Hi Joao,

If it's stuck there for a long time, it should be waiting for the receiver in China to declare to the customs now. You'd better contact the receiver in China to ask if he has received the notice from the customs. If no, let him check through authorized tax collection system (http://int.ems.com.cn/mailtax) to check or call China customs service number 12360 to check.

I'm the receiver and china customs didn't contact me cause the seller didn't add my phone number in the package. I called the customs and they said I need to contact with china post, china post said is not their business.
