Introduction — The Most Misunderstood Rule in Petroleum Trade
Every day, buyers demand:
“Show me the POP now.”
“Send DTA/SGS/Q&Q before TSA.”
“Proof of product before any commitment.”
And every real petroleum seller — terminal client, refinery, or major trader — always responds:
“TSA first. POP later.”
Why?
Because POP (Proof of Product) is the highest-risk, highest-sensitivity documentation in the entire petroleum industry.
Releasing POP before TSA violates:
terminal compliance
insurance rules
ISPS port security
tank farm confidentiality
anti-fraud protocols
refinery corporate governance
This article explains exactly why legitimate sellers NEVER provide POP before TSA, and how buyers can understand the institutional logic behind this rule.
SECTION 1 — Understanding the Industry Reality Behind POP



1.1 POP is not “a document.” POP is a security-sensitive dataset
Real POP includes:
TSA (Tank Storage Agreement)
Tank number & terminal code
Pipeline Injection Receipt
SGS Q&Q report
ATC (Authority to Load)
Movement logs
Batch numbers
Vessel nomination (if TTT/TTV)
These documents reveal everything about the seller’s storage operations, including:
their tank positions
their inventory volumes
their pipeline activity
their shipping schedule
their relationship with the terminal
Releasing this information without legal protection would be catastrophic.
1.2 POP contains privileged operational data
Real petroleum companies (ENOC, ADNOC, NNPC clients, Vopak clients, Vitol, Trafigura) treat POP as classified operational data because it directly exposes:
storage strategy
crude logistics
pipeline flows
operational security
financial exposure
Leaks can result in:
cargo theft
tank hijacking attempts
fake resales
cyber-attacks
terminal compliance violations
This is why POP is strictly locked behind TSA.
1.3 Fraudsters exploit buyer ignorance
Fake sellers will send:
❌ Fake SGS
❌ Fake TSR
❌ Fake Q&Q
❌ Fake pipeline receipt
❌ Fake “terminal confirmation”
❌ Fake ATC
Because they know buyers do not understand the institutional rules that govern real tank access.
Real sellers do the opposite:
✔ They protect POP
✔ They release POP only after TSA
✔ They follow terminal protocols
✔ They comply with port security
SECTION 2 — Official Industry Reason: TSA Is the Legal Foundation for POP
2.1 TSA = Legal storage contract
A TSA (Tank Storage Agreement) is:
the contract between the seller and the terminal
proof the seller legally stores petroleum
the only document that proves tank access
the foundation for any POP release
Without TSA, the terminal cannot legally disclose:
tank numbers
batch references
ullage levels
movement logs
Therefore:
👉 No TSA = No POP.
👉 POP before TSA = Fake.
2.2 POP before TSA violates ISPS Port Security Code
POP reveals:
location of hazardous materials
tank coordinates
operational vulnerabilities
access points
Under ISPS, terminals must protect:
inventory data
tank IDs
operational logs
pipeline movements
restricted-access information
POP cannot be released without confirming:
the buyer is legitimate
the buyer has security clearance
a legal relationship (TSA) exists
2.3 Terminal operators do NOT allow POP release before TSA
Terminals such as:
Vopak (Rotterdam)
VTTI (Fujairah / Rotterdam)
Horizon / ENOC (Fujairah)
Oiltanking
Eurotank
do NOT authorize:
SGS access
DTA/UDTA
tank coordinates
pipeline data
ullage reports
Q&Q results
…without TSA in place.
If a seller releases POP before TSA → the document is fake or stolen.
SECTION 3 — NNRV Expert Analysis: The Real Logic Behind TSA → POP Sequence
Here is the institutional logic:
1️⃣ TSA proves that the seller is a real terminal client
Without TSA, the seller cannot legally store crude.
2️⃣ TSA authorizes buyer to inspect the product (via DTA/UDTA)
The terminal needs TSA to approve SGS entry.
3️⃣ TSA activates buyer’s security clearance at the terminal
Terminal assigns buyer a “recognized interest.”
4️⃣ TSA locks the tank under regulated commercial protection
Only then can terminal release:
POP
Q&Q
injection receipts
ullage data
5️⃣ TSA protects seller from fraudulent buyers
POP without TSA exposes seller to:
theft
re-routing
fake buyers reselling his crude
compliance breaches
6️⃣ TSA is the only legal basis for POP transfer
Terminal cannot work without TSA.
7️⃣ TSA triggers the POP release protocol
POP is typically released via data room:
TSA
DTA / UDTA
POP documents
SGS scheduling
DIP / Q&Q
Payment
Tank Take Over / TTT
This is the ONLY legitimate sequence.
SECTION 4 — Step-by-Step: Why POP Must Follow TSA (Not Before)
Step 1 — Buyer sends ICPO + KYC
Terminal screens buyer.
Step 2 — Seller submits TSA (redacted)
Confirms legal storage.
Step 3 — Terminal authorizes DTA/UDTA
Allows SGS access.
Step 4 — Buyer nominates SGS/Intertek
Inspection scheduling begins.
Step 5 — Terminal releases POP in secure portal
After verifying TSA.
Step 6 — DIP test / Q&Q
Independent analysis.
Step 7 — Payment (MT103 / TT / MT760)
Then title transfer / TTO / TTT.
POP appears only at Step 5.
Any POP offered before Step 5 is fraudulent.
SECTION 5 — 20 Questions Buyers & Sellers Ask
10 Buyer Questions
Can we receive POP before TSA? → No.
Is TSA always needed? → Yes for tanks.
Is POP before TSA ever real? → Never.
Can I identify tanks before TSA? → No.
Who issues TSA? → The terminal.
Can brokers get POP? → No.
What is the strongest proof? → TSA + DTA + injection receipt.
Does SGS confirm POP? → Yes after TSA.
What if seller sends POP early? → Fake.
Does TSA protect buyer? → Yes.
10 Seller Questions
Can I give POP early? → No.
Should I hide my tank numbers? → Until TSA is signed.
Can TSA be redacted? → Yes.
Is DTA enough? → No—needs TSA first.
Can buyers pressure early POP? → Serious buyers never do.
Should SGS work without TSA? → Impossible.
Can terminals release POP? → Only after TSA.
Does TSA show storage fee status? → Yes.
Can TSA be faked? → Yes—NNRV verifies.
Is TSA legally binding? → Yes.
SECTION 6 — Why These Rules Exist (Legal & Regulatory Framework)
POP is governed by:
ISPS Port Security Code
API MPMS petroleum measurement rules
ISO 8217/3170/3171
Terminal storage contracts
Insurance and liability clauses
SGS/Intertek protocols
This framework makes POP release before TSA illegitimate and illegal.
