In short: goods traded between Morocco and the EU get preferential tariffs only with a valid proof of origin, either a movement certificate EUR.1 issued by customs or an origin declaration made out by the exporter. Since Decision No 1/2025 of the EU-Morocco Association Council took effect on 2 October 2025, two sets of origin rules apply side by side. A proof of origin is valid for ten months, exporters must keep the supporting file for at least three years, and if, in a case of reasonable doubt, the exporting country does not answer a verification request within ten months, the preference is refused save in exceptional circumstances. Law as at 2 October 2026.
This article follows our guide Customs, Rules of Origin and the EU–Morocco Association Agreement. It is about practice: which rules to apply, how to obtain or make out the proof, how cumulation works and what happens when customs check the proof afterwards. It is written for export managers, customs teams and in-house lawyers of manufacturers and importers trading in either direction.
The rules of origin are in Protocol 4 to the Euro-Mediterranean Association Agreement. The EU-Morocco Association Council amended Protocol 4 by Decision No 1/2025 of 2 October 2025, published in the Official Journal on 31 December 2025 (OJ L, 2025/2664). The Decision entered into force and applied from the date of its adoption, 2 October 2025 (Decision No 1/2025, Article 2).
Protocol 4 now provides two sets of rules:
An exporter may rely on either set, but each proof of origin is issued under one of them. A EUR.1 issued under the transitional rules must carry the words "REVISED RULES" in Box 7 (Appendix A, Article 20(3)), and the origin declaration text under those rules ends with the same words (Appendix A, Annex III). Before the first shipment under the new framework, confirm with the customs office of the exporting country which set it issues proofs under, and whether the amended Convention has been published in Morocco.
The two sets can be mixed only within limits. Cumulation requires that the materials obtained their origin under rules identical to those being applied (Appendix A, Article 8(1)(b)). As an exception, goods of HS Chapters 1, 3 and 16 (processed fishery products) and Chapters 25 to 97 that obtained origin under the Convention may still be cumulated under the transitional rules (Appendix A, Article 8(2)). Under the transitional rules, materials of other chapters that obtained origin under the Convention cannot be cumulated (Article 8(1)(b) and (2)).
Protocol 4 was amended again by Decision No 2/2025 of the EU-Morocco Association Council of 3 October 2025 (OJ L, 2026/242, 28.1.2026), which adds specific rules on how proofs of origin are completed for certain products. Exporters whose goods fall within that Decision should apply it alongside the rules described here.
Two further points from Decision No 1/2025. Proofs of origin may be issued retrospectively for exports made between 1 January 2025 and the entry into force of the amended Protocol (Protocol 4, new Article 4). For certain EU products listed in Appendix B, product-specific rules subject to tariff quotas apply for five years, and the proof must state "Derogation – Appendix B to Protocol 4" (Protocol 4, new Article 3; Appendix B, Article 1(1)).
The customs authorities of the exporting country issue the EUR.1 on a written application by the exporter or, under the exporter’s responsibility, its authorised representative (Appendix A, Article 20(1)). In Morocco this is the Administration des Douanes et Impôts Indirects (ADII); in the EU, the customs authority of the Member State of export.
Retrospective issue. A EUR.1 may be issued after export, for example after an error or involuntary omission, or where a certificate was refused at import for technical reasons (Article 21(1)). The application states the place and date of export and the reasons (Article 21(2)). Customs may issue it within two years of export, and it is endorsed "ISSUED RETROSPECTIVELY" in Box 7 (Article 21(3) to (5)).
Duplicates. If a EUR.1 is stolen, lost or destroyed, a duplicate endorsed "DUPLICATE" in Box 7 may be issued; it bears the date of the original and takes effect from that date (Article 22).
EUR-MED. The transitional rules provide for one certificate only, the EUR.1 (Appendix A, Article 17(1)(a) and Annex IV). The EUR-MED certificate of the former Protocol 4 is not part of these rules.
An origin declaration is a statement by the exporter on the invoice, delivery note or another commercial document. It may be made out (Appendix A, Article 18(1)):
The text is set out in Annex III and must be typed, stamped or printed on the commercial document (Article 18(4)). The English version under the transitional rules reads: "The exporter of the products covered by this document (customs authorisation No …) declares that, except where otherwise clearly indicated, these products are of … preferential origin. REVISED RULES". The declaration bears the exporter’s handwritten signature. An approved exporter may be exempted if it has given customs a written undertaking to accept full responsibility for any declaration that identifies it (Article 18(5)). A declaration may be made out after export if it is presented in the importing country within two years of import (Article 18(6)).
Approved exporter status. The customs of the exporting country may authorise an exporter established there to make out origin declarations regardless of value. The exporter must offer all guarantees needed to verify the origin of its products. Customs grant an authorisation number, which must appear on every declaration, and they may withdraw the authorisation if the exporter misuses it, and must withdraw it if the exporter no longer offers those guarantees (Appendix A, Article 19). For a regular exporter this is the most efficient route, because it removes the trip to customs for each shipment.
