Term Definition
Actor in the supply chain All manufacturers and/or importers and/or downstream users in a supply chain of a substance.
Agency The authority established by the Secretary of State to carry out the obligations arising from the REACH Regulation.
Article An object which during production is given a special shape, surface or design, which determines its function to a greater degree than does its chemical composition. Examples of articles are a car, a battery and a telephone.
CLP The Classification, Labelling and Packaging (CLP) Regulation ((EC) No 1272/2008) is based on the United Nations' Globally Harmonised System (GHS). Its purpose is to ensure manufacturers, importers or downstream users of substances or mixtures classify, label and package their hazardous chemicals appropriately before placing them on the market.
CSA Chemical Safety Assessment. This is carried out for all registered substances manufactured or imported at 10 tonnes per year or greater. It should address all the identified uses of a substance on its own (including any major impurities and additives), in a mixture and in an article. The assessment shall consider all stages of the life-cycle of the substance resulting from the manufacture and identified uses. The chemical safety assessment shall be based on a comparison of the potential adverse effects of a substance with the known or reasonably foreseeable exposure of man and/or the environment to that substance taking into account implemented and recommended risk management measures and operational conditions.
CSR Chemical Safety Report. A CSR should be completed for all substances subject to registration in quantities of 10 tonnes or more per year per registrant and is a documentation of the chemical safety assessment (see above).
Distributor Any natural or legal person established within the United Kingdom including a retailer, who only stores and places on the market a substance, on its own or in a mixture for third parties.
Downstream User Any natural or legal person established within the United Kingdom, other than the manufacturer or the importer, who uses a substance, either on its own or in a mixture, in the course of his industrial or professional activities. A distributor or a consumer is not a downstream user.
Downstream User Import Notification (DUIN) Transitional provision in UK REACH for GB-based downstream users and distributors under EU REACH that they wish to continue importing substances into GB from EU. This notification must be made within the first 300 days of the date of Exit.
EINECS European Inventory of Existing Commercial Chemical Substances . EINECS is an inventory of substances that were deemed to be on the European Community market between 1 January 1971 and 18 September 1981
ESR Existing Substances Regulation. This is one of the pieces of EU legislation replaced by REACH.
European Chemicals Agency (ECHA) The Agency established for the purposes of managing and in some cases carrying out the technical, scientific and administrative aspects of the REACH Regulation and to ensure consistency at European Union level in relation to these aspects.
Exposure Scenario The set of conditions, including operational conditions and risk management measures, that describe how a substance is manufactured or used during its life-cycle and how the manufacturer or importer controls, or recommends downstream users to control, exposures of humans and the environment. These exposure scenarios may cover one specific process or use or several processes or uses as appropriate.
Grandfathering Transitional provision in UK REACH that recognises GB-based EU REACH registrations in UK REACH at the point the Transition Period ends.
Import The physical introduction into the United Kingdom.
Importer Any natural or legal person established within the United Kingdom who is responsible for import.
IUCLID International Uniform ChemicaL Information Database (IUCLID). A software to record, store, maintain and exchange data on intrinsic and hazard properties of a chemical substance.
Manufacture The production or extraction of substance in the natural state.
Mixture A mixture or solution composed of two or more substances
Natural or legal person A natural person is an individual person, also including self-employed people, sole traders or people in partnerships. A legal person is not a specific individual but something with a legal personality such as limited companies, trusts, charities etc.
NLP 'No Longer Polymers' are a group of substances that were once considered to be polymers (and so not listed on EINECS) and were also not notified under the original (6th Amendment) NONS legislation. The introduction of a new polymer definition in 1993 led to these substances losing their polymer status, however they remained exempt from notification under NONS. To qualify as a NLP a substance must have been on the market between September 18th 1981 and October 31st 1993 (inclusive) and satisfy the requirement that they were considered polymers under the reporting rules for EINECS, but were no longer considered polymers under the 7th Amendment (92/32/EEC).
Non-isolated intermediate A substance that is manufactured solely for the purpose of being transformed into another substance (or synthesis) and is used up within this reaction. This type of intermediate is not intentionally removed from the synthesising equipment (except for sampling). NOTE: this equipment does not include tanks or other vessels in which the substances is stored after manufacture.
Non-Phase-in substance A new substance, one not covered by the definition of a phase in substance.
