My package is currently held in Nanning Customs for over a week now. It is a returned goods (jewelry) to the seller and I shipped back to them using USPS. My seller has not received any mail or call from Customs. They called China Post for help, but China Post cannot help because customs is holding it. They call China Custom (12360) and China Custom say they do not have package for some reason when the tracking says it is held in customs. Is there tax on returned goods?
Can you help me so I can have the package delivered?

My package has been held in customs for 5 days now. Last two updates were , taxable mail, to be paid by the recipient and the import custom keeps pending. What does that mean? Should I worry?

Hello, my letter was delivered to 心巢御园后面洁丽干洗店自提点 on Jan 26, but because of Lunar New Year, the recipient had returned to her hometown. The staff of the store then brought the letter to 重庆九龙坡区心巢御园后面门店驿站 due to New Year too. According to the recipient who went to collect it, the staff at the 驿站 said that the registered number is not common so they do not know where to classify it in the system. Hence, the registered letter does not exist in the system now. The staff were not willing to make the effort to find it either. I paid for it to be registered, and it wasn't even registered into the system when it was brought to a different place!? What can be done for this situation and how do I get my letter delivered into the hands of the recipient? The recipient went to the 驿站 again today (March 9th) and told me that there was a change of staff. The letter is still not found!
