HTS heading 2525 is a broad product category for mica and certain mica-based materials. It covers mica in its natural form, mica split into thin layers or sheets (often called mica splittings), and waste or scrap generated from processing mica. The heading groups these goods together, but it does not by itself provide the complete tariff classification.
To reach the correct 8-digit HTSUS code, start by identifying the product’s physical form and commercial description. Subheadings commonly distinguish goods by the type of mica, such as whether it is worked or unworked, split into layers, ground or otherwise processed, or presented as waste. Review the applicable subheading text, legal notes, and the product’s actual composition and condition; a customs broker or classification specialist may be needed for unusual or processed products.
What to check
- Confirm that the product is actually mica, rather than an imitation, composite, or a different mineral.
- Record the mica type, including its mineral variety when known, and whether it is natural, worked, split, ground, or otherwise processed.
- Check whether the merchandise is a finished product or merely mica material; articles made with mica may classify outside heading 2525.
- Distinguish usable mica material from processing waste or scrap, and document how the goods are described commercially.
- Compare the product’s specifications, photos, samples, and supplier information with the current HTSUS subheading language before choosing the 8-digit code.

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.
