HS Code for Power amplifier

Power amplifiers are classified under HS code 851840, which specifically covers audio-frequency electric amplifiers. This classification is part of Chapter 85, which encompasses electrical machinery and equipment. Heading 8518 includes microphones, loudspeakers, and headphones, as well as the amplifiers required to drive them. The sub-heading 8518.40 is applied because the primary function of a power amplifier is to increase the amplitude of electrical signals within the human audible frequency range, typically between 20 Hz and 20,000 Hz. These devices are essential for converting low-power electronic signals into a level sufficient to drive loudspeakers. The classification remains consistent whether the amplifier is used for professional sound reinforcement, home theater systems, or public address installations, provided the device does not include a built-in radio tuner or sound recording mechanism.

Products Included

• Stereo power amplifiers
• Mono-block audio amplifiers
• Public address (PA) system amplifiers
• Home theater power amplifiers
• Multi-channel audio amplifiers
• Rack-mounted professional power amps

Common Misclassification

Power amplifiers are often confused with HS code 8517.62, which covers machines for the reception, conversion, and transmission of voice or data, particularly in networking contexts. Another common misclassification is HS code 8527.91, which is used for radio-broadcast receivers combined with sound reproducing apparatus; if the amplifier includes a tuner, it must move to 8527. Additionally, RF (Radio Frequency) amplifiers used in telecommunications are classified under 8543.70 rather than 8518.40.

FAQ

What is the HS code for power amplifiers?

The standard HS code for audio-frequency power amplifiers is 8518.40.

Are guitar amplifiers classified under this code?

Yes, standalone guitar power amplifiers are generally classified under 8518.40, though integrated combo amps (with speakers) may sometimes be classified under 8518.21 or 8518.22 depending on the speaker configuration.
