Understanding the Role of an Only Representative under EU REACH
The European Union’s Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation is one of the most comprehensive chemical regulatory frameworks in the world. Designed to protect human health and the environment, EU REACH places strict requirements on companies manufacturing or importing substances into the EU.
For non-EU manufacturers, one of the most effective ways to maintain market access and compliance is by appointing an Only Representative (OR).
What Is an Only Representative?
Under Article 8 of EU REACH, an Only Representative is an EU-based legal entity appointed by a non-EU manufacturer, formulator, or producer of articles to fulfill the obligations that would otherwise apply to their EU importers.
In effect, the Only Representative acts on behalf of the non-EU manufacturer to ensure that all substances placed on the European market are properly registered with the European Chemicals Agency (ECHA).
- Relieve EU importers of REACH registration obligations.
- Protect confidential business information, including substance identity and composition.
- Maintain uninterrupted access to EU markets without establishing an EU subsidiary.
Why Appoint an Only Representative?
Appointing an Only Representative offers both regulatory and commercial advantages. For non-EU manufacturers, it provides direct control over REACH compliance, ensuring that their products remain on the European market without placing regulatory obligations on customers.
- Register substances on behalf of the non-EU manufacturer through REACH-IT.
- Coordinate data sharing and Letters of Access through Substance Information Exchange Forums (SIEFs).
- Prepare and maintain the Chemical Safety Report (CSR) and exposure scenarios.
- Manage ongoing dossier updates and communications with ECHA and national authorities.
Appointing an OR also streamlines supply chains by allowing EU importers to operate as downstream users rather than registrants, significantly reducing their compliance burden.
