4 Explain the effects of an import quota on domestic production, consumption and price. Non-tariff policies include health, safety and regulation barriers. Thousands of detailed health, safety and other regulations restrict international trade. For example, the EU bans imports of most genetically modifi ed foods such as US-produced soya beans. The EU also uses Geographical Indicators, which restrict the use of well-known food and drink names to specifi c areas such as Feta cheese to Greece. Although such regulations are not designed to limit international trade, they have that effect and may now be as important as tariffs.
