9027.30.40 - Electrical

This HTS category, 9027.30.40, specifically covers electrical spectrometers, spectrophotometers, and spectrographs that utilize optical radiations such as ultraviolet, visible, and infrared light. These instruments are designed for the analysis of physical or chemical properties of substances by measuring their interaction with these light spectrums. Examples include devices used for quantitative and qualitative analysis, identifying components, and determining concentration levels in various samples.

This classification is distinguished from its sibling category, 9027.30.80 ("Other"), by its specific focus on instruments employing optical radiation for spectral analysis. While the "Other" category would encompass related analytical instruments that do not fit the precise definition of spectrometers, spectrophotometers, or spectrographs using optical radiations, or perhaps those employing different analytical principles not covered by the parent heading.

Within this node, further subcategories exist to refine classification based on specific instrument types. 9027.30.40.40 designates "Spectrophotometers," which are a type of spectrometer that measures the intensity of light as a function of wavelength, often used for quantitative analysis. The subcategory 9027.30.40.80, "Other," accounts for any remaining electrical spectrometers and spectrographs that do not specifically fall under the spectrophotometer designation but still meet the criteria of using optical radiations for analysis.
