HS-6 · Subheading
854089
Valves and tubes; n.e.c. in heading no. 8540
Heading 8540 — Thermionic, 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 854089 when importing or exporting thermionic, cold cathode, or photo-cathode valves and tubes that don’t fit other specific categories. For instance, if you're shipping a specialized vacuum tube used in a scientific instrument, this code applies.
This code falls under the broader heading 8540, which covers various types of valves and tubes, including common cathode-ray tubes. Unlike HS-6 854090, which is for cathode-ray tubes specifically for televisions, 854089 is for those that are not classified elsewhere.
When classifying products under HS-6 854089, consider items like gas-filled tubes or specialized rectifying valves. These components are often used in electronic circuits, amplifiers, and various industrial applications, distinguishing them from more common consumer electronics.
If you're unsure whether your product fits this code, compare it with HS-6 854090 for cathode-ray tubes or HS-6 854091 for specific types of rectifying tubes. Understanding these distinctions can help avoid misclassification.
