Product classification
HS code for Microwave magnetron: 8540.71
Tubes, microwave, magnetrons, excluding grid-controlled tubes.
Classification of microwave magnetron under HS 8540.71
Microwave magnetrons are classified under HS code 8540.71. This classification is situated within Chapter 85, which encompasses electrical machinery and equipment and parts thereof. Heading 8540 is specifically reserved for thermionic, cold cathode, or photo-cathode valves and tubes, including vacuum or gas-filled valves and tubes. Within this heading, subheading 8540.71 is dedicated to magnetrons, excluding grid-controlled tubes. A magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities. In the context of microwave ovens, the magnetron is the critical component responsible for producing the electromagnetic radiation that heats the food. According to the Section XVI Note 2(a), 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. Since magnetrons are specifically named under heading 8540, they must be classified there rather than as general parts of a microwave oven under heading 8516. This specific designation takes precedence over more general parts categories, ensuring uniform classification across international borders.

Codes often confused with 8540.71
Common mistake. The most common misclassification for a magnetron is HS code 8516.90, which covers parts of domestic electro-thermic appliances. While a magnetron is a part of a microwave, the Harmonized System rules state that if a part is specifically listed under its own heading (like 8540 for thermionic tubes), that specific heading must be used. Another potential error is confusing magnetrons with other microwave tubes like klystrons or traveling-wave tubes, which are classified under HS code 8540.79.
Top exporters and importers of HS 854071 (the code used for microwave magnetron), 2025
In 2025, the largest exporter of HS 854071 (the code used for microwave magnetron) 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).

Questions about microwave magnetron
What is the HS code for Microwave magnetron?
The HS code for Microwave magnetron is 854071 (Tubes; microwave, magnetrons, excluding grid-controlled tubes). The HS code for a microwave magnetron is 8540.71.
How do I classify Microwave magnetron for customs?
Microwave magnetron is classified under HS code 854071 — Tubes; microwave, magnetrons, excluding grid-controlled tubes. This is a 6-digit subheading level code.
Can magnetrons be classified as general microwave parts?
No, because magnetrons are specifically identified as thermionic tubes under heading 8540, they cannot be classified under the general parts heading 8516.90.
Which countries are the top exporters of microwave magnetron (HS 854071)?
In 2025, the top exporters of HS 854071 (the code used for microwave magnetron) in UN Comtrade data were the United Kingdom ($85M, 23% of world exports), the Netherlands ($58M) and the United States ($51M). World exports came to about $363M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
