HS v2022 Code: 851840

About amplifiers; audio-frequency electric

HS code 851840 covers the import and export of audio-frequency electric amplifiers, which are essential components in a wide range of electronic devices and systems. These amplifiers play a crucial role in boosting and enhancing audio signals, enabling the clear and powerful reproduction of sound in applications such as music equipment, public address systems, and telecommunications. As a key part of the broader electronics and electrical equipment industry, the trade of audio-frequency electric amplifiers is an important contributor to the global economy.

Production process

The production of audio-frequency electric amplifiers typically involves several key steps. First, the core electronic components, such as transistors, resistors, and capacitors, are assembled onto a printed circuit board. The amplifier circuits are then designed and integrated onto the board, often using specialized integrated circuits. The housing or casing is then manufactured and the internal components are carefully installed. Finally, the amplifiers undergo rigorous testing and quality control checks before being packaged and prepared for distribution.

Production inputs

The main inputs required for the production of audio-frequency electric amplifiers include electronic components like transistors, resistors, and capacitors, as well as specialized integrated circuits and other semiconductors. Additionally, the manufacturing process requires various raw materials such as metals, plastics, and other materials for the housing and casing. Specialized machinery and equipment, such as circuit board assembly tools and testing equipment, are also essential inputs for this industry.

Production outputs

The primary output of HS code 851840 is audio-frequency electric amplifiers, which are then consumed by a wide range of other industries and applications. These amplifiers are commonly used in 851810 Sound recording or reproducing apparatus, 852872 Reception apparatus for television, and 851760 Transmission apparatus for radio-telephony, radio-telegraphy, radio-broadcasting or television, among others. The amplifiers help to power and enhance the audio capabilities of these various electronic devices and systems.
