9022.21.00.00 - For medical, surgical, dental or veterinary uses

This HTS category, 9022.21.00.00, specifically encompasses apparatus utilizing alpha, beta, gamma, or other ionizing radiations that are *exclusively designed for medical, surgical, dental, or veterinary applications*. This includes, but is not limited to, equipment used for diagnostic radiography, radiotherapy machines, and related devices intended for the treatment or examination of patients in a healthcare setting. The defining characteristic for classification under this code is the intended use in a medical or veterinary context.

Distinguishing this category from its sibling, 9022.29, is crucial. While both fall under the broader heading of apparatus using ionizing radiation, 9022.29 covers similar apparatus but designated for *other uses* that are not medical, surgical, dental, or veterinary. Therefore, if an apparatus with ionizing radiation capabilities is intended for industrial inspection, security screening, or research not directly tied to patient care, it would fall under the "other uses" classification.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 9022.21.00.00 is definitive for devices that meet the description and whose primary function is for the aforementioned healthcare purposes. Exporters and importers should carefully review the intended application and design of the apparatus to ensure accurate classification, referencing any specific technical documentation or regulatory approvals that confirm its medical or veterinary use.
