Fuel trading moves quickly, but a rushed transaction can become expensive if the storage, inspection, transfer terms, or product documents are unclear. Tank-to-Tank Spot FOB trading is built around a simple idea: the product is already in an approved terminal, an independent party can inspect it, and the transfer happens under agreed Free on Board terms.
This guide answers the common questions buyers, mandates, brokers, and supply teams ask before entering a Tank-to-Tank, or TTT, Spot FOB fuel transaction. It covers how the process works, which ports are commonly supported, what inspection means, which products may be available, and how spot deals compare with long-term supply agreements.
This article is for general information only. Fuel transactions involve commercial, legal, operational, and compliance risk, so parties should use qualified advisers and conduct independent due diligence before committing to any trade.
Tank-to-Tank Spot FOB Fuel Trading FAQ
What is a Tank-to-Tank Spot FOB transaction?
A Tank-to-Tank Spot FOB transaction is a fuel trading method where petroleum products are stored at an approved terminal and transferred from one tank arrangement to another under agreed FOB terms. The product is usually already positioned at or near a major terminal before the buyer proceeds.
In this structure, the buyer is not relying only on a paper promise that fuel exists somewhere in a supply chain. The product should be tied to storage, documentation, terminal access, and independent inspection procedures agreed by the parties.
At a high level, a TTT Spot FOB transaction usually includes:
Product stored at an approved tank farm or terminal
Seller documentation showing product availability
Buyer review of the procedure, documents, and commercial terms
Independent inspection, often through SGS or an equivalent inspection company
Tank-to-tank transfer or title transfer according to the agreed procedure
Payment and release steps based on the contract
The word spot means the transaction is for a specific available quantity, rather than a long-term recurring supply obligation. The word FOB means Free on Board, a trade term that defines when responsibility and cost shift from seller to buyer. In fuel trading, the exact operational meaning must be clearly written into the contract, especially when the handover happens at a terminal.
A well-run Tank to Tank Spot FOB Fuel Trading FAQs process, in practical terms, should answer three questions before money moves: where is the product, who can verify it, and when does responsibility transfer?
How does the TTT process usually work?
No two fuel trades are exactly the same. Product, terminal rules, local law, and seller procedure can all affect the sequence. Still, most legitimate Tank-to-Tank Spot FOB transactions follow a logical path.
A typical deal flow may look like this:
Buyer submits interest
The buyer or buyer mandate confirms the requested product, quantity, destination or terminal preference, and transaction terms.
Seller issues commercial terms
The seller provides an offer, procedure, product details, pricing basis, terminal location, and any required documentation steps.
Parties review and sign the agreement
The buyer reviews the sales and purchase agreement, commonly called an SPA, along with the nominated procedure. Legal and compliance review should happen before signing.
Seller provides product and storage evidence
Depending on the procedure, this may include terminal-related documentation, product availability evidence, or other agreed papers. The buyer should verify documents through proper channels.
Independent inspection is arranged
SGS or an equivalent inspection firm may inspect the product for quantity and quality. The scope depends on the contract and terminal access rules.
Tank-to-tank transfer is completed
Once conditions are met, fuel is transferred according to the approved terminal procedure. This may involve a tank change, tank injection, title transfer, or other terminal-recognized action.
Payment and release take place
Payment terms should match the agreed milestones. After completion, the buyer receives the documents needed for lifting, storage control, or onward movement.
The safest procedures are clear, written, and verifiable. Vague steps create room for disputes. Each party should know what happens before inspection, what happens after inspection, and what documents trigger payment.
Which ports are supported?
TTT Spot FOB transactions are commonly associated with major international fuel hubs. The briefed network supports transactions at terminals including Rotterdam, Houston, Jurong, and Fujairah, subject to availability, seller terms, terminal rules, and compliance checks.
These hubs matter because they have deep fuel trading activity, storage infrastructure, marine logistics, and inspection access.
