Last updated: August 2026 dataProcessed mica and mica-based articles not elsewhere specified enter the US under a single 10-digit line, 6814900000, covering a wide range of fabricated forms used in electrical insulation, cosmetics, and specialty industrial applications. Vietnam leads US supply, followed by China and Austria, reflecting both low-cost sheet-splitting operations and high-precision European fabrication. Importers should verify whether the article qualifies as mica splittings, built-up mica, or a finished article, as classification boundaries with other headings in Chapter 68 can affect duty treatment. The diversity of end-use sectors — from electronics to personal care — means specification documentation is critical at entry.

Worked mica generally refers to mica that has been processed (split, ground, or shaped) but not yet assembled into a finished product, while articles of mica are completed goods made from mica as a primary material. The distinction matters because some intermediate forms may classify elsewhere in Chapter 68 or even Chapter 85 if they are specifically designed electrical components. Consulting a licensed customs broker is advisable when the product sits on the boundary between these forms.
Vietnam and China tend to supply high-volume, labor-intensive forms such as mica splittings and sheet products, while Austria, Germany, and the United Kingdom supply precision-engineered mica composites and specialty insulation articles for industrial and high-tech applications. This split reflects the material's dual role as both a commodity mineral and a performance-critical engineered input.
