Exporting Corn and Corn Derivatives to the US — US Ethanol and Starch Producers

Corn is the backbone of US industrial agriculture, serving as the primary feedstock for ethanol production and a key raw material for starch manufacturing. In 2023, the US consumed over 13.5 billion bushels of corn, with roughly 40% going to ethanol and another 10% to starch and sweeteners [1]. While the US is the world’s largest corn producer, domestic demand often outpaces supply in certain regions, and US ethanol and starch producers increasingly look to Latin America for reliable, cost-competitive imports of corn and corn derivatives such as dried distillers grains (DDGS), corn gluten feed, and modified starches. This page provides a comprehensive guide for suppliers and buyers navigating this high-volume trade corridor.

Product Specifications and Grades Relevant to US Buyers

US ethanol and starch producers require corn that meets specific quality parameters to ensure process efficiency and final product consistency. For whole corn, the primary grade determinants are test weight, moisture content, broken corn and foreign material (BCFM), and damage. The US Grain Inspection, Packers and Stockyards Administration (GIPSA) sets official standards: US No. 1 yellow corn must have a minimum test weight of 56 lb/bu, moisture no more than 15%, BCFM no more than 2%, and total damage no more than 3% [2]. For ethanol production, high starch content (typically above 70% dry basis) is critical for maximizing ethanol yield per bushel. Buyers also screen for mycotoxins such as aflatoxin and fumonisin, with maximum acceptable levels often set at 20 ppb for aflatoxin and 5 ppm for fumonisin in animal feed co-products.

Corn derivatives are traded under distinct specifications. DDGS, a co-product of dry-mill ethanol production, is valued for its protein content (minimum 26% crude protein), fat content (minimum 8%), and fiber. US buyers typically require DDGS to meet the American Feed Industry Association (AFIA) standards and be free of Salmonella and E. coli. Corn gluten feed (60% protein) and corn gluten meal (60% protein) are used in animal feed and industrial applications. Modified starches, including waxy maize starch and high-amylose starch, must conform to ASTM D445 for viscosity and AACC standards for purity. For starch producers, the key parameter is starch purity (minimum 99% on dry basis) and absence of protein residues, which can affect clarity and gelling properties.

LATAM and Africa Supplier Landscape for Corn and Corn Derivatives

Latin America is the primary source of US corn imports, with Brazil and Argentina leading as suppliers. Brazil exported over 35 million metric tons of corn in 2023, with a growing share destined for the US market [3]. Brazilian corn is predominantly yellow dent corn, well-suited for ethanol and starch production due to its high starch content. Argentina’s corn exports reached 34 million metric tons in 2023, with the US being a key buyer for both whole corn and DDGS. Paraguay and Uruguay also supply niche volumes, often offering premium quality with lower mycotoxin levels due to their drier climates. In Africa, South Africa is the largest corn producer, exporting about 2 million metric tons annually, though US buyers focus primarily on Latin American origins due to logistics costs and trade agreements.

For corn derivatives, Brazil is a major supplier of DDGS, driven by its expanding ethanol industry. Brazilian DDGS typically has higher protein content (28–30%) compared to US DDGS, making it attractive for premium feed blends. Argentina supplies corn gluten feed and meal, with significant production from its soybean-corn rotation regions. Colombia and Peru are emerging suppliers of modified starches, leveraging their native corn varieties such as cañahua and maíz morado for specialty starch markets. The US imported $1.2 billion worth of corn and corn derivatives from Latin America in 2022, with a 15% year-over-year increase [4].

US Buyer Types: Who Buys This, How They Procure, What Specs Matter

US ethanol and starch producers fall into three main categories: large integrated processors, mid-size regional plants, and specialty manufacturers. Large processors such as Archer Daniels Midland (ADM), Cargill, and POET operate multiple facilities and procure corn through futures contracts on the Chicago Board of Trade (CBOT) and direct purchase agreements. They prioritize consistent quality, reliable supply, and competitive pricing relative to CBOT No. 2 yellow corn futures. Mid-size plants, often farmer-owned cooperatives, buy corn locally but supplement with imports during supply gaps, focusing on moisture and BCFM specs. Specialty manufacturers producing organic or non-GMO ethanol require certified organic corn, typically from South America where organic production is expanding.

Procurement for starch producers is more spec-intensive. Modified starch buyers require viscosity profiles (e.g., 500–1000 cP at 6% solids), particle size distribution (95% passing through 100 mesh), and freeze-thaw stability. They often request samples for pilot testing before committing to contracts. Ethanol producers focus on starch yield, measured as ethanol conversion rate (gallons per bushel), with a target of 2.8 gallons/bushel for dry mills. Buyers also evaluate the co-product value of DDGS, which can offset feedstock costs. Contracts typically specify delivery FOB Gulf or CIF US Gulf ports, with payment terms of 30–60 days and quality arbitration per GIPSA rules.

Certifications and Import Requirements for Corn and Corn Derivatives

Importing corn and corn derivatives into the US requires compliance with USDA Animal and Plant Health Inspection Service (APHIS) regulations. For whole corn, shipments must be accompanied by a phytosanitary certificate from the exporting country’s plant protection organization, certifying freedom from quarantine pests such as the corn rootworm (Diabrotica virgifera) and the sugarcane borer (Diatraea saccharalis). The US also requires a fumigation certificate for bulk shipments to control stored grain pests. For corn derivatives, particularly those used in animal feed, the FDA’s Food Safety Modernization Act (FSMA) mandates that foreign suppliers implement preventive controls and that importers verify compliance through Foreign Supplier Verification Programs (FSVP) [5].

Certifications sought by US buyers include: Non-GMO Project Verification for non-GMO corn, USDA Organic certification for organic grades, and Kosher certification for starch used in food applications. For ethanol feedstock, the Renewable Fuel Standard (RFS) requires that imported corn used for ethanol production be verified as compliant with land-use change criteria, often through a third-party sustainability certification such as the Roundtable on Sustainable Biomaterials (RSB) or International Sustainability and Carbon Certification (ISCC). For DDGS, the AFIA’s Safe Feed/Safe Food certification is increasingly demanded by US feedlots. Tariff classification under HTS 1005.90.20 for corn and HTS 2303.10.00 for DDGS carries duty rates of 0.9% and 0.5% respectively under WTO commitments, but USMCA preferential rates may apply for Mexican and Canadian origins [6].

Pricing and Lead Time Context

Pricing for corn and corn derivatives is highly correlated with CBOT futures, but premiums and discounts apply based on quality, origin, and logistics. As of early 2025, CBOT corn futures hover around $4.50 per bushel, with Latin American corn typically trading at a discount of $0.10–$0.30 per bushel due to lower production costs and favorable exchange rates [7]. DDGS prices range from $160–$200 per metric ton FOB, depending on protein and fat content. Modified starches command higher premiums, with food-grade modified corn starch priced at $600–$900 per metric ton, depending on functionality and certification.

Lead times from Latin America to US Gulf ports are typically 10–14 days for bulk vessels from Brazil or Argentina, plus 5–7 days for customs clearance. For containerized shipments of specialty derivatives, lead times extend to 20–25 days due to consolidation and inland transport. Buyers often require at least 30 days’ notice for bulk contracts to arrange logistics and financing. Seasonality plays a role: Brazilian corn harvest runs February–May, while Argentina’s harvest is March–June, creating overlapping supply windows. US buyers adjust procurement timing to avoid peak domestic harvest periods (September–November) when local prices drop.
