of 17 June 2021

amending Annexes VII to XI to Regulation (EC) No 1907/2006 of the European Parliament and of the Council concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), establishing a European Chemicals Agency, amending Directive 1999/45/EC and repealing Council Regulation (EEC) No 793/93 and Commission Regulation (EC) No 1488/94 as well as Council Directive 76/769/EEC and Commission Directives 91/155/EEC, 93/67/EEC, 93/105/EC and 2000/21/EC (1), and in particular Article 131 thereof,

Whereas:

| (1) | Regulation (EC) No 1907/2006 imposes specific registration duties and obligations on manufacturers, importers and downstream users with a view to generate data on substances they manufacture, import or use, to assess the risks related to those substances and to develop and recommend appropriate risk management measures. |

Regulation (EC) No 1907/2006 imposes specific registration duties and obligations on manufacturers, importers and downstream users with a view to generate data on substances they manufacture, import or use, to assess the risks related to those substances and to develop and recommend appropriate risk management measures.

| (2) | Annexes VII to X to Regulation (EC) No 1907/2006 set out standard information requirements for substances manufactured or imported in quantities of 1 tonne or more, 10 tonnes or more, 100 tonnes or more and 1 000 tonnes or more, respectively. Annex XI to that Regulation sets out the general rules for adaptation of the standard testing regime set out in Annexes VII to X thereto. |

Annexes VII to X to Regulation (EC) No 1907/2006 set out standard information requirements for substances manufactured or imported in quantities of 1 tonne or more, 10 tonnes or more, 100 tonnes or more and 1 000 tonnes or more, respectively. Annex XI to that Regulation sets out the general rules for adaptation of the standard testing regime set out in Annexes VII to X thereto.

| (3) | In June 2019 the Commission and the European Chemicals Agency (‘the Agency’) concluded in REACH Evaluation Joint Action Plan (2) that certain provisions in the Annexes to Regulation (EC) No 1907/2006 should be amended to provide more clarity on the obligations of registrants and on the role and responsibilities of the Agency under Titles II and VI of that Regulation, respectively. |

| (4) | Experience has shown that the introductory texts of Annexes VII to X to Regulation (EC) No 1907/2006 are insufficient and that additional requirements should be introduced for human health and environmental purposes as regards the chosen study design where a test method offers flexibility. This should, among others, ensure that animal testing is performed at appropriately high dose levels. |

| (9) | The provisions on toxicological information in Annex IX to Regulation (EC) No 1907/2006 require certain clarifications on when the sub-chronic toxicity study does not need to be conducted. In addition, it is necessary to amend the specific rules laid down in Annexes IX and X to Regulation (EC) No 1907/2006 about adaptation for the reproductive toxicity studies in order to better specify the cases where testing does not need to be conducted. It should also be clarified how to demonstrate low toxicological activity of a substance in order to adapt testing. Finally, the provision setting out the conditions under which no further testing is necessary for sexual function and fertility or developmental toxicity should be simplified. |
