Commodity is a term applicable to any substance which is traded by the MT (with the exception of Iagreous Fuel which can be traded by the kg). The buy and sell value of a given commodity in CR per MT is up to the individual or government organization selling it. Exploiting the disparities between buy and sell prices in different locations by trading large quantities of materials is a lucrative way of making money on Vieneo.
Please note that some commodities exist (and can be traded) in refined and unrefined states.
Some commodities are naturally found on Vieneo and some of them are manufactured.
