Substance Information

NB: Registration status and tonnage

  • The REACH Registered substance portal was updated on 9th November 2020; the REACH registered factsheets were further updated on 21st December 2020. Details of the improvements can be found at Dissemination Platform Updates. Reprocessing the entire dataset is ongoing since 21 December 2020. ECHA is making all possible efforts to synchronise the registration status and tonnage with the shortest delay.
  • While reprocessing is ongoing please note that substances whose registration dossiers are not yet processed can incorrectly state in the Infocard that they are not registered under REACH. In these cases if there is a link to a REACH registered substance factsheet then the substance IS registered. The correct total tonnage band can be found in the factsheet(s) for the substance.
