Exporting Urea and Ammonium Nitrate to the US — US Ag Distributors and Co-ops

Urea and ammonium nitrate (UAN) are the backbone of nitrogen fertilization in US agriculture, supplying over half of the nitrogen used on corn, wheat, and other row crops. For US ag distributors and co-ops, securing reliable, cost-effective imports of these fertilizers is critical to managing input costs and ensuring timely spring and fall applications. Latin America, with its abundant natural gas reserves and growing production capacity, has emerged as a key source for granular urea and ammonium nitrate solutions, offering competitive pricing and logistical advantages over traditional suppliers from the Middle East and Russia. This page provides a comprehensive guide for US buyers—from distributors to purchasing cooperatives—on sourcing urea and ammonium nitrate from Latin America, including specifications, supplier landscapes, certifications, and pricing context, with actionable insights from Coppermont's trade advisory team.

Product Specifications and Grades Relevant to US Buyers

Urea (46-0-0) is the most concentrated dry nitrogen fertilizer, typically supplied as white, free-flowing prills or granules with a minimum 46% nitrogen content. US buyers require urea that meets ASTM D7310 standards for fertilizer-grade urea, which specifies a biuret content of no more than 1.0% to avoid crop damage, a moisture content below 0.5%, and a particle size distribution of 90% passing through a 2.0–4.0 mm sieve [1]. For liquid applications, urea can be dissolved into urea ammonium nitrate (UAN) solutions, typically at 28% or 32% nitrogen concentrations, but this page focuses on solid urea and ammonium nitrate.

Ammonium nitrate (34-0-0) is another high-analysis nitrogen source, valued for its rapid availability to crops and lower volatility compared to urea. US specifications for agricultural-grade ammonium nitrate require a minimum 33.5% nitrogen content, with less than 1.0% moisture and a particle size that passes through a 1.0–3.4 mm sieve. The product must also meet US Department of Transportation (DOT) regulations for oxidizing solids, which impose strict packaging and labeling requirements for transport and storage [2]. Both urea and ammonium nitrate are subject to US Environmental Protection Agency (EPA) registration as fertilizers, requiring that imported lots be labeled with guaranteed analysis and manufacturer information.

LATAM and Africa Supplier Landscape

Latin America is a major producer and exporter of nitrogen fertilizers, driven by low-cost natural gas feedstocks in countries like Trinidad and Tobago, Venezuela, and Mexico. Trinidad and Tobago, with its petrochemical complex at Point Lisas, is the largest urea exporter in the region, shipping over 4 million metric tons annually to the US and other markets [3]. Brazilian producers, such as Petrobras and Yara Brasil, also supply urea from plants in Bahia and Sergipe, though domestic demand limits export availability. In Africa, Nigeria and Egypt are significant producers, with Nigeria’s Indorama Eleme Petrochemicals exporting urea to the US under the African Growth and Opportunity Act (AGOA), which provides duty-free access for certain products [4]. However, supply from Africa is often subject to logistical bottlenecks at ports and higher freight costs to the US Gulf Coast, making Latin American suppliers more competitive for US buyers.

Supplier reliability is a key concern for US distributors and co-ops, who require consistent quality and on-time delivery during peak application windows. Latin American producers typically offer contractual terms with penalties for quality deviations, and many have US-based agents or warehouses to facilitate logistics. For ammonium nitrate, supply is more limited, with major producers in the US (such as CF Industries and Nutrien) dominating the market, but imports from Trinidad and Tobago and Mexico fill seasonal gaps. Buyers should verify that suppliers have ISO 9001 certification for quality management and that their product meets US fertilizer regulations, including heavy metal limits for cadmium, lead, and arsenic set by the Association of American Plant Food Control Officials (AAPFCO) [5].

