About HS Code 854099

This is a residual category for parts of all other electronic valves and tubes under heading 8540, specifically excluding parts of cathode-ray tubes (which are covered by 854091). This includes components for vacuum tubes, magnetrons, klystrons, traveling wave tubes, and other specialized electronic tubes used in industrial, scientific, medical, and high-power communication applications. Trade in these parts is highly specialized, supporting the maintenance and manufacturing of niche electronic equipment. Exporters are typically countries with advanced manufacturing capabilities for precision electronic components, such as Japan, Germany, and the USA. Importers include manufacturers of specialized equipment, repair and maintenance facilities, and research institutions. Key trade considerations involve material specifications, precision manufacturing, and compatibility with the specific types of valves or tubes they are designed for, reflecting a critical segment of the specialized electronics supply chain.

Products Under This Code

Filaments for vacuum tubes, Grids for power tubes, Anodes for magnetrons, Ceramic insulators for high-power tubes, Glass envelopes (non-CRT), RF windows for microwave tubes, Cathode heaters

Real World Examples

Components for Eimac power tubes, Parts for Hamamatsu photomultiplier tubes, Replacement parts for industrial magnetrons, Components for specialized TWTs, Glass seals for vacuum tubes

Common Misclassification

This code is a catch-all for parts of valves and tubes other than CRTs. It's crucial to distinguish it from 854091 (parts of cathode-ray tubes) and from complete valves/tubes themselves (various 8540 subheadings).
