Infant formula maker Bellamy's Australia said it had requested an extension of a share trading halt as it seeks more information about China's decision to suspend the import licence of its newly acquired Australian cannery.

After entering a trading halt on July 7 following the suspension, Bellamy's said in a statement on Tuesday the Chinese regulator in charge of its import licence had asked it for "certain information" about its Camperdown Powder factory.

The licence suspension was a result of allegations a third party had made to Chinese authorities about "certain previous quality issues" concerning Camperdown's processing facility, it added. A Bellamy's spokesman would not name the third party.

China accounts for a third of Bellamy's revenue and a third of its pre-tax profit, according to its half-yearly earnings update in February.

The regulator had not made any findings against Camperdown, Bellamy's said.

In any case, the licence suspension would not affect its China-bound formula since the factory currently made product only for third-party vendors.

Bellamy's stock last traded at $6.74 on Thursday, sharply down from a peak about $15.10 last August.

The company requested its shares be suspended until July 24.
