9018.20.00 - Ultraviolet or infrared ray apparatus, and parts and accessories thereof

This HTS category, 9018.20.00, specifically covers apparatus that utilize ultraviolet (UV) or infrared (IR) rays for medical, surgical, or therapeutic purposes. This includes devices designed for diagnostic imaging, treatment of skin conditions, pain relief, or other medical applications where UV or IR radiation is the primary functional element. Importantly, this classification extends to essential parts and accessories integral to the operation of these specialized ray apparatus.

Distinguishing this category from its siblings at the 9018 level is crucial. While other categories within 9018 address electro-diagnostic equipment (9018.10), syringes and cannulae (9018.30), dental instruments (9018.41), and ophthalmic appliances (9018.50), this specific heading is solely focused on the application of UV and IR radiation. It is important to note that general purpose lamps or heating elements that emit UV or IR radiation but are not designed for specific medical or surgical applications would not fall under this heading.

The subcategories within 9018.20.00 provide further refinement based on the intended use of the apparatus. The "Therapeutic" (9018.20.00.40) designation applies to devices primarily intended for treating a medical condition. The "Other" (9018.20.00.80) subheading encompasses any UV or IR ray apparatus that does not fit the therapeutic description, such as those used for purely diagnostic imaging or other specialized medical functions not explicitly defined as therapeutic.
