Hong Kong’s Article 23 law: customs to alert police if visitors caught with seditious materials
- Customs chief Ho Pui-shan says department will also provide training so officers can better detect materials that endanger national security
- ‘I need to remind residents and tourists … when you go to a destination abroad, you need to know the customs clearance requirements of the place,’ she adds

Commissioner of Customs and Excise Louise Ho Pui-shan said on Saturday that her department would amend its internal guidelines and provide training on materials that endangered national security.
The legislation introduces 39 offences divided into five categories: treason; insurrection, incitement to mutiny and disaffection, and acts with seditious intention; sabotage; external interference endangering national security; and theft of state secrets and espionage.
Ho was asked on Friday how authorities would respond to tourists carrying old newspapers, such as copies of the now-defunct tabloid Apple Daily, or returning residents with books covering military matters in Hong Kong.
The customs chief only said there were no import and export restrictions on regular books, but urged visitors not to transport anything that could be in breach of the law.
