Nah, a shipment of gw's would have priority shipping I think. It isn't just one unit, it is a lot of time sensitive carts, worth a lot of money. Also, the less time it's in the air, the less chance of it getting caught in customs I think(correct me if I'm wrong.)
Where I worked before, we did international shipping to/from china of our product. (not illegal product mind you but that's not relevant to my story.)
We'd ship 6 figures worth of product and it would still take quite a while. Mainly with getting stuff into China though. Getting stuff out was slow but not AS slow.
**edit.
"Overnight" into china took around 1.5 weeks. (it felt like infinite days and tracking information was pretty much non-existent. UPS said delivered but it definitely wasn't.)
"Overnight" out of china took about 1 week. (4ish business days.)
