We do understand from your advise to proceed IM8 like shipment 359. But for shipment 361 it is different because Import Request letter still not available and it is required for doing IM8 procedures. Until today, we asking CHK Thali for this document but still don’t have it.
Normal process is to show import request letter with shipping documents to customs and get duty&tax amount confirmation. Without this document, we cannot get confirmation of the amount but now we have requested customs to advise duty&tax by showing QR and invoice and assume import request letter will show same information. Below is the amount, 159,997 THB
