Imported products are all the rage among residents of China's first - and second-tier cities, such as Beijing, Shanghai and Hangzhou. With a few clicks of the mouse, world-class delicacies arrive at the dinner table, from Alaskan black cod and Canadian lobster to French wine and British tea.

The typical buyers of overseas goods are well-educated young women who earn over 100,000 yuan ($14,588) annually, Alibaba said. Buyer profiles by YHD and other retailers were similar.

The countryside hasn't been left out, either. More than 500 overseas premium brands are available in China's hinterlands via Rural Taobao, an arm of Alibaba that facilitates online shopping and home delivery through over 10,000 rural service centers in villages across China. 

Seasonal sales of other products also are picking up.

"People are reaching beyond traditional purchases of food and clothing, to look for something personalized and from overseas," said Kaola.com spokeswoman Wang Zheng.

Cosmetics and maternity products are popular, including lipstick, anti-aging masks and infant formula. Air purifiers and smart gadgets like virtual reality headsets also are up-and-coming products, retailers say.

Chinese online shoppers spent on average $473 on imported purchases in 2016, according to consultancy eMarketer. The company said cross-border e-commerce is expected to reach a quarter of the Chinese population by 2020.
