Goods are “produced for commerce” if they are “produced, manufactured, mined, handled or in any other manner worked on” in any State for sale, trade, transportation, transmission, shipment or delivery, to any place outside thereof. Goods are produced for commerce where the producer intends, hopes, expects, or has reason to believe that the goods or any unsegregated part of them will move (in the same or in an altered form or as a part or ingredient of other goods) in interstate or foreign commerce. If such movement of the goods in commerce can reasonably be anticipated by the producer when the goods are produced, it makes no difference whether he himself or the person to whom the goods are transferred puts the goods in interstate or foreign commerce. The fact that goods do move in interstate or foreign commerce is strong evidence that the producer intended, hoped, expected, or had reason to believe that they would so move. Goods produced to serve the movement of interstate commerce within the same State are also produced for commerce within the meaning of the Act, as explained in part 776 of this chapter.
