The meaning of CNF in import and export is cost and freight. However, CNF is widely replaced by CFR as the accepted abbreviation for cost and freight.
Cost and freight is a pricing term in international trading. It means the stated price for merchandise includes the cost of the merchandise, its transportation to a seaport and its shipment to the port of destination. A quotation with a CNF or CFR price always includes the port of destination. This type of pricing does not include insurance, which is the buyer's responsibility. Additional pricing terms are CIF, which includes cost, insurance and freight and FOB (freight on board), which includes all transportation costs incurred until the merchandise is loaded on a ship.
