data while superseding the previous document. No single operator- and no single certificate- holds the complete, continuous chain linking the finished product to the original melt. By the time the tubes reach the EU border, no simple quantitative or physical correspondence exists between the original melt certificate and the specific lot of goods presented to customs. There is no laboratory method capable of identifying the country in which steel was melted. The melting stage leaves no chemical marker, no structural signature, no metallurgical fingerprint. The product itself does not reveal its birthplace. At this point, the system rests entirely on documentary trust.
No verifiable documentary link Under CBAM, verification concerns data whose accuracy can be independently assessed: the documentation serves to compile information that is measurable, auditable, and objectively verifiable. Under a melt-and-pour rule, by contrast, the decisive issue becomes the authenticity of the documentary link between a specific lot of goods and a declared melt origin- a link that cannot be physically demonstrated. When tariff treatment or quota access depends on that link, significant financial consequences attach to a criterion resting solely on documentary continuity- and ultimately on documentary trust. The higher the stakes, the more fragile that foundation becomes. If a verifier with full on-site access cannot physically reconstruct melt origin with certainty, it is difficult to see how a customs authority operating at a distance could do so on the basis of documents alone. The customs officer is aware of the economic reality within which trade operates and recognises that both exporter and importer have a legitimate commercial interest in a declaration that secures the most favourable treatment available under the law- the exporter to remain competitive in the EU market, the importer to avoid substantial additional duties. Precisely because significant financial consequences may depend on a single certificate, such documents inevitably attract heightened scrutiny. A certificate can be substituted and, in an increasingly digital environment, amended or even falsified with relative ease. Where verification rests exclusively on documentary continuity, the system depends not on demonstrable material evidence but on the trust placed in the integrity of the documentation chain. The practical consequence would be a shift of decision-making power from Brussels to the 27 national customs administrations responsible for applying the rule. Each operates within its own legal culture and administrative environment. Customs duties form part of the EU’ s own resources, but Member States retain 25 % as collection costs. In Member States hosting major seaports, where very large volumes are cleared, these retained amounts constitute a meaningful component of public revenue. Faced with high financial stakes, customs authorities would inevitably scrutinise documentation differently, reflecting differences in administrative culture, enforcement priorities, resource constraints and the significant role that retained customs revenues play in national budgets. Some may accept certificates at face value. Others may require extensive supplementary evidence. Divergent interpretations could emerge. Identical consignments might be treated differently depending on the Member State of importation.
Potential fragmentation What was conceived as a harmonised Union rule could, in practice, fragment into 27 enforcement approaches. Disputes would follow. Litigation before national courts— and ultimately before the Court of Justice— would be likely.
“ Transparency is one thing. Origin determination is another”
– Christophe Lagrange, EURANIMI
None of this implies that enhanced traceability is undesirable. Greater transparency regarding primary steel inputs may well contribute to improved monitoring of trade flows and supplychain resilience. A melt-and-pour reporting requirement, if conceived strictly as a transparency tool without fiscal, quota-related, or origin-determining consequences, would not raise structural difficulties. In such a framework, operators would have little incentive to contest or obscure information. The difficulty arises only if melt-stage origin becomes determinative for tariff treatment, quota allocation, or the attribution of non-preferential origin. In that case, significant financial and legal consequences would attach to a criterion that cannot be physically verified and that rests exclusively on documentary continuity. That is where legal uncertainty begins. The current Union Customs Code framework, attributing origin on the basis of the last substantial transformation, offers clarity and operational predictability. Replacing or displacing that logic with a melt-stage criterion would fundamentally alter the structure of origin determination. If melt-and-pour traceability is to be introduced, clarity about its legal function is therefore essential. Transparency is one thing. Origin determination is another.
