Overview

HTS Code 9027 encompasses a broad range of sophisticated instruments and apparatus designed for scientific analysis, measurement, and checking across various physical and chemical properties. This category includes devices used to analyze the composition of gases and smoke, measure fundamental properties like viscosity and surface tension, and quantify phenomena such as heat, sound, and light. It also specifically calls out microtomes, which are precision instruments used for preparing tissue samples for microscopic examination.

Crucially, this chapter (90) is dedicated to precision instruments and apparatus, distinguishing them from more general tools. Within this chapter, HTS 9027 is set apart from categories like 9018 (Medical, surgical, dental or veterinary instruments and appliances) or 9030 (Oscilloscopes, spectrum analyzers and other instruments and apparatus for measuring or checking electrical quantities). While these might involve analysis, 9027 focuses specifically on physical and chemical analysis or the measurement of physical properties like heat, light, or sound.

The subcategories within 9027 provide further refinement based on the scientific principle or application of the instrument. For instance, 9027.10 covers gas and smoke analyzers, while 9027.30 and 9027.50 differentiate instruments based on whether they utilize optical radiations (like spectrometers) or other means for analysis. The remaining subdivisions address other analytical apparatus and the specific inclusion of microtomes and their associated parts and accessories.
