Factors Defining a REACH Only Representative's Scope & Services

## A Comprehensive Guide to a REACH Only Representative's Scope and Services For manufacturers based outside the European Union, appointing a REACH Only Representative (OR) is an essential strategic decision for accessing the EU market. This legal entity, established within the EU, assumes the responsibilities of an importer under the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation, allowing the non-EU manufacturer to manage their compliance centrally. While the specific services and fees can vary significantly between providers, the scope of an OR’s work is determined by a consistent set of factors rooted in the substance's properties, import volume, and supply chain complexity. Understanding these key drivers is crucial for non-EU companies to accurately budget for compliance, select the right OR partner, and ensure long-term market access. The complexity of an OR's role extends far beyond a simple registration; it involves ongoing data management, supply chain communication, and regulatory vigilance. The primary factors influencing this scope include the annual tonnage of the substance imported, its intrinsic hazard profile, the intricacy of the EU supply chain, and the availability of required technical data. ### Key Points * **Tonnage Band is Paramount:** The REACH regulation categorizes obligations based on the volume of a substance placed on the market annually (e.g., 1-10, 10-100, 100-1000, 1000+ tonnes per year). Higher tonnage bands require significantly more data, a comprehensive Chemical Safety Report (CSR), and more extensive registration efforts, directly increasing the OR's workload. * **Hazard Profile Drives Complexity:** Substances with hazardous properties, especially those identified as Substances of Very High Concern (SVHC) or classified as Carcinogenic, Mutagenic, or toxic for Reproduction (CMR), demand a much higher level of scrutiny. This includes developing detailed Exposure Scenarios and ensuring robust communication of risk management measures down the supply chain. * **Supply Chain Dictates Communication Load:** An OR is the central communication hub. A manufacturer selling to numerous downstream users across various industries will require more intensive management of Safety Data Sheets (SDS), exposure information, and volume tracking than one selling to a single distributor. * **Data Access is a Major Factor:** The "one substance, one registration" principle requires participation in a Substance Information Exchange Forum (SIEF). The OR's role can range from simple participation to complex negotiations for data access (via a Letter of Access) or managing new testing if data gaps exist. * **Post-Registration is Not the End:** An OR's duties are ongoing. They include dossier updates, responding to ECHA evaluations, monitoring for new substance classifications, and continuous volume tracking, all of which must be factored into the service scope. ### ## Understanding the Core Factors That Define an OR's Scope The responsibilities of a REACH Only Representative are multifaceted. A clear understanding of the following areas will help non-EU manufacturers evaluate proposals from OR service providers and anticipate the level of support required. #### ### 1. Substance Volume and Tonnage Bands The most direct factor influencing the scope of work is the total volume of the substance the non-EU principal intends to place on the EU market per year. REACH obligations are tiered according to tonnage bands. * **1–10 tonnes/year:** This is the lowest band requiring registration. The data requirements are less extensive, and a full Chemical Safety Report (CSR) is generally not required unless the substance meets specific hazard criteria. The OR's role focuses on compiling the technical dossier with available data, managing the SIEF, submitting the registration via IUCLID, and performing basic volume tracking. * **10–100 tonnes/year:** The data requirements increase significantly. A Chemical Safety Report (CSR) is mandatory for any substance classified as hazardous. The OR's work expands to include chemical safety assessment and, if necessary, the development of Exposure Scenarios (ES) to be annexed to the Safety Data Sheet. * **100–1000 tonnes/year and 1000+ tonnes/year:** These highest bands require the most comprehensive data sets, including information on long-term toxicity and ecotoxicity. The CSR is more detailed, and the OR's role becomes more intensive in terms of data analysis, risk assessment, and dossier management. The OR is legally responsible for tracking the cumulative volume imported by all of the manufacturer's EU customers to ensure the registered tonnage band is not exceeded. #### ### 2. Substance Properties and Hazard Profile Beyond volume, the intrinsic properties of the chemical substance are a critical determinant of an OR's workload. * **Hazardous Substances:** If a substance is classified as hazardous under the Classification, Labelling and Packaging (CLP) Regulation, the OR must ensure that this is correctly reflected in the registration dossier and communicated via compliant Safety Data Sheets. * **Substances of Very High Concern (SVHCs):** If a substance is on the REACH Candidate List as an SVHC, the communication and reporting obligations intensify