The most crucial step is to obtain a declaration of origin. If you are importing goods, they must be certified as being produced, at least in part, in EU countries and must meet the standards of the Protocol on rules of origin and origin procedures. The European exporter should provide you the declaration of origin.
Consequently, as a Canadian exporter into the European Union, you must in turn provide a declaration of origin and meet the standards of the same Protocol so that the European importer can be granted exemption from customs duties.
It is crucial to keep in mind that the exemption applies to most products, but not to all of them.
