CY286176308DE is waiting for customs clearance by the recipient at Nanjing Customs.

Did the sender forget to write the recipient's mobile number on the packages? China Post needs to send a verification SMS to the recipient for them to use the app to declare customs. If the recipient hasn't received the SMS, please have the recipient call the local customs broker in Nanjing at 025-85420171 for assistance.

Another possibility is that the recipient simply does not want the package. This situation is usually due to the packages being shopping returns. Many unscrupulous sellers refuse to accept returns to avoid refunds. If this is the case, the postal company won't be able to help you. You need to contact your shopping platform (Amazon, AliExpress, PayPal, etc.) to file a complaint against the seller.

I hope the above information is helpful to you.

China Post database shows receiver hasn't made any customs declaration. Are you receiver? If yes, please call local phone number 025-85420171 and inquiry what is wrong with your customs clearance procedure.
