Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unworked or shaped mica sheets
Raw or minimally processed mica plates without electrical insulator treatment fall under worked mineral products.
If crude natural mica splittings
Unprocessed mica splittings are classified as crude minerals rather than fabricated insulators.
