Import Tips
• Declare microwave tunnel diodes under 8541.10.00 and include the peak current and frequency range in the technical documentation
• Since these are legacy components, ensure the supplier provides full specifications to support classification
• Consider whether the diodes are for research or commercial use, as this may affect import procedures
