Frequently Asked Questions
What are the major cost factors beyond the base price when importing other maize (corn) under HTS 100590?
Key additional costs include the U.S. Merchandise Processing Fee (MPF), which is 0.3464% of the entered value (minimum $34.64, maximum $649.23), and a variable Harbor Maintenance Fee (HMF) of 0.125% of the cargo's value if arriving by vessel. Furthermore, imports may be subject to a Section 232 tariff of 25% on the product's value if imported from most countries, significantly impacting total landed cost.
Does importing corn classified under HTS 100590 require an import license in the United States?
Yes, imports of corn under HTS 100590 generally require a USDA Phytosanitary Certificate to ensure it is free from plant pests and may be subject to quotas or tariff-rate quotas (TRQs). You must also ensure the corn is not genetically modified (GM) unless it complies with U.S. FDA and EPA regulations for GM crops.
What are the specific packaging requirements for shipping bulk maize (corn) under HTS 100590?
Bulk maize is typically shipped in dry, food-grade containers like 20- or 40-foot dry freight containers, or in bulk vessel holds. The packaging must prevent contamination and moisture, often requiring certified, fumigated, and pest-free conditions as per ISPM 15 for wooden materials. Proper ventilation and documentation proving the cargo's condition are critical to avoid spoilage and customs delays.
Seasonal Import Trends for Corn (Maize)
U.S. corn (maize) imports under HTS 100590 typically peak in the late summer and early fall (August-October), following the Southern Hemisphere harvests from key suppliers like Brazil and Argentina. There is often a secondary, smaller increase in volume during the spring (March-April). Import volumes can be lowest in the winter months (December-February) as Northern Hemisphere supplies are largely depleted and new harvests are not yet available. Monitoring these seasonal flows is crucial for logistics planning and price forecasting in the animal feed and milling industries.
Compliance Notes for Corn (Maize)
Corn classified under 1005.90 is subject to U.S. FDA Prior Notice requirements for food imports (FDA PN System). Shipments must also comply with the FDA's Foreign Supplier Verification Programs (FSVP) for human food. For corn intended for planting, an additional USDA PPQ Form 508 (Permit to Import Plants or Plant Products) and phytosanitary certificate are typically required. Be aware that the Lacey Act declarations apply if the product contains any amount of wood packaging material. Always verify the specific origin, as Maximum Residue Levels (MRLs) for pesticides and the presence of genetically modified organisms (GMOs) are key regulatory triggers that vary by country.
