SITCSection 7
U.S. imports of electronic valves and tubes (other) (SITC 77627) totaled $2.4M in April 2026, traded with 25 countries.
Importers of Electronic Valves and Tubes (Other) paid $440K in duties in April 2026 — an effective duty rate of 19% on $2.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Electronic Valves and Tubes (Other) imports of $2.4M in April 2026 ran 18% below the year-to-date monthly average of $2.9M.
Last updated: April 2026 dataElectron tubes not elsewhere specified under SITC 77627 encompass a broad residual group — including receiving tubes, transmitting tubes, and specialized vacuum devices that do not fit the CRT, microwave, or photosensitive categories. Audio amplifier tubes (often called 'valves' in British trade terminology) for high-fidelity equipment are a commercially active segment within this heading, driven by audiophile and professional audio markets. Correct classification requires distinguishing the tube's operating principle and primary application from the more specific headings that precede it in the SITC schedule.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Generally yes — receiving-type triodes, pentodes, and other audio amplifier valves that are not CRTs, microwave tubes, or photosensitive devices fall into the residual 77627 category. Importers of audiophile tubes should confirm the specific HTS 10-digit subheading at entry, as some high-power transmitting types may be classified differently based on their rated dissipation.
CBP may request the manufacturer's technical datasheet showing the tube type designation, operating frequency range, anode dissipation rating, and intended application. Demonstrating that the article does not meet the definitional criteria of any more specific heading — CRT, microwave tube, or photosensitive device — is the key to sustaining an NES classification. A binding ruling from CBP can provide advance certainty for recurring shipments.
