The South China Morning Post is reporting that the Chinese authorities are charging people a 20% duty if you bring your Idevice into China.

Mainland takes a 20pc bite out of travellers' Apples

Unfortunately the SCMP operates behind a paywall.  Here are some excerpts from the article:

"Customs officials across the border have been ordered to step up a crackdown on the smuggling of Apple devices, and people carrying iPhones or iPads are being slapped with an import duty even if they can prove they are for personal use."

"A Shenzhen customs official, who refused to be named, confirmed yesterday that bringing just one iPhone or iPad into the mainland would incur tax. "It's a common misconception that you can get a tax exemption if the device you are carrying is for self-use," she said. "In fact, iPhones and iPads are among the 20 products that are excluded from tax exemption. You need to make a declaration and pay the tax even if you are bringing in only one [device].""

"Most people are not aware of the latest crackdown and many said they had no problem crossing the border with an iPhone in their hands. An iPhone user from Indonesia said yesterday he did not know of the duty."
