@Stony This is indeed an existing shortcoming in the current system.
For various (tax?) reasons we cannot order a model with payment account in country A, and then have it ship to country B.
(dropshipping it is called I think?)
I have run into this a few times.
As to import duties in India, I have no idea
I personally have not kept track of specific countries, but it seems Canada is the one of the most troublesome with import+carrier fees.
I have seen happy NZ and Australians customers, so region of the world is not really of much influence (except in Initial shipping cost)
It just seems to come down to local taxes/duties and UPS rates.
This is not specific to Shapeways, so perhaps call your local UPS office and ask them which duties and taxes could apply?
But yes ordering it yourself first and then ship on is bothersome.
Cheers,
