Verbatim doesn't 'make' anything anymore except Blu Ray, which they make in Singapore. Until recently they also made dual layer DVDs there too, but they may have stopped.
For most, if not all CD and DVD media, Verbatim sub-contracts or "outsources" their media production to at least 3 companies, Moser Baer India, CMC Magnetics and Prodisc, both in Taiwan.
For CDs, particularly in the U.S, "Verbatim" on the packaging could mean anything, but for DVDs, the vast majority are coded "MCC" or "MKM" and use the AZO dye, regardless of which subcontractor made them. Though there are some Taiyo Yudens and there are some 3rd rate products (e.g. own dye CMC MAG and MBI) sold in the developing world and in the West under the "Pearl White" line.
