                                                                                                              (a) records to demonstrate that the industrial chemical does not consist of solid particles, in an unbound state or as an aggregate or agglomerate, where at least 50% (by number size distribution) of the particles have at least one external dimension in the nanoscale; or
                                                                                                              (b) the following:

                                                                                                              (ii) records of the basis on which the introducer believes that the industrial chemical does not consist of solid particles, in an unbound state or as an aggregate or agglomerate, where at least 50% (by number size distribution) of the particles have at least one external dimension in the nanoscale;
                                                                                                              (iii) records of the basis on which the introducer holds the belief mentioned in subparagraph (i)
