EC-Number
The EC-number, i.e. EINECS, ELINCS or NLP, is the official number of substances within the European Union. In the REACH-process some substances were presented at ECHA which did not previously have an assigned EC-Number, or were contained in a dossier for which a registrant did not indicate the existing assigned EC-Number. These substances may have been assigned a List Number by ECHA. The EC-number is a seven-digit system of the type XXX-XX-X, in which the last digit is a check digit.
In the following table the EC-numbers and List Numbers and their respective status are given.
European Inventory of Existing Commercial Chemical Substances (EINECS):
- These are substances, excluding polymers, that were commercially available in the EU from 1 January, 1971 to 18 September, 1981. These were considered to be registered under Article 8(1) of directive 67/548/EEC. The identifying number of these substances is called the EINECS-number.
European List of New Chemical Substances (ELINCS):
- These are substances that became commercially available after 18 September, 1981. The identifying number of these substances is called the ELINCS-number.
The "No-longer Polymers" list (NLP-list):
- The European definition of polymers was changed in April 1992 with the result that substances previously considered to be polymers were no longer excluded from regulation. Consequently, a list, called the NLP-list, was made of such substances that were commercially available between 18 September 1981 and 31 October 1993. The identifying number of these substances is called the NLP-number.
