Quick Answer
China’s customs and aviation rules are strict but clear.
Most travelers run into trouble not because they bring illegal items, but because they assume international norms apply.
If an item is restricted, do not try to explain—do not bring it.
The Core Reality (Why People Get Stopped)
Most problems happen because:
- Items are legal elsewhere but restricted in China
- Travelers are unaware of local aviation rules
- Assumptions are made based on other countries
China enforces local standards, not global averages.
Items You Should NOT Bring
You should avoid bringing:
- Illegal drugs or substances
- Weapons or weapon-like items
- Certain medications with restricted ingredients
- Counterfeit goods in quantity
- Politically sensitive materials
These are enforced consistently.
High-Risk Everyday Items (Often Overlooked)
Power Banks (Very Important)
Power banks used on domestic flights in China must:
- Have a visible China 3C certification mark
- Clearly show rated capacity
- Be within allowed capacity limits
If your power bank:
- Has no 3C logo
- Has unclear labeling
- Is an overseas-only brand
👉 It may be confiscated at airport security, even if it is allowed in your home country.
This surprises many travelers.
Knives and Multi-tools
- Pocket knives
- Multi-tools
- Scissors
Often confiscated at security checkpoints.
Drones
- Drones themselves may pass customs
- Flying them is heavily restricted
- Confiscation is possible if rules are violated
(See drone guide for details.)
Medicines (Quick Reminder)
Problems occur when:
- Quantities are excessive
- Packaging is removed
- Restricted ingredients are present
Bring reasonable amounts only.
What You Can Bring (Normally Safe)
Generally safe:
- Personal electronics
- Clothing and personal items
- One phone, one laptop, accessories
- Small personal-use quantities
Customs focus on intent and scale.
Aviation-Specific Rules (Often Confused)
For flights within China:
- Power banks must be carried in cabin
- Must meet Chinese aviation standards
- Staff will physically inspect items
International allowances do not override local enforcement.
Exact Actions: Avoid Problems
Step 1: Inspect your power bank
- Look for 3C logo
- Check capacity labeling
- If unsure, leave it behind
Step 2: Remove questionable items
- Tools
- Sharp objects
- Large batteries
- Drones (if not essential)
Step 3: Do not argue at security
- Confiscation decisions are final
- Explaining foreign rules does not help
- Compliance keeps things smooth
Common Mistakes Travelers Make
- Assuming “it was fine last country”
- Bringing multiple power banks
- Carrying unlabeled batteries
- Packing tools “just in case”
- Trying to negotiate at security
These slow you down and often fail.
Reality Check
- Enforcement varies slightly by airport
- Security staff follow written rules
- Items are confiscated, not returned
- Preparation is the only defense
This is procedural, not personal.
What Locals Do Instead
- Use locally purchased power banks
- Avoid carrying tools
- Travel light through security
- Accept confiscation without argument
You should follow the same approach.
Checklist
- Power bank has visible 3C certification.
- Capacity clearly labeled.
- No sharp tools in carry-on.
- Medicines packed reasonably.
- Drones reconsidered.
