9027.50.80.15 - Chemical analysis instruments and apparatus

This HTS category encompasses a broad range of instruments and apparatus designed for chemical analysis that utilize optical radiations, specifically ultraviolet, visible, or infrared light. These devices are employed to identify, quantify, or study the chemical composition and properties of substances through the interaction of light with the sample. Examples include spectrophotometers, fluorimeters, and certain types of chromatographs that employ optical detection methods.

Distinguishing this subcategory from its siblings, 9027.50.80.20, which specifically covers thermal analysis instruments, is crucial. While thermal analysis might involve optical measurements in some applications, this section focuses on instruments where optical radiation is the primary means of analysis. Similarly, 9027.50.80.60, "Other," is reserved for instruments not fitting the specific optical analysis criteria or other defined subcategories.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification within 9027.50.80.15 relies on a thorough understanding of the instrument's primary function in performing chemical analysis through the application of ultraviolet, visible, or infrared radiation. The presence and use of specific optical components and the analytical methodology employed are key determining factors.
