HS Code 85.18 – Microphones and their stands; loudspeakers, mounted or not in their enclosures; headphones and earphones, combined or not with a microphone, and sets of a microphone and one or more loudspeakers; audio-frequency and electric sound amplifiers and sets

HS code 8518 is a 4-digit heading in the Harmonized System that covers: Microphones and their stands; loudspeakers, mounted or not in their enclosures; headphones and earphones, combined or not with a microphone, and sets of a microphone and one or more loudspeakers; audio-frequency and electric sound amplifiers and sets. HS Code 8518 encompasses a broad range of essential audio components critical to entertainment, professional sound, and communication industries. This heading specifically covers microphones (and their stands), loudspeakers (whether or not mounted in their enclosures), headphones and earphones (which may or may not include a microphone), and sets combining a microphone with one or more loudspeakers. Additionally, it includes audio-frequency electric sound amplifiers and complete amplifier sets. The scope is defined by the primary function of sound input, output, or amplification. It differentiates standalone audio components from complete sound recording or reproducing systems (found in 8519 or 8521) or telecommunication apparatus (8517) where these components are integrated but not the primary function. For instance, a professional studio microphone is classified here, but a smartphone incorporating a microphone is not. The classification is vital for determining correct duties, ensuring compliance with safety standards (e.g., CE marking), and tracking trade flows in the global audio electronics market. Historically, this heading has evolved from covering basic analog equipment to sophisticated digital and wireless audio devices, reflecting advancements in sound technology. As part of Section XVI, which covers machinery and electrical equipment, it highlights the electromechanical nature of these devices, emphasizing their role as core building blocks in larger electronic systems.

Studio condenser microphones, dynamic vocal microphones, wireless lavalier microphone systems, microphone stands, noise-canceling headphones, in-ear monitors (earphones), Bluetooth portable loudspeakers, professional PA system loudspeakers, car audio component speakers, soundbars (without video capabilities), home theater amplifiers, guitar amplifiers, audio mixers with integrated amplifiers, gaming headsets with microphones, conference call speakerphones, public address system amplifiers, desktop computer speakers, smart speakers (without display), bone conduction headphones, intercom system handsets, sound reinforcement system subwoofers, active studio monitors, passive loudspeakers, headphone amplifiers, USB microphones.

Common misclassifications under HS 8518 often occur when distinguishing standalone components from integrated systems or other electronic apparatus. Traders might mistakenly classify a complete sound recording system (like a digital audio recorder) here, which belongs to 8519. Another frequent error is classifying telecommunication apparatus, such as smartphones or video conferencing units where microphones/loudspeakers are integrated, under 8518; these typically fall under 8517 (telephones) or 8525 (transmission apparatus). Parts and accessories specifically designed for the apparatus of 8519 or 8521, such as a specialized circuit board for a CD player, should go to 8522, not 8518. The key is to assess the primary function and the standalone nature of the product.

In 2025, the top exporters of HS code 8518 in UN Comtrade data were China ($16.4B, 29% of world exports), Vietnam (about $11.0B) and Germany ($3.6B). World exports came to about $56.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 8518 in UN Comtrade data were the United States ($12.2B, 21% of world imports), Germany ($4.3B) and Japan ($2.4B). World imports came to about $58.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 8518 is a 4-digit heading under Chapter 85 of the Harmonized System. The first 2 digits (85) identify the chapter, and digits 3-4 (18) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
