9018.20.00.40 - Therapeutic

This HTS category, 9018.20.00.40, specifically covers "Therapeutic" ultraviolet or infrared ray apparatus. These are instruments designed for the treatment of medical conditions using electromagnetic radiation within the ultraviolet or infrared spectrum. Examples include devices used for phototherapy to treat skin conditions like psoriasis or eczema, pain relief through infrared heat therapy, or germicidal lamps used for sterilization in a therapeutic context. The core function of these devices is to actively promote healing or alleviate symptoms through the application of these specific wavelengths of light.

This category is distinct from its sibling, 9018.20.00.80, which is designated for "Other" ultraviolet or infrared ray apparatus. While both fall under the broader heading of therapeutic or diagnostic instruments, the "Other" category would encompass devices that might use UV or IR rays for purposes other than direct therapeutic application, such as diagnostic imaging or non-medical sterilization, provided they are not classified elsewhere. The crucial differentiator for 9018.20.00.40 is the explicit intended use for medical treatment.

As this is a leaf node in the HTS classification system, there are no further subcategories to detail. Classification under 9018.20.00.40 is final for therapeutic ultraviolet or infrared ray apparatus. Importers should carefully consider the primary intended function of the apparatus, ensuring it is specifically designed and marketed for therapeutic purposes to correctly assign it to this classification.
