There is not much "hassle" on your end. With Fedex and UPS there is an additional form in which you have to state contents and value (for tarrif/tax purposes to receiver, not shipper). I've not had any problems with sales (and purchases) to (from) HK, Singapore, Australia, NZ, UK and Canada. Shipping can be much more expensive and there may be weight limits, so check before you make a firm commitment. YMMV,
