Meat, poultry and eggs (raw or not fully cooked)
A health certificate from the place of origin or permission from the Hong Kong government is required. This applies to vacuum-packed, foil-wrapped and frozen products too, and to foods that are not thoroughly cooked, such as soft-boiled eggs.
Offenders face a maximum fine of HK$50,000 and six months in prison (chilled or frozen meat and poultry also need an import license, with a maximum of HK$500,000 and two years). Compounded foods such as dumplings and wonton do not need a certificate
Cash, etc.
If you carry currency and bearer negotiable instruments (such as bearer checks) totaling more than HK$120,000, declare them to Customs at the Red Channel. An accompanying adult who knows that a young person under 16 is carrying them must declare for that young person.
A first-time breach may be settled by paying HK$2,000 under certain conditions; other cases face a maximum fine of HK$500,000 and two years in prison
Failing to declare, or making a false declaration of, alcohol or tobacco over the duty-free quantities can lead to prosecution. Rules can change, so check the latest information from the Hong Kong Government before you go.
