HS Code for Electron tube

The classification of electron tubes under HS code 8540.81 is determined by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically focusing on the functional nature of thermionic, cold cathode, or photo-cathode valves and tubes. Heading 8540 covers a wide range of vacuum-based electronic components. Subheading 8540.81 is specifically reserved for receiver or amplifier valves and tubes. These devices operate by controlling the flow of electrons in a vacuum or gas-filled enclosure, a technology distinct from solid-state semiconductors. The classification depends on the tube's primary function within a circuit, which in this case involves the reception or amplification of electrical signals. This code is essential for customs authorities to distinguish between older vacuum technology and modern integrated circuits, ensuring appropriate duty rates and regulatory compliance are applied to legacy equipment and specialized high-fidelity audio components.

Products Included

• Vacuum triodes used in radio receivers
• Pentode amplifier tubes
• Beam power tubes for audio amplification
• Glass or metal envelope receiver tubes
• Vacuum-based signal processing tubes

Common Misclassification

Electron tubes are frequently misclassified under HS code 8541, which covers diodes, transistors, and similar semiconductor devices. The primary distinction is that 8541 is for solid-state electronics, while 8540 is for vacuum or gas-filled tubes. Additionally, cathode-ray tubes (CRTs) for televisions or monitors are classified under 8540.11 or 8540.12, and should not be confused with the general receiver or amplifier tubes found in 8540.81.

FAQ

What is the HS code for electron tube?

The specific HS code for receiver or amplifier electron tubes is 8540.81.

How do I distinguish between 8540 and 8541?

HS code 8540 is used for vacuum-based technology (valves and tubes), whereas 8541 is used for modern solid-state semiconductor devices like transistors and silicon diodes.
