Differences in responsibilities and risks: In EXW, the seller has the least responsibility. In FOB, the seller has moderate responsibility. In CIF, the seller has the greatest responsibility, not only responsible for delivery at the port of shipment, but also for freight and insurance etc..

CIF is one of the international trade terms, and its full name is Cost, Insurance, and Freight, which means "cost, insurance and freight". Under this term, the seller is responsible for all costs of transporting the goods to the designated port of destination.
