2525.30.00.00 - Mica waste

This HTS category, 2525.30.00.00, specifically covers mica waste. This includes any form of mica that has been discarded, generated as a byproduct of processing, or is otherwise unsuitable for direct use in its crude or split forms. Examples may include mica scraps, dust, or unusable fragments resulting from mining, cutting, or manufacturing processes involving mica. The key characteristic is that these materials are no longer in a form suitable for direct application as crude mica or prepared splittings.

This classification distinguishes itself from its sibling categories by its designation as "waste." Category 2525.10.00.00, for instance, covers crude mica and mica that has been rifted or split into usable sheets or splittings, implying a higher degree of processing and intended use. Similarly, category 2525.20.00.00 deals with mica powder, which, while potentially a byproduct of processing, is specifically processed into a powdered form for its own distinct applications. Mica waste, therefore, represents materials prior to or beyond these forms of preparation.

As a leaf node within the HTS structure, there are no further subcategories beneath 2525.30.00.00. This means that all forms of mica waste fall under this single code. Classification professionals should ensure that the material is indeed solely waste mica, not a form of processed mica powder or still-usable crude/split mica, to correctly apply this designation.
