I thought all EU countries are in the EU customs union.
Of course they are.
Of course!
Was just a try to correct someone politely ;)

EU law is supranational and overrides national law.
EU regulations override national law, with immediate effect upon being effective.
EU directives take effect only upon being implemented (the technical term is “transposed”), jurisdiction by jurisdiction, by a law/regulation/decree/… of that jurisdiction. Member States have the obligation to implement EU directives into national law within a specific deadline, but if they fail to do so, you cannot rely on the directive directly in front of courts. The only thing you can do is complain to the European Commission, which will formally serve notice to the Member State, and possibly start the process of imposing penalties (fines) on the Member State in question.
