Microwave Oven Magnetron Assembly
The magnetron assembly is the core component that generates microwaves in microwave ovens, converting electrical energy into electromagnetic waves for heating food. It falls under HTS 8514.90.4000 as a specific part designed exclusively for microwave ovens, which use dielectric loss for heat treatment. This replacement part is commonly imported for oven repairs.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a standalone microwave-generating tube without oven-specific mounting
Microwave tubes not assembled for ovens classify under cathode-ray or microwave tubes in 8540.
If for industrial induction heating applications outside domestic ovens
Parts for other dielectric or induction heat treatment equipment fall under the broader 8514 parts but different subheading.
If marketed as a component for laboratory food drying equipment
Lab heating apparatus parts may shift to 8419 if not specifically for microwave ovens.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify the part is exclusively for microwave ovens with manufacturer specs to avoid reclassification as general electronic parts
• Include detailed invoices specifying 'microwave oven part' and OEM compatibility to ensure proper HTS classification
