You are 1000% correct in your description of MSDSs--they are not reliable. 
As you have said, there is no requirement that they tell the truth, the 
whole truth, and nothing but the truth.

However, some suppliers in fact do have reliable MSDSs.  DuPont comes to 
mind as an outstanding example.  Ashland Chemical is another.
