If the value of the gift exceeds $100, you will be required to pay duty. If you have goods you intend to sell in the U.S., they will most likely be subject to duty, unless they are eligible for duty-free treatment under an international trade agreement (GSP, NAFTA, etc.).
Specialization of labor is a powerful force in an economy, benefiting small and large businesses alike. Workers produce more when they occupy specialized roles, so businesses can offer higher quality products at lower prices.
Adam Smith showed us long ago, and time continues to prove, that specialization of labor is productive, but specialization of labor ultimately involves specialized knowledge. The market decentralization in a firm is the result of the specialization of labor. The free market ideology of specialization of labor balanced by supply and demand law can presently be expressed in the setting up of a direct sourcing program.
