compensatory tax - a special import levy imposed by the European Economic Community on certain imports when the entry price of these products falls below a reference price
... national customs authorities should verify whether the minimum import price is being observed for each consignment imported and, in the event of that price not being observed, levy the countervailing charge which is equal to the difference between the minimum import price and the declared import price
Where in a Member State a product is subject to a national market organization or to internal rules having equivalent effect which affect the competitive position of similar production in another Member State, a countervailing charge shall be applied by Member States to imports of this product coming from the Member State where such organization or rules exist, unless that State applies a countervailing charge on export.
The compensatory charge shall be calculated according to the incidence on the value of the goods in question of the tariff disparities in respect of the raw materials or intermediate products in corporated therein.
