SITCSection 7
U.S. imports of mechanical stokers, grates, ash dischargers & similar appliances (SITC 74125) totaled $122K in April 2026, traded with 6 countries.
Importers of Mechanical Stokers, Grates, Ash Dischargers & Similar Appliances paid $12K in duties in April 2026 — an effective duty rate of 10% on $122K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataMechanical stokers automate the feeding of solid fuel—coal, biomass, or waste—into combustion chambers, while mechanical grates support burning material and ash dischargers remove residue, together forming the core of large-scale solid-fuel firing systems. These appliances are widely used in power generation, district heating, and industrial process plants where continuous, automated fuel handling is essential for operational efficiency. Classification turns on whether the unit is a complete stoker assembly or a standalone grate or discharger, as each may attract different duty treatment. Importers should confirm whether equipment meets applicable EPA emission-control standards before entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A mechanical stoker is a powered, integrated system that feeds fuel and moves it through the combustion zone; a mechanical grate alone supports burning material without fuel-feeding mechanisms. Both fall under this heading when designed as part of a stoker assembly, but standalone grates or dischargers sold separately may require careful classification review to confirm they remain within this heading rather than being classified as general mechanical parts.
While mechanical stokers are industrial equipment and do not trigger food or agricultural admissibility review, large combustion units may be subject to EPA New Source Performance Standards or state air-quality permitting requirements before installation. Importers should verify compliance with applicable emission regulations independently of the customs entry process.
