For a long time, proof of preferential origin took a familiar form: a paper document, endorsed by the customs authority, complete with its boxes, signatures, and stamps—and, in case of any issues, duplicates that were more or less easy to obtain.
That world hasn't completely disappeared, but it is living out its final hours.
Above all, we must not misunderstand what is changing: the digitization of proof of origin is not simply a matter of replacing a paper document with a PDF. It changes the way in which tariff preferences are proven, verified, and ultimately administered
Rules of origin and proof of origin: two distinct topics
The first point to keep in mind is simple, but by no means insignificant: tariff preferences are always based on two distinct factors.
On the one hand, there is the rule of origin—that is, what actually qualifies a product as originating under the proposed free trade agreement.
On the other hand, there is proof of origin—in other words, the documentation that the importer submits or declares in order to qualify for preferential import tariffs.
This distinction may seem theoretical; in reality, it is central to the issue. It is possible to have an originating product without being able to provide admissible proof of its origin. Conversely, it is entirely possible to produce a document that is formally correct even though the determination of origin upstream is incorrect.
How preference is demonstrated today
In practice, there are three main categories of evidence.
The first is an authority-certified certificate, typically an EUR1 or an EUR-MED.
The second option is a declaration on a commercial document, often in the form of a declaration of origin or a certificate of origin issued by the exporter.
The latest, introduced more recently in free trade agreements, is the “importer’s knowledge” approach, under which the importer claims preferential treatment because they are able to demonstrate on their own that the conditions for preferential origin are met.
In addition, there is a distinction between different types of exporters: authorized exporters on one hand, and registered exporters on the other. Digitalization does not replace these categories; rather, it enables them to evolve by placing even greater emphasis on ease of management and traceability.
Why this change?
Officially, and quite logically, to improve reliability, speed, and automation. A paper document can be filled out incorrectly, contain inconsistencies, be lost, damaged, or tampered with. Structured data, on the other hand, can be verified more quickly, compared with other reported information, and shared more easily between government agencies.
This is where things get interesting: in a paper-based environment, the focus is primarily on verifying a document. In a digital environment, the focus is on verifying both the document AND the data associated with it. The verification process no longer focuses solely on the presence of a stamp, but on the consistency of a set of information.
From document to data
Digitization does not merely change the format of the proof of origin; it also changes the way it is secured and verified.
Whereas paper documents focused on the original document, the stamp, or the signature, digital systems place a central emphasis on data quality, traceability, and secure transmission.
For operators, this means paying closer attention to the quality of the information provided.
Less paper doesn’t mean less work at the source. Quite the contrary: it requires greater internal discipline, more authorizations, more data quality control, and often a greater ability to justify—sometimes very quickly—what has been reported.
Three models, three approaches
We can, quite clearly, distinguish three models.
- Paper documents. This is the traditional model for certified documents, in which the physical paper original is the only version that is circulated and considered authentic.
Its advantage is clear: it is time-tested, familiar, and reassuring. Its disadvantage is just as clear: it is slow, formal, and prone to errors in data entry and document loss.
In many settings, paper remains psychologically powerful but operationally fragile.
- The second model is a data-driven paper.
The perfect example of this compromise is the EODES system established under the free trade agreement between Switzerland and China. Under this arrangement, the EUR1 form remains in use, but the authorities also exchange data extracted from the form.
The benefit is real, because the operator can stick with the process they’re familiar with, while enjoying more automated control and less reliance on physical paper flow.
But this solution remains a hybrid: it improves the old system without completely replacing it. And like all hybrid models, it sometimes combines the drawbacks of both approaches.
- Finally, the third model involves digital proof embedded in the commercial document, a feature that is now common in recent agreements.
Here, proof is circulated almost exclusively in digital form. This is the case for many declarations or certificates of origin used in agreements such as CETA, JEFTA, or the agreement with South Korea.
The improvement in fluidity is obvious, but it requires a high level of documentary maturity.
When the proof of origin is included in the invoice or another commercial document, data quality becomes critical. There is no longer any room for “correction” through a stamped paper copy: if the declaration is mishandled, the error is immediate and obvious.
Toward more structured evidence
And then there is a more ambitious goal: that of highly structured electronic certificates, potentially backed by distributed ledger technologies.
Here again, we must avoid oversimplifying the issue. While these tools can ensure the secure issuance, transmission, and verification of the authenticity of proof of origin, they do not, on their own, prove that the origin has been correctly determined.
In other words, the technical robustness of the platform does not replace the soundness of the original analysis.
Initiatives already exist, but they do not all follow the same logic. In ASEAN, the Single Window already enables the electronic exchange of Form D certificates of origin between administrations, with full implementation of e-Form D scheduled for 2024. On the pan-European front, the European Union is moving forward with the e-PoC project, following a phased timeline that is expected to lead to full-scale implementation starting at the end of the decade.
The process is well underway, but we have not yet arrived at a single, fully harmonized, and widely adopted model.
The real issue: the method
Ultimately, the real issue is less about technology than about methodology.
Digitization rewards operators who can document and manage their supply chain.
Those who continue to treat proof of origin as a purely administrative exercise may find themselves more vulnerable tomorrow than they were yesterday. Why? Because the more automated the verification process becomes, the faster inconsistencies come to light.
Customs data leaves no room for error once it begins to be systematically compared.
The last word
It boils down to a simple idea: proof of origin doesn’t disappear; it simply changes in nature.
We are shifting from a document-based approach to a data-based approach, without compromising the rigor required for the source material itself.
For businesses, the challenge is therefore not simply to “go digital.” The challenge is to understand that, in international trade, digitization does not automatically simplify compliance; rather, it makes compliance more visible, faster, and often more demanding.
