/12/16 In an earlier communication, you indicated the customer's standard lot was the same as the complaint lot? Can you verify this? Our senior Manager of QA indicates that the Standard lot should not be the same as he lot being compared. The only picture sent to us for the investigation was that of 3 samples of powder on a white surface and against a mirror. Did the customer do drawdowns to compare or just a color comparison of the powder samples?
1/12/16 Hello Sutachinee,
I have passed your request for the drawdowns on to our Quality team to see if this is possible. Meanwhile, please respond back as to what specifically your customer was finding unacceptable with this batch. Does the customer consider the batch to be lighter, darker, more yellow, more or less red? Our testing as reported to you in December has determined this batch is in specification, so we are interested in what your customer is indicating.
regards,
Bob
