Most of this atlas looks at what China has already built. This one looks ahead. On 18 December 2025 China turned an entire tropical island into a single free trade port — its own customs, tax and regulatory system — in what officials call the boldest reform experiment since 1978. Whether it works is the open question of the next decade.
China has more than twenty free-trade zones, but they are urban districts or industrial parks that tweak the rules at the edges. Hainan is different in kind: as of 18 December 2025 the whole island — about 35,000 km² and ten million people — became one special customs territory, inside China's borders but outside its ordinary customs regime. The governing idea is a single sentence: free at the first line, controlled at the second, free flow within. The first line is the boundary with the rest of the world; the second is the strait between Hainan and the mainland.
The product Hainan is selling is not a thing but a set of rules. Goods arriving from overseas are now zero-tariff across roughly 6,600 categories — 74 percent of all tariff lines, up from 21 percent — covering nearly all production equipment and raw materials. A value-added processing rule lets a company import parts duty-free, add at least 30 percent of value on the island, and ship the finished product to the mainland tariff-free, sidestepping the usual trade walls. Companies in encouraged industries pay 15 percent corporate tax and high-end staff cap out at 15 percent personal tax, against 25 and up to 45 on the mainland. Fifty-nine nationalities enter visa-free.
The island is spreading its bets across a handful of nodes. Sanya and Haikou anchor tourism and the duty-free shopping that already pulls in mainland buyers. Yangpu in the northwest is the deep-water port and petrochemical base, the natural home for offshore processing under the value-added rule. Wenchang on the northeast coast is China's seaside rocket base and a commercial-space cluster. Boao Lecheng is a medical-tourism zone where drugs and devices not yet approved on the mainland can be used. And Yazhou Bay, by Sanya, pairs deep-sea research with the Nanfan winter seed-breeding base, China's crop-breeding 'Silicon Valley'. Around it all: tropical agriculture and offshore energy.
None of this is guaranteed, and Hainan has been here before. It was made a province and China's largest Special Economic Zone in 1988, then a property bubble burst in the 1990s and the island spent thirty years lagging the mainland coast. The free trade port is a policy bet with real execution risk: the whole model depends on the second line actually stopping duty-free goods from leaking to the mainland, on attracting companies that genuinely operate there rather than shell registrations, and on competing with entrenched Hong Kong and Singapore — all from a small population and a thin industrial base far from the big clusters.
What has changed is the weight behind it. The central backing is heavier than in 1988, the timeline is explicit — master plan in 2020, customs closure in 2025, a mature port targeted for 2035 and a globally influential one for 2050 — and the positioning is sharper: a tariff-free, low-tax gateway sitting between China and ASEAN, aimed squarely at the trade that now runs through Malacca and Singapore. Whether Hainan becomes a second Hong Kong or an expensive experiment is exactly the kind of question this atlas will be able to answer in a decade. For now it is the most interesting blank space on China's industrial map.
