N353460 · 2025-09-24 — The tariff classification of a Pre-Amp PCBA from China
The item concerned is a Pre-Amp, printed circuit board assembly (PCBA), part number 200-00011-000.A2. This PCBA is used within a noise canceling aviation headset. The PCBA will be incorporated within the boom assembly (microphone assembly) of the Sierra Aviation headset (model# HCC-90). This PCBA holds the electronic components that process the analog signal generated by the microphone. The primary function of a pre-amp (pre-amplifier) is to amplify low-level audio signals (i.e. from a microphone), prior to further amplification. The applicable subheading for the Pre-Amp, printed circuit…
N321626 · 2021-10-01 — The tariff classification of audio-frequency electric amplifiers from China
The items concerned are referred to as the VYPYR X series of audio-frequency electric amplifiers, model numbers - VYPYR X1, VYPYR X2, and VYPYR X3. These audio-frequency electric amplifiers are for use with various musical instruments (i.e., electric, acoustic, and bass guitars). Each model of amplifier is a combination of preamp with digital effects, power amplifier, and speaker enclosed in a wooden cabinet. The VYPYR X2 and X3 can be remotely controlled via their on-board Bluetooth controller and a control application for iOS devices. They can also stream audio, essentially turning them…
N268186 · 2015-09-17 — The tariff classification of a sound system from an unspecified country of origin
The item concerned is referred to as the “HyperSound Clear 500P System.” This device is an audio sound system comprised primarily of an amplifier and two speakers. The HyperSound System is used to amplify audio frequency input and project sound waves along a narrow ultrasonic beam of energy. This method of amplification and sound projection creates a highly directional and intelligible sound over a greater distance than traditional sound systems. Unlike traditional audio speakers which radiate audible sound in all directions, the HyperSound System uses software to electronically mix audible…
N265335 · 2015-06-19 — The tariff classification of an AM/FM glass antenna amplifier from South Korea
The merchandise that is the subject of this ruling request is an AM/FM glass antenna amplifier, identified as AMP ASSY-G/ANT, item code 96270-3X000. The main components of the antenna amplifier are an input power supply terminal, a signal output connector, and a PCB assembly with wire assembly. The antenna amplifier is connected to the heating pattern located on the rear window of an automobile, and functions by sensing an electromagnetic wave (or radio frequency wave) signal received by the heating pattern and amplifying it through the antenna. The applicable subheading for the AM/FM glass…
