U.S. imports of worked corn grains (hulled, pearled, sliced, or kibbled) (HS 110423) totaled $360K in April 2026, traded with 9 countries.
Last updated: April 2026 dataMechanically processed corn kernels — hulled, pearled, sliced, or kibbled — enter the US under a single tariff line (1104230000), distinct from corn flour, meal, or starch. These forms are used in snack manufacturing, brewing adjuncts, and specialty food applications where whole-kernel texture is preserved after processing. Canada leads US imports under this heading, with Peru and Brazil also serving as notable sources. Because these are food-grade grain products, FDA prior notice and FSMA foreign supplier verification requirements apply at entry; classification agents should also confirm the product is not more appropriately classified as hominy or grits under a different heading.

Worked corn grains under 1104230000 are kernels that have been hulled, pearled, sliced, or kibbled but retain a recognizable grain structure. Corn grits and hominy are typically classified elsewhere — grits under heading 1102 or 1904 depending on further processing, and hominy under heading 1102 or 2302. The key classification question is whether the kernel's structural integrity is maintained and whether any further cooking or chemical treatment (e.g., nixtamalization) has occurred. Consulting a licensed customs broker is advisable for borderline cases.
All four processing methods — hulling, pearling, slicing, and kibbling — are captured within the single 10-digit line 1104230000, so the duty rate does not vary by method within this heading. However, if the processing goes further (e.g., cooking or puffing), the product may shift to a different heading with a different rate structure.
