I am in contact with customs department to get the certificate of origin. It will be released and signed by Polish Customs Authorities. I am not sure how long it will take but I will find out and let you know.
In terms of GMP Certificate - The company SYMBIOFARM is the factory where Essensival is manufactured. The producer is INVPOLAND who assigns Symbiofarm to manufacture Essensival. It means that GMP Certificate is released to Symbiofarm. In attachment there is Certificate of GMP issued by the company POLCARGO GROUP to Symbiofarm. Polcargo group is the authority who is allowed to make GMP certifiication. In the attached certificate there are signatures of Polcargo Group.
I can only send you the copy of the certificate - it means as it is in attachment. The manufacturer/ producer will not give me the original since they have only this one certificate for themselves. If that helps I can make certified translation of this certificate from Polish to English. From my other email I am also sending you presentation about Symbiofarm with some more information.