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

US ag distributors and co-ops are the primary buyers of imported urea and ammonium nitrate, purchasing in bulk—typically 20,000 to 50,000 metric ton shipments—for storage at regional terminals. Distributors like CHS Inc., GROWMARK, and Land O’Lakes procure through long-term contracts with producers, often on a cost-and-freight (CFR) basis to US Gulf ports such as New Orleans, Houston, or Mobile. Co-ops, which aggregate demand from member farmers, may purchase smaller volumes (5,000 to 15,000 metric tons) through spot tenders or membership in purchasing groups. The key specifications that matter to these buyers are nitrogen content (guaranteed minimum), particle size distribution (to avoid segregation during blending), and moisture content (to prevent caking). For ammonium nitrate, the product must also be classified as a non-hazardous fertilizer under DOT regulations, which requires that it pass the thermal stability test (UN 1942) and be packaged in approved bags or bulk containers [6].

Procurement cycles are seasonal, with the largest demand for urea and ammonium nitrate occurring in the spring (March–May) for corn and wheat planting, and in the fall (September–November) for winter wheat and cover crops. US buyers typically contract for spring delivery in the preceding September–October, leveraging forward pricing to lock in margins. For spot purchases, buyers monitor the US Gulf Coast urea price index published by Green Markets (a Bloomberg company), which tracks daily spot prices for granular urea and UAN solutions. This index, along with the Ammonia Price Index from the International Fertilizer Association (IFA), provides benchmarks for contract negotiations [7].

Certifications and Import Requirements

Importing urea and ammonium nitrate into the US requires compliance with several federal and state regulations. The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) regulates the import of fertilizers to prevent the introduction of plant pests; urea and ammonium nitrate are generally exempt from APHIS permits as they are synthetic, non-organic products, but importers must file a Notice of Arrival for any shipments containing animal-derived components (which is rare for these products) [8]. The EPA requires that all fertilizer products sold in the US be registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) if they contain any pesticidal claims; standard agricultural urea and ammonium nitrate without such claims are exempt from FIFRA registration but must meet state-level registration requirements in all 50 states. The Association of American Plant Food Control Officials (AAPFCO) provides model regulations for state fertilizer laws, including labeling requirements for guaranteed analysis, net weight, and manufacturer information.

For ammonium nitrate, the US Department of Homeland Security (DHS) regulates its sale and storage under the Chemical Facility Anti-Terrorism Standards (CFATS) program, which applies to facilities that handle certain quantities of ammonium nitrate. Importers must ensure that their downstream customers have appropriate security plans in place. Additionally, the US Coast Guard and DOT regulate the maritime transport of ammonium nitrate as a Class 5.1 oxidizing solid, requiring that vessels have proper ventilation and fire suppression systems. Urea is classified as a non-hazardous material under DOT regulations (UN 3077, Environmentally Hazardous Substance), but shipments must still be labeled and documented accordingly [6].

Pricing and Lead Time Context

Urea and ammonium nitrate prices are highly volatile, driven by natural gas costs, global supply-demand balances, and seasonal demand. As of early 2025, US Gulf Coast granular urea prices have ranged from $350 to $550 per metric ton FOB, while ammonium nitrate prices have been slightly higher, between $400 and $600 per metric ton FOB, due to higher production costs and limited supply [7]. Latin American suppliers, with lower natural gas costs in Trinidad and Tobago (where gas is priced at $3–$5 per MMBtu versus $2–$4 in the US), can offer competitive FOB prices, but freight costs from Latin America to the US Gulf add $20–$40 per metric ton for a 5,000–10,000 metric ton shipment. Lead times from Latin American producers are typically 2–4 weeks for bulk shipments, compared to 4–8 weeks from Africa, making LATAM the preferred source for US buyers during peak seasons.

Buyers should also consider the cost of storage and handling at US terminals, which can add $15–$25 per metric ton for warehousing and rehandling. For co-ops that lack their own storage, partnering with a distributor that has terminal capacity is essential. Contract terms often include price adjustment clauses based on the US Gulf Coast urea index, with a premium of $10–$20 per metric ton for guaranteed supply during peak periods. Spot purchases during spring may command a $30–$50 premium over contract prices, reflecting market tightness [7].
