We found the TGA in HGA inventory that marking "IPTUS" and "IPTTH". What's different between "IPT-US" and "IPT-TH"? Only a separate site to build IPT between US and Thailand, right? Currently, we use the MPT TGA under marking "ECR0178683". I'm not sure that we can mix them in with our current MPT TGAs or can't use them.
