9021.31.00.00 - Artificial joints and parts and accessories thereof

HTS Code 9021.31.00.00 specifically classifies artificial joints and their associated parts and accessories. This category encompasses a wide range of prosthetic implants designed to replace or augment damaged or missing joints within the human body. Examples include artificial hip, knee, shoulder, and ankle joints, as well as components such as acetabular cups, femoral stems, tibial components, and patellar components, all intended for surgical implantation to restore mobility and function.

This subcategory is distinguished from its sibling, 9021.39.00.00 ("Other"), which covers artificial parts of the body not elsewhere specified. While 9021.31.00.00 is narrowly focused on joint replacements, the "Other" category would encompass a broader array of artificial body parts, such as prosthetic limbs, ocular prostheses, or dental implants, provided they are not artificial joints. The defining characteristic for classification under 9021.31.00.00 is the specific function of replacing a bodily joint.

As a leaf node, 9021.31.00.00 does not have further subcategories. Therefore, the classification hinges on whether a product is designed and manufactured as an artificial joint or a direct component thereof for surgical implantation. The intent and primary use of the item are crucial for correct classification, ensuring that only products fulfilling this specific role are assigned to this HTS code.
