8518.10 - Microphones and stands therefor:

This category specifically encompasses microphones, which are electro-acoustic transducers that convert sound waves into electrical signals. It also includes stands and mounts designed to support or position microphones. The primary function of these items is sound capture for a wide range of applications, from professional audio recording and broadcasting to voice recognition and communication systems.

Unlike sibling categories such as loudspeakers (8518.2X) which reproduce sound, or headphones and earphones (8518.30) which deliver sound directly to the user, microphones are dedicated to the input of audio. Similarly, this classification is distinct from audio-frequency electric amplifiers (8518.40) and amplifier sets (8518.50), which are designed to increase the power or amplitude of electrical signals, and parts (8518.90) which are components of the aforementioned apparatus.

Within this category, further distinctions are made. The subheading 8518.10.40.00 covers specialized microphones designed for telecommunication use, characterized by specific frequency ranges, diameters, and heights. The residual category, 8518.10.80, accounts for all other microphones and their stands that do not meet the precise criteria of the more specific sub-designation, ensuring comprehensive coverage of this product group.
