It means, literally, "free on board". Translated to ordinary English, it means that if someone sells you a product FOB their plant, you pay freight. On the other hand, if they sell it to you FOB delivered, they pay the freight.
In a past life I worked in the steel industry, where products were typically sold by the truckload, and FOB was an everyday term.
Thanks Ed!
From what I have read, UPS handles everything from the shipper to your door. They are customs brokers. Haven't got any quotes for overseas yet.
What does it matter if by air or sea? Cost?
