Non-tariff Barriers

Instruments other than import tariffs that restrict international trade.

Some examples of non-tariff barriers are quotas, import bans, packaging conditions, occupational safety and health regulations,rules of origin, and restrictive licensing. For example, New Zealand's apples account for 1/3 of its agricultural exports but have been banned from Australia since 1921 due to fears about the spread of fire blight, a crop pest.
