According to Sephora.com "Sephora.com ships to the contiguous 48 U.S. states, Alaska, Hawaii, Puerto Rico, and Canada. Shipping to other international destinations and U.S territories (such as Guam) is unavailable at this time."
I know there's a french Sephora site for Europe and a Chinese Sephora site for asia, so there might be a south america Sephora website. Otherwise I don't know. You have to look up the shipping policy of the specific site.
