HS Code 8514.19 – Furnaces and ovens; electric, for industrial or laboratory use, resistance heated; other than hot isostatic presses, for the manufacture of semiconductor devices on semiconductor wafers

HS code 8514.19 is the 6-digit subheading for furnaces and ovens, electric, for industrial or laboratory use, resistance heated, other than hot isostatic presses, for the manufacture of semiconductor devices on semiconductor wafers. It is used for diffusion furnaces for wafers, oxidation furnaces for semiconductors, annealing furnaces for wafers, CVD furnaces for semiconductor devices and rapid thermal processing (RTP) systems.

What HS 8514.19 covers

This HS code is highly specific, covering electric resistance-heated furnaces and ovens used in industrial or laboratory settings, *other than hot isostatic presses*, that are designed for the manufacture of semiconductor devices on semiconductor wafers. These specialized furnaces are fundamental to the microelectronics industry, performing critical processes like diffusion, oxidation, and annealing in a controlled environment. They are essential for creating the intricate layers and structures on silicon wafers that form integrated circuits. Major exporters are leading semiconductor equipment manufacturers, primarily from Japan, the USA, and Europe, while importers are the global semiconductor fabrication plants (fabs) in Asia and other regions. Key considerations include ultra-high purity environments, precise temperature uniformity, and integration into complex cleanroom production lines, reflecting the cutting-edge nature of semiconductor manufacturing.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