dramatically. The OR must manage communications regarding the presence of the SVHC in articles and may need to support the manufacturer through the complex Authorisation process if the substance is later added to the Authorisation List (Annex XIV). * **Chemical Safety Assessment:** For hazardous substances imported at over 10 tonnes/year, the OR must oversee the Chemical Safety Assessment (CSA) and the creation of a Chemical Safety Report (CSR). This involves identifying uses, developing Exposure Scenarios for each use, and outlining the necessary Risk Management Measures (RMMs) to ensure safe handling. This is a highly technical task that requires significant expertise. #### ### 3. Supply Chain Complexity and Communication The OR acts as the legal representative to authorities and the primary communication link to the EU supply chain. The complexity of this role scales with the size and diversity of the customer base. * **Downstream User Communication:** The OR is responsible for providing downstream users (your EU customers) with safety information, primarily through the SDS. For substances requiring a CSR, the OR must compile and distribute an extended-SDS (e-SDS) containing the relevant Exposure Scenarios. * **Volume Tracking:** A non-EU manufacturer may sell to dozens or even hundreds of importers in the EU. The OR must implement a robust system to collect import volume data from all these customers to ensure the total amount remains within the registered tonnage band. * **Use Mapping:** The OR needs to understand how downstream users use the substance to ensure these uses are covered in the registration dossier and the chemical safety assessment. A wide variety of uses across different industries adds significant complexity to this task. ### ## Scenario-Based Examples To illustrate how these factors interact, consider two contrasting scenarios. #### ### Scenario 1: A Low-Volume, Non-Hazardous Substance * **Substance:** A specialty polymer intermediate, not classified as hazardous. * **Volume:** 8 tonnes per year. * **Supply Chain:** Sold to a single, exclusive EU distributor who formulates it into a final product. * **OR Scope of Work:** * **Registration:** Compile a registration dossier for the 1-10 tonnes/year band. A CSR is not required. * **SIEF Management:** Engage with the SIEF to purchase a Letter of Access for the required data. * **Communication:** Provide a standard SDS to the single distributor. * **Volume Tracking:** Monitor annual imports from the one distributor to ensure they remain below 10 tonnes. * **Overall Complexity:** Low. The role is primarily administrative and focused on the initial registration with minimal ongoing communication needs. #### ### Scenario 2: A High-Volume, Hazardous Substance * **Substance:** An industrial solvent classified as a CMR substance (Category 1B). * **Volume:** 150 tonnes per year. * **Supply Chain:** Sold to 30 different downstream users across the EU for various applications (e.g., cleaning, coating, chemical synthesis). * **OR Scope of Work:** * **Registration:** Compile a full registration dossier for the 100-1000 tonnes/year band. * **Chemical Safety Assessment:** Conduct a comprehensive CSA and author a detailed CSR, including developing multiple Exposure Scenarios to cover all identified uses in the diverse supply chain. * **SIEF Management:** Actively participate in the SIEF, potentially negotiating data-sharing costs and contributing to dossier updates. * **Communication:** Develop, maintain, and distribute a complex e-SDS to all 30 customers. Manage inquiries from downstream users regarding safe use conditions. * **Volume Tracking:** Implement a robust system to collect and aggregate import data from all 30 customers on a regular basis. * **Regulatory Monitoring:** Actively monitor the substance's regulatory status, as its CMR classification makes it a candidate for future restrictions or authorisation requirements. * **Overall Complexity:** High. The role is strategic, technical, and continuous, requiring deep regulatory expertise and sophisticated management systems. ### ## Strategic Considerations When Selecting an Only Representative Choosing an OR is more than a compliance checkbox; it's a long-term partnership. Non-EU manufacturers should assess potential ORs based on their ability to handle the expected scope of work. Key questions to ask include: * **Experience:** Do you have experience with substances similar to ours (e.g., polymers, inorganics, SVHCs)? * **Systems:** What systems do you use for volume tracking across multiple importers? * **Technical Expertise:** Do you have in-house toxicologists and regulatory experts to manage a complex CSR and Exposure Scenarios? * **Communication:** How do you manage SIEF communications and negotiations? How will you keep us informed of regulatory changes? * **Service Model:** Do you offer ongoing support for dossier updates and communication, or is your service focused only on the initial registration? ### ## Finding and Comparing REACH Only Representative Providers Finding a qualified and reliable Only Representative is critical for successful and sustained market access in the EU. When evaluating providers, manufacturers should look for a partner with proven technical expertise, transparent communication practices, and robust systems for managing compliance.
