In the section "guidelines and other information" you will find more background information and support for each of the procedures mentioned.
For some subjects, there are shared responsibilities with other government departments. Often, they also have their own helpdesk for specific questions about this.

If you have complex questions about your obligations under REACH, CLP, PIC or BPR, you can in the second place always consult the helpdesk of the European Chemicals Agency (ECHA).
