Laws and regulations in different countries frequently lead to obligatory product design adaptations. This may be seen most clearly in Europe, where one impetus for the creation of the single market was the desire to dismantle regulatory and legal barriers that prevented pan-European sales of standardized products. These were particularly prevalent in the areas of technical standards and health and safety standards. In the food industry, for example, there were 200 legal and regulatory barriers to cross-border trade within the EU in 10 food categories.