Not at present, as far as we have been able to establish. The transitional rules allow the parties to agree that EUR.1 certificates and origin declarations be replaced by statements on origin made out by exporters registered in an electronic database, and to allow proofs to be issued or submitted electronically (Appendix A, Article 17(3) and (4)). We have found no decision by the EU and Morocco to use the EU’s Registered Exporter system (REX) for their bilateral trade. Proof of origin between them therefore remains the EUR.1 or the origin declaration.
Diagonal cumulation. Materials originating in another "applying Contracting Party" may be used without having been sufficiently worked, provided the processing in the exporting country goes beyond the minimal operations listed in Article 6 (Appendix A, Article 7(1)). If it does not, the product takes the origin of the party that supplied the highest value of originating materials, unless the value added locally is greater (Article 7(2)).
Full cumulation. Working or processing carried out in another applying party counts as carried out in the exporting country when the products are processed further there, except for textiles of HS Chapters 50 to 63 (Article 7(3)). For those chapters, full cumulation applies only to processing in the importing party, in bilateral trade (Article 7(4)).
Conditions. A preferential trade agreement in accordance with GATT Article XXIV must be applicable between the parties involved in acquiring the originating status and the party of destination, and the materials must have obtained origin under identical rules (Article 8(1)). Cumulation with a given partner applies only from the date given in notices published in the Official Journal of the EU (C series) and in an official publication in Morocco (Article 8(3)). Where cumulation was used, the proof of origin should state "CUMULATION APPLIED WITH" followed by the partner’s name, in Box 7 for a EUR.1 (Article 8(4)).
Supplier’s declarations. Where goods processed in another applying party without acquiring origin are used under full cumulation, the supplier’s declaration is the evidence of that processing (Article 29(1) and (2)). It is made out per consignment, or as a long-term declaration for regular supplies (Article 29(3) and (4); Annexes VI and VII).
No-drawback rule. Under the transitional rules, the ban on duty drawback or exemption for non-originating materials applies only to products of HS Chapters 50 to 63 (Appendix A, Article 16(1)). It does not apply to bilateral EU–Morocco trade without cumulation with materials from a third partner (Article 16(5)), nor to cumulation under Article 7(4) or (5) (Article 16(4)). Where it applies, the exporter must be able to prove that no drawback was obtained (Article 16(3)).
The customs of the importing country may request a subsequent verification at random, or when they have reasonable doubts about the authenticity of the document, the origin of the goods or compliance with the rules (Appendix A, Article 34(1)). The check is carried out by the customs of the exporting country, which may call for any evidence and inspect the exporter’s accounts (Article 34(3)). While it is under way, the importing customs may suspend the preference, in which case the goods are released to the importer subject to any precautionary measures they consider necessary (Article 34(4)).
If, in a case of reasonable doubt, there is no reply within ten months of the request, or the reply does not establish authenticity or origin, the importing customs refuse the preference except in exceptional circumstances (Article 34(6)). In practice the importer then pays the full duty, although it usually has no access to the exporter’s files. That is why importers should have a contractual right to obtain the supporting documents from the supplier.
Record-keeping. The exporter keeps a copy of each proof of origin and all supporting documents for at least three years; the supplier keeps its supplier’s declarations for the same period (Appendix A, Article 31(1) and (2)). The issuing customs keep the EUR.1 application form, and the importing customs keep the proofs submitted to them, for at least three years (Article 31(4) and (5)).
Consequences. Each party must provide for criminal, civil or administrative penalties for breaches of its national legislation related to the origin rules (Appendix A, Article 36). In the EU, duty on goods wrongly entered at the preferential rate is recovered under the Union Customs Code. The customs debt may be notified within three years from the date it was incurred, extended to between five and ten years where the act was liable to give rise to criminal proceedings (Regulation (EU) No 952/2013, Article 103(1) and (2)). Where a wrong preferential origin results from an error by the authorities of the exporting country, the importer may obtain remission only if it acted in good faith and the conditions of Article 119(3) of the Code are met. In Morocco, recovery and penalties fall under the Code des douanes et impôts indirects.
Minor discrepancies between the proof and the import documents do not by themselves void the proof if it clearly corresponds to the goods, and obvious formal errors such as typing errors do not lead to rejection unless they cast doubt on the content (Appendix A, Article 28).
This article sets out the law in force on 2 October 2026. It is not legal advice.
A note on how this works in practice. Origin disputes are rarely about the rule itself. They turn on whether the exporter can produce the costing, the supplier’s declarations and the bill of materials years after the shipment, often for an importer it no longer works with. Setting up that file and the contractual right to it before the first shipment is far cheaper than reconstructing it during a verification.
