8533.10.00 - Fixed carbon resistors, composition or film types

This HTS category, 8533.10.00, specifically addresses fixed carbon resistors. These components are characterized by their fixed resistance value, meaning they do not offer adjustable resistance. They are typically constructed using carbon composition or carbon film elements, which form the resistive material. These resistors are essential for controlling electrical current flow in a wide array of electronic circuits and devices.

It is important to distinguish this category from its siblings. Unlike wirewound variable resistors (8533.21 and 8533.29) or other variable resistors (8533.40), the resistors classified here have a non-adjustable resistance. Furthermore, this category is distinct from "Other fixed resistors" which would encompass fixed resistors not made from carbon composition or film materials. Similarly, it is separate from "Parts" (8533.90) which are components for resistors rather than complete resistor units.

Within this classification, further subdivisions exist to refine the classification of fixed carbon resistors. These subcategories help differentiate between resistors designed for specific mounting methods, such as surface mounting by contact, and those with different configurations, like resistor networks that contain multiple resistors within a single package and have more than two leads. These distinctions are crucial for accurate inventory management and compliance with specific trade regulations.
