About FOB (please have the experience of this expert advice, thank you very much) very urgent! If the answer is complete and thoughtful I will add points.

1. Your formula is basically correct, is to see what is included. All the costs before the offshore contains goods sent to the port before the customs clearance, transportation, and port charges and so on. And the total price of the product should also include your own profit. This price is of course the other side to pay, who buys goods who pays.

2. FOB case is generally the customer designated freight forwarder, the freight forwarder should take the initiative to contact you to understand the production progress of your goods, and compare your production progress and the importer of the scheduled shipment between the gap, is to see if you can catch up with the ship. If the production of your goods is slower than expected, he will also take the initiative to inform the importer.

3. In terms of payment, if you use T/T, will he pay before you deliver the goods or after? If you deliver the goods, the other party does not pay and how? After all, it is the other party's designated agent, you will have some risk.

Whether or not the other party accepts it is also a question of the order of payment. Between you to see who can bear this risk.
