Importers of Parts of Furnace Burners, Stokers, Grates & Ash Dischargers paid $786K in duties in April 2026 — an effective duty rate of 13% on $6.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataReplacement and OEM parts for liquid-fuel, gas, and combination burners — as well as for mechanical stokers, grates, and ash dischargers — all consolidate under a single 10-digit line (8416900000), making this a catch-all parts heading for industrial combustion equipment. Germany leads US imports, reflecting the dominance of German OEMs in the industrial burner market, with Canada and China also significant sources. Classification challenges arise when a component could equally be argued as a part of a boiler (heading 8403 or 8404) versus a part of a burner; the key test is whether the part is principally designed for the burner/stoker mechanism itself.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP applies the principal-use test: if the component is specifically designed and marketed for use in the burner or stoker mechanism (e.g., a burner nozzle, igniter, or grate bar), it classifies under 841690. Generic components such as valves or pumps that serve the broader boiler system may fall under their own headings. Technical drawings and OEM part numbers are key supporting documents.
Yes, parts of furnace burners originating in China are generally subject to Section 301 tariffs. Germany and Canada are the leading alternative sources, and Canadian-origin goods may qualify for USMCA treatment. Importers should confirm origin and applicable orders with a licensed customs broker.
