Petroleum Procedure: EN590 Diesel, Jet A1 and Crude Oil

Refined products and crude are sold by refiners, national oil companies and the major trading houses, almost always FOB or CIF with independent inspection and a letter of credit. The online "tank-to-tank" procedures that circulate in broker chains are not how this market works.
