The electricity supply in my area is also 220V. I have purchased and used a number of after the market power cord made in US with no problem. The only thing you need to concern yourself is that your property insurance company may deem it as using some sort of non-standard wiring. In my area I sometimes see the dealers having those US cords marked as "For Export Only" to avoid possible legal infrigement issue. Can't say if this will apply to your country however.
