Approval of Commodity Substances - An Introduction

Commodity substances are chemicals which have a variety of non-pesticide uses as well as minor uses as pesticides. If such a substance is to be used as a pesticide, it requires approval under the Control of Pesticides Regulations (COPR), and is granted approval for use only.

Sale, supply, storage and advertisement of a commodity substance as a pesticide is an offence unless specific approval has been granted for the substance to be marketed as a pesticide under an approved label. Anyone wishing to sell, supply, store or advertise any of these substances specifically as pesticides has to seek specific approval under COPR.

Information about the status of commodity substances for plant protection and biocidal uses are given below. The approval schedule detailing the conditions of use which a user must follow when using the commodity substance can be viewed by clicking on the substance name.

Plant Protection Uses

Currently approved commodity substances

The following substances were added to Annex I of Directive 91/414/EEC via Commission Directive 2008/127/EC. New EU legislation for plant protection products (Regulation (EC) No. 1107/2009) replaced Directive 91/414/EEC from 14 June 2011. These substances have since been transferred to Commission Implementing Regulation (EU) No 540/2011, which implements Regulation (EC) No 1107/2009 regarding the list of approved active substances.

Article 23 of Regulation (EC) No. 1107/2009 introduces harmonised arrangements for approval of commodity substances, which are known as ‘basic substances’ in the EU regime. We will issue further advice on the possible approval of these commodity substances as basic substances when they are reviewed / renewed.
