HS-4 · 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-4 8540 when importing thermionic, cold cathode, or photo-cathode valves and tubes, such as vacuum tubes or cathode-ray television picture tubes. For example, if you're bringing in a shipment of color cathode-ray tubes for televisions, this is the correct code.

To determine the right subheading, consider the specific type of tube. For instance, if your product is a monochrome cathode-ray tube, you would classify it under HS-6 854012. In contrast, color tubes fall under HS-6 854011. This distinction is crucial for accurate tariff classification and duty assessment.

If your shipment includes television camera tubes or image converters, you should use HS-6 854020. This line specifically covers photo-cathode tubes used in imaging applications, differing from the cathode-ray tubes meant for display purposes. Make sure to identify the end-use to select the correct subheading.

For microwave tubes, the choice between HS-6 854071 (magnetrons) and HS-6 854079 (other microwave tubes like klystrons) depends on the specific technology used. If you're importing magnetrons, choose 854071, while for klystrons, select 854079.
