求翻译：很抱歉，因中国运输机构的安检系统升级，发出的货物在海关没有通过安检被退回，货代重新打包后已经再次发出，因此货物可能延迟到达是什么意思？

Sorry, due to China's transportation sector security system upgrade, the Department does not send the goods to be returned through the security check, after the freight has been re-packaged re-issue, it may delay the arrival of goods

正在翻译，请等待...
