9018.90.75.70 - Parts and accessories of dialysis instruments and apparatus

This HTS classification, 9018.90.75.70, specifically designates parts and accessories for dialysis instruments and apparatus. This encompasses a wide range of components that are integral to the functioning of devices used in renal dialysis, such as blood tubing sets, dialyzers, filters, pumps, valves, sensors, and replacement parts for these machines. The key criterion for classification here is that the item must be specifically designed and intended for use with dialysis equipment.

This category is distinct from its sibling, 9018.90.75.20, which covers the complete dialysis instruments and apparatus themselves. While that code applies to the assembled machines, 9018.90.75.70 is for the individual components and supplementary items necessary for the operation, maintenance, and repair of these sophisticated medical devices. It does not include general laboratory equipment or unrelated medical supplies.

As this is a leaf node in the HTS structure, there are no further subdivisions under this specific code. Therefore, the focus for classification relies on clearly establishing the direct relationship and intended use of the item as a component or accessory of dialysis equipment, differentiating it from standalone medical devices or unrelated parts.
