The transitional period for the REX system has expired for the following countries:
Angola, Burundi, Bhutan, Democratic Republic of Congo, Central African Republic, Comoros, Congo, Cook Islands, Djibouti, Ethiopia, Micronesia, Equatorial Guinea, Guinea Bissau, India, Kenya, Kiribati, Laos, Liberia, Mali, Nauru, Nepal, Niue Island, Pakistan, Solomon Islands, Sierra Leone, Somalia, South Sudan, Sao Tomé & Principe, Chad, Togo, Tonga, Timor-Leste, Tuvalu, Yemen, Zambia will have to fully apply the REX system from 1st July 2018.
The European Commission informs European Union operators that “only ‘statements on origin’ made out by exporters registered in these GSP (Generalised System of Preferences) exporting countries or territories, or made out by any exporter of these countries or territories where the total value of the originating products consigned does not exceed EUR 6 000, can be used to certify the preferential origin of the goods since 1 July 2018.
GSP preferences will therefore be denied in case FORM A certificates issued after 1 July 2018 are presented as proofs of GSP preferential origin. GSP preferences will also be denied in case invoice declarations made out after 1 July 2018 are presented as proofs for GSP preferential origin for consignments containing originating products whose total value does not exceed EUR 6 000.
The operators presenting documentary proofs of origin in the European Union in the framework of the GSP are therefore advised to take all the necessary measures and precautions to ensure that their suppliers in the GSP beneficiary countries or territories mentioned above are alerted about the change of procedure as regards the proofs of preferential origin and about the consequences in case an incorrect proof of origin (FORM A certificate or invoice declaration) is presented »
