8533.10.00.65 - Carbon film

This category, HTS 8533.10.00.65, specifically covers carbon film fixed electrical resistors. These resistors are characterized by a resistive layer of carbon deposited onto an insulating substrate, typically in a film form. They are utilized to control electrical current flow in various electronic circuits, offering specific resistance values as designed.

Distinguishing this category from its sibling, 8533.10.00.60 (Carbon composition resistors), is the method of creating the resistive element. While both utilize carbon, composition resistors employ a mixture of carbon particles and a binder, whereas carbon film resistors rely on a precisely applied thin film of carbon. This difference in construction influences their electrical properties, tolerance, and applications.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification within this code is dependent on the precise identification of the product as a fixed carbon film resistor, manufactured by depositing a carbon film onto a substrate, and not as a carbon composition type. This ensures accurate differentiation from other fixed resistor types under heading 8533.
