Kevin Tan from AAE Express Soho, also in Flushing, said a large number of their orders from the Chinese mainland are for milk powder.
But some medical experts have expressed concern, saying foreign milk powder may not be suited to the Chinese diet.
Zhang Silai, former head of pediatrics at Beijing Hospital of Integrated Traditional and Western Medicine, said there are many risks with imported milk powder, especially buying through traders who may send a product that has spent a long time in storage.
Zhang said milk powder produced and sold in foreign countries was developed to suit that marketplace, and may not be suitable for Chinese babies.
"I suggest parents buy brands sold in China because they have added some nutritional components suited to our eating habits and physical features," Zhang said.
"Milk powder sold in Japan has a lower portion of some omega-3 fatty acids because they eat a lot of seafood, but Chinese babies need it," she said.
Several large foreign companies that produce infant and toddler formula, including Nestle and Wyeth, have built factories in China to start production of milk powders for the domestic and foreign market.
Zhang said the increase in local production by multi-nationals could ease the demand for imported milk powder.
"Because Chinese parents can buy these brands in their local markets, the supplies for other countries will be increased," Zhang said.
The pediatrician said more should be done to encourage mothers to breast-feed.
"Companies should set up special rooms for working mothers to express their breast milk," Zhang said. "Breast milk is good for babies' health and will reduce the consumption of milk powder."
Wang Dingmian, former vice-chairman of the Guangdong Dairy Industry Association, said Chinese parents are highly dependant on milk powder and more should be done to encourage breast-feeding.
