Imports from third countries were subject to variable import duties prior to the introduction of the GATT/WTO (WTO) agreement on 1 July 1995. These taxes are now converted into a fixed tariff, payable in euros per tonne or as a percentage of the entry price. Under the agreement, rates were reduced by an average of 36% compared to the 1986-1988 reference period. In addition, the GATT/WTO agreement provides minimum quotas for access to tariffs at reduced rates of 5% of consumption over the reference period. In addition, the European Union is obliged to grant access to butter originating in New Zealand at a very low rate. This amount is the average amount of Annual exports from New Zealand to the United Kingdom under bilateral agreements during the GTT and WTO base period. Following the commitments of THE GATT and the WTO, the European Union has concluded a series of bilateral agreements aimed at facilitating market access on a reciprocal basis. For example, there are special quotas for the United States, Canada, Norway, Switzerland, South Africa and others. The GATT came into force on January 1, 1948. From the beginning, it was refined, which eventually led to the creation, on 1 January 1995, of the World Trade Organization (WTO), which absorbed and expanded it. To date, 125 nations signed its agreements, which covered about 90% of world trade. In May 1963, ministers agreed on three negotiating objectives: the GATT had three main provisions.

The most important requirement was that each member be obliged to confer the status of the most favoured country on any other member. All members must be treated the same with respect to tariffs. It excluded special tariffs between members of the British Commonwealth and the Customs Union. It allowed tariffs if their removal causes serious damage to domestic producers. The working hypothesis for collective bargaining was a linear reduction of 50% in tariffs, with the smallest number of exceptions. A long-term argument has developed about the trade effects of a uniform linear reduction on the dispersed rates (low tariffs and high rates quite far away) of the United States compared to the much more concentrated rates of the EEC, which also tended to be under the ownership of U.S. tariffs. Reducing tariffs and introducing new rules to stem the increase in non-tariff barriers and voluntary export restrictions. 102 countries participated in the cycle.

Concessions have been made for $19 billion. The fifth cycle was held again in Geneva and lasted from 1960 to 1962. The discussions were named after U.S. Treasury Secretary and former Undersecretary of State Douglas Dillon, who first proposed the talks. Twenty-six countries participated in the cycle. In addition to reducing tariffs by more than $4.9 billion, it has also led to discussions on the creation of the European Economic Community (EEC). This series of meetings and reduced rates would continue, allowing for new GATT provisions in the process. The average tariff rate rose from about 22% when the GATT was first signed in Geneva in 1947, to about 5% until the end of the 1993 Uruguay Cycle, which also negotiated the creation of the WTO.
