After checking the information, this customer used to order first shipment of 266GA since Mar'15 And they can use them without any problem. But this time is the second shipment of this grade. After comparing among first and second shipment (problematic shipment), we found that the particle size of problematic shipment was bigger than the first shipment around 10 micron. PVC production has adjusted recipe to get less span of particle size distribution for serving main customers. It should be the caused of this case.
