How to Select a REACH Only Representative: A Due Diligence Guide

For a non-EU manufacturer preparing for EU REACH compliance deadlines, particularly with an eye toward 2026, what constitutes a truly robust due diligence process for selecting an Only Representative (OR)? Moving beyond a simple price comparison, how can a company construct a detailed evaluation framework to ensure the chosen OR is a competent, long-term strategic partner? This evaluation should dissect several key areas. First, regarding technical and regulatory expertise, what specific evidence should be requested to verify an OR’s experience with substances of similar complexity and tonnage bands? How should a manufacturer assess an OR’s documented procedures for critical tasks like SIEF (Substance Information Exchange Forum) communication, lead registrant negotiation, and the development of a comprehensive chemical safety report (CSR)? Second, in terms of legal and contractual safeguards, what specific clauses are essential in the OR agreement to clearly define data ownership, intellectual property rights for the registration dossier, and liability distribution? What is the best practice for outlining a clear and fair exit strategy, including the process and costs for transferring the registration to another OR, should the need arise in the future? Finally, concerning operational and financial transparency, how can a manufacturer look past the initial registration quote to understand the full spectrum of potential long-term costs? This includes inquiring about annual management fees, charges for dossier updates triggered by new ECHA requirements, and the OR’s policy for passing through consortium or ECHA-related fees. What project management and communication systems should a prospective OR have in place to provide consistent, transparent updates on registration progress and ongoing compliance obligations? --- *This Q&A was AI-assisted and reviewed for accuracy by Lo H.
