There are four distinct steps to exporting rice.  The first step to exporting rice is to determine EXACTLY what and HOW MUCH you intend to export, whether you are functioning as an agent or a broker.  In the U.S., the standard rice unit is traded as a U.S. grade 2.  In order to determine what your rice equivalent grade is please visit the USDA website and compare their grades to your needs to determine which type is right for you.  Most suppliers will not provide an export quote unless you have established what you are looking for in domestic units.  Once you have established the type and quantity you must then determine your method of payment and locate a supplier.  Methods of payment vary widely, but the most commonly used is a Letter of Credit.  Letters of Credit are issued by banks specializing in international trade and are acceptable to most suppliers.  In order to locate the required volume and after having determined your method of payment, you should search the supplier directories that can be found on industry trade association websites and contact their offices.  Very rarely do producers actually contract directly with exporters.  After locating a supplier that is willing and able to meet your needs as an exporter the remaining step requires you to then arrange transportation from the delivery point to your point of departure, ensure that all of the sanitary/phytosanitary requirements for your country of destination are met, ensure that all proper documentation is accounted for in order for the shipment to leave the country, and must also arrange international transportation for the product.
