854079

Tubes; microwave (for example klystrons, travelling wave tubes, carlinotrons), excluding magnetrons and grid-controlled tubes

Heading 8540Thermionic, cold cathode or photo-cathode valves and tubes (e.g. vacuum, vapour, gas filled valves and tubes, mercury arc rectifying valves and tubes, cathode-ray and television camera tubes)

Chapter 85: Electrical machinery and equipment

Plain-language overview

Use HS-6 854079 when importing or exporting microwave tubes such as klystrons and travelling wave tubes. For example, if you're shipping klystron tubes used in radar systems, this is the correct code to use.

This code specifically covers microwave tubes, which are essential in various applications, including telecommunications and scientific research. In contrast, HS-6 854078 includes magnetrons, which are used in microwave ovens and have different specifications.

Klystrons and travelling wave tubes are designed to amplify microwave signals and are often found in satellite communications and broadcasting. If your product falls under these categories, ensure you're using HS-6 854079.

When classifying your products, note that this HS-6 line excludes grid-controlled tubes, which are classified separately. Understanding these distinctions can help avoid misclassification and potential customs delays.
