The design of the "Hainan Free Trade Port" commemorative postage stamp was revealed at a press conference on Monday.

This issue features a singular stamp illustrating key symbols representing the Hainan Free Trade Port, including the Wuzhishan Mountain, rice ears, rockets, a full-ocean-depth Human Occupied Vehicle known as Shenhai Yongshi (Deep Sea Warrior), and submarine optical cables.

The issuance is scheduled for Dec 18, coinciding with the launch of the island-wide special customs operation within the Hainan Free Trade Port.

After implementation, the proportion of tariff lines with zero-tariff products in the Hainan Free Trade Port will increase from 21 percent to 74 percent, and imported products that undergo at least 30 percent value-added processing in Hainan can enter the mainland tariff-free.

Certain goods currently banned or restricted nationwide will enjoy open policies in Hainan.
