Last updated: April 2026 dataUS grade standards — No. 1 through No. 4 Yellow Dent — define several of the 10-digit tariff lines under this heading, alongside dedicated lines for certified organic Yellow Dent (1005902015), unpopped popcorn (1005904040, 1005904049), white corn (1005904055), and residual categories. Canada is the leading import source, with Argentina, Turkey, Brazil, and Peru also supplying the market. The grade-specific line structure means importers must present USDA or equivalent grading certificates to support the declared classification, particularly for premium No. 1 shipments.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The US schedule assigns separate tariff lines to Yellow Dent corn graded US No. 1 (1005902020), No. 2 (1005902030), No. 3 (1005902035), and No. 4 (1005902045), with a residual line for ungraded or other Yellow Dent corn. Importers must obtain official grade certificates — typically from a USDA-licensed grain inspection agency or an equivalent foreign authority — to substantiate the declared grade at entry.
Yes. Unpopped popcorn has its own dedicated lines (1005904040 and 1005904049) distinct from Yellow Dent and white corn lines. This matters commercially because popcorn is a distinct botanical type (Zea mays everta) with different end-use markets and pricing, and misclassifying it as generic corn could result in CBP penalties or post-entry audits. Importers should document variety and intended use.
