HTS heading 6814 is a four-digit product category for worked mica and articles made from mica. It includes natural mica that has been processed beyond its basic mineral form, as well as agglomerated or reconstituted mica, meaning mica particles or flakes bonded or formed into a usable material. The category can also include these products when they are mounted on paper, paperboard, or another support material.
The four-digit heading is only the starting point; it does not usually provide the complete tariff classification. To reach the specific eight-digit HTSUS code, follow the subheading descriptions under heading 6814 and match the merchandise by its material and physical type, such as whether it is sheet, plate, film, fabricated article, or another specified form. Review the product as imported, including its composition, construction, dimensions, and intended use. A customs broker or classification specialist may be needed when the product does not clearly fit one subheading.
What to check
- Confirm that mica is the essential material and identify whether it is natural, agglomerated, or reconstituted.
- Describe the imported form precisely, including sheets, plates, cut pieces, fabricated parts, or other articles.
- Check whether paper, paperboard, plastic, or another support is attached, and determine how the tariff text treats that construction.
- Read every applicable eight-digit subheading and its legal notes; do not select a code based only on a product name or marketing description.
- Keep composition records, technical specifications, drawings, photographs, and samples available to support the classification.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
