HS code for Mechanical stoker: 8416.30
Furnace accessories, mechanical stokers, mechanical grates, mechanical ash dischargers and similar appliances.
Classification of mechanical stoker under HS 8416.30
Mechanical stokers are classified under HS code 841630 because they are specialized mechanical appliances designed to automate the feeding of solid fuel into a furnace. This classification falls within Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8416 covers furnace burners for liquid fuel, for pulverized solid fuel or for gas, as well as mechanical stokers, including their mechanical grates, mechanical ash dischargers, and similar appliances. The classification is determined by the mechanical nature of the device and its dedicated function in the combustion process of industrial or domestic furnaces. These devices are essential for maintaining consistent fuel levels and ensuring efficient combustion by regulating the input of coal, wood, or other solid fuels. According to the General Rules of Interpretation (GRI), specifically GRI 1, the classification is dictated by the terms of the headings and any relative section or chapter notes. Since these items are auxiliary to furnaces but possess distinct mechanical functions, they are grouped under 841630 rather than being classified as parts of the furnace itself.

Codes often confused with 8416.30
Common mistake. Mechanical stokers are frequently confused with liquid fuel burners (841610) or gas burners (841620). While all fall under heading 8416, 841630 is strictly for solid fuel systems and their mechanical handling components. Additionally, manual grates or simple iron castings used in furnaces are often misclassified here, but they should generally be classified under heading 7321 or 7322 depending on their material and design, as they lack the mechanical movement required for 841630.
Top exporters and importers of HS 841630 (the code used for mechanical stoker), 2025
In 2025, the largest exporter of HS 841630 (the code used for mechanical stoker) in UN Comtrade data was Italy, with 26% of world exports; the largest importer in UN Comtrade data was France, with 19% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
