Hi Dr Freeman,
I can't actually email the documents to customs because I do not have any of the documents they're asking for. Everything like invoice, detailed descriptions, etc that they want, I would expect to be included in the parcel. I've emailed Mesochem asking them to confirm the paperwork was included, or to send me copies of it, but I'm not sure what else I can do.
I see from Emilio's Fedex number above that his order arrived at customs at 8.07 AM Friday and was cleared immediately (at 8.07 AM). My identical order arrived 4 hours later (at 11.43 AM Friday) and they're still holding it. That's the luck of the draw, I guess.
