Most goods imported into the Netherlands from outside the EU are subject to VAT. The VAT will have to be paid by the importer at the time of clearing goods into the EU.
Customs duty is levied across the EU at the place where goods are cleared into ‘free circulation’ in the EU. Once duty (if applicable) and VAT has been paid by the importer, the goods are in free circulation and they can then be released for use in the EU market.
