1. Demand for Upfront TSA Extension Payments
The scam: The seller claims a vessel or tank is ready in Rotterdam, Houston, or Fujairah, but requires the buyer to pay for 3 to 7 days of “tank extension” or “storage fees” before granting a Dip Test.
Due-diligence position: Verify storage arrangements directly with the named terminal and reject unverified third-party advance-fee demands.
2. Fixed Pricing Models Instead of Market Benchmarks
The scam: Offers use a rigid low fixed price per metric ton regardless of daily market movement, or unusually large fixed discounts.
Due-diligence position: Confirm whether pricing is tied to a recognized benchmark such as Platts or Argus and whether the commercial formula can be independently verified.
3. Fake Full Corporate Offers & Unverified Intermediaries
The scam: Generic letterheads, free email providers, unverifiable company details, tax IDs or registrations.
Due-diligence position: Verify legal entity records, domain ownership, corporate communications and counterpart authority before relying on offer documents.
4. Unverifiable DTA & Fake POP
The scam: Falsified POP documents, outdated inspection reports or DTA forms linked to pre-payment or non-refundable deposits.
Due-diligence position: Seek independent verification with the terminal operator and inspection company using independently sourced contact details.
5. Upfront Authorization or Registration Fees
The scam: Demands for “passport authorization,” “vessel allocation registration,” or “buyer onboarding” fees before contract execution.
Due-diligence position: Treat unexplained pre-contract cash demands as a major risk indicator and verify all payment instructions through formal counterpart and banking channels.
