Key Findings
The 11th revised edition of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), effective September 30, 2026, introduces new labeling and Safety Data Sheet (SDS) requirements specifically tailored for nanomaterial reagents. This regulatory change primarily targets products where at least 50% by weight of the particles are less than 100nm. It mandates detailed hazard classifications, dedicated new pictograms, and expanded sections within the SDS to address the unique characteristics of nanomaterials.
Regulatory Content
This GHS revision (UNECE Rev. 11) aims to enhance information dissemination by considering the peculiar physicochemical properties and potential health and environmental impacts of nanomaterials. Specifically, SDSs will now be required to explicitly state information such as nanomaterial morphology, size distribution, and surface characteristics. Hazard classifications will be applied based on the latest scientific understanding of exposure routes and toxicity mechanisms, providing users with clearer risk information. New pictograms have been designed to visually communicate hazards specific to nanomaterials.
Background & Context
With the advancement of nanotechnology, diverse nanomaterials have found widespread industrial applications, increasing the importance of their safety assessment and appropriate information transfer. Previously, the GHS was noted for its inability to fully cover the inherent risks of nanomaterials; this revision addresses that gap. Many countries, including those in the EU, have adopted GHS into their national legislation, making this revision crucial for promoting standardization and harmonization in international nanomaterial safety management. Chemical suppliers are now required to review existing product classifications and prepare labels and SDSs that comply with the new requirements.
Strategic Significance & Outlook
This new regulatory framework will compel all stakeholders involved in the development, manufacture, distribution, and use of nanomaterials to adopt more stringent safety management practices. Users are expected to benefit from greater transparency in hazard information, leading to improved safe handling of nanomaterials. In the long term, this will likely accelerate safety research and the development of innovative safety technologies for nanomaterials, contributing to the sustainable growth of nanotechnology. For businesses, this translates into strengthened compliance and enhanced market competitiveness through the provision of reliable products.
