three friends that mentioned information are correct, but one thing that I found in your question that you are a trading company - a middle man trader - there is a misunderstanding that you are not the factory, term of FOB may not be applicable to the factory. Buyer in overseas placed order to you on FOB, normally your order to factory should also back-to-back to the factory, otherwise it doesn't apply if you buy goods from factory is ex factory price.
