Caribbean Fuel Supply Chain:
Diesel, Jet Fuel & LPG Procurement Guide

Caribbean Energy Dependence: A Region Built on Imported Fuel

The Caribbean is among the most energy-import-dependent regions on the planet. With the exception of Trinidad and Tobago — which benefits from domestic natural gas production — virtually every island nation imports more than 90% of the petroleum products it consumes. From Barbados to Haiti, from Jamaica to the Bahamas, the lights stay on, the planes fly, and the cooking fires burn because of a continuous flow of refined fuel products arriving by tanker from overseas refineries.

This structural dependence makes reliable, competitively priced ULSD, gasoline, and jet fuel procurement a mission-critical function for Caribbean governments, state utilities, private distributors, and airport operators. A supply disruption of even a few days can cascade into rolling blackouts, grounded aircraft, and empty cooking-gas cylinders across entire island populations. For procurement teams and energy traders operating in this market, understanding the full supply chain — from US Gulf Coast refinery to Caribbean terminal — is essential to sourcing efficiently and managing risk.

Key Petroleum Products for the Caribbean Market

Caribbean buyers typically source five primary petroleum products, each serving distinct end-use sectors:

• Ultra-Low Sulfur Diesel (ULSD): The single highest-volume product in most Caribbean markets. ULSD (15 ppm sulfur maximum under ASTM D975) is the backbone fuel for diesel power generation — which accounts for 60–80% of electricity production across most island nations — as well as road transport, agricultural equipment, and marine use. Demand is relatively inelastic because most island power grids have no viable alternative to diesel generation in the short term.
• Jet A-1 Aviation Turbine Fuel: Essential for all commercial and cargo aviation across the Caribbean. Jet A-1 meets DEF STAN 91-091 and ASTM D1655 specifications and is the standard international aviation grade. Caribbean airports from Kingston to Nassau to Bridgetown require a continuous, uninterrupted supply to support both regional carriers and international routes. Fuel quality and chain of custody documentation are non-negotiable in aviation procurement.
• LPG / Propane: Liquefied petroleum gas is the dominant household cooking fuel across the English-speaking Caribbean, French Antilles, and much of Haiti and the Dominican Republic. LPG is also used industrially for manufacturing processes, hospitality operations, and backup power. Propane typically moves in ISO tank containers or pressurized LPG tanker vessels to pressurized shore-side storage facilities.
• Heavy Fuel Oil (HFO 380 / HFO 180): Used primarily in large diesel power plants and, to a declining degree, in marine bunkering. HFO 380 (viscosity 380 cSt at 50°C) and HFO 180 are high-sulfur residual fuel grades. Power utilities in larger Caribbean markets such as Jamaica and the Dominican Republic have historically consumed substantial HFO volumes, though the transition to lower-sulfur alternatives is ongoing following IMO 2020 regulations.
• Gasoline (Motor Spirit): Unleaded regular and premium gasoline (87 and 93 AKI) for the road transport sector. Caribbean gasoline demand is smaller than diesel on a volume basis but serves the same continuous-replenishment procurement dynamic.

Sourcing: US Gulf Coast Refineries and Pricing Benchmarks

The US Gulf Coast (USGC) is the dominant supply origin for Caribbean fuel imports, accounting for the vast majority of petroleum products entering the region. The concentration of refinery capacity around Houston, Corpus Christi, Beaumont, and Lake Charles creates a competitive, liquid spot market with frequent vessel loadings and well-established logistics infrastructure oriented toward Caribbean and Latin American export.

Major USGC refinery clusters serving Caribbean fuel exports include:

• Houston Ship Channel area: Home to several of North America's largest refineries, with deepwater loading terminals directly accessible to ocean-going product tankers.
• Corpus Christi, Texas: A major refining and petrochemical hub with extensive distillate and gasoline export infrastructure.
• Lake Charles, Louisiana: Strategically positioned for Gulf exports, with multiple refineries producing diesel and HFO grades.

Pricing for Caribbean fuel supply is benchmarked against industry-standard price reporting services. Platts (S&P Global Commodity Insights) publishes daily assessment prices for ULSD, gasoline, Jet A-1, and HFO at Gulf Coast and New York Harbor delivery points. OPIS (Oil Price Information Service) provides rack, terminal, and spot market assessments used widely in physical trading. CIF Caribbean prices are typically calculated as the relevant Platts or OPIS benchmark plus a supply premium reflecting freight, insurance, and any regional market differential.

Shipping & Logistics: From Terminal to Island Port

Moving petroleum products from USGC loading terminals to Caribbean island destinations involves product tanker vessels ranging from small coastal traders to medium-range (MR) tankers. The vessel size selected depends on the destination port's depth restrictions, storage tank capacity at the receiving terminal, and the buyer's required delivery volume.

