CHINA SHOPPING GUIDE

What tourists should not buy in China before flying home

A practical no-buy list for foreign visitors shopping in China before a flight: batteries, liquids, drones, food, replicas, medicine, customs risks and luggage trouble.

The main rule

Do not judge a China purchase only by price. Judge it by whether you can legally pack it today, clear airline checks, clear destination customs, and still use warranty or after-sales support after returning home. If any one of those steps is unclear, the saving is rarely worth the friction.

Tourist shopping in China is excellent on price for sealed tea, packaged snacks, small cultural gifts, stationery, lightweight fashion accessories and most non-counterfeit consumer electronics from official stores. The category where travellers lose money is not the cheap things; it is the cheap things that turn out to be undeclared, unprintable on a receipt, or unwarrantable at home.

What actually creates problems at the airport

Most airport trouble falls into a small number of categories: battery rules, liquid limits, knife and blade rules, destination quarantine on food and plants, and customs seizures on counterfeit or protected-species items. Working through this list before you pay is faster than doing it again at the gate.

If an item needs explanation at security, customs, or after-sales support, buy it only when the saving is large enough to justify that friction. The same rule applies to electronics with no factory reset, items without a working invoice, or items where the brand warranty will not recognise a foreign passport at home.

Eight categories that almost always cause trouble

These are the categories that come up most often in traveller reports. None of them is a hard "never" rule, but each one deserves a closer look before checkout, especially at airport duty-free where returns and refunds are difficult.

Large or high-capacity lithium batteries and power banks

Anything above 100 Wh needs explicit airline approval and must go in carry-on, not checked luggage. Anything above 160 Wh is not allowed in passenger baggage at all, regardless of airline.

Spare lithium batteries and loose power banks

Loose cells and standalone power banks must travel in your cabin bag with the terminals taped or covered, never in a checked suitcase. The cabin rule is universal for IATA member airlines and reflects fire-containment logic: a battery that catches fire in the cabin can be handled, in the cargo hold it cannot.

Liquids, gels and aerosols over 100 ml in cabin baggage

The 100 ml per container rule is the international standard. Anything larger than 100 ml in cabin baggage will be confiscated at security. The same items are usually fine in checked luggage if sealed, but glass bottles, perfume and alcohol over the limit create packing and leak risk.

Replica designer goods, counterfeit electronics and pirated media

Counterfeit goods can be seized at your destination's customs even when the purchase seemed normal in a Chinese market, and in some jurisdictions the buyer rather than the seller is liable. Markets that openly sell replicas are usually well known to customs in the countries those travellers come from, so buying there in the hope of avoiding attention is not a realistic strategy.

Ivory, reptile skin, traditional medicine containing protected species, and antique-looking crafts

Many souvenirs sold in China as antiques or traditional medicine contain or are made from protected species (ivory, pangolin scales, certain sea-horse products). CITES rules apply at the destination country's border, not China's, and seizures are common at US, EU and Australian airports.

Fresh food, raw meat, dairy, seeds and unpackaged herbal products

Destination quarantine rules are stricter than China's own. Many countries require travellers to declare food, plant material and animal products, and undeclared items are the single most common reason for a customs fine at arrival. Australia, New Zealand and the United States apply some of the strictest biosecurity rules in the world. Packaged, sealed, factory-labelled snacks are usually the safe answer.

Restricted, prescription and counterfeit medicine

Many countries restrict quantities of prescription medicine that can be brought across the border (typically a 30- to 90-day personal supply with the original prescription and the original packaging). Counterfeit medicine is sold openly in some markets; if a price looks too good to be true, it usually is.

Drones above local weight thresholds without registration

China requires real-name registration for drones above certain weights, and many countries (US Part 107, EU, Japan) require registration or a permit to operate a drone you are bringing in. A drone bought legally in China can still be illegal to operate, or even import, in the destination country without the correct paperwork.

Carry-on versus checked: a quick rule of thumb

The default rule is that cabin baggage gets you the more permissive rules for items you want to keep safe, but the more restrictive rules for items that are dangerous if they fail. Anything with a lithium battery belongs in the cabin. Anything liquid, glass, or sharp enough to wound belongs in the hold, in a sealed bag.

