Problem with a production chemical

Problem with a production(Discharge Printing) chemical; we bought some pastes about 100 kg from our supplier.They gave that what we wanted and label said so.But while it opened it's found that proper chemical didn't come.You see, it's the time for production color making.In this moment this situation arises that means production will be hampered tremendously.

However today we sent those 5 buckets again to the suppliers and there also opened newer bucket and found same problem.i.e. label same ..........................................but chemical different.And without this chemical we can't continue production.
