禁止寄遞物品指導目錄（國郵發〔2016〕107 號）：19 類 188 種禁寄物品，集運高風險者：第 4 類壓縮和液化氣體（含打火機）、第 5 類易燃液體（含酒精成分香水、指甲油、油漆）、第 12 類毒品及易製毒化學品、第 16 類侵犯智慧財產權和假冒偽劣物品（盜版品、假藥）、第 17 類瀕危野生動植物及其製品（象牙、虎骨）。另《快遞暫行條例》（國務院令第 806 號，2025-06-01 施行）要求實名收寄、收寄驗視與安全檢查。（國家郵政局 / 公安部 / 國家安全部）

This column maps China's export control categories by the first 6 digits of the HS code and is for reference only. China's customs commodity codes have 10 digits, and from the 7th digit onward they do not correspond to Taiwan's tariff numbers. China also states officially that “the scope of goods is determined by the goods description; customs commodity codes are provided as a reference for customs declaration”, and for dual-use items that “a licence must be obtained as required by law whether or not a customs commodity code is listed”, so whether goods may be exported cannot be judged by the code alone. Some control measures are currently suspended; actual export rules are subject to China's latest official announcements.
