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 raw mica sheets
Uncut or general-purpose mica classifies as worked mica products, not appliance parts.
If ceramic waveguide covers for industrial use
High-temperature ceramic covers for radar equipment fall under ceramic articles.
If parts of conventional electric ovens
Heat shields for traditional ovens use different materials and classify separately.

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
• Specify microwave frequency compatibility (2.45 GHz) and dielectric properties in technical documentation
• Include cut-to-size specifications matching common microwave models to prove dedicated use
• Avoid generic mica sheets, which classify under Chapter 25 as natural minerals
