9018.90.50 - Sphygmomanometers, tensimeters and oscillometers; all the foregoing and parts and accessories thereof

This HTS category encompasses sphygmomanometers, tensimeters, and oscillometers, along with their associated parts and accessories. These instruments are designed for measuring blood pressure and related cardiovascular indicators. Sphygmomanometers, in particular, are devices used to gauge the pressure of blood in the arteries. Tensimeters and oscillometers serve similar diagnostic purposes in assessing circulatory function. The inclusion of parts and accessories ensures that components integral to the functioning of these primary instruments are also classified under this heading.

Distinguishing this category from its siblings, it is important to note that while sibling categories like 9018.90.40.00 cover percussion hammers and stethoscopes, and others focus on anesthetic or electro-medical equipment, this specific heading is dedicated to devices that directly measure and monitor blood pressure and circulatory dynamics. It is distinct from general diagnostic instruments or purely electrical medical devices, focusing specifically on the mechanics and principles of blood pressure measurement.

This category is further subdivided to provide more granular classification. The subcategory 9018.90.50.40 specifically covers sphygmomanometers and their parts and accessories, offering a more precise classification for these widely used devices. The residual subcategory, 9018.90.50.80, accounts for other related tensimeters and oscillometers not otherwise specified, ensuring comprehensive coverage within this blood pressure measurement domain.
