From 1 October every steel import into the European Union must be traced back to the furnace where it was first cast. Importers who cannot evidence the country of melt and pour face rejection at the border, and the data will govern quota allocation from 2027.
BRUSSELS / LONDON, 22 September 2026
In nine days the European Union will begin requiring importers of steel to declare and evidence the country in which their steel was melted and poured, a traceability obligation that reaches behind the country of export and behind the non-preferential rules of origin to the furnace where the metal was first produced in liquid form.
The requirement takes effect on 1 October 2026 under Commission Implementing Regulation (EU) 2026/1963, adopted on 28 August 2026. It gives operational shape to one of the most consequential and least understood provisions of Regulation (EU) 2026/1384, the Steel Regulation that replaced the European Union’s expiring steel safeguard and entered into force on 25 June 2026.
Analysis published this week by Baker McKenzie’s trade and customs team in London, written by Jennifer Revis and Alexandra Lambert, sets out what the evidentiary framework requires and warns that importers without adequate proof face outright rejection of their consignments.
A permanent instrument, not a rolled-over emergency measure
The melt and pour obligation cannot be understood in isolation from the regime it sits within, and the nature of that regime has changed fundamentally.
The safeguard measures in place from January 2019 were a temporary instrument, introduced in response to an emergency surge of steel imports and extended twice before expiring on 30 June 2026. The Steel Regulation that replaced them is something different. Adopted on 17 June 2026 from the Commission proposal designated COM(2025)726, it delivers on the EU Steel and Metals Action Plan published in March 2025 and is designed as a permanent, structural commercial policy instrument addressing the long-term effects of global overcapacity on the European market.
That distinction has practical consequences. A temporary safeguard is something importers wait out. A permanent instrument is something they restructure around.
The core parameters of the new regime are severe by historical standards. Tariff-free import volumes have been cut substantially, by roughly 47 per cent against the previous quota levels, and the out-of-quota duty has been doubled to 50 per cent ad valorem. The product scope is organised into 30 separate quotas. The tariff rate quota system and the 50 per cent out-of-quota duty have applied since 1 July 2026.
The melt and pour obligation is the next phase of that architecture, and it arrives on 1 October.
What melt and pour means
The country of melt and pour is defined as the location where raw steel or iron is first produced in liquid form in a furnace and then cast into its initial solid state. It is a concept aimed at tracing steel back to its true point of production rather than merely its country of export or the country where it last underwent a substantial transformation.
The distinction from non-preferential origin is the point. Under standard origin rules, steel that is melted and cast in one country and then rolled, coated or otherwise processed in another may acquire the origin of the processing country. That treatment has long been used, legitimately and otherwise, to route material through intermediate jurisdictions and access quota allocations that would not be available to the material’s actual producer.
Melt and pour closes that route by recording the furnace, regardless of what happens afterward.
Three phases, not one
The Baker McKenzie analysis emphasises that the requirement should be read as a deliberate three-stage trajectory rather than a single change.
In the first phase, beginning 1 October 2026, melt and pour operates purely as a transparency and traceability obligation. Importers must identify and evidence the country of melt and pour, but that information does not condition access to the tariff rate quotas. Quota access continues to be governed by the non-preferential origin of the goods. The Commission is, in effect, building a dataset.
In the second phase, from 1 October 2027, the country of melt and pour becomes one of the criteria the Commission takes into account when distributing quotas among supplying countries. At that point the data acquires commercial consequence: a country whose recorded melt and pour volumes diverge sharply from its recorded export origin volumes will find that divergence reflected in its allocation.
In a possible third phase, the Steel Regulation leaves open the prospect that melt and pour becomes the actual basis on which imports qualify for a quota at all. The Commission is required to assess that question and may propose legislation to that effect in due course.
Importers who treat the October obligation as a documentary formality are therefore misreading it. It is the first step in a transition from origin-based to production-based quota administration, and the data being collected from October will shape allocations a year later.
The evidence framework
Implementing Regulation 2026/1963 establishes an evidentiary structure resting on three pillars.
The primary form of evidence is the Mill Test Certificate. At the moment of import, importers of products falling within Annex I to the Steel Regulation must provide an MTC identifying both the country of melt and pour and the heat number of the imported steel. The heat number is the identifier assigned to a specific batch of molten steel produced in a single furnace run, and it is the link that ties a finished product back to its casting.
Where an MTC is provided but is silent on either the country of melt and pour or the heat number, customs authorities may accept a defined and limited set of alternative documents to complete the picture. These include invoices, delivery notes, quality certificates, purchase orders or contracts, and long-term supplier declarations, provided they establish both required data points. Cost-accounting and production records, customs documents from the exporting country, commercial correspondence and descriptions of the production process may also be considered as supplementary evidence.
