2025, the top exporters of HS code 9021 in UN Comtrade data were the United States ($13.6B, 16% of world exports), the Netherlands ($11.4B) and Germany ($8.0B). World exports came to about $87.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 9021 in UN Comtrade data were the United States ($19.4B, 22% of world imports), the Netherlands ($8.7B) and Germany ($6.7B). World imports came to about $88.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 9021 is a 4-digit heading under Chapter 90 of the Harmonized System. The first 2 digits (90) identify the chapter, and digits 3-4 (21) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