Port or hub | Why it matters in fuel trading |
Rotterdam | One of the world’s major petroleum and refined product trading centers, with extensive terminal and storage infrastructure |
Houston | A key U.S. energy hub connected to refining, storage, pipelines, and marine export activity |
Jurong | A major Singapore energy and petrochemical location with strong regional trading links |
Fujairah | A central Middle East bunkering and storage hub with strategic access to global shipping lanes |
Port support does not mean every product is always available at every terminal. Availability changes with seller inventory, storage schedules, refinery output, market demand, vessel planning, and local rules.
A buyer should confirm:
The exact terminal name
The product grade and specification
Current storage position
Inspection access
Transfer method
Loading or lifting options
Any local compliance requirements
Is SGS inspection available?
Yes. Independent inspection services such as SGS or an equivalent inspection company may be used according to the agreed transaction procedure. In fuel trading, independent inspection gives both sides a neutral reference point for product quantity and quality.
Inspection can help confirm:
Product grade
Quantity in storage
Density and basic product characteristics
Compliance with agreed specifications
Tank measurements, where access permits
Sampling and lab analysis, where required
SGS is widely known, but it is not the only inspection option. Other recognized inspection firms may be acceptable if the parties agree. What matters is that the inspector is independent, qualified, and allowed to access the terminal under the relevant procedure.
What inspection does and does not prove
Inspection is not a substitute for complete due diligence. It can confirm facts about the product at a specific time, under a specific scope. It does not automatically prove that every document is valid, that the seller has clear authority to sell, or that no legal restriction applies.
For that reason, buyers should treat inspection as one part of a broader verification process. A sound file may include corporate documents, authority checks, terminal confirmations, product documentation, inspection reports, compliance screening, and clear payment conditions.
When inspection should happen
The best timing depends on the contract. Some procedures call for inspection after the buyer has met certain preliminary steps. Others require seller-side evidence before any buyer commitment.
A strong procedure should explain:
Who appoints the inspection company
Who pays inspection costs
What the inspector must test or confirm
How samples are handled
How reports are shared
What happens if the product fails inspection
If these points are missing, ask for them before signing.
Which fuel products are available?
Product availability depends on the seller, terminal, market conditions, and timing. The product list may include EN590 10 PPM diesel, Jet A-1, D2 diesel, D6 virgin fuel oil, LPG, LNG, Mazut M100, Light Cycle Oil, and gasoline.
Each product has its own specification, handling rules, and buyer profile.
Product | Common use or market context |
EN590 10 PPM diesel | Road diesel specification commonly used in many markets, with low sulfur requirements |
Jet A-1 | Aviation turbine fuel used for commercial aircraft |
D2 diesel | Diesel fuel category often referenced in international trading, though specifications must be checked carefully |
D6 virgin fuel oil | Heavy fuel oil category often linked to industrial or marine use |
LPG | Liquefied petroleum gas, commonly propane, butane, or a mix, depending on specification |
LNG | Liquefied natural gas, requiring specialized cryogenic storage and handling |
Mazut M100 | Heavy fuel oil commonly referenced in fuel trading, with specification details varying by origin |
Light Cycle Oil | A refinery stream often used in blending or processing |
Gasoline | Motor fuel with strict grade, octane, and regulatory requirements |
The product name alone is not enough. A buyer needs the full specification sheet, also called a product spec or assay where relevant. For example, EN590 diesel should be reviewed for sulfur content, density, flash point, cetane number, distillation range, water content, and other parameters required by the buyer’s market.
Gasoline needs careful review of octane, vapor pressure, oxygenates, sulfur, and local environmental rules. Jet A-1 requires strict aviation fuel handling and quality controls. LNG and LPG need specialized infrastructure, safety systems, and shipping arrangements.
Do you support long-term contracts?
Yes. Both spot transactions and long-term supply agreements may be arranged, depending on buyer requirements and seller availability.
Spot deals work well when a buyer needs a defined quantity available now or within a short trading window. Long-term contracts suit buyers that need recurring supply, predictable scheduling, and agreed commercial terms over time.
The main difference is commitment.
Spot transaction | Long-term contract |
One-time or short-term purchase | Repeated supply over an agreed period |
Based on current seller availability | Based on seller capacity and delivery schedule |
Faster commercial focus | More detailed legal, logistics, and credit review |
Useful for urgent or opportunistic buying | Useful for steady consumption or resale planning |
A long-term agreement often needs more detail than a spot deal. The parties must agree on monthly quantities, tolerance levels, pricing formula, delivery schedule, payment instruments, inspection rules, default terms, and force majeure language.
