A ¥100,000 per-person annual quota that both Chinese and foreign travellers leaving Hainan can use — cosmetics, perfume, watches and bags 20–35% cheaper, all under one 72,000 sqm roof.
Picture this: you walk into a mall wider than ten football pitches, ceilings soaring, the air-con a relief from Haitang's heat, and all around you are Cartier, Bulgari, Tiffany, Gucci, Prada and Loewe counters lined up in long rows — except the prices on the tags sit below what you'd see in Bangkok or Hong Kong. That's because these are offshore duty-free prices, a perk that exists only on Hainan island.
This is the CDF Haitang Bay Duty-Free Mall (海棠湾免税城) — the duty-free complex at Haitang Bay, opened in 2014, with around 72,000 sqm of retail floor (about 120,000 sqm across the whole development) and more than 650 brands. It's the largest single duty-free store in the world, run by China Duty Free Group (CDFG). Beyond the Haitang Bay flagship, downtown Sanya has a second CDF Mall you can shop at too.
What sets it apart from an ordinary airport duty-free is the ¥100,000 per-person annual quota — buy as many times as you like until you hit it — and the fact that both Chinese citizens and foreign travellers (Thai visitors included) leaving Hainan can use the same allowance. That's why so many people now plan a Sanya beach trip and a shopping run in one go.
The rules that bring the prices down — and the limits a lot of people don't learn until they reach the counter.
Both mainland Chinese and foreign travellers (Thai visitors included) who are about to leave Hainan island by air, train or ship can use the offshore duty-free allowance. Foreign travellers present their passport along with proof of an onward flight or train. Hainan residents have their own rules — for example, from 2026 they can buy without leaving the island, but cannot buy electronics, phones or cameras duty-free.
The current allowance is ¥100,000 (about ฿500,000) per person per year. You can buy as many times as you like, but the year's total must stay under the cap, and any unused balance is lost — it does not carry to the next year. Each family member, children included, has their own quota, so a family of four can buy up to ¥400,000 between them.
On top of the money cap, a few categories have a per-trip unit limit: phones/tablets are capped at 4 units, alcohol at 1.5 litres combined, cigarettes at 2 cartons (400 sticks). Cosmetics, watches and bags have no unit limit — only the overall money quota. These numbers shift with policy, so check the current terms before you shop.
For tourists, most purchases are delivered to a pickup counter at the airport (or train station) after you clear security on your departure day — aim to get there 2–6 hours before your flight. Since 2023 there's also a "buy now, pick up now" option for around 15 categories such as cosmetics, perfume, shoes, clothing and baby formula, which you can carry straight out — but it excludes watches, jewellery and liquor, which still go to the airport.
Inside the mall, Alipay and WeChat Pay are the main options (you can now link a foreign card to either app), and some counters take international Visa/Mastercard. Set up a Chinese payment app before you travel — see our guide to paying in China with Alipay/WeChat.
Cosmetics (around 30–35% cheaper) are the star here — counter brands like La Mer, Estée Lauder, SK-II and Lancôme are all well stocked and usually beat the counter price back home. Then come perfume (~28–33%), designer bags (~25–30%) and watches (~20–28%). The real gap depends on the brand, the model and the exchange rate at the time.
The smart-shopper move: note the home price of whatever you want first, then photograph the mall tags to compare. Things that are already cheap or frequently discounted at home may not differ much — but luxury goods, large perfume bottles and cosmetics sets tend to be clearly worth it.
The best-value category and the main reason people come. Both luxury and counter brands, and it qualifies for "buy now, pick up now" — so you carry it straight out of the store rather than collecting it at the airport.
Big-name fragrances at good prices, especially large bottles and gift sets. It's another carry-out-now category.
Many designer brands under one roof at prices that beat a lot of cities. Stock and available models vary by season, and the popular pieces go fast.
Cartier, Bulgari, Tiffany, Piaget and more — the saving is meaningful on pricier pieces, but this category doesn't qualify for instant carry-out, so you collect it at the airport counter on departure day.
The mall is at No. 118 Haitang North Road, Haitang District — in the northeast of Sanya, beside the luxury-resort cluster of Haitang Bay. The easiest and cheapest way to get there is the free shuttle.
Stay in Haitang Bay and you're in the same district as the CDF mall — shop, then walk back to your room.
