HS Code 8417.90 – Furnaces and ovens; parts of non-electric furnaces and ovens (including incinerators), of industrial or laboratory use
HS code 8417.90 is the 6-digit subheading for furnaces and ovens, parts of non-electric furnaces and ovens (including incinerators), of industrial or laboratory use. It is used for refractory bricks, furnace linings, oven doors, temperature sensors (specific to furnace) and kiln furniture.
What HS 8417.90 covers
This HS code covers parts specifically designed for the non-electric industrial and laboratory furnaces, ovens, and incinerators classified under heading 8417. These components are essential for the maintenance, repair, and longevity of critical industrial heating infrastructure across a wide array of sectors, including metallurgy, food processing, ceramics, glass, and waste management. Importers are typically industrial end-users, maintenance contractors, or distributors who require specific components to ensure the continuous and efficient operation of their heating equipment. Exporters are often the original equipment manufacturers (OEMs) or specialized parts suppliers. Accurate classification requires a clear understanding of the specific furnace or oven the part belongs to, as these components are highly specialized and crucial for operational integrity.

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).
