Substance phase-in/non phase-in status and NONS allocation

At the registration level phase-in/non phase-in status is derived by the status indicated by the company in the registration dossier. At the substance level, substances appear in Tables 1 and 2 according to (i) the existence of a new registration under REACH (Table 1) and (ii) the existence of a notification (NONS) under the former chemicals legislation (Table 2), thus there are some duplicate entries at the substance level. However, the presence of an updated NONS dossier (Table 2 (c)) takes priority and removes the substance from Table 1.

Due to the fact that a substance can be phase-in or non phase-in depending on the specific market situation for an invidivual company, we have reported substances with this 'dual' status as phase-in substances.

EC Number Source Phase-in / Non phase-in status
2xx-xxx-x EINECS (European INventory of Existing
Commercial chemical Substances) List
Always Phase-in (Table 1)
3xx-xxx-x EINECS (European INventory of Existing
Commercial chemical Substances) List
Always Phase-in (Table 1)
4xx-xxx-x ELINCS (European LIst of Notified Chemical Substances) List Substances appear in Tables 1 and 2 according to (i) the existence of a new registration under REACH (Table 1)
and (ii) the existence of a notification (NONS) under the former chemicals legislation (Table 2), thus there can be duplicate entries.
However, the presence of NONS dossier which has been updated under REACH (Table 2 (c)) takes priority and removes the substance from Table 1.
5xx-xxx-x NLP (No-Longer Polymers) List Phase-in if one or more registrant(s) has declared the substance as phase-in. Indicated in Table 1 as non-phase in only in the case that all registrants have indicated a non-phase in status in their registration dossiers
List Number Source  

6xx-xxx-x

Automatically assigned, e.g. to pre-registrations of
substances with a CAS No.
Phase-in if one or more registrant(s) has declared the substance as phase-in. Indicated in Table 1 as non-phase in only in the case that all registrants have indicated a non-phase in status in their registration dossiers.

Additionally, priority is given to phase-in allocation for pre-registered substances.
7xx-xxx-x Assigned to substances after inquiries by the
ECHA Substance ID Team
Phase-in if one or more registrant(s) has declared the substance as phase-in. Indicated in Table 1 as non-phase in only in the case that all registrants have indicated a non-phase in status in their registration dossiers

8xx-xxx-x

Automatically assigned to substances identified only with a CAS No. (continuation of the 6xx-xxx-x series)

Phase-in if one or more registrant(s) has declared the substance as phase-in. Indicated in Table 1 as non-phase in only in the case that all registrants have indicated a non-phase in status in their registration dossiers.

Additionally, priority is given to phase-in allocation for pre-registered substances.

9xx-xxx-x Automatically assigned, e.g. to pre-registrations
without a CAS No. or other numerical identifier
Phase-in if one or more registrant(s) has declared the substance as phase-in. Indicated in Table 1 as non-phase in only in the case that all registrants have indicated a non-phase in status in their registration dossiers.

Additionally, priority is given to phase-in allocation for pre-registered substances.