A buyer should also confirm whether the first lift is treated as a trial shipment or as part of a binding long-term program. Many fuel relationships start with a spot transaction and expand only after both sides complete the first deal successfully.
What documents are common in a TTT Spot FOB deal?
Document names vary by seller and jurisdiction, but a serious transaction usually has a clear paper trail. The goal is not to collect a large stack of documents. The goal is to confirm the product, parties, authority, storage, and transfer process.
Common documents may include:
Corporate profile or registration documents
Buyer information sheet
Irrevocable corporate purchase order, often called an ICPO
Seller offer or full corporate offer
Sales and purchase agreement
Product specification sheet
Tank storage or terminal-related documents
Authorization to verify, where applicable
Injection report or transfer confirmation, where applicable
SGS or equivalent inspection report
Commercial invoice
Title transfer or product release documents
Document fraud is a known risk in commodity trading. Buyers and sellers should verify documents through official channels whenever possible. Terminal names, inspector names, banking instructions, and authority letters should all be checked before funds move.
What should buyers verify before proceeding?
A buyer should review more than price. A low price is not helpful if the procedure is unclear, the seller lacks product control, or inspection access cannot be arranged.
Key checks include:
Whether the seller has authority to sell the product
Whether the product is physically available at the stated terminal
Whether independent inspection is allowed
Whether the buyer can verify terminal-related documents
Whether the payment terms match the transfer risk
Whether the specification matches the buyer’s market
Whether sanctions, customs, and trade rules allow the transaction
Whether banking instructions are verified and consistent
A simple rule helps: no major payment should be made unless the buyer understands exactly what it receives in return, when it receives it, and how that step can be verified.
What are common warning signs?
Fuel trading attracts serious operators and bad actors. A careful procedure helps separate the two.
Watch for these warning signs:
Pressure to pay fees before product verification
Refusal to allow independent inspection
Documents that cannot be verified with the issuer
Seller procedures that change repeatedly
Claims of guaranteed allocation without evidence
Banking details that do not match the contracting party
Product prices far below normal market behavior without a clear reason
Terminal access claims that no terminal representative will confirm
Not every delay means a deal is bad. Terminals can be busy, inspectors may need scheduling, and compliance review may take time. The issue is not delay by itself. The issue is a lack of clear evidence, authority, and accountability.
How should pricing and payment be handled?
Pricing in fuel trading can be fixed, index-based, or negotiated against a market reference. The contract should state the product, quantity, price basis, currency, payment timing, and any included or excluded costs.
For FOB transactions, cost responsibility needs special care. The contract should say which party pays for inspection, storage extension, tank transfer fees, loading costs, port charges, documentation fees, and any other terminal-related expenses.
Payment terms should align with risk transfer. Common structures may involve payment after inspection, after title transfer, or after agreed documents are issued. The exact terms must be negotiated and documented.
Avoid informal payment instructions. Banking details should appear in the contract or formal invoice, and any change should be verified through a trusted channel.
What makes a TTT Spot FOB transaction work well?
A good transaction is not built on speed alone. It is built on clear roles, verifiable product, practical terminal access, and a procedure both sides can actually follow.
The strongest deals tend to share these traits:
A real product at a recognized terminal
A seller with authority and documentation
A buyer with clear funds and realistic requirements
An inspection company accepted by both sides
A written procedure with no vague milestones
Contract terms that match the physical transfer
Compliance checks before execution
Direct verification of key documents
Tank-to-Tank Spot FOB trading can be an efficient way to buy and sell petroleum products when storage, inspection, and transfer terms are clear. The process works best when every step can be verified and every obligation is written down.
The practical takeaway is simple: confirm the product, confirm the authority, confirm the inspection path, and confirm the FOB handover before moving forward. A disciplined process protects both buyer and seller, and it gives the transaction a better chance of closing cleanly. Tank-to-Tank Spot FOB Fuel Trading FAQ
