Cancellation of Nordkalk QL 0-2 Biocide: What Manufacturers and Users Must Do in the EU

Key data

Manufacturers, distributors and industrial users of the Nordkalk QL 0-2 biocide face an immediate obligation: the product no longer has valid authorization in the European Union. The Implementing Regulation (EU) 2026/2199, published on October 5, 2026 and effective from October 2, 2026, cancels the single Union authorization granted by Implementing Regulation (EU) 2024/1481, which is expressly repealed.

This is not a change in conditions or a pending renewal: it is a total cancellation. Continuing to market or use this biocide without legal basis exposes the company to administrative sanctions whose amount is set by each Member State.

What does this regulation establish?

Implementing Regulation (EU) 2026/2199 acts on the basis of Regulation (EU) No. 528/2012, the European framework that regulates the marketing and use of biocidal products in all Member States. This framework allows the Commission to grant single Union authorizations for biocides—valid throughout European territory—and also to cancel them when the prescribed conditions are met.

The following table summarizes the specific regulatory change introduced by this regulation:

The cancellation affects all EU Member States simultaneously, since it was a single Union authorization—not individual national authorizations. There is no exception regime by country.

Economic and operational impact

The practical consequences of this cancellation translate into three areas of impact for companies:

• Immediate cessation of marketing: The authorization holders and their distributors must stop putting the product on the market. Any sale after the cancellation date (October 2, 2026) lacks legal basis.
• Stock management: Existing stocks cannot simply be ignored. The transition regulations of Regulation (EU) 528/2012 establish specific periods for their liquidation or disposal. Operating outside those periods implies risk of sanction.
• Search for alternatives: Professional and industrial users who depend on Nordkalk QL 0-2 for their processes must identify and approve alternative biocidal products with current authorization in the EU. This process may require time and internal validation costs.
• Risk of sanctions: Non-compliance with the obligations arising from the cancellation may result in administrative sanctions. The amount and sanctioning procedure are determined by each Member State, so the risk varies depending on the country of operation.

Who does it affect?

• Manufacturers of Nordkalk QL 0-2: Must cease production intended for the EU and manage the repeal of their authorization.
• Distributors and wholesalers: Obliged to halt marketing and manage warehouse stocks in accordance with transition periods.
• Professional and industrial users: Companies that use this biocide in their processes (water treatment, industrial disinfection, construction, agriculture or other authorized uses) must seek approved alternatives before exhausting their supplies.
• Importers: Any operator that imports the product from third countries for distribution in the EU is equally affected by the cancellation.
• Compliance and advisory managers: Must verify that their clients or companies do not maintain active supply contracts for this product.

Practical example

A biocide product distributor in Spain has a batch of Nordkalk QL 0-2 in its warehouse purchased in September 2026, before the cancellation. As of October 2, 2026, that stock cannot be marketed without further action: the company must comply with the transition periods established by Regulation (EU) 528/2012 for the liquidation of stocks of products whose authorization has been cancelled.

If the company continues to sell the product outside those periods—or without following the transition procedure—it is exposed to inspection and the administrative sanctions set by Spanish biocide regulations. At the same time, its industrial customers who used Nordkalk QL 0-2 urgently need an alternative authorized product, which may involve validation costs, changes to internal procedures and possible process shutdowns if action is not taken quickly.

What should companies do now?

1. Verify if Nordkalk QL 0-2 is part of your supply chain or processes: Review purchase contracts, product sheets and usage records to identify if the biocide is present in current operations.
2. Immediately halt marketing: As of October 2, 2026 there is no valid authorization. Any sale or distribution after that date must cease without delay.
3. Consult the applicable transition periods: Regulation (EU) 528/2012 provides for transition periods for stock management. It is essential to know the exact periods to avoid incurring an infraction.
4. Identify and approve alternative authorized products: Consult the ECHA Biocidal Products Registry to locate alternatives with current authorization in the EU.
5. Communicate the change to customers and suppliers: Inform the supply chain about the cancellation to prevent orders or contracts for a product without legal basis.
6. Document all actions: In case of inspection, the company must be able to prove that it acted in accordance with the transition periods and procedures established.
