U.S. imports of mechanical appliances for projecting or spraying liquids or powders (nesoi) (HS 842489) totaled $65.7M in July 2026, traded with 53 countries.
Importers of Mechanical Appliances for Projecting or Spraying Liquids or Powders (NESOI) paid $8.5M in duties in July 2026 — an effective duty rate of 16% on $53.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Mechanical Appliances for Projecting or Spraying Liquids or Powders (NESOI) imports of $65.7M in July 2026 ran 22% above the year-to-date monthly average of $53.9M.
Last updated: July 2026 dataOutside of agricultural use and fire suppression, a wide range of industrial liquid and powder projecting equipment — including conformal coating machines for printed circuit boards, industrial humidifiers, and chemical dosing systems — falls under this residual heading. The US schedule specifically breaks out appliances for spraying printed circuits and assemblies (8424891000), reflecting the electronics manufacturing sector's distinct classification needs, alongside a general NESOI line (8424899000). China and Mexico are the top suppliers, with Germany and South Korea also significant sources for precision industrial equipment. Section 301 tariffs apply to Chinese-origin goods across most lines in this heading.

Conformal coating and selective soldering flux-application machines used in electronics manufacturing have distinct technical specifications and trade flows compared to general industrial spray equipment. The dedicated line (8424891000) allows CBP and trade analysts to track this electronics-sector equipment separately and apply any targeted trade-remedy measures with greater precision.
When a machine performs multiple functions, classification follows GRI 3, which directs classification to the heading that most specifically describes the article, or — if that test is inconclusive — to the heading for the component that gives the machine its essential character. For a unit where liquid projection is the primary commercial function, 8424.89 is likely correct, but a CBP binding ruling is advisable for high-value or high-volume imports.
