Energy commodity procurement operates in one of the most technically complex, commercially volatile, and compliance-intensive environments in global trade.
Refineries, industrial operators, aviation buyers, and energy distributors sourcing crude oil, diesel, or jet fuel are not buying off a shelf. They are navigating specifications defined in parts per million, pricing benchmarks that move by the minute, regulatory frameworks that vary by origin country, and logistics infrastructure that requires weeks of lead time.
This guide is built for procurement directors and supply chain executives who operate in — or are entering — the energy commodity market. It covers product specifications, supplier qualification, pricing structures, and logistics for crude oil, diesel EN590, and jet fuel Jet A-1. For the procurement fundamentals, refer to our commodity sourcing guide.
The Energy Commodity Landscape
XRT Group's energy procurement division sources and facilitates the following products:
| Product | Key Specification Standard | Primary Use |
|---|---|---|
| Crude Oil (Light Sweet) | API 35-45°, Sulfur <0.5% | Refinery feedstock |
| Crude Oil (Heavy Sour) | API 20-30°, Sulfur 1-3% | Complex refinery feedstock |
| Diesel D2 / EN590 | Sulfur <10ppm, Cetane min 51 | Road transport, industrial power |
| Jet Fuel Jet A-1 | ASTM D1655, Flash point min 38°C | Commercial aviation |
| JP54 (Jet A) | MIL-DTL-5624 | Military aviation, some civil |
| Fuel Oil IFO 180/380 | ISO 8217 | Marine bunker, heavy industry |
Crude Oil Procurement: Technical Specifications
Crude oil is classified by density (API gravity) and sulfur content, which determine its refining economics and which refineries can process it.
API Gravity
API gravity measures crude oil density relative to water:
- Light crude: API > 31.1° (e.g., WTI at ~39°, Brent at ~38°)
- Medium crude: API 22.3° to 31.1°
- Heavy crude: API < 22.3° (e.g., Venezuelan Boscan at ~10°)
Light crude commands a premium because it yields higher proportions of valuable refined products (gasoline, diesel, jet fuel) with lower processing costs.
Sulfur Content
- Sweet crude: Sulfur < 0.5% (easier to refine, lower emissions in products)
- Sour crude: Sulfur > 0.5% (requires desulfurization, higher processing cost)
Crude Oil Pricing Benchmarks
Crude oil is priced against international benchmarks with differentials (plus or minus) based on quality and location:
- Brent Crude (ICE): Global benchmark for Atlantic basin crude
- WTI (NYMEX): US benchmark, Cushing Oklahoma delivery
- Dubai/Oman: Middle East benchmark for Asia-Pacific trade flows
- ESPO: Russian Pacific grade, significant Asian market reference
A procurement contract for crude oil will specify pricing as: "[Benchmark] ± [differential] per barrel at [measurement date]"
Diesel EN590: The Industrial Standard
EN590 is the European standard for road transport diesel, now the de facto specification for industrial diesel procurement globally.
EN590 Key Specifications
| Parameter | Specification |
|---|---|
| Sulfur content | Max 10 mg/kg (10 ppm) |
| Cetane number | Min 51.0 |
| Density at 15°C | 820–845 kg/m³ |
| Flash point | Min 55°C |
| Viscosity at 40°C | 2.00–4.50 mm²/s |
| Polycyclic aromatic hydrocarbons | Max 8.0% m/m |
| Total contamination | Max 24 mg/kg |
D2 vs. EN590: What's the Difference?
"D2" is a general designation for Gas Oil / Diesel used in less standardized market contexts. EN590 is the stricter European specification standard. Most reputable industrial buyers and their refineries require EN590 certification with independent inspection.
Red flag: Any supplier offering "D2 Diesel" without providing EN590 certification and independent SGS or Bureau Veritas testing reports should be approached with significant caution.
Jet Fuel Procurement: Jet A-1 and JP54
Aviation fuel procurement operates under the strictest quality and chain-of-custody requirements of any energy commodity. A contaminated fuel load entering an aircraft fuel system is a catastrophic safety event.
Jet A-1 Specifications
| Parameter | Specification |
|---|---|
| Flash point | Min 38°C |
| Freezing point | Max -47°C |
| Density at 15°C | 775–840 kg/m³ |
| Net heat of combustion | Min 42.8 MJ/kg |
| Aromatic content | Max 25% v/v |
| Sulfur total | Max 0.30% m/m |
JP54 vs Jet A-1
JP54 is a military-specification fuel primarily used by US military aviation. Some civilian operators in certain markets reference JP54, but for international commercial aviation, Jet A-1 under DEF STAN 91-091 is the standard.
Critical note: The market for "JP54" is heavily populated by fraudulent offers. Legitimate JP54 procurement occurs through direct defense contracting frameworks, not through unsolicited broker offers.
Supplier Qualification for Energy Commodities
The energy commodity market has a well-documented problem with non-performing intermediaries.
What Legitimate Suppliers Provide
- ✅ Proof of Product (POP) — SGS or Bureau Veritas inspection report from a recent transaction
- ✅ Product specification sheet matching the requested grade
- ✅ Export license or allocation documentation from the refinery or terminal
- ✅ Financial references or banking coordinates (not for payment — for due diligence)
- ✅ Signed seller's mandate or authorization chain documentation
- ✅ Willingness to execute a proper commercial contract before any financial transaction
What Illegitimate Suppliers Do
- ❌ Request "engagement fees," "processing fees," or "compliance deposits" before contract execution
- ❌ Cannot produce SGS/BV inspection reports from recent verified transactions
- ❌ Present LOI/ICPO procedures that require the buyer to pay before receiving any documentation
- ❌ Offer prices significantly below current Platts or benchmark assessments
- ❌ Cannot verify their access to the refinery or terminal they claim to supply from
Pricing Mechanisms for Energy Commodity Contracts
Spot Purchases
Single cargo transactions priced at current market rates. Appropriate for short-term supply gaps, market opportunism, and testing new supplier relationships at lower volume.
Term Agreements
Multi-delivery contracts (monthly, quarterly, annual) at fixed price, floating price, or price band/collar structures. Term agreements provide supply security in tight markets and reduce procurement overhead.
Frequently Asked Questions
What is the minimum order for diesel EN590 procurement?
Bulk diesel procurement typically starts at 1,000 MT per cargo (approximately 1.18 million liters). Smaller volumes may be accommodated via ISO tank or truck-delivered product depending on location.
What documentation is required for a crude oil purchase?
Standard documentation includes: SGS inspection certificate (quantity and quality), Bill of Lading, COO (Certificate of Origin), commercial invoice, packing list, and for some jurisdictions, a phytosanitary or fumigation certificate equivalent for cargo.
How does XRT Group handle price volatility for energy commodities?
We structure contracts with pricing mechanisms appropriate to the buyer's risk profile — fixed price for budget-certainty buyers, floating indexed pricing for buyers who want to capture market downturns, and collar structures for those managing both upside and downside risk.
Does XRT Group handle US domestic fuel distribution?
Yes. Our logistics infrastructure includes North American truck and rail distribution for diesel and refined products, with particular capability in Alaska and Hawaii — markets that require specialized logistics coordination due to their geographic position.
