What is HS 100590?
HS 100590 covers non-seed maize, commonly traded as feed corn or yellow maize, and is classified under Chapter 10 of the Harmonized System (Cereals). The "non-seed" distinction is critical at the classification stage: maize intended for planting falls under HS 100510, while HS 100590 captures all other maize, including commodity-grade grain destined for industrial and agricultural end uses.
Primary end markets include animal feed (the dominant application globally), ethanol and biofuel production, wet milling for starch and sweeteners, aquaculture feed, and general food processing. Given its role as a feedstock in both the livestock and energy sectors, demand for HS 100590 is structurally linked to crude oil prices, livestock herd cycles, and government-mandated blending targets in markets such as the US, Brazil, and the EU.
Top Sourcing Countries for Feed Corn / Yellow Maize
Four countries account for over 76% of global HS 100590 export flows, giving the market a medium supply concentration profile with meaningful optionality for diversified sourcing strategies.
- United States (25.3% share, 127 markets): The US maintains the broadest market reach of any single exporter and is the primary origin for major importers including Japan ($2.96B in 2024 customs flows), Mexico ($1.78B), and Colombia ($1.53B). CBOT futures pricing on the CME anchors US corn to transparent global benchmarks, making it the default reference origin for trade finance and contract structuring.
- Brazil (19.7% share, 114 markets): Brazil has rapidly expanded its second-crop (safrinha) corn output and is now a structurally competitive alternative to the US, particularly for Egypt ($1.10B), Vietnam ($936M), and Iran ($923M). Brazilian corn is typically cost-competitive on freight to Asian and Middle Eastern markets during its harvest window (June–August).
- Argentina (17.1% share, 109 markets): Argentina is the primary supplier to Vietnam ($1.38B), reflecting its freight advantage into Southeast Asia. Export tax regimes and FX policy in Argentina introduce periodic supply unpredictability, but origin pricing is often materially lower than US equivalents on a CFR basis.
- Ukraine (14.4% share, 62 markets): Ukraine remains a significant Black Sea exporter, supplying China ($1.11B in 2024 flows) and EU-adjacent markets. Ongoing conflict-related logistics risk constrains its market reach relative to pre-2022 volumes, but Black Sea corridor activity has partially stabilised. Buyers should apply elevated force majeure and cargo insurance provisions when sourcing from this origin.
- France, South Africa, Poland, Myanmar serve as regional or niche suppliers, with France and Poland relevant for EU-compliant, non-GMO certified volumes and South Africa covering sub-Saharan and Indian Ocean demand.
Import Duty Rates and Trade Agreements
Duty exposure on HS 100590 varies significantly by destination. India applies a 50% MFN tariff on maize imports, making it one of the most protected markets globally and effectively pricing out most import activity outside of severe domestic shortfalls. Procurement teams targeting the Indian market should monitor government notifications on duty suspensions, which are periodically issued during domestic supply crunches.
Key importing markets such as Japan, South Korea, Mexico, and Egypt maintain lower or zero MFN rates under bilateral or multilateral agreements, and several benefit from preferential access arrangements with the US (USMCA for Mexico) or Brazil. Verifying the applicable duty rate, including any safeguard or anti-dumping provisions, against the destination country's current tariff schedule is essential before finalising landed cost calculations.
Cost Drivers and Price Outlook
CBOT/CME corn futures remain the primary global pricing benchmark and should be monitored as the baseline for contract negotiation. Key variables currently influencing the price environment include:
- Crude oil linkage: With Brent crude trading near $69.41/BBL (up 7.4% MoM as of February 2026 data), ethanol demand from the US corn belt remains supported, tightening domestic corn availability and applying upward pressure on export prices.
- US and Brazil harvest yields: Seasonal production cycles in both origins create predictable supply windows. Buyers should time procurement or forward contracts to capture post-harvest price softness in July–September for Brazil and October–December for the US.
- El Niño/La Niña cycles: Weather pattern shifts directly impact yield outcomes in South America and southern Africa. Active monitoring of NOAA and USDA WASDE reports is standard practice for professional buyers.
- USD exchange rate: As a USD-denominated commodity, a weaker dollar increases purchasing power for non-USD importers and often stimulates demand from Egypt, Southeast Asia, and Latin America.
- Black Sea disruption: Ukrainian supply constraints continue to redirect volumes to Brazilian and Argentine origins, supporting FOB premiums in those markets.
Compliance and Sourcing Considerations
GMO compliance is the primary regulatory risk for HS 100590 trade. The EU, China, and several other markets require country of origin certification and biotech trait event approval prior to import. Shipments containing unapproved GMO events can be detained or rejected at destination, with significant demurrage and disposal costs. Buyers sourcing US or Argentine corn for EU or Chinese delivery must verify that the specific hybrid varieties in the cargo hold valid import approvals in the destination market.
Transshipment risk for this commodity is rated medium. Yellow maize is commonly consolidated or transshipped through regional hubs, which can complicate certificate of origin traceability. Customs agents should ensure bills of lading and phytosanitary certificates clearly reflect the true country of production, not the port of loading. Fumigation and moisture certification requirements vary by destination and should be confirmed with the destination country's national plant protection authority before shipment.
How to Source Feed Corn / Yellow Maize Efficiently
Effective procurement of HS 100590 requires aligning origin selection with your delivery window, end-use specification, and compliance obligations. Practical steps include:
- Benchmark CFR landed costs from at least two of the four major origins (US, Brazil, Argentina, Ukraine) before committing to a single supplier corridor.
- Confirm GMO event approval status for your specific destination market before origin selection, not after contract signing.
- Use CBOT futures curves to assess whether forward pricing or spot procurement is more advantageous given current carry structure.
- Verify phytosanitary, fumigation, and moisture content requirements with the importing country's authorities, as these affect freight and insurance cost components.
- For India-destined volumes, check the current duty notification status before budgeting — the 50% MFN rate can make imports economically unviable without a duty suspension order in place.
- Assess transshipment exposure in your supply chain and ensure certificate of origin documentation is traceable to the country of production, not the load port.
