Ziad K. Abdelnour, President & CEO Blackhawk Partners, Inc, the New York_based advisory firm on such matters, puts it this way: "Giving a Letter of Intent only means 'Yes I'm intent to buy the goods but I can change my mind anytime.' A letter of Intent is not a binding contract. [Hence] The Letter of Intent is a total waste of time on a worthless piece of paper."
Traders are better off NOT using documents like LOI, ICPO, FCO, etc. Even if and when they rarely are used in internal trades, on a restricted level within specific industries, they have no legal or customary basis in International Trade whatsoever. In fact the presence of many of these terms are considered to be signs of Advance Fee Fraud, by knowledgeable players and law enforcement.