NONS Notification of New Substances Regulations. Directive 67/547/EEC (also called NONS) formed part of the old EU chemicals regulatory framework which was replaced by REACH.
Only representative A person or legal entity established physically in the United Kingdom, who has been appointed by a mutual agreement with a manufacturer, formulator or article producer, established outside the United Kingdom, and who takes over the registration obligations of an importer of a substance under REACH.
On-site isolated intermediate A substance manufactured for and consumed in or used for chemical processing in order to be transformed into another substance, the synthesis of which takes places on the same site which is operated by one or more legal entities.
Phase in substance A substance which meets at least one of the following criteria:
  1. It is listed in the European Inventory of Existing Commercial Chemical Substances (EINECS).
  2. It was manufactured in the European Community, or in the countries acceding to the European Union on 1 January 1995, on 1 May 2004, on 1 January 2007 or on 1 July 2013 but not placed on the market by the manufacturer or importer, at least once in the 15 years before 1 June 2007 the entry into force of this Regulation, provided the manufacturer or importer has documentary evidence of this.
  3. It was placed on the market in the European Community, or in the countries acceding to the European Union on 1 January 1995 , on 1 May 2004 , on 1 January 2007 or on 1 July 2013 , by the manufacturer or importer before 1 June 2007 and it was considered as having been notified in accordance with the first indent of Article 8(1) of Directive 67/548/EEC in the version of Article 8(1) resulting from the amendment effected by Directive 79/831/EEC, but it does not meet the definition of a polymer as set out in this Regulation, provided the manufacturer or importer has documentary evidence of this, including proof that the substance was placed on the market by any manufacturer or importer between 18 September 1981 and 31 October 1993 inclusive;
Placing on the market Supplying or making available, whether in return for payment or free of charge, to a third party. Import shall be deemed to be placing on the market.
Product and Process Orientated Research and development (PPORD) Any scientific development of a product, or the further development of a substance on its own, in mixtures or in articles, in the course of which pilot plant or production trials are used to develop the production process and/or to test the fields of application of the substance.
(Q)SAR (Quantitative) Structure Activity Relationships are computer-based models which are designed to predict the physico-chemical properties, human health and environmental effects of a substance from knowledge of its chemical structure. Some models are qualitative and give an indication of a likely effect rather than try to quantify that effect.
Read-across Read-across is a method of filling in data gaps for a substance by using surrogate data from another substance. Read-across can be between two substances or through a group or category of chemicals. The groups are selected on the assumption that the properties of a series of chemicals with common structural features will show similar trends in their physico-chemical properties and in their toxicological effects or environmental fate properties.
Registrant The manufacturer or the importer of a substance or the producer or importer of an article submitting a registration for a substance.
Safety Data Sheet The Safety Data Sheet provides a mechanism for transmitting appropriate safety information on classified substances and mixtures, including information from the relevant Chemical Safety Report down the supply chain to the immediate downstream users. The information provided in the Safety Data Sheet shall be consistent with the information in the Chemical Safety Report, where one is required.
Scientific research and development Any scientific experimentation, analysis or chemical research carried out under controlled conditions in a volume less than a tonne a year.
Substance A chemical element and its compounds in the natural state or obtained by any manufacturing process, including any additive necessary to preserve its stability and any impurity deriving from the process used, but excluding any solvent which may be separated without affecting the stability of the substance or changing its composition.
Substances of very high concern (SVHC) Priority given to substances with SVHC properties which are registered for non-intermediate uses within the scope of authorisation. The substance groups for which activities need to be planned and carried out are:
  • CMRs (substances that are carcinogenic, mutagenic or toxic for reproduction)
  • PBTs (substances that are Persistent, Bio accumulative or Toxic for the Environment)
  • vPvBs (substances that are very Persistent and very Bio accumulative)
  • substances of equivalent concern (such as endocrine disruptors or sensitisers)
Supplier Any manufacturer, importer or downstream users or distributor placing on the market a substance, on its own, in a mixture or in an article.
Third party representative Appointed by a manufacturer, or importer, or downstream user, they play a part in the negotiations between the (potential) registrants, while the appointing company retains full responsibility for complying with its registration obligations.
Transported isolated intermediate A substance manufactured for and consumed in or used for chemical processing in order to be transformed into another substance, the synthesis of which is transported between or supplied to other sites.
