Q: I sent from France a package to Shanghai, but the package is held at the customs because the invoice is not with the package. I can send by email the invoice, but I don't have the "email address" to send it. What should I do?

A: You can complete the supplementary declaration through one of the following platforms:

1. Online submission through official customs platforms:

"Internet + Customs" platform ("互联网+海关”一体化平台):

"China Customs" (掌上海关) app

"China Customs" (掌上海关) WeChat mini program

China International Trade Single Window (中国国际贸易单一窗口):

"China International Trade Single Window" (掌上单一窗口) app

"China International Trade Single Window" (掌上单一窗口) WeChat mini program

These platforms provide a one-stop online mail service for handling declarations.

2. In-person submission at the customs service counter of the local post office to complete the supplementary declaration.

3. Online handling through the postal company's service platform.

Note: There is no service fee when using official online customs channels or visiting the customs counter in person.
