Overview

This HTS category, 9018.90.40.00, specifically covers percussion hammers and stethoscopes, along with their associated parts and accessories. Percussion hammers are diagnostic tools used by medical professionals to tap on the body, typically to assess underlying structures by the resulting sound. Stethoscopes are acoustic medical devices used for listening to internal body sounds, such as heartbeats, lung and bowel sounds. This classification is intended for the instruments themselves and their dedicated components.

It is important to distinguish this category from its siblings. While 9018.90.30.00 covers anesthetic instruments, and 9018.90.50 includes sphygmomanometers, tensimeters, and oscillometers, this subheading focuses exclusively on the percussion hammer and stethoscope. The broader category of electro-medical instruments, also at the same level, is separate and applies to devices powered by electricity for medical purposes, which is not the primary function of percussion hammers or stethoscopes.

As this is a leaf node, there are no further subcategories within 9018.90.40.00. Therefore, classification into this specific HTS code relies on the clear identification of the imported or exported good as either a percussion hammer, a stethoscope, or a part or accessory specifically designed for these instruments. Classification decisions should be guided by the intended use and functional design of the item in question, aligning with the general scope of Chapter 90 for medical instruments.
