European importers of grain-oriented silicon magnetic steel (GO-GOES) face an immediate additional cost in their purchases: the European Commission has activated a provisional safeguard measure through Commission Implementing Regulation (EU) 2026/2133, published and in force since 18 September 2026.
The trigger is a significant increase in imports of this material which, according to the Commission's investigation, threatens to cause serious injury to the European steel industry. GO-GOES is a critical input for the manufacture of high-efficiency electrical transformers, making this measure an urgent matter for the entire value chain of the electrical sector.
What does this regulation establish?
Regulation 2026/2133 imposes additional provisional tariffs on imports of flat-rolled products of grain-oriented silicon magnetic steel (GO-GOES) into the European Union. This is a commercial safeguard measure, an instrument that the EU activates when it detects that the volume of imports of a product threatens to seriously damage equivalent European producers.
| Element | Detail |
|---|---|
| Affected product | Grain-oriented silicon magnetic steel (GO-GOES), in the form of flat-rolled products |
| Main use of the product | Manufacture of high-efficiency electrical transformers |
| Type of measure | Additional provisional tariff (safeguard) |
| Reason for the measure | Significant increase in imports with risk of serious injury to European industry |
| Nature of the measure | Provisional — may be modified or confirmed following definitive investigation |
| Legal basis | Commission Implementing Regulation (EU) 2026/2133, of 18 September 2026 |
Being a provisional measure, the Commission will continue the investigation and may confirm, modify or lift it in its definitive decision. However, the tariffs are enforceable from the first day of entry into force, so there is no point in waiting for the final decision to act.
Economic and operational impact
The direct effect is an increase in procurement costs for any company that imports GO-GOES from outside the EU. This tariff surcharge is not optional or deferrable: it applies at the moment of customs clearance.
The cascading consequences affect the entire value chain:
- Direct importers: pay the additional tariff at customs, which reduces their margin or forces them to pass the cost on to the customer.
- Transformer manufacturers: their main raw material increases in price, compressing production margins or forcing price revisions to customers.
- Electrical infrastructure projects: budgets for transformers for electrical networks, renewables or industry may be impacted upwards.
- Ongoing contracts: supply contracts signed before 18 September 2026 without a price revision clause may generate losses if they do not account for this surcharge.
Given that the measure is provisional, there is also a risk of planning uncertainty: companies do not yet know whether the definitive tariff will be equal, higher or lower. This complicates the signing of new long-term contracts and the preparation of budgets for 2027.
Who does it affect?
- Importers of GO-GOES magnetic steel in any EU Member State, regardless of the country of origin of the import.
- Manufacturers of electrical transformers that use GO-GOES as their main raw material.
- Manufacturers of electrical equipment that incorporate transformers or magnetic cores in their products.
- Distributors and traders of special steel operating in the European market.
- Procurement and supply chain departments of industrial companies with exposure to this material.
- CFOs and controllers of companies with GO-GOES supply contracts in force or under negotiation.
Practical example
A Spanish manufacturer of distribution transformers regularly purchases 500 tonnes per year of GO-GOES steel imported from outside the EU for its production line. Until 17 September 2026, this procurement was not subject to safeguard tariffs.
From 18 September 2026, each tonne imported carries an additional provisional tariff that increases the purchase cost. If that manufacturer has supply contracts signed with end customers (utilities, construction companies, industry) at a fixed price and without a price revision clause, it absorbs the tariff surcharge entirely in its margin.
Additionally, if it has orders in transit or in a foreign supplier's warehouse pending customs clearance, it must verify whether those operations are subject to the new tariff depending on the date of customs declaration. The immediate review of contracts and ongoing operations is, in this scenario, a financial priority.
What should companies do now?
- Audit GO-GOES supply contracts in force: identify whether they include price revision clauses for tariff changes or whether the surcharge falls on the buyer or seller.
- Review operations in transit: check whether there are imports pending customs clearance that will be subject to the new provisional tariff from 18 September 2026.
- Quantify the impact on margins: calculate the tariff surcharge on the annual import volume to assess the impact on the income statement.
- Review selling prices and customer budgets: if the surcharge cannot be absorbed in margin, initiate negotiations with customers to pass on the increase, especially in new contracts or renewals.
- Explore alternative sourcing: evaluate whether there are GO-GOES suppliers within the EU or in countries with trade agreements that are not subject to the safeguard.
- Monitor the definitive investigation: the measure is provisional and may change. Designate a person responsible for regulatory monitoring to act as soon as the final decision is published.
- Consult with a foreign trade specialist: to determine exactly which NC codes and operations are affected and whether there is any exemption mechanism or applicable quota.
Frequently asked questions
From when does the provisional tariff on GO-GOES magnetic steel apply?
The additional provisional tariff is enforceable from 18 September 2026, the date of publication and entry into force of Commission Implementing Regulation (EU) 2026/2133. There is no grace period: imports cleared through customs from that date are subject to the measure.
What exactly is GO-GOES steel and why is it so important for transformers?
GO-GOES (grain-oriented silicon magnetic steel) is a special flat-rolled steel with directional magnetic properties that make it essential for the cores of high-efficiency electrical transformers. It is a material with no direct substitute in many applications, which means that the price increase due to tariffs cannot be easily avoided by changing materials.
Is the measure definitive or can it change?
The measure is provisional, as expressly established by Regulation 2026/2133. The European Commission will continue the investigation and publish a definitive decision that may confirm, modify or lift the tariff. However, while the provisional measure is in force, the tariff is enforceable and cannot be ignored while waiting for the final decision.
Does this measure affect only imports from certain countries or all GO-GOES imports?
Regulation 2026/2133 establishes the measure on GO-GOES imports in general, in response to the significant increase in imports that threatens European industry. To find out whether there are exclusions by country of origin or specific quotas, it is necessary to consult the full text of the regulation in the Official Journal of the EU.
What should I do if I have GO-GOES supply contracts signed before 18 September 2026?
The first thing is to review whether the contract includes price revision clauses for tariff or regulatory changes. If it does not, the surcharge may fall on your company. In that case, you should quantify the impact, consider renegotiating with the supplier or customer, and consider seeking specialized foreign trade legal advice to evaluate options.
