As the average gross margin for China-based white-box tablet vendors/makers dropped below 5% in 2014, at least 30% of them have withdrawn from the market and shifted production to mobile power supplies, driving recorders and mobile device accessories, according to China-based National Business Daily (NBD).

White-box tablet production is concentrated in Shenzhen, southern China, and retail prices for such tablets mostly range from CNY299 (US$48.4) to CNY399, NBD said.

Of China-based white-box tablet vendors/makers which have not quit the market, some have started making business-use models, NBD indicated. For example, Cube has launched a Windows 8.1/Android 4.4 dual-OS business-use tablet for sale at CNY3,599.
