No it doesn't. You might, and another said it was "almost guaranteed"; however, I checked today with a regional supervisor I know in Miami. The duty IS owing. Apparently, it matters though through which customs airport/ region it passes through. Once Fed ex bought out the smaller forwarders, there has continued to exist a problem with enforcement. They don't screen through Miami, maybe the priorities are in other areas. This is a big issue with watch purchasers in the states.
As an aside- I checked with two Vass providers ( middlemen, proxies, nice guys etc...) . yes, on a RTW, the price is slightly higer than Meermin, and therefore a better value for many ( especially with lasted trees)
On MTO, they are MUCH higher. Am leaving this one alone, isn't worth the disagreement.
EMS is the safest router as mentioned by another for a sure non levied duty on purchase from Europe
