It should be noted that many countries have implemented the REX Registered Exporter System, which is a system of self-certification of the origin of their products. This system simplifies the process for the exporter, because instead of asking for proof of origin from his authority, he can issue it himself through this system. Regional trade agreements are multiplying and changing in nature. Fifty trade agreements were in force in 1990. In 2017, there were more than 280. In many trade agreements, negotiations today go beyond tariffs and cover several policies that influence trade and investment in goods and services, including rules across the border, such as competition policy, government procurement rules and intellectual property rights. Sweden is a member of the EU and does not conclude free trade agreements on its own initiative. However, Sweden is actively involved in the preparations and work during the ongoing negotiations under the leadership of the EU. The mission of the National Board of Trade is to provide the Swedish government with qualified analysis for negotiating and making trade policy decisions. Sweden`s traditionally positive trade balance recorded a deficit in 2018, with imports growing faster than exports. Imports reached $170.2 billion in 2018 from $154.2 billion the year before, while exports rose from $152.9 billion over the period to $165.9 billion. .
