Définition
Фоб
I
(от греч. phóbos - страх, боязнь)
часть сложных слов, означающая боящийся, враждебный, ненавидящий, например женофоб.
II
(англ. fob, сокр. от free on board - Франко борт, буквально - свободно на борту судна)
вид купли-продажи (См. Купля-продажа) товаров при морской перевозке. Условия Ф. означают, что продавец обязан доставить товар в порт и погрузить на указанное покупателем судно; расходы по доставке товара на борт судна включаются в стоимость товара. В некоторых портах при поставках на условиях Ф. расходы по погрузке несёт покупатель. Риск случайной гибели имущества или его повреждения возлагается на продавца - до момента пересечения товаром борта судна, и на покупателя - с указанного момента. По Общим условиям СЭВ (См. Общие условия СЭВ) право собственности на товар переходит от продавца к покупателю одновременно с переходом риска. См. также Фас.
