9019.20.00.00 - Ozone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus; parts and accessories thereof

This HTS category, 9019.20.00.00, encompasses apparatus specifically designed for therapeutic respiration and related treatments involving gases. It includes devices for ozone therapy, which utilizes ozone gas for medical purposes; oxygen therapy, which administers supplemental oxygen; and aerosol therapy, which delivers medication or moisture in a fine mist. Artificial respiration and other therapeutic respiration apparatus, such as ventilators and positive airway pressure (PAP) devices, are also classified here, along with their essential parts and accessories. The primary function of these goods is to support or restore breathing, or to deliver inhaled therapies.

This classification is distinct from its sibling category, 9019.10, which covers mechanical therapy appliances, massage apparatus, and psychological aptitude-testing devices. While both fall under the broader heading of therapeutic appliances, 9019.10 focuses on physical manipulation, massage, or psychological assessment, whereas 9019.20.00.00 is exclusively concerned with the administration of gaseous therapies and respiratory support.

As a leaf node, 9019.20.00.00 does not have further subcategories within the HTS. Therefore, classification within this code relies on correctly identifying the apparatus as fitting the description of ozone therapy, oxygen therapy, aerosol therapy, or artificial/therapeutic respiration, along with its intended use and functional characteristics, and ensuring it is not classifiable under the preceding sibling heading. Examples include oxygen concentrators, nebulizers, CPAP machines, and ventilators, as well as their specific replacement parts like filters, tubing, or masks when imported as separate items.
