2525.10.00 - Crude mica and mica rifted into sheets or splittings

This HTS category, 2525.10.00, encompasses crude mica and mica that has been processed by splitting into sheets or splittings. Crude mica refers to mica in its raw, unworked state as extracted from the earth. Mica rifted into sheets or splittings signifies mica that has undergone initial mechanical or manual separation into thin, flat layers or partial layers. This classification is specifically for mica in these primary processed forms, suitable for further manufacturing or direct use in applications requiring thin mica layers.

It is crucial to distinguish this category from its siblings. HTS code 2525.20.00.00 covers mica powder, which is mica that has been ground or pulverized into fine particles, a significantly different physical state and form. Similarly, 2525.30.00.00 addresses mica waste, which pertains to discarded or scrap mica materials not fit for primary processing into sheets or splittings. Therefore, 2525.10.00 is reserved for the semi-finished sheet and splitting forms of mica.

Within 2525.10.00, further subdivisions exist to refine the classification based on the specific form of mica sheets and splittings. The subcategories include "Split block mica" (2525.10.00.10), referring to larger, relatively thicker sheets that have been split; "Mica splittings" (2525.10.00.20), which are thinner and often irregular in shape, intended for building up composite mica products; and "Other" (2525.10.00.50) for any crude or split mica not specifically covered by the preceding subheadings. These distinctions allow for more precise tariff assessment based on the degree of processing and the intended end-use of the mica product.
