Determining who should apply to ECHA and why
How to prepare and submit an inquiry (type 3) under REACh?

Since the end of the transitional registration period, you must ask ECHA whether a registration has already been submitted for the substance you wish to register (Article 26 of REACH). This is the case for a classic inquiry, i.e. if you are manufacturing or importing a new substance or a phase-in substance (existing substance) for the first time.

There are other specific situations for which an inquiry must be prepared. These are listed for your information at the end of the sheet.
