Sweden is a member of the European Union, so British businesses are free to import and export goods to the Swedish market without restrictions.
Sweden has a population of 9,658,301. Its capital is Stockholm and its currency is the Swedish Krone (SEK)
Most of Sweden’s main shipping ports are in the south and south-east of the country, the most important being Gothenburg, Stockholm and Helsingborg. The port of Pitea serves the north of the country but is not accessible to shipping during the winter months.
Sweden is a member of the EU, as is the UK (at present) and is part of the European single market. Therefore, British businesses have no restrictions, customs charges or additional tariffs to pay when shipping goods to or from Sweden. So long as duty and relevant taxes, such as VAT, are paid on your goods according to UK requirements, you will not face any additional charges doing business in Sweden. The same principle applies to British companies doing business in Finland and Denmark, which are also EU members.
Sweden is subject to the same import restrictions as other EU countries. It is not lawful to import protected species as listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

You also cannot import meat or milk products from a non-EU country into Sweden.
