The proportion of tariff lines with zero-tariff products in Hainan Free Trade Port will increase from 21 percent to 74 percent, according to a press conference held on Wednesday.

Wang Changlin, deputy head of the National Development and Reform Commission, announced that the free trade port will launch island-wide independent customs operation on Dec. 18, 2025.

Vice Minister of Finance Liao Min noted that duty-free items in Hainan will increase from about 1,900 to around 6,600, marking a significant boost in openness.

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.

"We will take a targeted regulatory approach of low-intervention and high-efficiency for zero-tariff and relaxed management goods, ensuring smooth implementation of the opening-up policies," Wang said.
