Greetings, This is not Visa related, Covid or the like. My fiance' in Sriracha is trying to mail me by Fed Ex a package of 5 bottles of the Mae Mali oil to the USA. The currier is telling her it is a controlled substance and requires a FDA request (in her words). She wrote it down as a gift as "essential oils" on the commercial invoice but the guy at Fed Ex tells her she needs the manufacturer's certificate and FDA request? How can we get it by them?
