2525.10.00

Analysis

HTS 2525.10.00 covers crude mica and mica rifted into sheets or splittings under heading 2525 (mica, including splittings; mica waste). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.

There is no general-rate duty on this line, which puts it with roughly 91% of the 78 tariff lines in chapter 25 that are also free. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.

The other lines in the same group are 2525.20.00 (mica, including splittings; mica waste: mica powder, duty-free) and 2525.30.00 (mica, including splittings; mica waste: mica waste, duty-free).

Census statistics map these goods to NAICS 21239 (Other Nonmetallic Mineral Mining and Quarrying), an industry of 236 US establishments employing 10,238 people, the industry a domestic producer of these goods reports under.

The ten-digit suffixes separate split block mica and mica splittings. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
