Below is a location map of where you can ship to from Nicaragua.  The United States is 2 hours by plane and 3 days by sea.  I have written about Nicaragua's ports in the past and this map illustrates the ease of shipping from them. The is also a link from that one that shows all of the flight times for coming into the country.  Some tax benefits are as follows:

• 100% income tax exemption.
• 100% exemption on import taxes for machinery, equipment, and intermediate goods as well as transportation or support services for the free zone.
• 100% exemption on municipal taxes.
• 100% value added tax (VAT) exemption.
• 100% capital gains and property tax exemption.
• Unrestricted repatriation of capital.
