Where EN590 Chain Trades Fail, and at Which Step
A tank-held EN590 chain trade follows a recognisable sequence. Most of the trades which fail do so at one of six steps, and the step determines the cost.
The point of mapping the sequence is not to catalogue misfortune. Failures at early steps are cheap and failures at late steps are expensive, so the discipline which pays is the discipline applied first.
Step one. Establishing the counterparty is a principal
The first question is whether the party offering product controls it. A great deal of enquiry in this market originates from parties representing other parties, sometimes several removes from anyone with title.
The failure at this step is invisible and costs only time, which is why it goes uncorrected. A buyer spends weeks in correspondence with a party who was never able to sell, and learns nothing about why.
The test is direct. Ask who holds title to the product, in whose name the storage stands, and whether the party in front of you is the seller or an intermediary. An honest intermediary answers plainly and is frequently useful. A party who avoids the question has answered it.
Step two. Verifying the product exists
Product held in tank is evidenced by a storage receipt issued by the terminal. A document supplied by a seller, which the terminal did not issue and will not confirm, is not evidence.
Verification runs to the terminal on contact details obtained independently. Ask the terminal to confirm from its own records rather than to confirm a copy you send. Where direct confirmation cannot be obtained, treat the inability as a decisive fact rather than as an administrative delay.
A failure here costs more than time, because it usually arrives after commercial terms are agreed and after both sides have told their own management the trade is progressing. The pressure to proceed is at its highest at exactly the point where the evidence is weakest.
Step three. Establishing the buyer's storage position
A buyer receiving product in tank needs a storage agreement at an approved facility in its own name. Without one there is nowhere for the product to go and no standing to instruct anything.
The failure at this step is the most common structural failure in chain trades, and it is entirely avoidable. It arises because a buyer assumes the transfer mechanism will be a takeover of the seller's existing position, and learns late the terminal will not offer one.
Where a takeover is unavailable, the trade becomes a physical transfer, which requires the buyer to hold storage and requires two terminals to coordinate. Neither is quick. A trade restructured at this point loses the timeline it was built on, and in a market where sellers claim other buyers are waiting, a lost timeline frequently means a lost trade.
Step four. Confirming the onward movement
In a chain, the buyer of the first leg is the seller of the second, and the product has to be capable of moving on, which requires the receiving terminal to accept it and both facilities to agree a transfer.
The confirmation to obtain is specific rather than general. Not whether inter-terminal transfers are possible, which they usually are, but whether these two named facilities have coordinated a direct transfer, and on what notice. Terminal relationships vary and an operation which is routine between two facilities is a project between two others.
A failure here strands product in a tank the intermediate party is paying for, with a committed onward buyer and no route to deliver. This is the most expensive failure in the sequence, because storage costs accrue while the problem is solved.

Step five. Sequencing payment against title
The commercial structure has to specify what happens in what order, and the ordering decides who carries risk in the intervals.
Three questions settle it. When does title pass, and against what event. When does payment fall due, and against what document. And what does each party hold during the interval between the two.
The failure here is rarely dramatic and frequently expensive. A buyer paying against a document which does not transfer control has paid for a promise. A seller releasing control against a payment instrument which has not cleared has extended credit without deciding to. Both positions are common and both are correctable at the drafting stage for no cost.
Step six. Quality and quantity on transfer
Product moving between tanks is measured at both ends and the figures rarely agree exactly. Line displacement, tank calibration, temperature correction and free water all sit in the gap.
The contract has to name which measurement governs, who appoints the inspector, and what tolerance is accepted before an adjustment arises. Where it does not, the parties find their disagreement after the product has moved and neither has any leverage.
Quality on transfer carries the same structure. The receiving terminal applies its own acceptance criteria, and a cargo which meets contractual specification and fails the terminal's receipt criteria is a problem with no obvious owner. Establish the receiving facility's criteria before the transfer rather than during it.
The pattern across all six
Every step in the sequence has the same shape. A confirmation is available, obtaining it takes days, and proceeding without it is faster.
The market rewards speed, and the pressure to skip confirmations is applied by the party who benefits from them being skipped. The whole mechanism is exactly this. There is no sophistication in it.
The defence is preparation rather than suspicion. A buyer who already holds a storage agreement, already knows which terminals coordinate, and already has a verification routine performs the confirmations in parallel with the commercial discussion rather than after it. The same trade closes faster, not slower, because the work was done before the opportunity arrived.
The argument for treating procedure as capability rather than as overhead. In a market where the constraint is availability, the buyer able to move without pausing to build the foundations is the buyer who gets the cargo.
There is a second reason the preparation pays, which is reputational. Terminals, inspectors, agents and genuine sellers all operate inside a small professional community and they talk to one another. A buyer who verifies properly, asks sensible questions and closes what it starts becomes known as such, and the market brings opportunities to parties it expects to perform.
The opposite reputation forms equally quickly. A buyer who circulates enquiries widely, takes offers to the point of documentation and withdraws repeatedly is filtered out by exactly the counterparties worth dealing with, and left with the ones who have nothing better to do. The outcome looks like bad luck from the inside and is entirely self-inflicted.
The sequence in this piece is a defence against loss. It is also the operating standard which gives a buyer access to product in a market where product is the scarce thing.
One practical note on sequencing. The six steps run in order because each gates the next, and the temptation in every live opportunity is to run them in parallel to save time. Some parallelism is fine. Running commercial terms ahead of storage verification is not, because it commits the buyer psychologically before the facts are in, and the whole difficulty in this market is the pressure to proceed once a trade feels real.
Keep the commercial discussion explicitly conditional until the first four steps are complete, and say so plainly to the counterparty at the outset. A genuine seller understands the condition. Everyone else objects to it, which is the information the condition was there to produce.
