Shure aren't allowing authorised distributors to ship outside of the US, only locallly.
Flavio_T has said as much, there's a thread about it here.

The same rules apply to all authorised distributors, including DiscountedHeadphones, which is Paul @ iDealSound.
There are ways around this if you have friends or relatives in the USA, but direct shipping will only be undertaken by non-authorised dealers, and you'll void your warranty that way, which isn't really worth it on a pair of cans this expensive, if you ask me.
Still, you pays your money and you takes your choice. Just thought I'd point out a few things worth knowing.
