I think we're maybe confusing new and existing substance regimes a little bit. For a new substance, the substance cannot be used until we say so. So there's no going back and saying now you have to take it off the market. You can't put it on the market until you've gone through this process. So that's the new substance regime.
For the existing substance regime, we are explicitly talking about things that are in use. When we say here are the rules, the limit in which you can omit it or use it, or when we say you can no longer use it, then we're absolutely imposing a new obligation on an existing industrial or commercial process or use. And in some cases we're requiring that activity to cease.
