Unless they specifically say that they don't, then they all contain potash. This is, simply, a word that means any potassium salt in a fertilizer.
You can confirm this by checking the ingredients for potassium based salts. The middle NPK number will indicate how much potassium is present, and will indicate that there are potassium salts.
