The European Commission has suggested that EU rules of origin, establishing from which country an imported product is legally produced or manufactured, be simplified to boost trade.

In a green paper, Brussels maintains these regulations are too complex.

This is specially the case with food, where a manufactured product may contain ingredients from many countries and be packaged and prepared in different states.

The paper said the Commission favoured a "value added test", where a manufactured product would be considered from the country of processing "if the value added…amounts at least to a certain threshold" set as a percentage of net production costs.
