EC Inventory is a historical chemical substance inventory maintained by ECHA, based on data received from the Joint Research Centre in 2008. It includes EINECS ("European INventory of Existing Commercial chemical Substances", existing substances on the EU market before 1981), ELINCS ("European LIst of Notified Chemical Substances", notified new substances after 1981), and NLP ("No-Longer Polymers", substances reclassified as non-polymers after 1992). It supports regulatory processes under EU chemicals legislation.
