If the raw material is commercially available, and if this raw material is the API only after purification, so we’re basically one step removed, does the raw material manufacturer fall under Q7A?

It sounds like you’re bringing an API into your facility and just further purifying it. Does Q7A
apply? Yes, because, basically, you’re bringing in the active ingredient in an unpurified form and
subjecting it to the purification. So, the manufacturer of the crude API would probably fall under
Q7A.
