Certain basic and processed products in the agricultural sector are subject, not only to customs duties, but also to other charges under the Common Agricultural Policy (CAP) of the EU. The purpose of CAP charges is to protect EU-produced goods by increasing entry prices, so that non-Union goods come in line with the generally higher prices in the customs territory of the Union. The rates are changed annually and are published in the tariff. Additional safeguard measures and charges may also be imposed in exceptional circumstances to give extra protection to EU production.
The CAP charge regime is administered by the Rural Payments Agency.
