LOI in Crude Oil Trading: The Complete Guide to Letters of Intent for International Oil Transactions

LOI in Crude Oil Trading: The Complete Guide to Letters of Intent for International Oil Transactions

One of the first documents exchanged during many international crude oil negotiations is the Letter of Intent, commonly known as the LOI.

If you’ve spent time around oil brokers, mandates or commodity traders, you’ve probably heard someone say:

“The buyer should issue an LOI.”

Many newcomers assume an LOI is the final contract.

It isn’t.

Instead, a Letter of Intent is a formal communication expressing a buyer’s serious interest in pursuing a commercial transaction under specified conditions. It often serves as an early step that helps both parties determine whether further negotiations are worthwhile before moving into more detailed commercial documentation.

If you’re new to refinery procurement, our guide on How Refineries Buy Crude Oil  explains how professional buyers evaluate opportunities before exchanging transaction documents.

What Is a Letter of Intent (LOI)?

An LOI is a written document expressing a company’s intention to pursue a commercial transaction.

Think of it as saying:

“We are seriously interested in discussing this purchase under these conditions.”

An LOI helps establish commercial direction before more detailed transaction documents are exchanged.

Unlike casual emails or WhatsApp messages, a professionally prepared LOI presents structured commercial information.

Why Buyers Issue an LOI

Professional buyers issue LOIs for several practical reasons.

They may want to:

• identify the required crude grade

• communicate desired quantities

• outline preliminary commercial expectations

• begin structured negotiations

• demonstrate serious business interest

For example, a refinery looking for Bonny Light Crude Oil  or Forcados Crude Oil  may begin with an LOI before requesting more detailed commercial documentation.

When Does an LOI Appear in the Transaction Process?

Although every transaction is different, a simplified commercial sequence often looks like this:

1. Initial contact

2. Market discussion

3. Buyer interest

4. LOI

5. Commercial clarification

6. ICPO (Irrevocable Corporate Purchase Order) 

7. Seller response

8. Contract negotiation

9. Operational preparation

10. Crude Oil Lifting 

The important lesson is this:

The LOI helps open structured commercial discussions—it does not automatically create a completed oil deal.

What Should a Professional LOI Contain?

A well-prepared LOI usually includes clear commercial information.

Typical sections include:

Buyer Information

• company name

• registered address

• authorized representative

• corporate details

Product Information

• crude grade

• required quantity

• preferred delivery period

Commercial Expectations

• pricing basis

• delivery preference

• destination

• payment expectations

Corporate Authorization

• signature

• date

• company identification

Professional LOIs are clear, specific and commercially organized.

Example LOI Structure

Here’s a simplified example.

This demonstrates structure—not a universal template.

LOI vs ICPO

One of the most common beginner mistakes is confusing LOIs with ICPOs .

Here’s the difference.

Both documents matter—but they serve different purposes.

LOI vs Sales Contract

An LOI is also different from a Sales and Purchase Agreement (SPA).

We’ll cover SPAs in detail later in this content series.

Why Sellers Still Perform Due Diligence

Receiving an LOI does not eliminate verification.

Professional sellers may review:

• company identity

• corporate registration

• authorized signatory

• transaction consistency

• commercial credibility

This follows the same disciplined approach discussed in How International Buyers Source Nigerian Crude .

Verification protects legitimate businesses on both sides.

How LOIs Connect to Nigerian Crude Transactions

Whether the buyer is interested in:

• Bonny Light 

• Forcados 

• Qua Iboe 

• Bonga 

• Egina 

the LOI remains only one step within a much larger commercial process.

Later operational stages still involve:

• terminal scheduling

• vessel nomination

• regulatory compliance

• cargo lifting

Nigeria’s upstream petroleum operations are regulated by the Nigerian Upstream Petroleum Regulatory Commission (NUPRC) , while the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA)  regulates midstream and downstream activities.

Common LOI Mistakes

Avoid these common mistakes.

Vague Commercial Terms

Professional buyers communicate specific requirements.

Missing Company Information

Corporate identity should be clear.

Unrealistic Quantities

Extraordinary claims deserve careful verification.

No Authorized Signatory

Professional documents require proper authorization.

Assuming an LOI Guarantees a Deal

An LOI begins discussions—it does not replace due diligence.

How LOIs Fit Into the Oil Trading Document Chain

As Paradise MultiTrade’s knowledge hub grows, you’ll see how these documents connect.

Typical commercial progression:

1. Inquiry

2. LOI

3. ICPO 

4. FCO

5. SPA

6. Operational Documents

7. Lifting 

Each document serves a different commercial purpose.

Understanding the sequence builds credibility during real negotiations.
