In a large bowl combine confectioners sugar with coconut and condensed milk.
Shape the mixture into 1-inch balls and place onto a pan lined with wax paper. Place in refrigerator until firm.
In a microwave-safe glass bowl, melt the chocolate chips with shortening, removing to stir once or twice until smooth.
Dip each ball into the chocolate allowing the excess chocolate to drip off. Place the chocolate balls onto the waxed paper; let stand until set. Store in refrigerator.
