Hey there all you knowledgeable folks!

I urgently need help with the calculation of the FOB price on agricultural products. I found a bunch of sites on google, but nothing that really helps.
I am busy with market research on Soybeans and Soybean oil & cake and need to know the following:

1. What makes up the FOB price?, and
2. Where can I find the values for all the costs that goes into FOB price calculation?

Any help will be greatly appreciated.
