"In Spain products must comply with the standards laying down the quality requirements. These standards incorporate the relevant EU legislation. Where there is no EU legislation, products must comply with the standards of the country of origin.

Products must also comply with Spanish consumer protection rules. These also incorporate the European rules, for example on labelling.

In Spain goods can be freely imported from or exported to other Member States of the European Union."

But if goods come from outside the EU there are hurdles to jump.
