HS Code 8540.71 – Tubes; microwave, magnetrons, excluding grid-controlled tubes
HS code 8540.71 is the 6-digit subheading for tubes, microwave, magnetrons, excluding grid-controlled tubes. It is used for microwave oven magnetrons, radar system magnetrons, industrial heating magnetrons, medical therapy magnetrons and high-power pulsed magnetrons.
What HS 8540.71 covers
This HS code specifically covers magnetrons, which are a type of microwave tube used to generate high-power microwave radiation. Their primary application is in microwave ovens, but they are also critical components in radar systems, industrial heating, and medical equipment. The international trade of magnetrons is significant, driven by the global manufacturing of consumer appliances and defense systems. Major importers include appliance manufacturers, defense contractors, and industrial equipment producers. Exporters are typically countries with strong electronics manufacturing bases and expertise in vacuum tube technology. Key considerations include power output, frequency stability, lifespan, and cost-effectiveness for consumer applications, while military applications demand extreme reliability and specific performance under harsh conditions. The market is mature for consumer-grade magnetrons but highly specialized for industrial and military variants.

Codes often confused with 8540.71
Common mistake. This code is specific to magnetrons. It should not be confused with other microwave tubes like klystrons (854079) or complete microwave ovens (851650) or radar apparatus (852610), as 854071 is only the magnetron component.
Top exporters and importers of HS code 854071, 2025
In 2025, the largest exporter of HS code 854071 in UN Comtrade data was the United Kingdom, with 23% of world exports; the largest importer in UN Comtrade data was China, with 14% 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).
