Cis-tricos-9-eno biocide renewed in the EU: what manufacturers and distributors must do in 2026

Key data

If your company manufactures, distributes or professionally uses biocides to repel birds or rodents containing cis-tricos-9-ene, this regulation affects you directly from 12 October 2026. Implementing Regulation (EU) 2026/2247 renews the approval of this active substance, but does so with specific conditions that require reviewing the entire product chain: from marketing authorization to labeling and technical data sheets.

The renewal is framed within the Regulation (EU) No 528/2012, which regulates the marketing and use of biocides throughout the European Union. This is not a new approval: it is a renewal, which means that companies already operating with this substance must confirm that their products continue to comply with the updated conditions.

What does this regulation establish?

Regulation 2026/2247 formally renews the approval of cis-tricos-9-ene for exclusive use in biocides of product type 19, that is, products intended to repel or attract birds and rodents. The key points it establishes are:

• The active substance cis-tricos-9-ene is approved to continue being used in type 19 biocides throughout the EU.
• Specific conditions are established to minimize risks to human health, animal health and the environment.
• Manufacturers and distributors must verify that their current product authorizations remain valid under the new conditions, or request their updating from the competent national authorities.
• Technical data sheets and labeling of affected products must be reviewed to ensure compliance with the new requirements.
• Failure to comply with the renewed conditions may result in the withdrawal of national marketing authorizations.

Economic and operational impact

For companies in the sector, this renewal is not an automatic formality. It involves real operational costs on several fronts:

• Review of authorizations: Each marketed product containing cis-tricos-9-ene has a national authorization. If the new conditions modify usage or safety requirements, that authorization must be updated. The process involves technical time and, in many cases, administrative fees to the competent national authority (in Spain, the Ministry of Health through the Official Register of Biocides).
• Update of technical data sheets and labeling: Any change in approval conditions requires reviewing and, if necessary, reformulating safety data sheets and label texts. This may require the intervention of a toxicologist or regulatory officer.
• Risk of commercial paralysis: If a company does not update its product authorization in time and national authorities initiate a review process, the product may be temporarily removed from the market. This means loss of sales and possible contractual penalties with customers.
• Phytosanitary and pest control sector: Professional users (pest control companies, managers of agricultural or industrial facilities) must also ensure that the products they use continue to have valid authorization under the new conditions.

Who does it affect?

• Biocide manufacturers that include cis-tricos-9-ene as an active substance in type 19 products.
• Distributors and marketers of these products in the Spanish and European market.
• Pest control companies that professionally use repellents or attractants for birds and rodents based on this substance.
• Managers of agricultural, livestock or industrial facilities that apply this type of biocide in their installations.
• Regulatory and quality officers of companies in the phytosanitary and crop protection sector.

Practical example

Imagine a Spanish distribution company that markets a bird repellent for use in agricultural facilities. The product contains cis-tricos-9-ene as an active substance and has a national marketing authorization obtained under the previous approval of the substance.

With the entry into force of Regulation 2026/2247 on 12 October 2026, this company must:

1. Check whether the new specific conditions established to minimize risks to human, animal and environmental health modify any of the requirements that supported its current authorization.
2. If there are changes, initiate the procedure to update the authorization with the competent national authority before the product becomes non-compliant.
3. Review the product's technical data sheet and labeling to reflect any new usage conditions or safety warnings required.

If the company does not act and the national authority detects that the product no longer complies with the renewed conditions, it may withdraw the marketing authorization, which would mean immediately removing the product from the market.

What should companies do now?

1. Identify affected products: Review your own or distributed product catalog to locate all products containing cis-tricos-9-ene as an active substance in type 19 biocides.
2. Verify the status of national authorizations: Check with the competent national authority (in Spain, the Ministry of Health) whether current authorizations remain valid under the conditions of Regulation 2026/2247 or require updating.
3. Review technical data sheets and labeling: Update technical documentation and label texts to reflect the new specific conditions for use and safety established in the renewal.
4. Initiate the update procedure if necessary: If the authorization requires modification, submit the request to the competent authority without delay to avoid interruptions in marketing.
5. Inform professional users: If you are a manufacturer or distributor, communicate to your professional customers any changes in the product's usage conditions so they can adapt their operational procedures.
