Just Out of REACH

This report by the Center for International Environmental Law (CIEL) argues that the European Union's REACH regulation is currently ineffective at managing the health, safety, and environmental risks of nanomaterials. The author identifies four primary regulatory gaps—identification, phase-in status, tonnage thresholds, and risk assessment—that allow nanomaterials to enter the market with insufficient data, contradicting the "no data, no market" principle. The report proposes either modifying the REACH text or creating a stand-alone "nano patch" regulation to address these deficiencies.

• REACH lacks a formal definition of nanomaterials, leaving the decision of whether a substance is a nanomaterial to the discretion of the registrant. This inconsistency impairs the ability to use REACH as a tool for gathering market information and implementing risk management.
• Nanomaterials that share a chemical composition with a bulk substance automatically inherit that substance's "phase-in" status. This allows many nanomaterials to avoid registration until 2013 (for volumes over 100 tonnes per year) or 2018 (for 1-100 tonnes per year), regardless of whether the nano-form is new.
• The REACH registration threshold of one tonne per year is too high for nanomaterials, which are typically produced in much smaller quantities. Consequently, many nanomaterials fall below the threshold for basic regulation, rendering the "no data, no market" principle ineffective.
• Existing risk assessment and testing guidelines under REACH are designed for bulk chemicals and fail to account for the unique hazards and exposure pathways of nanomaterials, such as their ability to cross the blood-brain barrier or olfactory mucosa.
• The current regulatory framework may inadvertently discourage the generation of risk data. If a bulk substance is classified as non-hazardous, that classification extends to its nano-form, meaning no additional data on nano-specific effects is required throughout its life cycle.
• The report argues that modifying non-binding Technical Guidance Documents (TGDs) is insufficient because registrants still maintain flexibility in their application. A more substantial modification of the regulatory framework is required.
• CIEL proposes two policy options: first, modifying the REACH text to include a nanomaterial definition, remove nano-forms from phase-in status, lower tonnage triggers, and mandate Chemical Safety Assessments (CSA) for all nanomaterials.
• As a second option, the report suggests a stand-alone "nano patch" regulation. This would be a flexible instrument specifying how REACH tools apply to nanomaterials, including a proposed precautionary registration threshold of 10 kilograms.
