Speciality milk producer Synlait Milk Limited has successfully re-registered A2 Milk's Chinese labelled infant formula.
Production will begin this month.
The approval from China's State Administration for Market Regulation allowed Synlait to manufacture A2 Milk's infant formula (IMF) at its Dunsandel facility for export to China until September 2027.
A2 Milk managing director David Bortolussi says IMF will be sold under its new China product label, which was a key part of its refreshed growth strategy.
"The approval provides (A2 Milk) with continued access to China's substantial registered domestic infant milk formula market which remains the key focus of our refreshed growth strategy."
Synlait chief executive Grant Watson said the re-registration was pivotal to the ongoing success of the manufacturing and supply agreement Synlait had with A2 Milk.
"Our shareholders, staff, customers, and farmer suppliers all benefit from the certainty of today's re-registration and continued China market access," Watson said.
