Duty-free shopping at SFO is available inside the International Terminal to passengers holding a boarding pass for a flight leaving the United States. Buy from these shops and you skip federal duty, federal excise taxes, and California sales tax. Bring your passport and your international boarding pass to the register, and be aware that a domestic connection before you leave the country, or an import allowance at your destination, can undo the savings.
Where the Shops Are
SFO’s duty-free stores sit inside the International Terminal, in Boarding Area A and Boarding Area G, past the security checkpoint. Only ticketed passengers can reach them. The stores are positioned near gates serving international departures to Asia, Europe, and Latin America.
DFS Group, owned by LVMH, has held the exclusive duty-free concession at SFO for years. That concession is transferring to Duty Free Americas in 2026, with the deal expected to close in the second quarter. The physical store locations stay the same through the transition.
What You Need at the Register
Duty-free shops are legally classified as Class 9 bonded warehouses under federal customs law.1eCFR. 19 CFR Part 19 – Customs Warehouses, Container Stations and Control of Merchandise Therein They can only sell to people who are exporting the goods by leaving the country, so the cashier needs two documents from you:
- A valid passport to establish your identity.
- An international boarding pass showing you are departing the customs territory on a specific flight. A domestic boarding pass will not work.
The retailer records your flight number and destination. Without both documents, the store either refuses the sale or charges you full price with all applicable taxes. There is no workaround.
What Taxes You Skip
Federal law defines duty-free merchandise as goods “on which neither Federal duty nor Federal tax has been assessed pending exportation from the customs territory.”2Office of the Law Revision Counsel. 19 USC 1555 – Bonded Warehouses Three layers of tax drop off your purchase:
- Federal excise taxes, which hit alcohol and tobacco hardest. Federal excise tax on distilled spirits runs roughly $2.14 per 750ml bottle at the standard rate, and cigarette excise adds over $1 per pack.
- Customs duties on imported goods, waived because the goods are classified as exports leaving with you.
- California sales tax. The combined rate in San Mateo County, where SFO sits, is 9.375% as of 2026, and duty-free purchases skip all of it.3California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rate Information
Combined savings on premium spirits can reach 20 to 30% compared with Bay Area retail. On cosmetics and fragrances the savings are real but smaller, since those products don’t carry excise taxes. Luxury accessories like handbags, watches, and sunglasses vary based more on the brand’s own pricing than on tax elimination.
How You Receive Your Purchases
Not everything is handed to you at the register. Federal regulations require duty-free merchandise to be delivered at or near the “exit point,” which for airports means the gate holding area or the jet bridge.4eCFR. 19 CFR 19.39 – Delivery for Exportation
At SFO, smaller items like cosmetics and accessories are typically bagged and handed to you in the store, since you are already past security. Liquids over 3.4 ounces and tobacco products are more likely to be sealed and delivered at the gate. You pay at the register, receive a claim ticket, and pick up the sealed bag as you board.
The Connecting-Flight Problem
This is where travelers most often lose their purchase. A full-size bottle of liquor from SFO’s duty-free will not clear a second TSA checkpoint on its own. The 3.4-ounce liquid rule applies at every TSA screening.
TSA allows larger duty-free liquids through security only when all of the following are true:
- The liquids were purchased at an international duty-free shop and you are on a connecting flight entering the United States.
- The retailer sealed them in a transparent, tamper-evident bag (a STEB) with no signs of tampering.
- The original receipt is present, and the purchase was made within the previous 48 hours.
The direction matters. This exception protects liquids bought abroad when you connect through a U.S. airport on the way home. It does not protect a bottle you buy at SFO if you have a domestic leg before leaving the country. Flying SFO to JFK and then JFK to London, for example, means re-clearing security at JFK, and a full-size bottle from SFO would be confiscated unless checked.5Transportation Security Administration. Liquids, Aerosols, and Gels Rule If your international flight leaves directly from SFO, this is not an issue.
What You Can Bring Home
Skipping U.S. taxes on the way out does not make the item tax-free when you arrive. Every country sets its own import allowances, and anything over the limit gets taxed at customs on the far end. Duty-free purchases also count against your personal exemption when you return to the United States.6U.S. Customs and Border Protection. Know Before You Go – Traveling Abroad
Personal Exemption
For U.S. residents returning from abroad, the personal exemption is $200, $800, or $1,600 depending on the countries visited.7U.S. Customs and Border Protection. Duty-Free Exemption The $800 tier covers most destinations. Anything above your exemption is subject to duty.
Alcohol
Under the standard $800 exemption you may bring in up to two liters duty-free, provided one liter was produced in a qualifying country. The $200 exemption allows just 150 milliliters. The $1,600 exemption from U.S. insular possessions permits up to five liters with specific sourcing requirements. Cruise ship duty-free purchases qualify for one liter.8U.S. Customs and Border Protection. Types of Exemptions State alcohol control boards can impose additional limits at your entry point.
Tobacco
The standard tobacco allowance from most countries is 200 cigarettes and 100 cigars.9U.S. Customs and Border Protection. Carrying Tobacco Products to the United States Exceeding those quantities triggers duties and possible seizure. Declare everything accurately on the customs form; undeclared goods carry penalties far steeper than the duty itself.
No California Sales Tax Refund for Regular Shopping
If you were hoping to reclaim California sales tax on things bought at regular stores around San Francisco, the way VAT refunds work in Europe, that program doesn’t exist here. The United States has no federal VAT, and California offers no sales tax refund mechanism for international visitors. Sales tax paid downtown is gone whether or not the item leaves the country. The duty-free shops at SFO are the only way to skip local taxes on airport purchases.
