On March 18, 2026, the Commission Implementing Decision (EU) 2026/576 of March 17, 2026 was published in the Official Journal of the European Union, delaying the expiry date of the approval of basic copper carbonate as an active substance in product-type 8 biocides, corresponding to wood preservatives. This decision, adopted under Regulation (EU) No 528/2012 on biocidal products, is directly relevant to manufacturers and distributors of wood treatment and preservation products throughout the European Union, including those based in Spain. If your business is related to this sector, below we explain everything you need to know.
What does this regulation establish?
The European Commission has decided to delay the expiry date of the approval of basic copper carbonate as an active substance used in biocides classified as product-type 8, meaning products intended for wood preservation.
This extension is granted within the framework of Regulation (EU) 528/2012, which governs the placing on the market and use of biocidal products in the European Union. The usual reason for this type of decision is that the renewal process for the substance's approval is ongoing and could not be completed before the original expiry date, so the Commission extends its validity to avoid a legal gap that would harm market operators.
Among the key aspects you should know about this decision:
- The expiry of the current approval of basic copper carbonate in product-type 8 biocides is delayed.
- The extension allows for the legal continuity in the marketing of products containing this substance.
- No changes are introduced to the conditions of use of the substance or to existing labelling requirements.
- The decision entered into force on March 17, 2026, one day before its official publication.
Who is affected and how?
This regulation directly affects manufacturers and distributors of wood preservative biocides containing basic copper carbonate in their formulation. In practical terms, the most involved sectors are:
- Companies in the construction sector that use or market preventive treatment products for structural or decorative timber.
- Wood treatment industries, such as sawmills, outdoor furniture manufacturers, or prefabricated timber companies.
- Distributors of industrial maintenance products that include wood preservative biocides with this active substance in their catalogue.
For all of them, the immediate impact is positive and preventive in nature: thanks to this extension, they can continue manufacturing, distributing, and marketing their products with full legal certainty, without needing to withdraw them from the market or interrupt their activity while the renewal process of the approval at European level is completed.
It is important to emphasise that, since the conditions of use and labelling requirements are not modified, affected companies do not need to make changes to their products, packaging, or technical documentation as a direct consequence of this decision.
What should you do to adapt?
Although this regulation does not impose new immediate obligations, it does require affected companies to stay informed of their regulatory situation. We recommend the following action steps:
- Verify whether your products are affected: Check whether any of the biocides you manufacture or distribute contain basic copper carbonate as an active substance and are classified as product-type 8 (wood preservatives).
- Keep your regulatory documentation up to date: Although there are no changes to the conditions of use or labelling, it is advisable to record the existence of this extension and its official reference in your compliance file.
- Follow the renewal process: Since the approval is undergoing renewal, stay alert to future publications in the Official Journal of the EU that may establish new conditions or definitive deadlines once that process is concluded.
- Consult your legal or regulatory advisor: If you have doubts about how this decision specifically affects your product portfolio or your registration obligations, consult a professional specialised in biocidal product regulations.
- Review the original regulation: To learn the specific details, exact deadlines, and applicable technical conditions, consult the official source linked at the end of this article directly.
