Confirmed / documented cartel / anti-competitive cases involving TotalEnergies

Period / Product / Market	What happened / Finding	Outcome / Sanction
Paraffin wax / slack wax cartel	As part of a group of petrochemical companies, Total (then predecessor of TotalEnergies) participated in a cartel in the paraffin- and slack-wax market — a “price-fixing and market-sharing” cartel covering many European countries. European Commission+2Reuters+2	In October 2008 the European Commission imposed a total €676 million fine on cartel members; Total was among the fined parties. Reuters+2European Commission+2
	Total challenged the fine; over appeals its liability was reduced somewhat but its involvement was upheld. Lexology+2MLex+2	Final fine after reductions remained substantial. MLex+1
Fuel-distribution / supply cartel in Corsica (2016–2023)	In 2025 the Autorité de la concurrence (France’s competition authority) found that TotalEnergies Marketing France and other firms colluded by reserving exclusive access to the only fuel-depots on the island (owned by a joint-depot company) for shareholders — thereby foreclosing non-shareholder competitors and harming competition. autoritedelaconcurrence.fr+2Reuters+2	TotalEnergies was fined €115.8 million (part of a total €187.5 million across the firms) for its role in this anti-competitive agreement. Reuters+2ChemAnalyst+2
Legal & appeal status — 2025 case	TotalEnergies publicly said it contests the decision, arguing the evidence does not show actual harm to competition or consumers, and announced it will appeal. TotalEnergies.com+2Reuters+2	The appellate process is pending. Reuters+1

Additional Allegations / Ongoing Investigations (or contested cases)

• There have been investigations or complaints involving TotalEnergies (or its subsidiaries) in other jurisdictions — for instance in Morocco: local authorities reportedly sent a notification of grievances to several oil companies including TotalEnergies for suspected anti-competitive practices in fuel distribution. energynews.pro+1
• In 2025, the Corsica ruling is the most recent public sanction. Given that TotalEnergies has indicated it will appeal, the final legal determination may evolve. TotalEnergies.com+2Reuters+2
• On a related note (though not strictly a “cartel” but “market manipulation”), a subsidiary of TotalEnergies was recently fined by a U.S. regulator for attempted manipulation of European gasoline futures. This shows that in addition to distribution-market collusion, the company has also faced scrutiny for trading-related misconduct. Energy Voice+1

Interpretation — What this means about TotalEnergies and cartels

• Cartel participation is real and dated: The paraffin-wax cartel — often dubbed the “wax cartel” — is a well-established example; participation was confirmed, fines imposed, and appeals concluded with Total being held liable.
• Recent antitrust enforcement: The 2025 Corsica fuel-supply case is a concrete example that enforcement against major energy companies continues — and that practices once perhaps tolerated or unnoticed are now more aggressively prosecuted.
• Mixed outcomes but persistent risk: While some activities are historic (e.g. wax cartel), others are fresh — and some remain contested. This suggests that involvement in cartel-type behavior isn’t merely historical but remains a regulatory risk for TotalEnergies.

Additional known cases involving TotalEnergies / Total

• Paraffin- and slack-wax cartel (1992–2005, decision 2008)

• The European Commission found in 2008 that Total (via Total France S.A. / Total Raffinage Marketing) participated in a cartel among paraffin-wax and slack-wax producers, fixing prices and sharing markets in the EEA. European Commission+2European Sources Online+2
• The cartel affected a broad range of products (paraffin wax — used in candles, packaging, rubber, adhesives, etc.) and involved fixing both prices and allocation of customers/markets. European Sources Online+2European Commission+2
• Total (and its subsidiary) was fined: the original 2008 fine was part of a total €676,011,400 against nine firms. European Sources Online+2Westlaw+2
• The matter was appealed: the General Court of the European Union confirmed the infringement and the fine (though reduced slightly to reflect precise duration) in 2013. be.schindhelm.com+2Eur-Lex+2
• Later further appeals were made (see case at EU’s top court), but key parts of the decision stood: the cartel and illegal price-fixing + market-sharing were confirmed. Eur-Lex+2MLex+2

So this is not a “recent allegation” but a historic, confirmed cartel case with final court validation.

