U.S. exports of Mica Waste (HS 252530) totaled $38K in August 2026, exported to 1 country.
Last updated: August 2026 dataMica waste — comprising trimmings, punchings, and processing residues from mica fabrication — is a lower-value input used primarily in ground mica production, wallboard joint compounds, and agricultural applications. India and Brazil are the leading suppliers, reflecting their roles as major mica-mining and processing nations. All US imports enter under the single line 2525300000, and the key classification question is distinguishing genuine processing waste from intentionally milled mica powder (252520).
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP may request a product data sheet, sieve analysis, or manufacturer's declaration confirming that the material is a processing residue rather than a deliberately milled product. Mica waste typically lacks a controlled particle-size specification and is priced significantly below commercial-grade mica powder. A binding ruling from CBP is advisable if the material is borderline.
Mica waste is reground into low-grade mica powder for use in joint compounds, roofing materials, and rubber compounding. It also serves as a soil conditioner in some agricultural applications. Because it is a by-product stream, supply availability and quality can vary with production levels at upstream mica fabrication facilities in India and Brazil.
