Overview
This HTS category specifically covers spectrophotometers that operate by utilizing optical radiations, including ultraviolet (UV), visible, and infrared (IR) light. These instruments are designed to measure the absorption, transmission, or reflection of light by a sample across a spectrum of wavelengths. They are essential tools in various scientific and industrial fields for identifying substances, determining their concentration, and studying their chemical and physical properties. Examples include UV-Vis spectrophotometers used in chemistry and biology, and IR spectrophotometers employed in materials analysis and quality control.
Within the broader classification of spectrometers, spectrophotometers, and spectrographs (9027.30), this subcategory distinguishes itself from its sibling, "Other" (9027.30.40.80), by focusing on instruments that are electrically operated and employ optical radiation detection principles. The distinction lies in the underlying technology and the specific method of spectral analysis employed.
As this is a leaf node within the HTS, there are no further subcategories. Classification at this level signifies that the goods are definitively identified as electrical spectrophotometers utilizing optical radiations, and no further breakdown is required for customs purposes. Classification decisions at this point would focus on confirming the instrument's operational principles and confirming it is not specifically excluded by other headings or notes within Chapter 90.
