Importers of Parts for Telephones & Other Voice/Data Transmission Apparatus paid $19.1M in duties in July 2026 — an effective duty rate of 12% on $162.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Parts for Telephones & Other Voice/Data Transmission Apparatus imports of $221.7M in July 2026 ran 19% above the year-to-date monthly average of $186.8M.
Last updated: July 2026 dataReplacement and OEM parts for telephone sets and other voice, image, and data transmission apparatus — circuit boards, housings, keypads, and similar components — are consolidated under a single US tariff line (8517790000). Vietnam leads supply, followed by Mexico and China, reflecting the geographic spread of electronics component manufacturing. Parts classification under this heading requires demonstrating that the component is solely or principally used with apparatus of heading 8517; parts that serve multiple equipment types may instead fall under the general parts provisions of Chapter 85.

CBP applies the 'solely or principally used' test: a component classifies as a part of heading 8517 apparatus if it has no commercially significant use other than in such apparatus. Generic electronic components (capacitors, connectors) that serve many equipment types typically classify under their own headings. Importers should document the component's design specifications and intended application to support a parts classification.
PCBAs are a frequent classification dispute area. If a PCBA constitutes a functional unit in its own right — for example, a complete modem or router board — CBP may classify it as the finished apparatus rather than as a part. Conversely, a bare board designed exclusively for a specific telephone model is more defensibly a part. A binding ruling is advisable for high-volume PCBA imports to lock in the classification.
