1.  The supplier shall assemble and keep available all the information used by that supplier for the purposes of classification and labelling under this Regulation for a period of at least 10 years after the substance or the mixture was last supplied by that supplier.
The supplier shall keep this information together with the information required in Article 36 of Regulation (EC) No 1907/2006.

3.  The competent authority or the enforcement authorities of a Member State in which a supplier is established or the Agency may require the supplier to submit to it any information referred to in the first subparagraph of paragraph 1.
However, where that information is available to the Agency as part of a registration pursuant to Regulation (EC) No 1907/2006 or a notification pursuant to Article 40 of this Regulation, the Agency shall use that information and the authority shall address itself to the Agency.
