Introduction — Why Most Buyers Misinterpret SGS and Lose Millions
In petroleum trading (EN590, Jet A1, D6, Crude, LPG, LNG), SGS reports determine:
Whether the product meets specification
Whether the deal continues or collapses
Whether title transfers
Whether payment (MT103/LC) is released
Whether the buyer can resell or ship legally
Yet 90% of buyers do not know how to read SGS properly.
They only look at:
Density
Sulfur
Flash point
But real professional traders analyze:
Temperature corrections
Density @ 15°C vs observed density
Water content
Contamination markers
CFPP (Cold Filter Plugging Point)
Metals / additives
Sediment
Microbial presence
Kinematic viscosity
Actual vs contractual parameters
Whether results are terminal-verified
This article will teach you everything a refinery-level trader checks inside an SGS report—so you never get manipulated, scammed, or misled again.
SECTION 1 — Understanding the SGS Report: What It Actually Is
1.1 SGS Is the World Standard for Q&Q (Quantity & Quality)
SGS is the global benchmark for independent petroleum inspection.
When you receive an SGS report, you’re seeing:
Laboratory certification
Terminal-derived measurements
Legal evidence for quality
Basis for commercial settlement
Proof for payment release
Anchor document for title transfer
SGS is accepted in all major terminals:
Rotterdam
Fujairah
Hou…
Jurong
1.2 The Two Parts of Every SGS Report
A real SGS report always includes:
1. Quantity Section (Q)
Ullage / innage
Temperature
Observed volume
Density @ observed
Density @ 15°C
Correction Factor (CTL/CPL)
Net Standard Volume
2. Quality Section (Q)
Grade-specific tests such as:
Sulfur content
Flash point
Water %
Viscosity
Aromatics
Contaminants
Freeze point (Jet A1)
Pour point (diesel)
Most amateurs only read the second part.
Professionals read both as one legal instrument.
1.3 Why “Looking Only at Density” Is a Red Flag
Many inexperienced traders say:
“Density is correct, so product is good.”
“SGS matches spec, so we proceed.”
But a professional trader checks:
Measurement basis
Temperature variation
Consistency with port/refinery grade
Whether sulfur + aromatics combination matches grade
Whether water + sediment + contamination meet contract annex
This is where fake SGS reports fail instantly.
SECTION 2 — How to Read an SGS Report Like a Professional (A–Z Breakdown)




Below is the complete technical interpretation of each SGS parameter.
2.1 Density (Observed & @ 15°C)
What buyers look at:
Whether density matches EN590 spec (820–845 kg/m³).
What professionals look at:
✔ Density @ 15°C (reference base)
✔ Change between observed and corrected density
✔ Consistency with refinery source
✔ Variation that indicates contamination
If observed density significantly differs from corrected density → heating/cooling manipulation or product blending.
2.2 Sulfur Content
EN590 requirement = 10 ppm max.
Jet A1 = 3,000 ppm max, typically < 500 ppm.
Professional analysis:
High sulfur = off-spec
Too low sulfur (<4 ppm) suggests FAME blending
Sulfur patterns indicate refinery origin; mismatch reveals fraud
2.3 Flash Point
EN590 minimum flash point: > 55°C
Jet A1: 38°C minimum
Professional interpretation:
Low flash point → contamination with lighter fractions
High flash point → product aged or oxidized
2.4 Water & Sediment
Water must be ≤ 200 mg/kg for EN590; Jet A1 must be virtually dry.
Professionals check:
Water in mg/kg vs volume%
Microbial contamination indicators
Sediment levels showing pipeline contamination
2.5 CFPP (Cold Filter Plugging Point)
Critical for cold regions.
EN590 CFPP depends on climatic class:
Class A: +5°C
Class F: –20°C
Class 0 to Arctic grades vary accordingly
Professional interpretation:
CFPP must match contract grade + destination climate.
CFPP mismatch → product is not suitable for destination.
2.6 Viscosity
Viscosity issues = contamination or blending with heavy fractions.
Professionals detect:
Thicker product = contamination or aging
Lower viscosity = kerosene infiltration
2.7 Appearance (Visual Check)
Professionals never ignore:
Color
Cloudiness
Suspended solids
Layering
Odor
A simple visual discrepancy exposes 70% of fake SGS documents.
2.8 Remnant Additives (FAME, Lubricity, etc.)
FAME % must be within spec (<7%).
High FAME in Jet A1 = catastrophic contamination.
2.9 Metals & Contaminants (Jet A1)
Jet A1 checks for:
Sodium
Potassium
Calcium
Lead
Fuel lubricity
Freeze point
These are crucial for aviation safety.
2.10 Compare SGS vs Contract Specification Annex
Professionals overlay the SGS values onto the contract’s technical annex.
If any single value is out of tolerance → product is non-compliant.
SECTION 3 — NNRV Expert Analysis: The Hidden Details Amateurs Always Miss
3.1 The SGS Date & Time Must Match Tank Farm Log
Fake SGS reports often:
Have wrong dates
Mismatch terminal timestamp
Use non-existent tank numbers
Check SGS date vs:
DIP test
DTA issuance
Pumping schedule
Tank movement logs
3.2 SGS Location Verification
A real SGS report always contains:
Terminal name
Tank number
Sample point
Inspector name
Certificate number
Missing = fraudulent.
3.3 Serial Number Traceability
SGS report numbers are traceable via SGS internal system.
NNRV verifies serial numbers to eliminate recycled SGS.
3.4 “Perfect” SGS Values Are a Red Flag
Example:
SGS shows exactly perfect density, sulfur, flash point and appearance.
Real SGS always has natural variation.
Perfect numbers → fabricated.
3.5 Documentation Chain Verification
Professional traders verify:
DTA → DIP → Q&Q → SGS
All must align sequentially
All must match tank farm records
If one document doesn’t fit → fake seller.
SECTION 4 — Step-by-Step Guide: How to Analyze an SGS Report in 10 Minutes (Professional Workflow)
Step 1 — Authenticate the SGS certificate number
NNRV or SGS portal.
Step 2 — Check tank farm and terminal details
Ensure all identifiers match TSA/DTA.
Step 3 — Verify density @ 15°C
Should match contract grade.
Step 4 — Check sulfur first (always)
Disqualifying parameter.
Step 5 — Compare CFPP to contract grade
Cold-region buyers: critical.
Step 6 — Verify flash point and viscosity
Indicate contamination.
Step 7 — Validate water/sediment
Aging or contamination risk.
Step 8 — Compare with contract’s technical annex
Every value must be within tolerance.
Step 9 — Confirm inspector signature & seal
Fake SGS fails here.
Step 10 — Reconcile SGS quantity with terminal logs
Quantity must match DIP test.
