Certified Corn (Maize) Seed, Excluding Sweet Corn

Chile's position as the top supplier reflects the counter-seasonal production strategy used by major US seed companies. Because Chile's growing season runs opposite to the US, seed companies can produce hybrid corn seed there during the Northern Hemisphere winter and import it in time for US spring planting. This arrangement allows a single growing cycle per year to be completed without waiting for the next US season.

Line 1005100010 covers yellow corn (maize) seed specifically, while 1005100090 covers all other certified corn seed excluding sweet corn — including white corn, blue corn, and other non-yellow field corn varieties. The color/variety distinction must be supported by the seed certification documentation accompanying the shipment. Consult a licensed customs broker or USDA APHIS regarding phytosanitary admissibility requirements before importing.
