3-Way Checkpoint Guide: Customs (GACC) vs Flight Security (CAAC) vs High-Speed Rail
Green Channel permitted for reasonable personal travel supply (1-2 retail boxes, up to 30-90 days). Ensure the product is pure Diphenhydramine and does not contain Pseudoephedrine or Codeine.
Tablets and capsules allowed in cabin and checked bags.
China High-Speed Rail (CRH/G-Trains) security scanners focus on knives, aerosols (>150ml), and power banks (>100Wh). Personal prescription pill bottles, EpiPens, and insulin cooling pouches pass through railway security without restriction.
Travelers frequently confuse China's three security agencies: 1) GACC Airport Customs checks drug ingredient legality upon international arrival; 2) CAAC Domestic Flight Security strictly enforces rules on gel ice packs (>100ml) and hypodermic needles (requiring a hospital letter); 3) China High-Speed Train Security does NOT scrutinize personal pill boxes or medical ice packs.
