Nanomaterials as defined in a 2011 Commission Recommendation are materials which often have specific properties due to their small particle size.

The global market for nanomaterials is estimated at 11 million tonnes at a market value of EUR 20 billion. The current direct employment in the nanomaterial sector is estimated at 300 000 to 400 000 in Europe. It is still dominated by materials which have been in use for decades, such as carbon black (mainly used in tyres) or synthetic amorphous silica (used in a wide variety of applications including tyres, as polymer filler but also in toothpaste or as anticoagulant in food powders).

In the past years, many new nanomaterial-related applications have been developed. Those include a number of consumer products such as UV-filters in sun creams and anti-odour textiles. However, many medical and technical applications such as tumour therapies, lithium-ion batteries which can drive electrical cars, or solar panels also exist. Those applications have the potential to create major technological breakthroughs, and therefore nanomaterials have been identified as a key enabling technology. Products underpinned by nanotechnology are forecast to grow from a global volume of EUR 200 billion in 2009 to EUR 2 trillion by 2015.

In the light of current knowledge and opinions of the EU Scientific and Advisory Committees and independent risk assessors, nanomaterials are similar to normal chemicals/substances in that some may be toxic and some may not. Possible risks are related to specific nanomaterials and specific uses. Therefore, nanomaterials require a risk assessment, which should be performed on a case-by-case basis, using pertinent information. Current risk assessment methods are applicable, even if work on particular aspects of risk assessment is still required.

The 2012 Communication on the Second Regulatory Review on Nanomaterials describes the Commission’s plans to improve EU law and its application to ensure their safe use. It is accompanied by a Staff Working Paper on nanomaterial types and uses, including safety aspects, which gives a detailed overview of available information on nanomaterials on the market, including their benefits and risks. The Communication was presented at a workshop on 30 January 2013, for which the presentations are available.

Nanomaterials in REACH and CLP

Nanomaterials are regulated by REACH and CLP because they are covered by the definition of a chemical "substance" in both Regulations. The general obligations in REACH and CLP therefore apply as for any other substance, although there are no provisions referring explicitly to nanomaterials.

REACH provides an over-arching legislation applicable to the manufacture, placing on the market and use of substances on their own, in preparations or in articles. The general obligations in REACH, such as registration of substances manufactured at 1 tonne or more and providing information in the supply chain apply as for any other substance.

The first registration deadline under REACH (30 November 2010) applied to substances manufactured or imported at ≥1000 t/y, carcinogenic, mutagenic and reproductive (CMR) substances at ≥1 t/y and persistent, bioaccumulative and toxic (PBT) of very persistent and very bioaccumulative (vPvB) substances ≥100 t/y. The second registration (1 June 2013) applied to volumes higher than 100 tonnes and lower than 1000 tonnes per year, while the remaining substances manufactured or imported at 1-100 t/y have to be registered by 1 June 2018. The European Chemicals Agency (ECHA) receives the registrations and the Agency plays a central role in the collection, evaluation and dissemination of information on substances and preparations, including nanomaterials.

Nanomaterials that fulfill the criteria for classification as hazardous under Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures must be classified and labelled. Many of the related provisions, including safety data sheets and classification and labelling apply already today, independently of the tonnage in which the substances are manufactured or imported. Substances, including nanomaterials, meeting the classification criteria as hazardous and put on the market must be notified to ECHA.

In close co-operation with the CARACAL subgroup on nanomaterials ("CASG Nano", composed of Member States Competent Authorities and stakeholder experts) the Commission advises on how to manage nanomaterials safely in accordance with REACH and the CLP Regulation and assess possible further legislative modifications. ECHA has published advice on how to enter nanomaterial information in IUCLID and on best practices with nanomaterials’ registration, updated the guidance for nanomaterials and has created a Nanomaterial Working Group supporting the implementation of REACH, CLP and Biocides Regulation ECHA, together with the Member States has also included some substances with nanoforms in the CORAP list of substances to be evaluated in 2014-2016. Furthermore, the Classification and Labelling Inventory and the web portal on Registered substances of ECHA also contain information on substances with nanoforms.

A study contracted by DG Enterprise and Industry on the development of emerging technologies indicates that REACH and CLP may cause administrative burden, affect time to market, marginal cost structure and allocation of resources, especially for SMEs. However, a few companies also foresee them to create new business opportunities and contribute to consumer and investor confidence in the technology.

The Commission concludes on the basis of the Communication of second Regulatory review on Nanomaterials that REACH sets the best possible framework for the risk management of nanomaterials when they occur as substances or mixtures but more specific requirements for nanomaterials within the framework have proven necessary. The Commission envisages modifications in some of the REACH Annexes and encourages ECHA to further develop guidance for registrations. The Commission will make an impact assessment of relevant regulatory options, in particular possible amendments of REACH Annexes, to ensure further clarity on how nanomaterials are addressed and safety demonstrated in registration dossiers.

Study to support the Impact Assessment of relevant regulatory options for nanomaterials in the framework of REACH (March 2014):

This study has been undertaken to support the drafting of the forthcoming Impact Assessment for an amendment of relevant Annexes to the REACH Regulation with regard to Nanomaterials (NM), which pursues the objective “to ensure further clarity on how NM are addressed and safety demonstrated in registration dossiers”.

The study includes an assessment of future options to address NM under REACH while taking into account, on the one hand, the competitiveness of the European chemicals and NM sector, innovation and employment, including SME-specific impacts, and on the other hand, human health and the environment and impacts from the use of NM.

Transparency measures for nanomaterials


As part of the Second Regulatory Review on Nanomaterials , the Commission announced to launch “an impact assessment to identify and develop the most adequate means to increase transparency and ensure regulatory oversight [on nanomaterials].”

This impact assessment on transparency measures for nanomaterials was initiated in 2013 as a response to concerns about potentially inadequate action on health and environmental risks of nanomaterials and potentially suboptimal consumer choices as a result of lack of information available to authorities, users, distributers, workers and consumers. Over the course of the impact assessment exercise, a number of policy options are defined, refined and assessed, such as a single nanoregistry at an EU level with different variations, a nanomaterials observatory, a recommendation on best practices for national registries or no additional action compared to the current legal framework. General information about impact assessments can be found on the European Commission's dedicated website.


A study was launched to evaluate existing notification systems for nanomaterials and to collect data in support of the impact assessment. The contractors (RPA and BiPro) have made the following reports available:
