ROLES IN SUPPLY CHAIN. During the registration of the substances in nanoparticulate state, the registrant could be assigned by different roles in the supply chain. Five choices in the NanoRegister platform give the possibility to the applicant to select his role. These choices include the “Distributor”, the “Importer”, the “Formulator”, the “Producer” and “Other”. Figure 21 shows the normalized quantity registered per role for the trade year 2018 and Figure 22 shows the distribution of the quantities per role. Based on the present analysis, several problems, indicated in bold were observed. Possible solutions to deal with these problems are suggested and, hereinafter indicated in blue color. The proposed adaptations for the optimization of the NanoRegister and for future data collection are indicated in black. Because this is a complex solution, in the future the system should foresee a possibility to update the data without creating a new registration number. We suggest to adapt the user interface of the database such that only data in one language can be entered (preferably English) or to work with language independent codes. We suggest to adapt the user interface of the database for example by foreseeing obligatory drop lists, such that generally more harmonized wording is used. We suggest not to make a distinction between agglomerates and aggregates for any of the parameters requested. We propose to foresee these additional information conditionally, depending on the input values e.g. no requirements for zeta potential, medium, pH value and ionic strength for powders, only for dispersions. In the new database, we interpreted the data case by case and we reformulated the input and wording, when possible. We suggest to require standardized descriptors in obligatory drop lists. Support should be provided to the applicants directing them to international standards and guidelines (ISO, OECD, CEN). These also foresee requirements for metadata and reporting. Provision of measurements uncertainties should be obligatory for specific parameters, in line with international standards and guidelines (ISO, OECD, CEN). Instructive sessions, presentations or webinars providing technical support on methodological issues can improve standardization and quality of the reported data and their uncertainties. We propose to implement a strict input format in the NanoRegister so the applicants can avoid erroneous introduction of registry numbers. For instance, a CAS registry number includes up to 1...
