8540.91.20.00 - Deflection coils

This HTS category, 8540.91.20.00, specifically covers deflection coils. Deflection coils are essential components found within cathode-ray tubes (CRTs), responsible for generating magnetic fields that precisely steer the electron beam across the screen. This ensures the accurate formation of images. These coils are typically comprised of wound wire, often copper, designed to produce specific magnetic fields based on the electrical signals they receive.

Distinguishing this category from its siblings, 8540.91.15.00 (Front panel assemblies) and 8540.91.50.00 (Other), is crucial. Front panel assemblies are distinct parts that house user interface elements and sometimes display surfaces, whereas deflection coils are internal, specialized magnetic field generators. The "Other" category serves as a residual for parts of cathode-ray tubes that do not fit into more specific enumerations. Therefore, this classification is reserved solely for the deflection coils themselves, based on their function and physical construction as magnetic steering components.

As this is a leaf node, there are no further subcategories. Classification at this level depends on the definitive identification of the component as a deflection coil, which is a specialized part of a cathode-ray tube designed for controlling the electron beam's trajectory.
