4px is only available in Shengzhen city as far as I know. I used to use them to deliver goods to U.S. As I live in Qingdao City in northeastern China part, I use a China domestic express first to send it to Shenzhen to them and then they help me to deliver. You can call them through 86-755-23508000 or +61 (3) 9416 8777 to ask if they could help you send.
