The LNG destination clause and the diversion question

Destination terms look like a drafting preference until a cargo needs to move. Then they decide who may reroute it, who approves, and who keeps the margin.

What does an LNG destination clause actually control?

It controls three things. First, whether the buyer may deliver a cargo anywhere other than the named destination, and whether that requires consent or merely notice. Second, how any economic gain from the rerouting is shared between buyer and seller, usually through a profit-sharing formula with defined cost deductions. Third, the procedural duties that attach to a diversion, including notice periods, information the buyer must provide, and reporting after the event. Delivery terms matter here: destination restrictions in free on board arrangements have attracted sustained competition law scrutiny, while delivered arrangements leave routing with the seller.

Key takeaways

  • ✓Consent-based and notice-based destination clauses create very different operational workloads after signature.
  • ✓Profit-sharing formulas turn on cost deduction definitions, which is where most diversion disputes actually sit.
  • ✓Destination restrictions on free on board sales have drawn competition law scrutiny in several jurisdictions.
  • ✓Diversion duties are recurring and event-driven, so they belong in an obligation register rather than a trader’s notes.

Destination provisions in liquefied natural gas sale and purchase agreements are among the most negotiated and least administered terms in energy contracting. They are negotiated hard because they determine who captures the value when market conditions shift between the signing of a long-term agreement and the loading of a particular cargo. They are poorly administered because the duties they create are infrequent, and infrequent duties live in people rather than systems.

The commercial logic is straightforward. A seller selling into a specific market wants to prevent its own cargoes reappearing as competition in a higher-priced market. A buyer that has paid for a cargo and taken title wants the freedom to send it wherever the economics are best. The resulting clause is a compromise, typically allowing diversion subject to conditions and sharing the upside.

Where this gets interesting is that the compromise generates real operational work, and the work arrives suddenly. A cargo becomes divertible when someone spots an arbitrage, and from that moment a notice period is running, information has to be assembled and a calculation has to be agreed. This article is about the terms that drive that work and how to hold them somewhere usable.

Five terms that decide how a diversion runs

A destination clause is rarely a single sentence. It is a small cluster of provisions, and the interaction between them determines whether a diversion is a routine commercial decision or a negotiation under time pressure.

  • The restriction itself, whether destinations are fixed, flexible within a region, or free, and whether the limit attaches to the cargo or to the annual programme.
  • Consent or notice, whether the seller must approve, with what response time, or whether notice within a stated period is sufficient on its own.
  • The profit-share formula, the price comparison basis, the ratio, and critically the exhaustive list of costs the buyer may deduct before the split.
  • Notice content and timing, what the notice must contain and how far ahead it must be served, since an incomplete notice frequently restarts the clock.
  • Post-diversion settlement, the deadline for a final statement with supporting evidence and the period for payment or credit of the shared gain.

Read together, these five determine the answer to the only question a trading desk asks in the moment: can this cargo move, by when must we tell them, and what does the economics look like after the split. If the answer takes a day to assemble from the agreement, the arbitrage has usually closed.

The cost list is where diversions go wrong

A profit-share formula that deducts reasonable additional costs invites a dispute every time it operates. An exhaustive list, naming incremental voyage cost, boil-off, port and canal charges, demurrage, additional insurance and any agreed administrative allowance, converts an argument into an arithmetic exercise. Agreeing the list at drafting costs an hour; disagreeing about it after discharge costs considerably more.

Holding the terms where they can be used

Destination and diversion provisions are a good test of whether contract administration is working, because they are low-frequency, high-value and time-bound. Five practices make the difference.

  • Extract the destination terms as fields. Restriction type, consent or notice, notice period, profit-share ratio and settlement deadline held as searchable fields across the LNG portfolio rather than read from the document each time
  • Pre-build the notice template. The clause specifies the content; the template should mirror it exactly, so a notice served under pressure is complete and the period starts running on the first attempt
  • Instantiate the obligations on diversion. A diversion event creates a defined set of duties with dates: notice served, seller response, discharge confirmation, final statement, settlement. Instantiate them from a template rather than tracking by email
  • Collect settlement evidence as it arises. Port invoices, bunker and demurrage statements and price references are easiest to capture in the week they are issued. Attaching them to the open obligation avoids a reconstruction later
  • Review the clause population annually. Destination terms change as portfolios and market structures change. An annual read across the portfolio shows where restrictions have become commercially or legally awkward before a counterparty raises it

A five-step roadmap for administering destination terms

Step 1, inventory the destination terms across the portfolio

Build a single view of every LNG agreement with its restriction type, consent or notice basis, notice period, share ratio and settlement deadline. Most portfolios turn out to contain three or four distinct patterns rather than a different arrangement per contract, which simplifies everything downstream.

