U.S. exports of parts for microphones, loudspeakers, headphones, earphones & audio amplifiers (HS 851890) totaled $32.8M in July 2026.
Importers of Parts for Microphones, Loudspeakers, Headphones, Earphones & Audio Amplifiers paid $2.3M in duties in July 2026 — an effective duty rate of 20% on $11.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataChina dominates US imports of parts for microphones, loudspeakers, headphones, earphones, and audio amplifiers — and goods of Chinese origin in this heading are subject to Section 301 tariffs, a significant cost driver for OEMs and repair-parts importers alike. The heading carries six distinct 10-digit tariff lines, including telephone handset and repeater parts (8518901000), printed circuit assemblies for line telephone and repeater equipment (8518902000), and general microphone, loudspeaker, and amplifier parts (8518903000 and 8518908100), among others. Correct line selection depends on both the specific parent article the part serves and whether it constitutes a printed circuit assembly, making classification here more granular than for finished goods. Mexico and Taiwan are secondary suppliers, with Taiwan particularly relevant for precision acoustic components and PCB assemblies.

The US tariff schedule under this heading separates printed circuit assemblies for line telephone and repeater equipment (8518902000 and 8518906000) from general microphone, loudspeaker, and amplifier parts. A PCB assembly designed for a consumer headphone or audio amplifier would fall under the general parts lines (8518903000 or 8518908100), not the telephony-specific PCB lines. The end-use design of the assembly — not just its physical form — drives the correct classification.
Customs typically looks for evidence that the article is incomplete or unfinished for its own use — for example, a raw driver unit without an enclosure, or a crossover network without a cabinet. Technical datasheets showing the article's role as a subcomponent, purchase orders referencing it as a spare or production part, and the absence of retail packaging all support a parts classification. When the article could plausibly function on its own, a binding ruling request from CBP is advisable.
