Vivo Energy Namibia, the unit of Vitol contracted to sell fuel products in the Southern African nation, said it was looking at alternative fuel supplies after a shipment of fuel that arrived in Walvis Bay port failed routine quality tests and was removed before circulation.
"Upon identification, the affected product was immediately quarantined and isolated," Vivo Energy Namibia said in a statement.
The company is conducting an investigation to determine the cause of the issue in collaboration with other unidentified parties, and did not provide a timeline for when replenishment supplies would arrive into the country.
Earlier, Discover Airline said aircraft operating flights to Frankfurt and Munich from Windhoek were being rerouted via neighbouring Angola to refuel before continuing their journeys.
"Lufthansa Group does currently face a local and temporary shortage in fuel with its suppliers at Windhoek airport," a spokesperson said of the shortages at Hosea Kutako International Airport.
Namibia, a global oil and gas exploration hot spot which hopes to produce its first oil by 2030, consumes approximately 100 million litres of petrol and diesel each month.
African countries are largely dependent on imported refined products, such as petrol, diesel and jet fuel from the Middle East, but have so far managed to avert any major supply disruption due to the Iran war.
In May, Energy Minister Modestus Amutse granted Vitol a three-month exclusive fuel supply deal to counteract fuel price volatility linked to the Iran war.
A Discover Airline spokesperson said it had to divert one flight on Wednesday to Frankfurt and another on Thursday. Discover has 10 flights per week to Frankfurt and Munich from Windhoek.
CARGO MAY BE AFFECTED AS TEAMS SCRAMBLE TO SECURE FUEL
The company's fuel procurement and ground staff were looking for solutions to reinstate normal supplies, Discover Airline said in a statement.
Lufthansa said in response to Reuters' questions that cargo shipments may be impacted.
The official opposition party, Independent Patriots for Change (IPC), said Lufthansa Cargo had notified its customers in writing on August 19 that it could not move cargo from Windhoek due to the shortages.
"The restriction runs to 23 August 2026 and, in the carrier's own words, that date is subject to change," said an IPC statement on Thursday.
Reuters saw a screenshot of the written notice but could not verify its authenticity.
In a statement on Thursday, the Namibia Airports Company said it was aware of Jet A-1 fuel-supply challenges at the country's main aviation gateway and that efforts were under way to minimise disruptions.