Step 2, confirm the delivery term interaction

Record whether each agreement is on a delivered or free on board basis, because the two put routing responsibility in different hands and carry different legal exposure on destination restrictions. This field is also the first thing counsel asks for when assessing a clause.

Step 3, standardise the cost definition at renewal

Where formulas rely on open-ended cost language, propose an exhaustive list at the next renewal or amendment. Sellers and buyers both benefit from removing the argument, which makes this an unusually easy negotiation to open.

Step 4, template the diversion workflow

Define the obligation set a diversion creates, with owners by role, dates derived from the event and required evidence per step. Tested once on a historical diversion, the template will handle the live ones without anyone reading the agreement under pressure.

Step 5, report diversions and settlement ageing

Track diversions per period, the gain shared, and how long settlement statements take against their contractual deadline. Ageing is the useful metric, because slow settlement is where counterparty relationships and recovery both quietly degrade.

What good administration is worth here

The value is concentrated in two places. The first is speed: a desk that can answer the divertibility question in minutes rather than hours captures opportunities that would otherwise close, and that difference is measured in the price spread on a full cargo. The second is settlement discipline: shared gains that are calculated late, from reconstructed cost data, are routinely settled at less than they should be, simply because the evidence has decayed. Neither of those requires sophisticated tooling. They require the terms to be structured and the duties to be instantiated, which is the same discipline applied to take-or-pay and minimum volume commitments.

Diversion duties and their evidence

The table sets out the obligation sequence a diversion creates, with a workable owner and the artefact each step should produce. Dates are expressed relative to the event because that is how they operate in practice.

Destination clauses reward preparation in a way that is unusual among contract terms, because the window in which they matter is short and the information they require is specific. A portfolio where restriction type, notice period, share ratio and settlement deadline exist as fields, and where a diversion instantiates a known set of duties, handles these events as routine. A portfolio where all of that lives in the agreements handles them as emergencies, and settles them late. Operators already running structured obligation management for energy and mining can add the diversion template to the register they have.

FAQ

Destination and diversion questions, answered

What is the difference between a consent clause and a notice clause? +
A consent clause requires the seller to agree before a cargo is rerouted, which gives the seller control and creates a decision with a response time the contract should specify. A notice clause allows the buyer to divert provided it informs the seller, usually with a minimum period and specified information. The operational difference is substantial: consent clauses generate approval workflows with deadlines on both sides, while notice clauses generate a reporting duty and a profit-share calculation.
Why do destination restrictions attract competition scrutiny? +
Because a restriction that prevents a buyer reselling a cargo it has taken title to can function as a market partitioning arrangement. Competition authorities in several jurisdictions, notably Japan, have examined destination clauses in free on board LNG sales and found them problematic where title and risk have passed to the buyer. Delivered arrangements sit differently, since the seller retains responsibility for shipping. Counsel should assess any specific clause against current law in the relevant jurisdictions.
How do profit-sharing formulas usually work? +
The gain is calculated as the price achieved at the alternative destination less the price that would have applied at the original destination, less defined costs, with the net split in an agreed ratio. Everything contentious lives in the cost definition: additional voyage costs, boil-off, port and canal charges, demurrage, insurance and whether the buyer may recover any trading or administrative margin. A formula with an exhaustive cost list is far easier to administer than one relying on reasonable costs.
What information should a diversion notice contain? +
The cargo and vessel identification, the original and proposed destinations, the revised arrival window, the basis on which the buyer is entitled to divert, and the preliminary profit-share calculation with its inputs. Specifying the content list in the clause prevents the common outcome where a notice is served on time but is incomplete, and the parties then disagree about whether the notice period ever started running.
What has to happen after a diversion completes? +
A final profit-share statement with supporting evidence, usually within a defined period after discharge, and payment or credit within a further period. The supporting evidence is the part that slips: port invoices, bunker costs, demurrage statements and price references need to be collected while they are current. Making the statement a dated obligation with the required attachments listed turns it into routine work rather than a reconstruction exercise months later.
Do these clauses need tracking if diversions are rare? +
Yes, and arguably more so. A duty exercised twice a year is one nobody has built muscle memory for, so the notice period, the information requirements and the statement deadline all have to be looked up under time pressure. Holding the terms as fields and the duties as templates means the first hour of a diversion is spent on the commercial decision rather than on reading the agreement to find out what is required.
