U.S. imports of certified corn (maize) seed, excluding sweet corn (HS 100510) totaled $17.7M in April 2026, traded with 15 countries.
Last updated: April 2026 dataCertified field corn seed — split between yellow corn (1005100010) and other varieties (1005100090) — is a strategically significant import category because it supports the US seed industry's counter-seasonal production model: seed companies grow foundation and hybrid seed in the Southern Hemisphere during the US off-season and reimport it for domestic planting. Chile is the leading supplier for this reason, with Canada and France serving as additional sources for specific hybrid programs. USDA APHIS phytosanitary requirements apply, and seed lots must meet certification standards that align with the declared 10-digit line.

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.
