Last updated: April 2026 dataGranulated and ground cork — produced from waste trim generated during stopper and sheet manufacturing — is a widely traded industrial input used in flooring underlays, acoustic panels, gaskets, and cork composite boards. Particle size is the defining commercial specification: coarse granules suit flooring and construction applications, while fine-ground cork is blended into adhesives and specialty coatings. Because this material is derived from processing waste rather than virgin bark, it typically trades at a significant discount to shaped cork products and is less sensitive to cork oak harvest cycles.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The industry commonly segments granulated cork by sieve size — coarse (roughly 3–7 mm), medium (1–3 mm), and fine (under 1 mm) — though exact grade definitions vary by supplier and end-use specification. Flooring and insulation applications typically use coarser grades, while fine-ground cork is preferred for sealants and surface coatings.
Processed cork waste and granules that have been heat-treated or boiled during manufacture may face reduced phytosanitary scrutiny compared to raw bark, but USDA APHIS requirements depend on the degree of processing and the exporting country's pest status. Importers should confirm current entry requirements with APHIS or a licensed customs broker before shipment.
