A : → We do not know which country you refer to regarding the issue of GSP Form A. In some countries it is possible to issue a back-to-back GSP Form A while others might have stricter rules. You can also have the freight forwarder as the shipper and/or the bank or its representative as the consignee, thus avoiding identities of both parties. Appended here is a link on the application of GSP Form A in China in which you would note in para. 3 on the amendment and re-issue of Form A in China, together with other details on the same subject.
Q : → Does anyone have an idea how it's possible for trader located in a third country to protect his secrecy of revealing the name of seller to buyer and buyer to seller on a GSP Form A. Can a GSP form be reissued by submitting the original one?