• Fuel-distribution / supply cartel in Corsica (2016–2023 → 2025 fine)

• In November 2025 the Autorité de la concurrence (France’s competition authority) imposed a collective fine of €187.5 million on several companies — among them TotalEnergies Marketing France (TEMF) — for an anti-competitive agreement in Corsica’s road-fuel distribution sector. autoritedelaconcurrence.fr+2ICLG Business Reports+2
• According to the decision, a contractual clause (2016–2023) reserved access to the island’s only fuel depots — operated by Dépôts Pétroliers de la Corse (DPLC) — exclusively for its shareholders (TEMF, plus other firms), effectively blocking non-shareholder competitors from using the depots under fair conditions. autoritedelaconcurrence.fr+2ICLG Business Reports+2
• The authority judged this arrangement had “foreclosure effects”: non-shareholders were forced to buy fuel under disadvantaged conditions from their direct competitors, harming competition and ultimately consumers. autoritedelaconcurrence.fr+2ICLG Business Reports+2
• TotalEnergies Marketing France was fined €115.8 million — the largest share. autoritedelaconcurrence.fr+2ChemAnalyst+2
• TotalEnergies has announced it will appeal the decision before the Paris Court of Appeal. Reuters+2TotalEnergies.com+2

This is a very recent cartel/anti-competitive case, showing that regulatory scrutiny of fuel-market practices is still very much alive.

What I did not find (or could not confirm clearly)

• Beyond the two above, I did not locate credible public-record cases where TotalEnergies has been penalized for other cartels (e.g., international price-fixing in oil, chemicals, or other product lines) that are publicly attributed to them. In other words: no third confirmed, final cartel for which there is a public decision I can reliably cite.
• I found some allegations in secondary media or discussion (e.g., fuel distribution practices in other regions, or competition concerns in various markets), but nothing with the legal clarity of the two cases above.
• No large-scale recent EU Commission decision post-2008 seems to list Total/TotalEnergies as cartel offender outside of the Corsica case (until 2025). I checked major publicly available cartel-decision databases — and none show a third entry for Total between 2008 and 2025.

Conclusion: What this suggests about TotalEnergies’ cartel history

• TotalEnergies (or its predecessor, Total) has been involved in at least two major cartel/anticompetitive-practice cases: the wax cartel (1992–2005) and the Corsica fuel-depot cartel (2016–2023).
• The wax cartel shows that Supreme-level cartels can involve commodity/chemical markets (paraffin wax), not just fuel. That cartel resulted in multi-hundred-million-€ fines and survived court appeals.
• The Corsica case shows more recent behaviour involving distribution/infrastructure access rather than commodity-price fixing — a different kind of cartel-related abuse (foreclosure via exclusive depot-access).
• However — despite the size and global reach of TotalEnergies — there are no many published cartel judgements against it. That doesn’t necessarily mean there were no other questionable practices — but if so, they were either never pursued, never proven, or not made public under cartel-enforcement procedures.

Confirmed non-EU matters involving TotalEnergies

1) Morocco — fuel-market settlement (2023)

• What: Morocco’s Competition Council reached a settlement with nine fuel distributors over suspected price-fixing / anticompetitive practices in the retail fuel market. TotalEnergies Marketing Maroc was one of the companies named in the process and publicly acknowledged the agreement.
• Outcome: Collective settlement/fines ≈ MAD 1.84 billion (reported ≈ US$180M / ~€166M total across the firms). TotalEnergies Marketing Maroc recorded the financial impact in its 2023 results. Concurrences+1

2) United States — CFTC enforcement against TOTSA (TotalEnergies Trading) for attempted market manipulation (2024)

• What: The U.S. Commodity Futures Trading Commission (CFTC) found that TOTSA TotalEnergies Trading SA attempted to manipulate European gasoline futures in 2018 (selling physical product at cut-rate levels while holding large short futures positions). This is trading-market manipulation (not a classic cartel among competitors for price fixing), but it is a major cross-border anticompetitive/market-integrity enforcement action.
• Outcome: Civil penalty: USD $48 million (settlement ordered by the CFTC). cftc.gov+1

3) Other non-EU activity / investigations — limited public findings

• I searched databases and competition-news outlets for confirmed cartel decisions involving TotalEnergies in Latin America, Sub-Saharan Africa (outside Morocco), Asia and Oceania. Beyond the Morocco settlement and the CFTC action, I did not find additional public, final cartel rulings (i.e., formal findings of price-fixing/cartel behaviour with fines) naming TotalEnergies or its main local operating subsidiaries in those regions. (There are many competition complaints, merger filings and routine probes in energy markets worldwide, but most do not result in public cartel findings naming TotalEnergies.) ONE+1

Quick interpretation / takeaways

• There are confirmed non-EU enforcement actions involving TotalEnergies: notably the Morocco fuel settlement (2023) and the CFTC market-manipulation penalty (2024). Both are public, enforceable actions and appear in regulator press releases and major press coverage. Reuters+1
• The CFTC case is specifically about attempted manipulation of derivative markets (trading conduct), which differs legally from cartel price-fixing between competitors — but both are anticompetitive and enforcement-relevant. cftc.gov
• Outside those items, I did not locate many other confirmed cartel rulings from non-EU jurisdictions that publicly name TotalEnergies; if further cases exist they may be in confidential settlement records, pending investigations, or in jurisdictions with limited public disclosure.
