Biocidal products are tightly regulated in the EU and UK to ensure they are effective against target organisms while protecting human health and the environment. This framework governs product approval, active substance approval, labelling, and ongoing market surveillance across both regions.
The EU Biocidal Products Regulation (BPR) (Regulation (EU) No 528/2012) and the retained GB BPR set detailed rules for active substance approval, product authorisation, classification, packaging, and labelling.

What counts as a biocide

A biocidal product is any substance or mixture, in the form supplied to the user, that contains or generates one or more active substances with the primary purpose of destroying, deterring, rendering harmless, preventing the action of, or otherwise exerting a controlling effect on harmful organisms. Typical examples include disinfectants, preservatives, rodenticides, insecticides, and antifouling products.

Deciding whether a product is a biocide or not:

• Purpose: Is the primary function to control harmful organisms (for example, disinfect, preserve, or kill pests), rather than simply clean or perfume?

• Mode of action: Does the product work through an active substance or mechanism specifically intended to control a target organism?

• Claims and presentation: Do the label, marketing, or instructions state biocidal claims (for example, “disinfectant”, “kills 99.9% of bacteria”, “insecticide”, “mould remover”)?

If a product’s main function is not to control harmful organisms, it may fall under other legislation (such as cosmetics, detergents, or general chemicals) rather than the biocides regime.

Core obligations include:

• Definition: Confirm that the product clearly meets the legal definition of a biocidal product.

• Active substances: Use only active substances that are approved or under review for the relevant product type and market.

• Authorisation: Obtain the correct product authorisation(s) (EU/UK BPR registrations) before placing the product on the market in each territory.

• Classification: Classify and package the product in line with CLP requirements, including appropriate child‑resistant closures and tactile warnings where needed.

• Labelling: Ensure all mandatory biocide‑specific and CLP labelling elements are present, legible, and in the correct language(s).

  Efficacy: Hold robust test data to substantiate all biocidal claims under realistic use conditions.

• Good manufacturing practice: Manufacture under appropriate quality systems to ensure consistency with the authorised formulation.

• Documentation: Maintain a complete technical dossier (PIF), including SDS, risk assessments, exposure scenarios, and authorisation decisions.

• Stewardship: Monitor adverse effects, resistance issues, and misuse, and update risk‑management measures where necessary.

Markings and information

Biocidal products must be labelled clearly and indelibly with all mandatory information before being placed on the EU or UK market.

As a minimum, labels must include: trade name and product type, name and address of the authorisation holder (and, where different, the manufacturer or distributor), authorisation number(s) for the EU and/or GB, identity and concentration of each active substance, including any nanomaterials, type of formulation, intended uses, clear instructions for use, including contact times, dilution rates, and application method, safety phrases (CLP): hazard and precautionary statements, pictograms, and signal word derived from the product’s classification, information on first aid, safe storage and disposal, and any specific measures to protect humans, animals, and the environment, and where required, information on treated articles and any specific restrictions (for example, “For professional use only”).

Labelling must be in the official language(s) of the country of sale and must not be misleading—for example, by understating risks or overstating performance.

How we can help

CERT supports businesses in navigating EU and UK biocides frameworks. We help determine whether your product is a biocidal product, advise on active substance and product authorisation routes, and assess labelling, claims, and classification. Our services include PIF preparation, SDS and label reviews, test report reviews, and ongoing support with variations, renewals, and regulatory changes.
With tailored, end‑to‑end solutions, CERT helps you launch biocide products that are safe, compliant, and ready for market—backed by clear documentation and expert support.
