Last updated: August 2026 dataRaw and minimally processed natural cork — harvested primarily from the bark of Quercus suber (cork oak) — enters the US under a single 10-digit line (4501100000) and serves as the upstream input for the wine stopper, insulation, and flooring industries. Portugal and Spain together account for the overwhelming majority of global cork oak forests and dominate world supply of raw cork, making this a geographically concentrated commodity with limited origin diversification. The 'simply prepared' threshold is a key classification boundary: cork that has been debacked, squared, or cut into blanks moves to heading 4502, while crushed or granulated cork shifts to heading 4501.90.

Heading 4501 covers cork in its natural state or after minimal operations such as cleaning, trimming, or boiling to improve elasticity — processes that do not alter the basic form of the bark slabs. Once cork is debacked (outer bark removed), roughly squared, or cut into rectangular blocks, plates, or sharp-edged blanks for stoppers, it crosses into heading 4502. The distinction is important because the two headings carry different duty rates.
Raw natural cork is a plant product and is subject to USDA APHIS phytosanitary requirements. Shipments may require a phytosanitary certificate from the exporting country's national plant protection organization, and APHIS may conduct inspection at the port of entry. Importers should confirm current APHIS entry requirements for cork bark from the specific country of origin before shipment.