A transitional year allows for more flexibility than the regime will ultimately permit. Between 1 October 2026 and 30 September 2027, the alternative documents may stand on their own, without an MTC, provided they establish both required data points. From 1 October 2027 onward, an MTC becomes compulsory, and the other documents will be accepted only as a supplement to it.
Customs authorities retain the ability to verify whatever evidence is submitted. Importers should be aware, the Baker McKenzie analysis notes, that an import lacking adequate proof of the country of melt and pour is liable to be rejected outright.
That last point is the one that should concentrate attention. This is not a penalty regime in which an importer pays a fine and the goods clear. It is a condition of admissibility.
The compliance burden falls on the supply chain
The practical difficulty with melt and pour is that the importer is required to evidence a fact about a transaction several steps upstream of its own purchase.
An importer buying coated coil from a European stockholder who bought from a Turkish re-roller who bought hot-rolled coil from a trader who bought from a mill in a third country has to document the furnace at the far end of that chain. In many steel trading chains, the MTC travels with the material as a matter of ordinary commercial practice. In others, particularly where material has been cut, slit, re-coiled or blended, the link between the physical product and its original heat number has been broken.
The transitional year to 30 September 2027 exists precisely to allow those links to be rebuilt. Importers who use it to renegotiate supplier documentation obligations, to require MTCs as a condition of purchase, and to establish internal systems that retain heat number data through processing steps will arrive at the compulsory MTC deadline in reasonable shape. Importers who do not will find, from October 2027, that a material share of their supply base cannot produce a compliant document.
The Baker McKenzie authors make a useful observation on this point. The melt and pour concept closely mirrors the origin-tracing obligation that steel importers will already be familiar with under the European Union’s restrictive measures on Russian iron and steel, where Mill Test Certificates, supplemented as needed by other documentation, have been used to evidence the origin of steel inputs. Given the substantial overlap in product coverage, businesses that have already built compliance processes for those sanctions requirements should be well placed to extend them rather than starting from scratch.
That is genuinely good news for the larger importers, most of whom built such processes in 2023 and 2024. It is less helpful for smaller importers and for downstream manufacturers who buy steel as an input rather than as a traded commodity, and who may never have engaged with the sanctions-driven documentation regime at all.
The scope is not fixed
A further point deserves attention from any business that imports steel products currently outside the regime.
The Commission has launched a targeted stakeholder consultation on the first review of the Steel Regulation’s product scope, open until 30 September 2026. The review examines whether a number of additional product groups, identified by Combined Nomenclature code, should be brought within the regime. The categories under consideration are tubes, pipes and hollow profiles of cast iron; non-alloy and other alloy wire; stainless wire; and non-alloy and other alloy forged bars.
Based on the responses received, the Commission is due to finalise its assessment by 31 December 2026 and may, where warranted, propose an extension of scope. If the scope is extended, both the tariff rate quota obligations and the melt and pour evidentiary requirements would follow for the newly covered products.
For businesses importing wire, forged bars or cast iron tube and pipe, the consultation window closes in eight days. It is the last opportunity to put a position on the record before a decision that would bring those products within a regime carrying a 50 per cent out-of-quota duty.
Economic impact
The economic effect of the melt and pour requirement operates through three distinct channels, and only one of them is a direct cost.
The direct compliance cost is real but bounded. Obtaining, checking, retaining and presenting Mill Test Certificates imposes administrative burden, requires system changes and creates a new category of customs risk. For a large importer with mature documentation processes, the incremental cost is modest. For a mid-sized importer handling many small consignments from diverse suppliers, it is not.
The second channel is trade diversion within the supply chain. Suppliers who cannot produce compliant documentation become commercially unviable for the European market, regardless of their price or quality. That advantages integrated mills that control their own casting and can issue MTCs as a matter of course, and disadvantages traders, re-rollers and processors whose value proposition rests on sourcing flexibility. Over the transitional year, expect European buyers to consolidate their supply bases around suppliers who can document reliably.
The third channel, and the largest over time, is the quota reallocation that begins in October 2027. Once melt and pour data informs country allocations, the quota shares of countries that function principally as processing or transshipment points for steel cast elsewhere are likely to fall, and the shares of countries that actually cast steel are likely to rise. That is the policy intent. For importers whose sourcing strategy depends on quota availability from a particular origin, it is a material planning risk that should be modelled now rather than discovered in late 2027.
What importers should do before 1 October
The immediate checklist is short and specific.
Map the melt and pour country for every steel product currently imported, working back through the supply chain as far as necessary. Where the answer is unknown, that is itself the finding.
Confirm with each supplier that they can provide a Mill Test Certificate stating both the country of melt and pour and the heat number. Where they cannot, establish which of the permitted alternative documents they can provide, and document that arrangement contractually rather than by correspondence.
