9018.90.50.40 - Sphygmomanometers and parts and accessories thereof

This category encompasses sphygmomanometers, tensimeters, and oscillometers, along with their essential parts and accessories. Sphygmomanometers are specifically designed to measure blood pressure, often utilizing an inflatable cuff and a method of detecting arterial pulse. Tensimeters and oscillometers also fall within this classification as they serve a similar diagnostic purpose of measuring blood pressure, potentially employing different measurement principles or displaying the readings in a distinct format. This includes both manual and automated devices used for this critical medical function.

At this level, the distinction between subcategories is crucial. While this specific code, 9018.90.50.40, is dedicated to sphygmomanometers and their components, the sibling category, 9018.90.50.80, is designated for "Other" instruments and appliances not otherwise specified within this broader grouping. Therefore, if an item is a blood pressure measuring device, it will be classified here; if it is a different type of medical instrument or apparatus under this broader heading, it would likely fall into the "Other" sibling.

As this node is a leaf node, there are no further subcategories to introduce. Classification within 9018.90.50.40 is definitive for items that are sphygmomanometers, tensimeters, oscillometers, or their associated parts and accessories, which are integral to the function of these blood pressure monitoring devices. When classifying parts and accessories, their primary use and essential nature in the operation of the main device are paramount considerations.
