The Obama administration is announcing that it will allow Cuba's small private business sector to sell goods to the United States in a potentially important loosening of the half-century trade embargo on the communist island.

A list published by the U.S. State Department Friday says Americans will be allowed to import anything produced by Cuban entrepreneurs with the exception of food and agricultural products, alcohol, minerals, chemicals, textiles, machinery, vehicles, arms and ammunition.

The imports would have to be produced by a Cuban operating in one of the dozens of categories of private business allowed by the Cuban government. Most of the categories are for services like car maintenance or watch repair, not potentially exportable goods.
