Product classification
HS code for Magnetron tube: 8540.71
Tubes, microwave, magnetrons, excluding grid-controlled tubes.
Classification of magnetron tube under HS 8540.71
Magnetron tubes are classified under HS code 8540.71 because they are a specific type of thermionic, cold cathode, or photo-cathode valve or tube. Specifically, they fall under the category of microwave tubes. These devices function as high-powered vacuum tubes that generate microwaves through the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities. This classification is determined by the General Rules of Interpretation (GRI), specifically GRI 1, which directs classification to the heading that most specifically describes the product. Since 8540 covers thermionic tubes and 8540.71 specifically names magnetrons, this is the correct designation. The classification remains consistent regardless of whether the tube is intended for industrial radar systems or consumer microwave ovens, provided it is imported as a standalone component. The technical nature of the vacuum tube, involving an internal cathode and anode structure within a vacuum envelope, is the primary factor in its placement within Chapter 85.

Codes often confused with 8540.71
Common mistake. Magnetron tubes are frequently misclassified under HS code 8516.90, which covers parts for domestic electro-thermic appliances like microwave ovens. While a magnetron is a component of an oven, Note 2 to Section XVI specifies that parts which are goods included in any of the headings of Chapter 84 or 85 are in all cases to be classified in their respective headings. Therefore, as a thermionic tube, it must stay in 8540. Another common error is using 8540.79, which is for other microwave tubes like klystrons or traveling wave tubes, but magnetrons have their own specific 6-digit subheading.
Top exporters and importers of HS 854071 (the code used for magnetron tube), 2025
In 2025, the largest exporter of HS 854071 (the code used for magnetron tube) 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).
