Buying crude oil directly requires more than finding a company that advertises a “direct refinery supply.” In physical crude trading, the refinery, producer, national oil company, integrated energy company and trading company can have different roles in the transaction.

Refinery crude supply therefore needs to be understood from the perspective of who actually controls the crude, who is authorized to sell it, where the cargo is located, and whether the crude matches the buyer’s refinery requirements.

For a serious buyer, the objective is not simply to eliminate every intermediary. The objective is to establish a legitimate supply chain, verify the seller’s authority and obtain commercially workable crude under a clearly defined contract.

Can You Buy Crude Oil Through Refinery Crude Supply?

A refinery is normally a buyer and processor of crude oil rather than the original producer of the crude.

The U.S. Energy Information Administration describes refineries as facilities that process crude oil into petroleum products. That means a refinery’s relationship with crude is primarily based on securing suitable feedstock for its processing system.

There are exceptions to the simple producer-to-refinery model. An integrated oil company may operate upstream production, crude marketing and refining businesses. A refinery may also have affiliated trading operations or procurement arrangements with producers.

For that reason, a buyer asking for direct refinery supply should establish exactly what “direct” means in the proposed transaction.

The seller could be:

• An upstream crude producer
• A national oil company or its authorized marketing entity
• An integrated oil company
• A refinery-affiliated trading company
• An independent crude trader
• Another entity with demonstrable contractual authority over the cargo

The important issue is control and authority over the crude, not the marketing label attached to the offer.

What Refinery Crude Supply Actually Means

The term can describe several different procurement structures.

A producer-direct transaction involves an upstream producer selling crude to a refinery or another qualified buyer.

With an integrated-company transaction, crude may move between affiliated upstream, trading and refining businesses.

Commodity traders can also purchase or control crude and subsequently resell it to a refinery or another buyer.

A refinery-linked arrangement can therefore provide access to crude without necessarily meaning that the refinery itself owns every barrel being offered.

This distinction matters because a buyer should know which entity will appear as the contractual seller, which entity has title or control of the cargo, and which entity is responsible for delivery.

Identify the Real Seller Behind Refinery Crude Supply

Before discussing a large cargo, establish the identity and authority of the seller.

A buyer should request enough information to answer several basic questions:

1. Who is the legal seller?
2. Who owns or controls the crude?
3. What gives the seller authority to sell it?
4. What crude grade is being offered?
5. Where will the crude be loaded?
6. What is the proposed loading window?
7. What entity will execute the sale and purchase agreement?
8. Who is responsible for transportation and delivery?

A company website, corporate profile or broker introduction does not by itself establish control of a physical crude cargo.

The commercial chain should be understandable from the beginning.

Match the Crude to a Refinery Crude Supply Requirement

Crude oil is not a uniform commodity.

Different crude streams have different characteristics, and those characteristics can affect refinery economics. API gravity and sulfur content are among the important properties used when evaluating crude feedstock.

Current EIA data illustrate this variation. U.S. refinery crude inputs averaged 33.32 degrees API gravity and 1.35% sulfur in June 2026. Regional refinery slates differed considerably; the U.S. Gulf Coast averaged 33.85 degrees API and 1.39% sulfur in the same month, while the U.S. West Coast averaged 28.90 degrees API and 1.01% sulfur.

These figures are not specifications for every refinery. They demonstrate why buyers should not treat one crude grade as automatically suitable for every processing system.

A refinery buyer should evaluate:

• API gravity
• Sulfur content
• Crude assay
• Acidity where relevant
• Metals and other contaminants
• Viscosity
• Expected product yields
• Refinery configuration
• Transportation economics

A low-priced barrel can become an unattractive purchase if the refinery cannot process it efficiently or if transportation costs eliminate the apparent price advantage.

Prepare the Buyer’s Crude Requirement

Before approaching a supply desk, the buyer should prepare a clear crude requirement.

At minimum, the requirement should identify:

Crude grade: The preferred grade or acceptable quality range.

Quantity: Required cargo size or monthly/annual volume.

Delivery basis: FOB, CIF, CFR or another agreed commercial basis.

Loading location: The preferred export terminal or acceptable loading region.

Destination: The refinery, port or discharge location.

Delivery window: The period in which the cargo must be available.

Contract duration: Spot cargo, term contract or recurring supply.

Inspection: Independent inspection requirements and the point at which quantity and quality will be determined.

Payment structure: The commercial payment mechanism acceptable to the buyer and seller.

A precise requirement allows a legitimate supplier to determine whether its available crude actually matches the buyer’s needs.

Verify Refinery Crude Supply Before Contracting

Supplier verification should happen before the transaction becomes financially significant.

The buyer should examine the legal identity of the proposed seller and establish its role in the physical supply chain.

Useful verification questions include:

• Is the company registered and operating?
• Does it have a demonstrable relationship with the producer or crude owner?
• Is it authorized to market the particular crude grade?
• Does the proposed loading point correspond with the cargo?
• Can the seller explain the contractual supply chain?
• Are the proposed quantity and loading window commercially plausible?
• Can independent inspection be arranged?
• Are required export, customs or regulatory permissions available?

The purpose is not to collect paperwork for its own sake. The purpose is to establish that the proposed seller can actually perform the transaction being offered.

Buyers should also distinguish between proof that a company exists and proof that the company controls the specific crude being offered.

Those are different questions.

Review the Commercial Structure Behind Refinery Crude Supply

Crude oil is commonly priced against recognized benchmarks with a premium or discount reflecting the particular crude, market and transaction.

Depending on the crude and market, the pricing mechanism may reference benchmarks such as Brent, West Texas Intermediate or Dubai/Oman.

