Products classified under Tariff item 9021.31.00
Ankle Fusion Implant Plate
Ankle fusion implant plate system designed for ankle arthrodesis, featuring an artificial joint surface replacement and bone fixation screws to fuse the tibiotalar joint in severe arthritis cases. The titanium construct is surgically implanted to replace the damaged joint surface and provide stability. This product is classified as an artificial joint under tariff item 9021.31.00 as it replaces the function of the natural ankle joint.
Ceramic Knee Implant Femoral Component
Ceramic knee implant femoral component, part of a total knee replacement system, made from zirconia ceramic and articulating with tibial and patellar components to mimic natural knee motion. Engineered for high wear resistance in orthopaedic surgery, this component replaces the natural femoral condyles. It is an artificial joint component under tariff item 9021.31.00.
CoCrMo Shoulder Joint Ball Head
CoCrMo shoulder joint ball head, a cobalt-chromium-molybdenum alloy humeral head component for reverse or total shoulder arthroplasty, replacing the natural ball in rotator cuff deficient patients. Precision-machined for glenoid articulation, this implant restores shoulder joint function. It is classified as an artificial joint under tariff item 9021.31.00.
Elbow Hinge Prosthesis
Elbow hinge prosthesis, a linked hinge mechanism replacing the elbow joint in total elbow arthroplasty for rheumatoid arthritis or trauma patients, with cemented or press-fit stems. It provides flexion-extension motion and is surgically implanted to restore joint function. This product is an artificial joint under tariff item 9021.31.00.
Metatarsophalangeal Joint Implant
Metatarsophalangeal joint implant, a silicone or metal toe joint replacement for hallux rigidus or rheumatoid arthritis, restoring great toe motion with hinged or hemi-resurfacing designs. Implanted in foot surgery, this device replaces the damaged joint to alleviate pain and improve mobility. It is classified as an artificial joint under tariff item 9021.31.00.
Polyethylene Acetabular Liner
Polyethylene acetabular liner, an ultra-high molecular weight polyethylene (UHMWPE) insert that lines the metal acetabular shell in hip replacements, providing a low-friction bearing surface against the femoral head. Vitamin E stabilized for reduced wear, this liner is a critical component of an artificial hip joint. It is classified under tariff item 9021.31.00 as part of an artificial joint.
Spinal Disc Arthroplasty Device
Spinal disc arthroplasty device, an artificial intervertebral disc prosthesis preserving motion segment between lumbar vertebrae, with cobalt-chrome endplates and ultra-high polyethylene core. Designed for degenerative disc disease treatment, this device replaces the natural disc to maintain spinal mobility. It is an artificial joint under tariff item 9021.31.00.
Tibial Tray for Total Knee Replacement
Tibial tray for total knee replacement, a metallic platform component that anchors the polyethylene tibial insert in total knee arthroplasty systems, available in cemented and cementless designs for bone integration. Customizable for patient anatomy, this tray is part of an artificial knee joint. It is classified under tariff item 9021.31.00 as a component of an artificial joint.
Titanium Hip Replacement Prosthesis
Titanium hip replacement prosthesis, a complete artificial hip joint made primarily from titanium alloys, designed for surgical implantation to replace damaged hip joints in patients with arthritis or fractures. It includes a femoral stem, acetabular cup, and articulating components. This product is an artificial joint under tariff item 9021.31.00.
Wrist Arthroplasty Radial Component
Wrist arthroplasty radial component, a radial carpal component for total wrist replacement systems, featuring ball-and-socket articulation to preserve hand function in rheumatoid or osteoarthritis patients. Cobalt-chrome construction, this component is part of an artificial wrist joint. It is classified under tariff item 9021.31.00 as a component of an artificial joint.
