When a Fuel Supplier Ceases Trading: Recovering CORSIA Records From a Closed Business
· DSTechnoverse · CORSIA & Carbon Markets
A supplier that has wound up, been acquired or changed systems takes its records with it. Where those records actually go, who can still be asked, and what to do when the answer is nobody.
Fuel supplier records outlast the operator's own copies more often than not, which is why the standing advice on a data gap is to ask the supplier first. That advice fails in one situation: the supplier no longer exists.
Suppliers wind up, get acquired, exit a station, or migrate to a new system and archive the old one badly. Each of these breaks the retrieval path in a different way, and the recovery route differs accordingly.
Where the records actually go
| What happened to the supplier | Where records typically survive |
|---|---|
| Acquired by another company | Transferred to the acquirer, often in an archive |
| Merged into a group entity | Held by the surviving entity |
| Wound up solvently | With the liquidator, then possibly destroyed after a period |
| Insolvent liquidation | With the insolvency professional; access is possible but slow |
| Exited the station, still trading | Still with the supplier — this is the easy case |
| System migration | Legacy system archive, or an export file |
| Franchise or agent arrangement | With the local agent, not the brand owner |
The last row catches people out. Fuel at many Indian stations is supplied under a brand but delivered by a local agent or concessionaire. The brand's head office may have no record of individual uplifts while the local agent has a complete paper file. Ask at the station, not only at the corporate level.
The system migration case is the most recoverable and the most often abandoned. A supplier that moved platforms three years ago usually retains a legacy export somewhere; the person who answers the phone in customer service will not know that, and the request needs to reach someone in IT or records management.
The escalation path
1. The station or local agent. Whoever physically supervised the uplift. Fastest route and frequently sufficient.
2. The supplier's regional office. Where the local agent has also gone, or was never the record holder.
3. The acquirer or successor entity. For acquisitions and mergers. Records transfer with the business; finding who now holds them takes persistence rather than legal process.
4. The insolvency professional or liquidator. For a wound-up entity. A written request explaining the regulatory purpose is usually met, though timelines are slow — allow several weeks.
5. The airport operator. In some cases the airport holds fuel throughput or concession records that corroborate quantity even where the supplier's docket is gone.
6. Your own bank and accounts payable. Payment references, purchase orders and delivery acknowledgements sometimes carry quantity detail the summary invoice omitted.
Each step should be documented with the date, the person approached and the outcome — that record is what supports a substitution later if every route is exhausted.
When the answer is genuinely nobody
At some point the search ends. The procedure then follows the ordinary substitution hierarchy, with two additional expectations because the primary source is permanently unavailable rather than temporarily unobtainable.
| Additional expectation | Why |
|---|---|
| More thorough documentation of the search | The gap is permanent; the file must show why |
| Stronger corroboration from surviving sources | Technical logs, dispatch records, payment records |
| More explicit conservatism | Nothing can later contradict the estimate |
| Disclosure in the emissions report | Named as a permanent gap, not a pending one |
The corroboration point matters. Where a supplier record is gone forever, a verifier will want to see that the substituted figure is consistent with two or more independent sources — typically the technical log and the payment record — rather than modelled from aircraft type alone. Two independent corroborating sources agreeing with a modelled figure is a substantially stronger position than a model standing on its own.
The general substitution rules are in CORSIA data gap procedures.
Preventing the dependency
The structural lesson is that an operator relying on a third party to hold its regulatory records has an uncontrolled dependency. Four controls remove it, and none is expensive.
| Control | Effect |
|---|---|
| Take a copy at the point of uplift | The operator holds primary evidence itself |
| Monthly data pull into the operator's own system | Records survive the supplier |
| Retention clause in the supply contract | Five years, with a right to request |
| Annual archive export | A snapshot outside any live system |
The first is the decisive one. An operator that captures the uplift docket into its own system at the time of the uplift — a photograph on a phone into a defined folder is sufficient — never needs to ask anyone for anything. Everything else in this article describes the recovery process for records the operator chose not to keep.
For contracting practice see CORSIA fuel supplier data coordination; for the systems that hold the copies, CORSIA data systems and automation; and for the reconstruction hierarchy, missing fuel uplift records. Record-keeping expectations are set out in the ICAO CORSIA implementation elements.
Frequently Asked Questions
What happens to fuel records when a supplier ceases trading?
They usually survive somewhere — with an acquirer, a successor entity, a liquidator, a local agent, or in a legacy system archive. The retrieval path differs by what happened to the business, but total loss is less common than operators assume.
Can records be obtained from a liquidator?
Generally yes. A written request explaining the regulatory purpose is usually met, though insolvency professionals work to their own timelines and several weeks should be allowed. Document the request and the response either way.
Who holds fuel records at a station supplied under a brand?
Frequently the local agent or concessionaire rather than the brand's head office. Asking at corporate level may return nothing while a complete paper file sits at the station. Always ask locally as well.
What if a supplier migrated to a new system?
A legacy archive or export usually exists. Front-line customer service will not know about it, so the request needs to reach records management or IT. This is among the most recoverable situations and the most often abandoned prematurely.
What does a verifier expect when a record is permanently unavailable?
A documented search showing every route attempted, corroboration from two or more independent surviving sources rather than a model alone, explicit conservatism in the estimate, and disclosure in the emissions report as a permanent rather than pending gap.
How can this dependency be avoided altogether?
Capture the uplift docket into the operator's own system at the time of uplift — even a photograph filed to a defined location is sufficient. An operator holding its own primary evidence never needs to trace a supplier's records at all.
