A sudden surge in Chinese custard apple imports has raised serious security concerns in Taiwan, with sources confirming that shipments have more than tripled since March. The fruit, officially known as sugar apple or sweetsop, is being flown in through third-party routes, circumventing normal trade channels. Intelligence officials fear the shipments could be used to smuggle surveillance equipment or contraband, though no hard evidence has yet emerged.
Customs records obtained by this newspaper show a 340 per cent increase in custard apple imports from mainland China compared to the same period last year. The fruit arrives predominantly via Hong Kong and Macau, with final delivery points scattered across Taipei, Kaohsiung and Taichung. One senior official, speaking on condition of anonymity, said: ‘We are seeing patterns that do not fit legitimate agricultural trade. The quantities are too high, the logistics too complex. Something is off.’
Taiwan’s agriculture ministry insists the fruit is subject to rigorous phytosanitary checks, but security analysts point out that the real threat may be hidden inside the fruit itself. In 2022, a similar alert was raised over magnetic monopoles allegedly embedded in Brazilian nuts. Though that theory was later discredited, the lack of transparency around the custard apple supply chain is troubling. Documents from the Ministry of Economic Affairs show that importers are small, newly registered companies with no prior involvement in agricultural trade.
The timing is particularly sensitive. With cross-strait tensions at their highest in decades, any unusual economic activity invites scrutiny. Taipei has already accused Beijing of weaponising fruit exports before. In 2021, China blocked imports of Taiwanese pineapples, claiming insect infestations, which many saw as a political move. Now the flow appears to be reversed, and the question is why.
‘This is a classic cover for illicit goods,’ said a former intelligence officer familiar with trade-based money laundering. ‘You hide the real cargo inside a legitimate shipment. It’s been done with drugs, weapons, you name it. The custard apple is just the latest vehicle.’ He noted that the fruit’s thick skin and short shelf life make it an ideal container for small electronic devices or documents.
Taiwan’s Coast Guard has conducted random inspections of incoming shipments but lacks the resources to check every crate. Meanwhile, the National Security Bureau has declined to comment, citing operational confidentiality. A statement from the Mainland Affairs Council read: ‘We are aware of the reports and are taking necessary precautions. The safety of our people remains paramount.’
No one in government has explicitly accused Beijing of orchestrating a covert operation. But the silence from the Chinese embassy in Taipei speaks volumes. When asked about the import spike, a spokesman said only: ‘China-Taiwan trade relations are normal and mutually beneficial.’
The custard apple affair may yet prove to be nothing more than a quirk of the market. But in a region where every shipment is scrutinised for hidden threats, the burden of proof rests with those who dismiss the danger. This newspaper will continue to follow the money, and the fruit, until we get to the core of it.
