The European Union’s (EU's) Registration, Evaluation and Authorization of Chemicals (REACH) regulation places responsibility on manufacturers, importers, and downstream users to register the chemicals in products sold in the EU.

Since 2001 Tetra Tech has assisted more than 2,000 companies in complying with EU environmental regulations, including REACH, Restrictions on the Uses of Certain Hazardous Substances (RoHS), and the End-of-Life Vehicles Directive (ELV).

REACH requires industry to demonstrate the safety of these chemicals with test data and exposure scenario modeling. Chemicals that influence reproductive and developmental health at certain doses get special attention. REACH also mandates that industry communicate any hazards or risks throughout the supply chain.

The influence of the EU’s regulations is being felt around the world. EU-based customers are asking North American-based companies for legal proof that their products are REACH compliant. With consulting, training, and data management solutions, Tetra Tech is helping these companies meet legislative mandates and operate their businesses in an efficient and environmentally responsible manner.

Companies that produce articles (items that get included in a finished product) are also feeling an impact as they try to determine which substances are included in the regulation and what data they need to share with EU regulators and customers. Using existing data first, Tetra Tech can help articles producers rapidly conduct substance inventories with their supply chains—a rational solution that minimizes the time and effort for compliance determination and report generation.

Using resources within our North American and EU-based offices, Tetra Tech is in a unique position to help North American companies understand new REACH requirements and how they influence business.

Turnkey Product Registration

Tetra Tech can arrange for an “Only Representative” scenario where companies and their customers do not need to incur the legal obligations that apply to an importer. This is a way for a company to differentiate itself from competitors, because REACH compliance is outsourced and customers need not worry about risks of noncompliance.

SVHC Inventories

Since 2001 Tetra Tech has conducted EU regulation substance inventories for hundreds of manufacturers. With REACH, our approach is to first leverage existing Materials Safety Data Sheets, RoHS/ELV, and other environmental data. We then compare existing data with the data needed for REACH compliance. We rapidly conduct a substance inventory with the supply chain, compile this information into a database, and fill the gaps needed for REACH compliance. By using existing data, we can substantially lower REACH compliance costs.

REACH Compliance Database Implementations

The mountain of substance data generated in the course of REACH compliance requires an intelligent solution for data management. Our approach is to work with software to manage data through a combination of automation and expert analysis. This approach is a rational solution for minimizing the time and effort for compliance determination and report generation, without sacrificing data integrity.

Tetra Tech is an industry leader in providing product compliance services in Europe and North America. We are staffed with experienced consultants, materials scientists, and toxicologists who are experts in planning and implementing REACH programs.
