HS v2022 Code: 853340

About electrical resistors; variable, including rheostats and potentiometers (excluding heating)

HS code 853340 covers a crucial component in the electrical and electronics industry - variable electrical resistors. These devices, including rheostats and potentiometers, play a vital role in regulating and controlling the flow of electrical current, making them indispensable in a wide range of applications, from consumer electronics to industrial automation. As a key part of the broader electrical and electronics sector, this industry contributes significantly to the global economy, enabling the development and functioning of countless electronic devices and systems.

Production process

The production of variable electrical resistors typically involves a multi-step process. First, the resistive element, often made of carbon, metal, or a combination of materials, is precisely engineered to achieve the desired resistance characteristics. This element is then integrated into a housing, which may include a rotary or sliding mechanism to allow for adjustments in resistance. The assembly is then tested and calibrated to ensure consistent performance and compliance with industry standards.

Production inputs

The main inputs required for the production of variable electrical resistors include the raw materials for the resistive element, such as carbon, metal alloys, or specialized compounds. Additionally, the manufacturing process requires various mechanical components, such as housings, shafts, and knobs, as well as precision tools and equipment for assembly and testing. Depending on the specific application, additional inputs may include specialized coatings or enclosures to protect the resistor from environmental factors.

Production outputs

The primary output of HS code 853340 is variable electrical resistors, which are then consumed by a wide range of industries and applications. These resistors are essential components in 851762 Automatic regulating or controlling instruments and apparatus and 853710 Boards, panels, consoles, desks, cabinets and other bases for the goods of heading 8537, not equipped with their apparatus, as well as in consumer electronics, industrial automation, and various other electrical and electronic systems.
