Is this a true ISO 400 film? Or is it like so many

Is this a true ISO 400 film? Or is it like so many others and needs to be rated at 320 or even 200?
Asked by: Paul
Yes, most photographers treat the Ultrafine Xtreme UXF 400 Black and White Negative Film as a genuine ISO 400 film, not a film that universally needs to be exposed at 200 or 320.
