U.S. imports of machines and mechanical appliances with individual functions, nesoi (HS 847989) totaled $672.1M in August 2026, imported from 87 countries.
Importers of Machines and Mechanical Appliances with Individual Functions, NESOI paid $77.3M in duties in August 2026, an effective tariff rate of 11.50% of the $672.1M imported — duty actually collected as a share of that value, not the published tariff schedule. Machines and Mechanical Appliances with Individual Functions, NESOI imports of $672.1M in August 2026 ran 16% above the year-to-date monthly average of $581.8M.
Last updated: August 2026 dataHeading 847989 functions as the catch-all for mechanical appliances with individual functions not more specifically classified elsewhere in Chapter 84, encompassing a remarkably diverse range of equipment — from hydraulic accumulators and ultrasonic cleaning devices to oil-field wireline tools, industrial vibrators, and automated printed-circuit-board component placement machines. Germany leads US import supply, followed by Canada and Mexico, reflecting both precision-engineering exports and North American supply-chain integration. Because this heading is a residual, CBP scrutinizes classification carefully; importers should document why no more specific heading applies before defaulting to 847989. Several lines — including oil and gas field wireline equipment (8479899550/8479899850) and PCB placement machines (8479899200) — carry distinct duty treatment that rewards precise product identification.

CBP can reclassify goods out of the NESOI heading if a more specific provision exists elsewhere in Chapter 84 or in another chapter. This can result in additional duties, penalties, or delays. Importers should conduct a thorough classification analysis — including review of chapter notes and Explanatory Notes — and consider a binding ruling request for novel or complex machinery before relying on 847989 as a catch-all.
The US schedule under 847989 includes dedicated lines for oil and gas field wireline and downhole equipment (8479899550 and 8479899850), reflecting the commercial significance of this equipment category. Importers of such tools should ensure their entry documents clearly identify the equipment as wireline or downhole tools, as the residual NESOI lines carry different duty rates and the distinction matters for accurate duty calculation.
