2525.10.00.20 - Mica splittings

This HTS category, 2525.10.00.20, specifically covers mica splittings. These are thin, flexible sheets of mica that have been produced by cleaving or splitting larger pieces of mica. Mica splittings are characterized by their ability to be laid down in overlapping layers and are often used as an insulating material due to mica's excellent dielectric properties and thermal stability.

It is important to distinguish mica splittings from its sibling category, 2525.10.00.10, which classifies split block mica. While both involve splitting mica, "split block mica" generally refers to larger, more regular sheets or blocks that have been rifted but retain a more substantial form, whereas "splittings" are typically much thinner and more delicate. The key differentiator lies in the degree of splitting and the resulting physical form and intended use.

As this is a leaf node within the HTS, there are no further subcategories under 2525.10.00.20. Therefore, classification within this code relies on identifying the material as mica that has been processed into thin, flexible splittings, distinct from larger split blocks or crude mica forms.
