Freight on board (FOB) is a term that refers to a shipping agreement between a buyer and a seller. It represents the point where the buyer takes responsibility of the goods and means of transportation. There are a number of synonyms for FOB, each with their own nuances and implications. These include free carrier, cost and freight, cost, insurance, and freight, delivered at place, and ex-works. While these terms may differ slightly in their meaning and context, they all relate to the transfer of goods from seller to buyer, and the associated costs and risks. Ultimately, choosing the right shipping agreement depends on the specific needs of both parties involved in the transaction.
