There are two alternatives to ship items to Ushuaia (we havent had opportunity to try any of them).
Option 1: Ship items to the care of Agunsa in Punta Arenas, Chile (see the instructions on the Punta Arenas Shipping section). They will do the paperwork and work with the Argentinean agent (SeaLand) to get the item expedited from Punta Arenas to Ushuaia.
Option 2: Contact Delver Agents (offices in Seattle, WA), they work with SeaLand in Ushuaia. They, allegedly, can get a package from their ware house in Miami to Ushuaia in 3-4 business days.

NOTE: Customs in Argentina tends to be very complicated. It is important that the paperwork be complete, and ideally cleared with SeaLand and Delver ahead of time (so that they can run it by Argentinean customs).
