Check the third party invoice of the company in Thailand for

Hello, we would like to directly ask you to help us to apply for Thailand form e certificate of origin, because in front of us is the agency that our freight forwarder helped to find. We communicate with the freight forwarder, and the freight forwarder communicates with the agency. The three-party communication is too troublesome. And now we have a more difficult problem. The shipper of our bill of lading shows the mainland company. The form e certificate of origin that we ask your agent to handle can only show our title under the description of the goods. Now the guests also ask to tick the third party invoice. The agent we used to find said that the domestic company can't check the third party invoice. Please ask Thailand form E. can you make out the invoice of the third party with the description of the goods in column 7 of the certificate of origin showing the domestic company? Do you often do the form e certificate of origin in Thailand recently? All the customers can clear the customs smoothly. We hope our customers can have a smooth customs clearance this time. There will be more orders in the future, because the first time you do this certificate of origin, I'm afraid of any problems in customs clearance.
