Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

A substance is identified as a PBT substance if it fulfils all three PBT criteria described above. None of these criteria are fulfilled, and therefore sulphur trioxide cannot be classified as PBT.
A substance is identified as a vPvB substance if it fulfils both vPvB criteria described above. The P and the B criterion are not fulfilled.
Sulphur trioxide is neither a PBT nor a vPvB substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