Check whether internal systems retain heat number data through processing, storage and re-invoicing. Many enterprise resource planning configurations discard it, which makes reconstruction after the fact expensive.
Use the transitional year deliberately. The window to 30 September 2027 during which alternative documents may stand alone is the only period in which supply chains can be remediated without immediate customs consequence. It should be treated as a project with a deadline, not as a grace period.
Review the product scope consultation before it closes on 30 September if any imported line falls within the four categories under review.
The larger shift
Taken together with the tariff rate quota cuts, the 50 per cent out-of-quota duty and the parallel safeguard measures now applied to grain-oriented electrical steel, the melt and pour requirement marks the completion of a European steel trade policy that is no longer reactive.
The 2019 safeguard was a response to a specific event. The 2026 Steel Regulation is an assertion that global steel overcapacity is a permanent structural condition requiring a permanent structural answer, and that the European Union intends to administer access to its market on the basis of where steel is actually made rather than where it was last handled.
For importers, the strategic implication is that supply chain opacity has become expensive. For a generation, the ability to source flexibly through intermediate markets was a competitive advantage in steel trading. Under the regime taking shape from 1 October, it is a liability.
Who is most exposed
The burden of the new requirement is not distributed evenly, and it is worth identifying where it lands hardest.
Integrated mills exporting directly to European customers are least affected. They cast their own steel, they issue Mill Test Certificates as a matter of routine, and the country of melt and pour is trivially identifiable. For these suppliers the requirement is a documentation formality.
Re-rollers and processors are in a more difficult position. A mill that buys semi-finished steel, hot-rolled coil or slab from another producer and processes it into a finished product must obtain and pass on the melt and pour data of its own supplier. Where that supplier is itself a trader, or where the semi-finished material has been purchased on the spot market from multiple sources, reconstructing the chain is genuinely difficult. These operators face the sharpest adjustment.
Traders and stockholders face a distinct version of the same problem. Their commercial model rests on aggregating material from multiple sources, holding inventory and supplying it in configurations the buyer wants. That model tends to break the link between a physical item in a warehouse and the certificate that accompanied it on arrival. Stockholders who have not implemented heat number tracking through their inventory systems will find that material in stock on 1 October may not be documentable when sold.
Downstream manufacturers who import steel components rather than steel products should check the Annex I product scope carefully. Many will find they are outside the regime entirely. Those inside it are often the least prepared, because they have never treated steel documentation as a compliance matter.
Finally, importers of products from countries that function principally as processing hubs face a specific strategic risk. Their current quota access rests on non-preferential origin, which may be acquired through processing. From October 2027, when melt and pour begins to inform quota distribution, the allocations available from those origins may contract sharply. That is a sourcing risk with a known date attached, which makes it unusually manageable if addressed in time.
Interaction with other measures
The melt and pour requirement does not operate alone, and its interaction with adjacent regimes creates both efficiency and complexity.
The closest parallel is the European Union’s restrictive measures on Russian iron and steel, which have required importers to evidence that steel inputs did not originate in Russia. That regime established Mill Test Certificates as the standard evidentiary instrument and forced a generation of importers to build supplier documentation processes. The overlap in product coverage is substantial, and importers who complied with the sanctions regime have most of the infrastructure they need.
The Carbon Border Adjustment Mechanism creates a second overlap. CBAM reporting requires importers of covered goods, which include iron and steel, to report embedded emissions, and from the definitive period to surrender certificates covering them. The data required for CBAM includes the identity of the installation where the goods were produced, which is closely related to, though not identical with, the country of melt and pour. Importers building data collection systems for one requirement should build them to serve both.
The third interaction is with the tariff rate quota system itself. Quota access currently depends on non-preferential origin. From 1 October 2027 melt and pour becomes an input to quota distribution among countries. That means importers will, for a period, be operating under two overlapping geographic concepts applied to the same consignment for different purposes. The scope for confusion and for classification error is considerable, and customs authorities across 27 member states will be applying the rules with varying levels of consistency in the early period.
A note on enforcement
The Implementing Regulation gives customs authorities verification powers, and the consequence of inadequate proof is rejection of the import. That is a severe remedy, and its practical application will vary.
In the early months, a degree of administrative tolerance is likely as customs authorities and importers adjust. Experience with previous EU customs and trade measures suggests that enforcement intensity rises after the first six to twelve months, often following a coordinated verification exercise that identifies systematic non-compliance in a particular sector or trade lane.
Importers should not plan around early leniency. The transitional flexibility written into the regulation, permitting alternative documents to stand alone until 30 September 2027, is the tolerance the legislator intended. It is explicit, time-limited, and clearly signalled. Reliance on additional informal tolerance beyond that is not a compliance strategy.
