Thanks, this is exactly the reason. We may still have MSDS version with ROHM and HAAS LLC as manufacturer, but it must be stored in some body’s personal folder. So for GAA from Singapore, we still can apply the old MSDS, but when we change to USA source, the public version we can download is changing manufacture name though they are totally same in physically.
Since we don’t check MSDS change until we have any needs, we won’t realize there is a change while physically there is nothing changed.
