U.S. exports of Magnetron Microwave Tubes (HS 854071) totaled $4.0M in August 2026.
Importers of Magnetron Microwave Tubes paid $492K in duties in August 2026, an average duty rate of 15.19% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataMagnetrons are vacuum-tube oscillators that generate microwave-frequency energy, serving two distinct markets captured in the US tariff schedule: consumer microwave oven magnetrons (8540712000) and all other magnetron types (8540714000), which include industrial heating, radar, and medical linear accelerator applications. The oven-grade and industrial-grade lines differ substantially in power output, frequency stability, and construction, making the intended application a critical classification factor. The United Kingdom and China lead US import supply, with Japan and Thailand also significant sources—a supplier mix reflecting both legacy British microwave-tube expertise and high-volume Asian consumer-appliance production.

The oven-modified line (8540712000) covers magnetrons specifically designed or modified for use in consumer or commercial microwave ovens, typically characterized by fixed frequency near 2.45 GHz and relatively low power output. Magnetrons for radar, industrial heating, medical accelerators, or other non-oven applications fall under 8540714000 regardless of their operating frequency. The manufacturer's application specification or datasheet is the primary evidence for classification.
High-power magnetrons used in radar or certain industrial applications may be controlled under the Export Administration Regulations based on frequency range and peak power output. Importers planning to re-export should screen the specific device against the Commerce Control List, and end-use certificates may be required for certain destinations or end users.
