Nowadays, to hear many of the oil sellers and operators, particularly their brokers and agents, who are involved in the international open market crude selling, describe it, this document _ called the "Letter of Intent" or LOI, for short _ is not only an essential document for doing crude oil business, but one which every credible person or company engaged in crude buying should always use in initiating a purchase. To many of these operators, not only should crude oil buyers use the LOI to initiate their buying orders, but initiating the purchase order in that manner, they say, has always been the usual way by which credible buyers initiate their purchasing projects, as doing it that way indicates, they claim, that a buyer is "serious" and genuinely committed to making a purchase.
LOI is used as manipulation tool at the hands of unscrupulous sellers & agents. Often times, obscure or scam_oriented persons who claim to be crude Sellers, or represent themselves as sellers' agents, mandates or brokers largely by an Internet contact or communication, employ the LOI merely as a tool to quickly "corner and box in" a prospective buyer to a purchase deal, before the prospective buyer may demand that they provide their business profile or show him something tangible to demonstrate that they are truly legitimate sellers. Such sellers would persistently demand that the prospective buyers hurry and issue them an LOI right upfront purportedly as proof that they are "serious" about making the purchase _ that is, before the buyer may probably start raising some probing questions about them or their credentials as legitimate sellers.
