Pls. find attached roll allocation list for welding rod.
From our record, there are 5 batches number have been shipped for this order. We did not see any unusual from our record.
Need your help to check the batch number or take photo of the label from those 3 rolls. The batch number should be included in the list. Then if possible, need to take the samples from the problem rolls send to the factory.
This will help us to analyze the root cause.
Again, I apologize for any inconvenience caused
