Joint submission and the sharing of information on substances should be provided for in
order to increase the efficiency of the registration system, to reduce costs and to reduce
testing on vertebrate animals. One of a group of multiple registrants should submit
information on behalf of the others according to rules which ensure that all the required
information is submitted, while allowing sharing of the costs burden. A registrant should
be able to submit information directly to the Agency in certain specified cases.
(34) Requirements for generation of information on substances should be tiered according to the
volumes of manufacture or importation of a substance, because these provide an indication
of the potential for exposure of man and the environment to the substances, and should be
described in detail. To reduce the possible impact on low volume substances, new
toxicological and ecotoxicological information should only be required for priority
substances between 1 and 10 tonnes. For other substances in that quantity range there
should be incentives to encourage manufacturers and importers to provide this information.
(35) The Member States, the Agency and all interested parties should take full account of the
results of the RIPs, in particular with regard to the registration of substances which occur
in nature.
(36) It is necessary to consider the application of Article 2(7)(a) and (b) and Annex XI to
substances derived from mineralogical processes and the review of Annexes IV and V
should fully take this into account.