Key logistics parameters for Caribbean fuel shipments:

• Transit times: USGC to eastern Caribbean (Barbados, Trinidad) runs approximately 5–7 days by product tanker; to the northern Caribbean (Dominican Republic, Bahamas) typically 3–5 days; to western Caribbean (Belize, Honduras) 2–4 days.
• Minimum order quantities: Most bulk liquid petroleum cargoes are commercially viable from approximately 3,000–5,000 metric tonnes (MT) upward. Smaller parcels can move via flexi-bag or ISO tank container on general cargo vessels, but cost per unit rises significantly below full tanker loads.
• Tank farm and terminal capacity: Receiving ports must have adequate shore-side storage to accept a full parcel delivery. Many smaller island terminals operate with constrained capacity, requiring careful coordination of vessel arrival scheduling against inventory drawdown cycles. For a detailed look at port capabilities, see our Caribbean port infrastructure guide.
• Vessel classes: MR tankers (25,000–55,000 DWT) are the most common size class for Caribbean petroleum product deliveries. Smaller coastal vessels and barge-to-shore transfers serve ports with draft restrictions or limited harbor infrastructure.

Quality Specifications and ASTM Standards

Petroleum product quality for Caribbean supply is governed by internationally recognized ASTM International specifications, which define acceptable ranges for chemical composition, physical properties, and performance characteristics. Meeting these specifications is not merely a commercial best practice — it is a legal and operational requirement for fuels used in power generation, aviation, and road transport.

• ULSD Diesel: ASTM D975 Grade No. 2-D S15. Key parameters: sulfur content ≤15 ppm, cetane index ≥40, flash point ≥52°C, cloud point appropriate for tropical climates.
• Jet A-1: ASTM D1655 and DEF STAN 91-091. Critical parameters: flash point ≥38°C, freeze point ≤-47°C, thermal stability (JFTOT), density 775–840 kg/m³ at 15°C. Contamination and co-mingling risks make chain of custody documentation essential.
• LPG/Propane: GPA 2140 and ASTM D1835. HD-5 propane grade (minimum 90% propane, maximum 5% propylene) is the standard commercial grade for appliance and industrial use.
• HFO 380: ISO 8217 RMG 380. Key parameters: viscosity ≤380 cSt at 50°C, sulfur ≤3.5% (or ≤0.5% for MARPOL Annex VI compliance zones), flash point ≥60°C, water content ≤0.5% v/v.

Third-party quality inspections at load port, performed by SGS, Intertek, or Bureau Veritas, are standard practice and provide the documentary evidence needed for claims resolution if specification deviations are identified at the discharge port.

Regulatory Compliance: Export Controls, OFAC, and Import Permits

Exporting petroleum products from the United States to Caribbean destinations involves navigating a defined regulatory framework that spans US export controls and destination-country import requirements.

On the US side, petroleum product exports are subject to the following requirements:

• EAR and export licensing: Most petroleum products are EAR99 classification under the Export Administration Regulations and do not require a specific export license for non-embargoed destinations. However, exporters must complete Electronic Export Information (EEI) filing in the Automated Export System (AES).
• OFAC sanctions screening: All transactions must be screened against the Office of Foreign Assets Control (OFAC) Specially Designated Nationals (SDN) list. This applies not only to the buyer and destination country but also to vessels, brokers, financiers, and any intermediate parties involved in the transaction chain. Cuba remains subject to specific OFAC restrictions that require separate licensing for most petroleum exports.
• BIS compliance: The Bureau of Industry and Security requires exporters to maintain compliance programs and records for all export transactions.

At the destination, Caribbean buyers must typically obtain import permits or licenses from the relevant ministry of energy or national petroleum authority. Many Caribbean states also impose price controls, subsidy structures, or state purchasing monopolies on certain fuel categories — particularly LPG and diesel — that procurement teams must understand before executing supply agreements.

Storage and Terminal Operations at Receiving Ports

Effective fuel import into Caribbean island nations depends heavily on the capacity and condition of shore-side terminal infrastructure at the receiving port. Tank farms serving Caribbean fuel imports range from modern, privately operated multi-product terminals — such as those in Kingston Harbor (Jamaica), Point Lisas (Trinidad), and San Pedro de Macorís (Dominican Republic) — to smaller, state-operated facilities with more limited throughput capability.

Terminal operators and importers must coordinate on several operational parameters: available tank volume per product grade, pipeline transfer rates from vessel to shore, vapor recovery systems, safety certifications, and the timeline between vessel arrival and cargo release. For buyers with limited storage capacity, just-in-time supply planning becomes essential to avoid demurrage costs from vessels waiting at anchor for shore tanks to clear.

Blending operations — for example, mixing imported HFO with distillate cutter stock to achieve a specific viscosity grade — are performed at some larger Caribbean terminals, adding flexibility to the product slate that can be procured.
