Analysis
HTS 1102.20.00 covers corn (maize) flour under heading 1102 (cereal flours other than of wheat or meslin).
The general rate is 0.3¢/kg, a specific or compound duty rather than a simple percentage, so the effective burden depends on the unit value of the goods: cheap goods pay proportionally more than expensive ones. Importers usually convert it to an ad valorem equivalent to compare it with other lines.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 0.3¢/kg. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
Census statistics map these goods to NAICS 311211 (Flour Milling), an industry of 333 US establishments employing 14,916 people. That is the industry code a US manufacturer of the same product would normally use.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of 0.3¢/kg.
