If the delivery method is EXW, but the exporter actually helps to do the errands of FOB or FCA: first, domestic foreign exchange control, and second, the customer's export customs clearance can not be handled normally. Therefore, exporters are advised to choose the delivery method carefully, and FCA or FOB can ensure that exporters get the documents in time.

EX is the abbreviation of Exit (exit, passage, door exit), which stands for gate exit, and WORKS stands for factory. Ex-factory delivery is abbreviated as EXW. This is an international trade term, which refers to ex-works delivery. Refers to the completion of delivery when the seller hands over the goods to the buyer at his place or other designated place (such as workshop, factory or warehouse).
