Hainan island
 
Why in news?
Hainan, a tropical island province in southern China with Haikou as its capital, became a distinct customs supervision zone on December 18, 2025. It has been made a special customs zone so that  goods from other countries can enter Hainan easily with very few checks. Sending goods from Hainan to mainland China is more tightly controlled and if products are processed in Hainan and gain at least 30% extra value, they can go to mainland China without paying any duty.
