HS Code 8416.90 – Furnaces; parts of furnace burners, for liquid fuel, pulverized solid fuel or gas, mechanical stokers, grates, ash dischargers and the like
HS code 8416.90 is the 6-digit subheading for furnaces, parts of furnace burners, for liquid fuel, pulverized solid fuel or gas, mechanical stokers, grates, ash dischargers and the like. It is used for burner nozzles, flame sensors, igniters, refractory linings (for burners) and grate bars.
What HS 8416.90 covers
This HS code serves as a comprehensive category for parts of the various industrial furnace burners, mechanical stokers, grates, and ash dischargers classified under heading 8416. It is critical for the maintenance, repair, and upgrade of existing industrial heating infrastructure across diverse sectors such as power generation, petrochemicals, cement, and manufacturing. Importers are typically industrial facilities, maintenance companies, or distributors who require specific components to ensure the continuous and efficient operation of their combustion equipment. Exporters are often the original equipment manufacturers (OEMs) or specialized parts suppliers. Accurate classification hinges on clearly identifying the specific furnace or burner model the part is designed for, as these components are highly specialized and not interchangeable with general machinery parts.

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).
