Maize exports is the amount of metric tons of maize leaving a country's borders in a given year. The data comes from governments most frequently through FAO questionnaires, though also through magnetic tapes and national publications. Import and export data is reported in terms of either general trade (recorded when entering or leaving the country's borders) or special trade (recorded when cleared through customs for home use or export).
