Last updated: April 2026 dataProcessed cork in particulate form — whether derived from manufacturing waste or from deliberate size-reduction of raw bark — is classified here, with the US schedule separating waste cork (4501902000) from deliberately crushed, granulated, or ground cork (4501904000). Granulated and ground cork are key inputs for agglomerated cork products, acoustic and thermal insulation panels, and composite flooring underlays, giving this heading an industrial character distinct from the decorative and closure applications of finished cork articles. Portugal and Spain remain the dominant origin countries for processed cork inputs, reflecting the geographic concentration of cork oak cultivation in the Iberian Peninsula.

Waste cork (4501902000) refers to offcuts, trimmings, and byproduct material generated during the manufacture of cork articles — it is a residual material rather than a deliberately produced product. Crushed, granulated, or ground cork (4501904000) is intentionally size-reduced cork produced as a commercial end product for use in insulation, flooring, or agglomeration. The distinction turns on whether the particulate form results from a manufacturing byproduct or a deliberate processing step.
Processed cork that has been heat-treated or otherwise subjected to industrial processing may have different phytosanitary risk profiles than raw bark, and APHIS requirements can vary accordingly. Importers should consult current APHIS regulations and, where applicable, obtain phytosanitary certificates from the exporting country. A licensed customs broker or APHIS-accredited agent can confirm the current entry requirements for the specific processing method and country of origin.
