| Category | European Regulation — Foreign Trade / Anti-dumping |

| Product origin | People's Republic of China |
| Measure | Mandatory registration of imports (precautionary measure prior to possible retroactive anti-dumping or countervailing duties) |
If your company imports silicon from China, every kilogram entering the EU from October 23, 2026 is registered. It is not a minor bureaucratic procedure: it is a signal that the European Commission is building the case to potentially impose anti-dumping or countervailing tariffs on those same imports with retroactive effect.
The Commission Implementing Regulation (EU) 2026/2346, published in the Official Journal on October 26, 2026, activates this precautionary mechanism. Its objective is for the Commission to have precise data on import volumes and prices during the investigation period, so that if definitive measures are imposed, they can be applied to operations already registered.
What does this regulation establish?
Regulation 2026/2346 subjects all imports of silicon originating from the People's Republic of China to mandatory registration. This is a standard precautionary measure in EU anti-dumping and anti-subsidy procedures, which operates in two phases:
- Registration phase (active from 23/10/2026): Importers must declare each shipment to national customs authorities. The Commission collects data on volumes and prices.
- Resolution phase (future): If the investigation concludes with definitive measures, anti-dumping or countervailing duties may be applied retroactively to imports already registered during the previous phase.
This mechanism reflects the EU's growing trade pressure on strategic Chinese products. Silicon is a critical input for the energy transition and the technology industry, making it a priority target of European trade policy.
| Element | Detail |
|---|---|
| Affected product | Silicon originating from the People's Republic of China |
| Type of measure | Mandatory registration of imports (precautionary measure) |
| Objective of the measure | Collect data on volumes and prices for possible retroactive duties |
| Possible future duties | Anti-dumping and/or countervailing (anti-subsidy) |
| Importer obligation | Declare each shipment to national customs authorities |
| Retroactive effect | Yes, if the investigation concludes with definitive measures |
Economic and operational impact
The immediate impact is operational: new declaration burden on each import. But the real economic risk is the potential for retroactive tariffs. This means that companies continuing to import Chinese silicon during the investigation period are accumulating an unquantified financial contingency on their balance sheets.
The most relevant practical consequences are:
- Risk of deferred cost: Anti-dumping or countervailing duties imposed in the future could be applied to imports already made and registered, generating unexpected customs debt.
- Urgent review of supply contracts: Contracts signed without tariff risk clauses expose the importer to absorbing the entire cost of possible future duties.
- Pressure on margins: Silicon-intensive sectors (photovoltaic, semiconductors, metallurgy, chemicals) will see their cost planning compromised while the investigation lasts.
- Need for supplier diversification: Regulatory uncertainty incentivizes seeking alternative sources of silicon outside China to reduce exposure.
Who does it affect?
- European importers of silicon of any form or purity originating from China.
- Photovoltaic industry (solar energy): Silicon is the main component of solar panels. Companies manufacturing or installing solar cells or silicon ingots from China are directly exposed.
- Semiconductor manufacturers: High-purity silicon is a critical input for chips and electronic components.
- Metallurgical sector: Metallic silicon is used in aluminum and steel alloys.
- Chemical industry: Silicon is the basis of silicones and other industrial compounds.
- Customs agents and logistics operators managing these shipments on behalf of their clients.
Practical example
A Spanish photovoltaic module manufacturer imports 500 tons of Chinese polycrystalline silicon per month for its production line. From October 23, 2026, each of those shipments is registered in customs.
If the Commission's investigation concludes in, for example, six months with the imposition of a definitive anti-dumping duty, that duty could be applied retroactively to the 3,000 tons imported during the registration period. Without a tariff risk clause in its contract with the Chinese supplier, the company would absorb that additional cost entirely.
Recommended immediate action: review the supply contract and introduce a clause that passes on to the supplier, in whole or in part, any retroactive tariff duty imposed as a result of the ongoing investigation.
What should companies do now?
- Identify if you import silicon of Chinese origin: Review your supply chain. The origin declared in customs is what determines if registration applies. If your supplier is European but the silicon comes from China, the origin is still Chinese.
- Review and update supply contracts: Incorporate tariff risk clauses that allow you to pass on to the supplier any retroactive duties that may be imposed. This is the most urgent action with the greatest economic impact.
- Coordinate with your customs agent: Ensure that each shipment of Chinese silicon is correctly declared under the new registration regime. An error in the declaration can complicate matters in the event of eventual retroactive settlement.
- Quantify the financial contingency: Calculate the volume of Chinese silicon you expect to import during the investigation period and estimate the potential impact based on possible tariff rates. Provision if your accounting policy requires it.
- Explore alternative supply sources: Evaluate silicon suppliers in other countries (Norway, Brazil, USA) to reduce dependence on China and exposure to tariff risk.
- Follow the progress of the investigation: The Commission will publish updates on the procedure in the EU Official Journal. Any change in the investigation status may affect your purchasing strategy.
Frequently asked questions
What does it mean that my Chinese silicon imports are "registered"?
It means that each shipment of silicon originating from China entering the EU from October 23, 2026 must be declared to national customs authorities. The European Commission uses that data (volumes and prices) for the ongoing anti-dumping or anti-subsidy investigation. If the investigation concludes with definitive measures, duties may be applied retroactively to those already registered imports.
Do I have to pay additional tariffs right now for importing Chinese silicon?
Not immediately. Regulation 2026/2346 only imposes mandatory registration, not payment of duties. The risk is future and retroactive: if the Commission imposes definitive anti-dumping or countervailing duties, they could be applied to imports registered from October 23, 2026. That is why it is critical to act now on contracts and financial planning.
Which sectors are most exposed to tariff risk from this measure?
The four sectors identified in the Regulation are: photovoltaic industry (solar energy), semiconductor manufacturers, metallurgical sector and chemical industry. All of them are intensive users of silicon as a productive input and depend to varying degrees on Chinese supply.
What clause should I include in my silicon supply contracts?
Regulation 2026/2346 does not specify contract content, but the operational recommendation derived from the regulation is to incorporate a tariff risk clause that allows you to pass on to the Chinese supplier, in whole or in part, any anti-dumping or countervailing duty imposed retroactively as a result of the ongoing investigation. Consult a specialist in international trade to draft this clause effectively.
When did the mandatory registration of Chinese silicon come into force?
From October 23, 2026, the date of entry into force of Commission Implementing Regulation (EU) 2026/2346. Publication in the Official Journal occurred on October 26, 2026, but the regulation has effect from three days earlier.
