Following a recent change in international sector regulations, specifically Articles 18 and 19 of the Universal Postal Convention, starting from January 1, 2026, it will no longer be possible to send items (goods with or without commercial value) using International Registered and International Insured services, which will continue to be used exclusively for sending documents.
- 鉴于最近对国际部门法规的变更，特别是《万国邮政公约》第18条和第19条，自2026年1月1日起，将不再允许通过国际挂号和国际投保服务寄送物品（无论是否具有商业价值），这些服务将仅用于寄送文件。
