In September, customs officials seized more than 30,000 litres of smuggled fuel valued at over HK$1 million (US$127,000). The operation involved the raid of an illicit motor spirit storage site and the seizure of modified vehicles used for smuggling.

Investigators stated that criminals are using modified trucks and private cars with enlarged fuel tanks to transport fuel across borders. The high retail price of petrol in Hong Kong, which reached about HK$34.60 per litre this week, contributes to the growing risk taken by smugglers and buyers.

Authorities also highlighted the fire and explosion risks associated with the seized vehicles, which were described as unventilated. The disruption of global shipping routes and energy supplies, particularly through the Strait of Hormuz, has led to record high diesel prices and increased freight and insurance costs in Hong Kong.
