HS Code 8416.30 – Furnace accessories; mechanical stokers, mechanical grates, mechanical ash dischargers and similar appliances
HS code 8416.30 is the 6-digit subheading for furnace accessories, mechanical stokers, mechanical grates, mechanical ash dischargers and similar appliances. It is used for traveling grates, vibrating grates, underfeed stokers, chain grate stokers and screw ash conveyors.
What HS 8416.30 covers
This HS code covers essential mechanical accessories for furnaces, particularly those handling solid fuels. It includes mechanical stokers, which automatically feed fuel into the furnace; mechanical grates, which support the fuel bed and allow air passage; and mechanical ash dischargers, which remove combustion byproducts. These appliances are crucial for optimizing the efficiency, automation, and environmental performance of industrial furnaces in sectors like power generation, waste-to-energy plants, and large-scale heating systems. Importers are typically industries heavily reliant on solid fuels, seeking to modernize their combustion processes, while exporters are specialized manufacturers of heavy industrial machinery. Key considerations for trade include durability, automation capabilities, and seamless integration with existing furnace designs to ensure reliable and continuous operation.

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).
