There is no customs duty on white goods and electric products, but there is value added tax. You must declare the goods on the border if you buy goods with a value over the value limit.
If you buy goods with a total value of less than the value limit, you are not liable to pay value added tax or other taxes. If you have purchased goods with a total value in excess of the value limit you must pay 25 per cent value added tax on the purchase price and shipping costs.
More than 24 hours
If you have been outside of Norway for more than 24 hours, you may bring goods with a value of up to NOK 6,000 with you without paying customs duty or taxes. This value limit is the sum total of the goods you have bought, including your duty free allowance.
Less than 24 hours
If your time abroad is shorter, you can bring with you once in the course of 24 hours goods with a total value of NOK 3,000 free of customs duties and taxes. This value limit is the sum total of the goods you have bought, including your duty free allowance.
