Quartz & Quartzite, Crude or Roughly Trimmed imports of $4.5M in April 2026 ran 61% above the year-to-date monthly average of $2.8M.
Last updated: April 2026 dataHigh-purity quartz and quartzite in crude or minimally processed form — excluding natural sands — serve as critical feedstocks for semiconductor-grade silicon, optical glass, and refractory materials. The classification distinguishes this mineral from processed silica products, making correct tariff placement essential when shipments arrive as rough blocks or sawn rectangular slabs. Demand is closely tied to the electronics and solar-panel manufacturing sectors, where silica purity specifications drive sourcing decisions.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Natural sands are explicitly excluded from this heading regardless of silica content. Crude quartz and quartzite qualify here when presented in lump, block, or sawn rectangular/square slab form without further processing such as grinding or purification.
Semiconductor fabrication (crucibles and wafer production), solar photovoltaic manufacturing, specialty glass, and refractory linings are the primary end-use sectors. Purity grade and particle size requirements often dictate supplier selection more than price alone.
