Exporting Fuel Oil and Diesel to the US — Energy Traders and Distributors

Fuel oil and diesel are the backbone of the US energy infrastructure, powering industrial boilers, marine engines, and the nation’s transportation fleet. For US energy traders and distributors, securing reliable, cost-competitive supplies of these refined petroleum products is a constant strategic priority. Latin America, with its abundant crude reserves and growing refining capacity, has emerged as a critical source region, offering shorter shipping routes and favorable trade terms compared to traditional suppliers in the Middle East and Europe. This page provides a comprehensive guide for US buyers and Latin American suppliers navigating the fuel oil and diesel trade corridor, covering specifications, supplier landscapes, procurement practices, certifications, pricing, and how Coppermont facilitates high-volume transactions.

Product Specifications and Grades Relevant to US Buyers

Fuel oil and diesel are not homogeneous commodities; they are graded according to viscosity, sulfur content, and intended end use. For US buyers, the most relevant fuel oil grades are No. 6 (residual fuel oil, or Bunker C) and No. 2 (distillate fuel oil, which overlaps with diesel). No. 6 fuel oil, typically used in industrial boilers, power plants, and large marine vessels, is defined by ASTM D396 and is often specified by viscosity (e.g., 180 cSt or 380 cSt at 50°C) and sulfur content. Under IMO 2020 regulations, sulfur content for marine fuel cannot exceed 0.5% by weight in most emission control areas, though high-sulfur fuel oil (HSFO, above 3.5% sulfur) is still traded for vessels equipped with scrubbers. Diesel, or No. 2 fuel oil, is governed by ASTM D975 and is further divided into ultra-low sulfur diesel (ULSD, ≤15 ppm sulfur) for on-road use and low-sulfur diesel (≤500 ppm) for off-road and industrial applications. US buyers typically require fuel oil with a flash point above 60°C, a pour point suitable for handling in temperate climates, and sediment and water content below 0.5%. Latin American refineries, such as those in Venezuela, Brazil, and Colombia, produce a range of fuel oils that meet these specifications, though sulfur content and viscosity can vary significantly by crude source and refining process. For diesel, the key parameter is cetane number (minimum 40 for on-road in the US), along with distillation curve and stability. Suppliers must provide certificates of analysis (COA) from accredited laboratories to verify compliance with ASTM standards before shipment. Buyers should also be aware of blending flexibility: many US distributors blend fuel oils on arrival to adjust viscosity and sulfur content, so consistent base feedstock from Latin America is highly valued.

Latin American and African Supplier Landscape

Latin America is a major exporter of fuel oil and diesel, driven by the region’s substantial crude oil production and refining capacity. According to the US Energy Information Administration, in 2023, Latin America supplied approximately 15% of total US petroleum product imports, with fuel oil and diesel accounting for a significant share [1]. The primary suppliers are Mexico (Pemex refineries), Venezuela (PDVSA, despite sanctions, still exports through intermediaries), Brazil (Petrobras), and Colombia (Ecopetrol). Mexico’s refineries, such as the Salina Cruz and Tula complexes, produce high-sulfur fuel oil that is often blended or further processed in the US Gulf Coast. Brazilian refineries, particularly the Replan and Reduc complexes, produce ULSD that meets US specifications, and Petrobras has invested in desulfurization units to increase output of low-sulfur diesel. Colombia’s Ecopetrol exports fuel oil from its Barrancabermeja and Cartagena refineries, with a growing share of IMO-compliant bunker fuel. Other Latin American players include Argentina (through YPF and its refineries) and Chile (ENAP, though volumes are smaller). In Africa, Nigeria (NNPC) and Angola (Sonangol) export fuel oil, but volumes to the US have declined due to competition from European and Middle Eastern suppliers and local refining challenges. However, African heavy-sour crude oil is often processed in Latin American refineries, making the supply chain intertwined. For US traders, the key advantage of Latin American supply is reduced freight costs and transit times: a voyage from Brazilian ports to Houston takes approximately 10–12 days, compared to 25–30 days from the Middle East. This agility allows traders to respond quickly to price arbitrage and seasonal demand spikes, such as increased heating oil consumption in winter or diesel demand during harvest seasons. The supplier landscape is characterized by state-owned enterprises and large national oil companies (NOCs), which often require long-term contracts or spot cargoes via tenders. Smaller independent refineries in the region, such as those in Ecuador and Peru, also offer spot volumes, but quality consistency can be a concern. US buyers typically evaluate suppliers based on track record, creditworthiness, and ability to provide COAs from ISO 17025-accredited labs. The market is also influenced by US sanctions on Venezuela and Iran, which affect supply flows and require careful due diligence on cargo origin [2].

