U.S. imports of machines & mechanical appliances with individual functions, nesoi (HS 847989) totaled $623.3M in June 2026, traded with 83 countries.
Importers of Machines & Mechanical Appliances with Individual Functions, NESOI paid $77.5M in duties in June 2026 — an effective duty rate of 15% on $513.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Machines & Mechanical Appliances with Individual Functions, NESOI imports of $623.3M in June 2026 ran 12% above the year-to-date monthly average of $555.3M.
Germany leads US imports under this broad residual heading, which functions as the catch-all for purpose-built machines that perform a single, self-contained mechanical function but do not fit any more specific Chapter 84 provision — a classification that customs examiners scrutinize closely. The 20 active 10-digit lines span an unusually wide range of end uses: oil and gas field wireline and downhole equipment (8479899550/8479899850), automated electronic component placement machines for printed circuit board manufacturing (8479899200), hydraulic accumulators (8479899565/8479899865), ultrasonic cleaning devices, industrial vibrators, and trash compactors, among others. Canada and Mexico are also major suppliers, meaning many shipments may qualify for USMCA preferential treatment when rules-of-origin requirements are met. Importers should document the machine's specific function thoroughly, as misclassification into this NESOI provision — rather than a dedicated heading — is a common audit finding.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP expects a detailed technical description of the machine's principal function, engineering drawings or spec sheets, and evidence that no more specific heading in Chapter 84 or 85 applies. A binding ruling request is advisable for novel or high-value equipment, since the NESOI provision is frequently challenged during post-entry review.
Wireline and downhole equipment under 8479899550 or 8479899850 is purely industrial and carries no mandatory admissibility review, but exporters and re-exporters should check whether the equipment's technical parameters trigger Export Administration Regulations (EAR) controls, particularly for tools destined for certain end users or countries.
