Recently, the topic of Hainan's closure has exploded, with jokes like "BMWs worth 350,000 and Porsches worth 600,000" flying everywhere. Many people are eager to take advantage of the opportunity, only to find out—these half-price luxury cars are not sold to individuals at all; only enterprises can enjoy the policy benefits.

But this is just the surface. The real story is behind the scenes.

On December 18th, the full island closure operation in Hainan was launched, an important measure by the state to promote high-level opening-up. Many people are confused by the term "closure," thinking it means locking down the island. That's wrong. The logic of the closure is "opening on the first line, controlling on the second line, and free movement within the island"—more openness to the international market, and more precise management of transactions within the mainland.

The key change lies in taxation. After the closure, the scope of zero-tariff goods will expand directly from the current 1,900 tariff items to 6,600, with coverage jumping from 21% to 74%. This is not a minor adjustment; it significantly lowers the threshold for imported goods entering Hainan.

The vast majority of imported goods can now be duty-free upon landing. This has a profound impact on the entire import trade structure. But why can't ordinary consumers benefit from this? Ultimately, it is due to the original policy design—preferential policies are meant to attract industries and enterprises to settle in, not to create arbitrage opportunities for consumers.