The buyer should understand:

• Benchmark
• Differential
• Pricing period
• Quality adjustments
• Freight
• Insurance
• Terminal costs
• Inspection costs
• Financing costs
• Applicable taxes or duties
• Other transaction-specific charges

The quoted crude price is therefore only one component of the acquisition economics.

A cargo that appears cheaper at the loading point can become more expensive after freight, handling and other costs are included.

Direct Refinery Supply vs Producer-Direct Crude

“Direct” can mean different things in physical oil trading.

Supply structure	Primary relationship	What the buyer should establish
Producer-direct	Producer → Buyer/Refinery	Producer authority, crude availability and loading terms
Integrated company	Upstream/Trading → Refinery/Buyer	Corporate relationship and contractual seller
Refinery-linked	Refinery/trading relationship → Buyer	Actual crude controller and authority
Trader	Trader → Buyer	Title, supply agreement and performance capability
Broker introduction	Broker → Buyer/Seller	Broker’s role and identity of the actual seller

A broker or intermediary is not automatically a problem. In international commodities, intermediaries can perform legitimate commercial functions.

The risk arises when the buyer cannot determine who actually controls the cargo.

How Current Market Conditions Affect Crude Procurement

Crude procurement decisions also need to account for changing global supply conditions.

The IEA’s August 2026 Oil Market Report projected global oil supply at about 102 million barrels per day for 2026, while refinery crude throughputs were expected to average about 80.9 million barrels per day in July and decline by 2.5 million barrels per day on average for the year. The report also described substantial disruption to international oil flows and significant crude-price volatility.

This matters to procurement because a buyer cannot assume that a quoted crude grade, loading location or delivery window will remain equally available throughout the year.

Supply disruption can affect:

• Loading schedules
• Freight availability
• Regional crude differentials
• Refinery feedstock choices
• Inventory decisions
• Alternative sourcing requirements

For a refinery buyer, procurement should therefore combine commercial pricing with supply reliability and logistical feasibility.

Common Mistakes When Buying Crude Directly

Assuming “direct” means legitimate

A direct-supply claim does not prove that the seller controls the crude.

Buying solely on headline price

The cheapest quoted barrel is not necessarily the cheapest usable barrel.

Ignoring crude quality

API gravity, sulfur and other characteristics can materially affect processing economics.

Failing to identify the contractual seller

The buyer should know exactly which legal entity will sign the contract and carry the relevant obligations.

Ignoring the loading point

A credible crude transaction needs a commercially credible loading location and delivery structure.

Treating documentation as proof of performance

Documents should support verification, but buyers should evaluate whether the entire commercial chain makes sense.

Failing to consider logistics

Freight, vessel availability, terminal capacity and destination requirements can materially affect the transaction.

How to Approach a Refinery Crude Supply Desk

A serious buyer should approach a supplier with a commercial requirement rather than an open-ended request for “cheap crude.”

The request should identify the desired crude grade, volume, destination, delivery window and preferred commercial basis.

The supplier can then determine whether it can provide:

• A specific spot cargo
• A term supply arrangement
• Producer-direct crude
• Refinery-linked crude
• Trader-sourced crude
• An alternative crude grade that fits the buyer’s refinery

This approach also makes it easier to compare competing offers because the commercial requirements remain consistent.

Request Refinery Crude Supply

For buyers seeking physical crude, the next step is to define the requirement clearly and establish the supply route before moving toward a commercial contract.

Global Petroleum Advisors provides a dedicated Crude Oil Supply & Trading service for buyers seeking structured access to crude supply and trading opportunities.

The objective should be straightforward: identify a suitable crude source, establish the seller’s authority, confirm the cargo and commercial terms, and coordinate the transaction through the appropriate supply and logistics chain.

Frequently Asked Questions

Can I buy crude oil directly from a refinery?

Sometimes, but the terminology needs to be clarified. Refineries are generally crude buyers and processors. A supposed “direct refinery” transaction may actually involve an integrated oil company, affiliated trading arm, producer or authorized crude supplier.

What does refinery crude supply mean?

It refers to a crude procurement relationship connected to a refinery or refinery procurement requirement. The actual contractual seller may be a producer, national oil company, integrated energy company or authorized trader.

Who normally sells crude oil?

Crude can be sold by upstream producers, national oil companies, integrated energy companies, authorized marketing entities and commodity trading companies.

What should a crude buyer verify?

The buyer should verify the seller’s corporate identity, authority over the crude, crude grade, quantity, loading location, delivery window, contractual structure and applicable inspection and regulatory requirements.

Does crude quality matter when buying directly?

Yes. API gravity, sulfur and other crude characteristics affect refinery processing and economics. The buyer should compare the offered crude with the refinery’s feedstock requirements.

Is buying directly always cheaper?

No. Removing an intermediary does not automatically produce a lower delivered cost. Freight, quality differentials, financing, terminal charges, inspection and other costs can materially affect the economics.

What information should a buyer provide when requesting crude?

A professional crude requirement should normally include the desired grade or specification, quantity, delivery location, loading or delivery window, commercial basis, contract duration and inspection requirements.

Should buyers avoid brokers?

Not necessarily. A legitimate broker can introduce buyers and sellers or assist with a transaction. The important question is whether the buyer can identify and verify the actual entity controlling and selling the crude.

Conclusion

Buying crude oil “directly from a refinery” requires a more precise understanding of the physical oil supply chain.

The refinery may be the end buyer of crude rather than its original seller. The actual supply can originate with a producer, national oil company, integrated energy company, affiliated trading operation or authorized crude marketer.

For that reason, the strongest procurement approach is not simply to search for a company claiming to offer direct refinery supply. Buyers should identify the actual crude controller, match the crude to the refinery’s requirements, verify the seller’s authority, understand the full delivered economics and establish clear contractual responsibilities.

That is what turns a claimed direct crude opportunity into a properly evaluated procurement opportunity.
