The sheet tells you its 4.9% phosphate pH 7. I would nomally use mM when talking about buffer concentration though

Not enough data.
It is probably a buffer containing NaH2PO4 and Na2HPO4 (about 0.35 to 0.40 mol in total). Due to the troublesome dissolution of Na2HPO4, the buffer is probably prepared by partially neutralizing NaH2PO4 with NaOH. The rest is the secret of the manufacturer.
