The item concerned is a part for the Lightspeed Aviation’s Zulu 3 aviation headset. It is referred to as a Boom assembly (without a microphone), SKU number is 280-00001-000.A2. One end of this boom assembly connects to the earcup of the headset, both mechanically and electronically. The opposite end will incorporate the microphone. The boom assembly extends from the earcup of the headset and positions the microphone so that it is in close proximity to the user’s mouth. The booms are flexible/adjustable, so the user can position the microphone as needed. The Boom assembly is covered in black Polyolefin material. The interior of the boom is made from flexible Uniprise tubing. Uniprise gooseneck tubing is a flexible metal tube that can bend and hold its shape. It is designed to be adjustable, durable, and precise, making it ideal for applications where positioning matters such as headset microphones. The assembly also includes the microphone wire which facilitates an audio/electrical connection between the microphone and the cup of the headset. The applicable subheading for the item concerned, Boom assembly (without a microphone), SKU number is 280-00001-000.A2, will be 8518.90.8100, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Microphones and stands therefor; loudspeakers, whether or not mounted in their enclosures; headphones and earphones, whether or not combined with a microphone, and sets consisting of a microphone and one or more loudspeakers; audio-frequency electric amplifiers; electric sound amplifier sets; parts thereof: Parts: Other: Other”.
