Some types of certificates of origin are only certifying origin of the goods, but do not qualify for any preferential tariff treatment.
These certificates of origin are known as Non-Preferential Certificates of Origin.
On the other hand, some sort of certificates of origin not only evidence the origin of the goods, but also enable products to enjoy import tariff reduction or exemption.
These certificates of origin are known as Preferential Certificates of Origin.
Today I would like to mention the differences between non-preferential certificates of origin and preferential EUR1 movement certificate.
