Title: likely explanation

The MSDS probably reflects the concentration of phosphoric acid used in the manufacturing process, but as they also have added water, the retail product is more dilute.

To be really sure about the concentration, measure the density, and compare it to 85% H3PO4 as well as H2O, and if the conc/density curve is linear, you can deduce the acid % from that.
