How to verify an edible oil supplier
By the Vanguard Verify desk · Published 2026-10-24 · Updated 2026-10-24
Short answer: confirm the seller is the refinery/crusher or holds a written mandate from one, that the oil exists in a named tank or production schedule, and that spec, inspection and payment terms are standard. Never pay before proof of product is verified bank-to-bank or through inspection.
Checks
- Company and refinery: registry record and LEI; the named refinery must exist and confirm the seller’s role.
- Product and spec: crude or refined; FFA, moisture and impurities, iodine value, colour; packing (flexitank, bulk vessel, bottles). It must match the inspection certificate.
- Storage or schedule: a tank receipt or loading schedule at a named terminal you can confirm with the terminal.
- Inspection: independent surveyor at loading (quality and quantity), confirmed with the surveyor directly.
- Payment: LC at sight or documentary collection; no “tank rental” or “dip test” fee paid to the seller before contract.
Red flags
- “Dip test” or “tank storage” fees demanded upfront.
- War-zone origin with no export permits.
- Same offer text sent by many unrelated companies.

FAQ
What is a dip test in edible oil deals?
A physical check of oil in a storage tank. A real dip test is arranged with the tank terminal and an independent surveyor; be careful when a seller asks you to pay them for it before any contract.