Item	Cabin baggage	Checked baggage
Power banks (any size)	Yes	No
Spare lithium batteries	Yes	No
Laptop, phone, camera	Yes	Yes
Drone aircraft and drone batteries	Yes	No for batteries
Liquids, gels, aerosols over 100 ml	No (over 100 ml)	Yes, sealed
Liquids up to 100 ml in a 1 L bag	Yes	Yes
Alcohol up to 70% ABV	Up to 100 ml	Yes, up to airline limit
Alcohol above 70% ABV	No	Varies by airline and country
Sharp objects (kitchen knives, scissors)	Blunt only	Yes, sheathed
Sealed packaged food and tea	Yes	Yes
Cigarettes and tobacco	Pocket use only	Up to duty-free allowance

Country and airline variations apply. Where this guide says "varies", check your airline's own dangerous-goods page and your destination's customs page before you fly.

Last-minute airport purchases to skip

Airport purchases deserve extra scrutiny, because the time pressure makes it harder to ask the right questions, and because exchanges and refunds at airport shops are usually harder than city shops. The items below are the ones that most often end up confiscated, broken, or regretted.

Cheap no-marking power banks

Without a clear Wh rating the battery cannot be screened, and most airlines will confiscate it at the gate. A 20,000 mAh unit at 3.7 V is about 74 Wh and a 27,000 mAh unit is about 100 Wh, but only if the rating is printed on the casing.

Last-minute liquor bottles over 100 ml

If you buy them in the duty-free shop after security, the store bags them in sealed tamper-evident pouches and most countries treat that as cabin-legal, but if you bring your own bottle from a city market the same exemption usually does not apply.

Souvenir knives, daggers or replica swords

Confiscated at cabin security regardless of how old or ceremonial they look. Pack them in checked luggage with the blades sheathed.

Market perfumes and large cosmetic bottles

A 200 ml bottle bought in the city cannot go in cabin baggage. Checked luggage can leak, especially in summer cabin temperatures, and the value is rarely worth the packing risk.

Loose tea or unpackaged herbs

Destination quarantine can seize them. Factory-sealed, labelled tea bags are fine; loose herbs in unmarked bags are not.

Usually safer alternatives

The bulk of China traveller purchases are safe, easy to lift, and travel well. Sealed packaged tea, snacks in intact factory packaging, small cultural gifts made from bamboo, wood or fabric, stationery, light accessories, scarves, silk items with a clear country-of-origin label, books, and any item where the brand warranty will be honoured at home.

For electronics, the safe rule is to buy from the brand's own flagship store or an authorised reseller, keep the printed invoice, and confirm at checkout that the model sold in the China market will work with the charger, voltage and network bands you have at home. Items with a clearly printed serial number and a 12-month brand warranty are the ones that hold their value after the trip.

Before checkout: a six-point check

Use this as a 30-second mental checklist at the till, especially in markets where haggling and gift-shop pressure make it harder to slow down. The questions are written in priority order; the higher up the list, the more often it is the real reason a difference does or does not work out.

Battery capacity and airline tier (100 Wh / 160 Wh)
Liquid volume for cabin baggage
Carry-on versus checked placement
Printed invoice with serial number
Destination customs status (counterfeit, CITES, food)
Warranty coverage in the home country

If any answer is unclear, take a photo of the product and the packaging, and decide later. The number of items that improve with a 10-minute pause is much larger than the number of items that improve with a 10-minute rush.

Authoritative sources for the rules above

Airline and country rules do change, and the safest place to check before you fly is the source itself. The two most useful baseline sources are IATA's lithium battery guidance (the standard IATA member airlines follow) and the U.S. FAA PackSafe page on lithium batteries (a plain-English summary of the same rules with screening scenarios). For destination customs, the destination country's own customs or biosecurity page is the only source that matters at the moment you fly.

Sources: FAA lithium battery PackSafe and IATA lithium battery guidance.

FAQ

Can I bring China snacks home?

Packaged snacks in factory-sealed packaging are usually easier than fresh food, meat, seeds, plants, or unpackaged herbal items, but destination rules still matter and a few countries prohibit even packaged meat and dairy.

Can I bring power banks from China?

Often yes, but power banks usually belong in carry-on luggage and must show rated capacity clearly. Anything above 100 Wh needs airline approval, and anything above 160 Wh is not allowed in passenger baggage at all.

Are replicas safe to buy?

No. Counterfeit goods can create customs and legal risk even if the purchase seemed normal locally, and in some jurisdictions the buyer rather than the seller is liable.

What about duty-free alcohol?

Liquor bought in airport duty-free after the security checkpoint is usually exempt from the 100 ml cabin rule when sealed in a tamper-evident bag, but customs allowances at arrival still apply and oversized bottles bought outside the airport are not exempt.

Can I bring traditional Chinese medicine?

Most packaged, factory-labelled medicine is fine, but liquids over the cabin limit, controlled-substance prescriptions, and any product containing protected-species ingredients should be checked against your home country's customs rules before you pack them.
