Once a prefixed quota has reached, China has the right to trigger a "special agricultural safeguard". Under the safeguard, all subsequent imports of the particular product are subject to the ‘most favoured nation’ rate. Over the past decade, Australian dairy milk exports to mainland China have grown more than fourfold – rising from A$277 million in 2010 to A$1.1 billion in the past 12 months. Australian whole milk powder imports in China were subjected to the special agricultural safeguard. The special safeguard for whole milk powder may be triggered later this year if Australian whole milk powder exports exceed 22,335 tonnes.
