Trade restriction

A trade restriction is an artificial restriction on the trade of goods and/or services between two countries. It is the byproduct of protectionism. However, the term is controversial because what one part may see as a trade restriction another may see as a way to protect consumers from inferior, harmful or dangerous products. For instance Germany required the production of beer to adhere to its purity law. The law, originally implemented in Bavaria in 1516 and eventually becoming law for newly unified Germany in 1871, made many foreign beers unable to be sold in Germany as "beer". This law was struck down in 1987 by the European Court of Justice, but is still voluntarily followed by many German breweries.
