Why can't I buy anything when I travel to Sanya?

Because Sanya Duty Free Shop implements the tax exemption policy for outlying islands, it needs to leave the island to be tax-free. This is the international practice of tax exemption for outlying islands, and it is also the requirement of China's customs supervision.

National policies restrict the purchase of duty-free goods to leave the country or leave the island. Buy good things in Sanya Duty Free Shop, pick them up in the quarantine area after airport security check, and ensure that the duty-free goods you buy are taken out of the country or off the island.

Extended data:

Definition of duty-free policy for outlying islands: Duty-free policy for outlying islands refers to a preferential tax policy for passengers who fly out of the island (excluding departure) to purchase goods free of import duty for a limited number of times, a limited quantity and a limited variety, pay them in duty-free shops (that is, duty-free shops for outlying islands) and pick up goods from outlying islands in the airport isolation zone.

The premise for passengers to enjoy the tax-free policy on outlying islands is "outlying islands", and residents on the island also need to rely on air tickets on outlying islands to enjoy preferential policies. If the flight is delayed or cancelled, the duty-free goods will be kept by the duty-free shops (including the pick-up points) and will be picked up after the actual flight leaves the island and enters the quarantine area again. At present, passengers can only enjoy the preferential tax-free policy for outlying islands by air tickets, but consumers who leave the island by car, train, ship and other means of transportation cannot enjoy this preferential policy. As for whether the vehicle restrictions on outlying islands will be broken, the relevant departments will make adjustments according to the trial situation of the tax exemption policy on outlying islands.
