Every piece of Fuji I've ever bought has been made by TY. Only thing that I can think of is if they bought some slower speed CDRs that Fuji has outsourced to someone else.
Best way to tell is if you look down through the top of the package. The inner ring is clear if it isn't TY it's clear, opaque if it is TY. Also look to see if it's made in Japan.
There might be a chance that the person that didn't get TY got a hold of some counterfeit discs. It does happen on occasion depending where you live.
Unfortuntately they changed their packaging a bit, so it's harder to tell.
If you finalize, there's greater compatibility from a reading standpoint.