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

The US market for fuel oil and diesel is diverse, with buyers ranging from large integrated oil companies to independent distributors and end-users. The primary buyer types are energy traders (who buy and sell cargoes on the spot market, often through brokers or exchanges like the NYMEX), wholesale distributors (who supply retail stations, industrial accounts, and commercial fleets), and large industrial consumers (such as power plants, refineries, and marine bunkering companies). Energy traders focus on arbitrage opportunities, buying cargoes when prices are low and selling when demand peaks, and they prioritize liquidity, contract flexibility, and credit terms. Wholesale distributors, by contrast, require consistent quality and reliable delivery schedules to meet downstream commitments, and they often enter into term contracts (30–90 days) with suppliers. Industrial consumers, such as power plants burning No. 6 fuel oil, are less price-sensitive but demand strict adherence to specifications, as off-spec fuel can damage burners or violate emissions permits. Procurement mechanisms include spot cargo inquiries (typically 50,000–500,000 barrels per cargo), term contracts (monthly or quarterly volumes), and online trading platforms (e.g., Platts Market on Close). For fuel oil, the most common incoterm is CIF (Cost, Insurance, Freight) delivered to US Gulf Coast ports (Houston, New Orleans, Beaumont) or East Coast ports (New York, Philadelphia). For diesel, FOB (Free on Board) from Latin American ports is also common, with the buyer arranging shipping. Specs that matter most are sulfur content (for regulatory compliance), viscosity (for handling and combustion), and flash point (for safety). US buyers increasingly require IMO 2020-compliant fuel oil (≤0.5% sulfur) for marine bunkering, while on-road diesel must meet EPA’s ULSD standard of 15 ppm sulfur. Additionally, buyers often request sampling and testing by third-party inspectors (such as SGS or Intertek) at both loading and discharge ports to ensure quality and quantity. The payment terms for these transactions typically involve letters of credit (L/C) from major banks, with cash against documents (CAD) for trusted counterparties. US buyers also monitor US refinery utilization rates and inventory levels reported by the EIA weekly, as these influence spot pricing and demand [3].

Certifications and Import Requirements

Importing fuel oil and diesel into the US requires compliance with federal and state regulations, primarily enforced by the Environmental Protection Agency (EPA), US Customs and Border Protection (CBP), and the Department of Energy (DOE). For diesel, the key requirement is sulfur content: ULSD must not exceed 15 ppm, and all diesel sold for on-road use must be registered with the EPA under the Motor Vehicle Diesel Fuel program. Importers must submit a notification to the EPA at least 30 days before the first import of a new fuel type, and each shipment must be accompanied by a certificate of analysis showing compliance with ASTM D975. For fuel oil, the primary regulations concern sulfur content under the IMO 2020 rules for marine fuel, and for industrial use, emissions limits under the Clean Air Act. Additionally, all petroleum imports require a CBP entry filing with the appropriate Harmonized Tariff Schedule (HTS) codes: 2710.19.20 for fuel oils (other than crude) and 2710.19.40 for diesel. Importers must pay a duty of 10.5 cents per barrel for fuel oil and 10.5 cents per barrel for diesel, though free trade agreements (such as the USMCA for Mexican-origin products) may reduce or eliminate duties. Suppliers must provide a certificate of origin (e.g., Form A for GSP-eligible countries or a NAFTA/USMCA certificate) to claim preferential tariff treatment. Other certifications include ISO 9001 for quality management and ISO 14001 for environmental management, which are increasingly demanded by US buyers as part of supplier qualification. For bunker fuel, the International Maritime Organization (IMO) requires a Bunker Delivery Note (BDN) and a fuel oil sample for each supply. US buyers also require evidence of compliance with the EPA’s Renewable Fuel Standard (RFS) if the diesel is blended with biodiesel. Failure to meet these requirements can result in cargo rejection, fines, or loss of import privileges. Latin American suppliers must work with experienced customs brokers and legal advisors to navigate the complex regulatory landscape, especially given the evolving sanctions on Venezuelan crude and the potential for future tariffs [4].

Pricing and Lead Time Context

Pricing for fuel oil and diesel in the US market is highly volatile and tied to global benchmarks. Fuel oil is typically priced relative to the Platts US Gulf Coast 3% sulfur fuel oil assessment or the NYMEX Brent crude oil futures, with discounts or premiums based on sulfur content, viscosity, and delivery location. In 2023, the average price for No. 6 fuel oil (3% sulfur) delivered to the US Gulf Coast ranged from $60 to $90 per barrel, while ULSD (diesel) averaged $90 to $120 per barrel, reflecting refining margins and seasonal demand [5]. Latin American suppliers often offer discounts of $1–$5 per barrel compared to Middle Eastern or European cargoes due to lower freight costs and favorable trade relationships. However, pricing can vary widely based on the specific grade: low-sulfur fuel oil (≤0.5% sulfur) commands a premium of $10–$20 per barrel over high-sulfur fuel oil. Lead times for spot cargoes from Latin America are typically 2–4 weeks from contract signing to delivery, including 10–12 days for shipping from Brazil or Colombia to the US Gulf Coast. Term contracts may have lead times of 30–45 days, allowing for production scheduling and blending. US buyers should factor in the cost of third-party inspection ($5,000–$15,000 per cargo), insurance (0.1–0.3% of cargo value), and potential demurrage charges if vessels are delayed at port. The payment mechanism—L/C or CAD—also affects effective pricing, as bank charges and credit risk are embedded in the transaction. For traders, the key to profitability is timing the market: buying during periods of contango (when future prices are higher than spot) and selling during backwardation. Seasonal factors, such as increased heating oil demand in winter and diesel demand for agricultural harvests in fall, create predictable price spikes. US buyers should also monitor the EIA’s weekly petroleum status report for inventory levels and refinery utilization, which directly impact spot pricing [6].
