Proof of Product (POP) in Oil Trading: What Is Real and What Is a Scam

Every oil buyer eventually asks the same question: how do I know this product exists? Sellers answer with “proof of product,” or POP. In legitimate trade, POP is a set of verifiable documents. In fraud, it is a folder of convincing PDFs that lead nowhere. This guide explains the difference.

What “Proof of Product” Actually Means

There is no single document called a POP. It is a package of records that together show a seller controls, or has a contractual right to, a specific quantity and grade of product at a specific location. Serious sellers assemble it for credible buyers, usually after a non-binding offer or LOI and often under NDA.

Be cautious of any seller who offers POP to anyone who asks, in the first message. Real inventory is commercially sensitive. Scammers use POP as bait because it costs them nothing to produce.

Documents That Can Be Legitimate

These are the records that normally appear in genuine POP packages. Each is only as good as your ability to verify it independently.

  • Tank storage agreement (TSA) or tank lease: names the terminal, the tank, the product and the tenant. Check that the tenant is the seller or its named supplier.
  • Tank storage receipt or terminal statement: confirms quantity held in a named tank at a given date. It should come from the terminal operator, not the seller.
  • Independent inspection report: a quantity and quality report from a recognized inspection company, with a report number and date.
  • Refinery or producer allocation letter: confirms the seller’s contractual right to lift volumes over a period.
  • Product specification or certificate of quality: matches the grade in the offer (API gravity, sulfur, and so on).
  • Seller’s commitment to provide a Notice of Readiness and vessel details at the right stage of the deal.

Documents That Are Commonly Fabricated

Fraudulent packages tend to share a pattern. They look heavy on stamps and light on traceable detail.

  • “Product availability” letters on the seller’s own letterhead with no third-party issuer.
  • Tank receipts that arrive as editable files or screenshots, or that name a terminal that does not exist or does not handle that product.
  • Inspection reports with no verifiable report number, or from a company that has no record of the report.
  • Product described as “available in the market” without a named tank, vessel or producer.
  • Quantities that never change across weeks of correspondence, regardless of what you ask.
  • Recycled documents where the owner, date or volume has been altered but the formatting is identical to documents seen elsewhere.

The Verification Checklist

Treat each item as pass or fail. One failure does not always mean fraud, but it means the deal pauses until it is resolved.

  1. Identify the terminal and find its contact details yourself, from its own website or a trade registry. Never use the numbers on the document.
  2. Ask the terminal operator to confirm the tank, the tenant and the product, within whatever their confidentiality rules permit.
  3. Contact the inspection company directly and ask them to confirm the report number, date and the party that ordered it.
  4. Match names end to end. The tenant on the TSA, the seller in the offer and the signatory on the contract should line up, or have a documented chain.
  5. Check the product grade against the location. A terminal that physically cannot store or load the grade is a decisive failure.
  6. Look at the file itself. Metadata, fonts and formatting inconsistencies are worth a second look.
  7. Use an independent party to inspect or sample before funds move, with payment tied to documents you have verified.
  8. Be wary of fees before delivery, including “POP verification fees”, “ICPO validation” or similar charges. Legitimate sellers do not charge a buyer to look at their product.

Why Documents Alone Are Not Enough

A real document can be used in a fraudulent deal. A genuine tank receipt can be shown by someone who has no right to sell what is in the tank. This is why verification has to cover who controls the product, not just whether the paper exists. For that, see our guide on how to verify a crude oil seller.

Takeaway

Real proof of product can be traced to a terminal, an inspector and a named owner, and each of them will confirm it when you ask directly. If the only way to confirm a document is to ask the person who sent it, treat it as unverified. If you have a POP package you are unsure about, BarrelBridge can review it before you commit.
