Customs officers at Bangkok's Suvarnabhumi Airport arrested a Chinese passenger on 31 October after finding 8,900 weight-loss injection pens in his two suitcases, the Customs Department said. The man, who was not named, had flown in from Dhaka, Bangladesh. Customs valued the pens at more than 5.34 million baht. [1], [2], [3]

According to Santanee Phairattanakorn, director of the Suvarnabhumi Airport Passenger Control Customs Office, the pens were not registered with or authorised by the Thai Food and Drug Administration. Customs said the attempted import breached the Customs Act 2017 and the Drug Act 1967, and that the passenger was detained for prosecution. [1], [3]
The pens are of the GLP-1 receptor agonist type, a class that includes liraglutide and semaglutide. Since 15 September 2026 they have been classed in Thailand as specially controlled medicines, available only on a doctor's prescription and from pharmacies, after they were found to be used for weight loss without proper medical evaluation and supervision. [2]
The Customs Department said GLP-1 medicines have previously been smuggled into Thailand through international passenger arrivals and other checkpoints, and that it has stepped up checks on them. The reports do not say whether the pens were genuine products imported without registration or counterfeits, or which brands they carried. [1]
