The visa guide takes you to the immigration desk and lists the customs and health declaration as one item among the things you need. That is where it stops, and it is also where almost every English account of Chinese customs stops — except that most of them go on to describe procedures that no longer exist.
The words red channel, green channel and declaration form appear nowhere else on this site. They are the whole of the two minutes after you pick your bag off the belt, and the rule behind them was rewritten last year.
One order replaced six, on 1 April 2025#
The 中华人民共和国海关进出境行李物品监管办法 (Zhōnghuá Rénmín Gònghéguó hǎiguān jìnchūjìng xínglǐ wùpǐn jiānguǎn bànfǎ, Measures of the Customs of the People's Republic of China for the Supervision of Inward and Outward Baggage and Articles) were adopted at the executive meeting of the General Administration of Customs on 23 December 2024, published as Order No. 276 on 17 February 2025, and have been in force since 1 April 2025.
Article 38 clears the ground behind it. Six instruments were repealed on the day it took effect:
| Repealed | What it had governed |
|---|---|
| Customs Order No. 9 of 1989 | Passenger baggage supervision |
| Customs Order No. 25 of 1991 | Transit passengers' baggage |
| Customs Order No. 35 of 1992 | Travellers' articles for personal use |
| Customs Order No. 55 of 1995 | Passenger clearance |
| Customs Order No. 58 of 1996 | Baggage of Chinese-national travellers |
| AQSIQ Order No. 146 of 2012 | Quarantine of items carried by travellers |
Two things are worth reading out of that table. The first is the dates: guidance written from the 1989 and 1996 orders was describing a framework more than thirty years old, and a good deal of what circulates in English still does.
The second is the last row. Quarantine of what a traveller carries — the plants, the meat, the seeds — used to sit in a separate instrument issued by a separate body, the former quality-inspection administration, absorbed into customs in 2018. It is now inside the same order as everything else. The customs declaration and the quarantine declaration are one document under one rule, which is why the form asks about fruit and sausages in the same breath as cash.
The channel rule has a second half#
The famous half is the one everyone knows: if you have something to declare, take the red channel; if you have nothing, take the green one. Article 12 has a clause after that, and it is the useful one:
That is a genuinely unusual drafting choice, and it inverts the instinct most travellers arrive with. The red channel is not an admission. It is the default the rule assigns to anyone who is not sure, and walking through it with nothing to declare costs you a conversation.
What "declare in writing" covers, and the two lists are not the same#
Article 9 sets out ten situations on the way in. Article 10 sets out seven on the way out. Putting them side by side is the fastest way to see what China is actually watching for in each direction:
| Situation | Entering | Leaving |
|---|---|---|
| Prohibited items | Yes | Yes |
| Restricted items over the limit, or needing a permit | Yes | Yes |
| Human tissue, blood, pathogens, biological products | Yes | Yes |
| Items contaminated by or risking a quarantinable disease | Yes | Yes |
| Currency in cash above the prescribed amount | Yes | Yes |
| Goods, samples, advertising matter | Yes | Yes |
| Animals, plants, their products and other quarantine material | Yes | — |
| Items above the duty-free allowance or quantity limit | Yes | — |
| Baggage arriving separately from you | Yes | — |
| Anything else the law requires to be declared in writing | Yes | Yes |
The three entry-only rows are the shape of the whole system. Plants, animals and quarantine material are an import question; the duty-free allowance is an arrival concept; and separately shipped baggage is something you declare when it lands, not when you go. What runs in both directions is the short list of things whose danger does not depend on which way they are travelling — contraband, permits, pathogens, cash and commercial cargo.
Cash is the row this site has already written about. The two separate ceilings — ¥20,000 in renminbi and the equivalent of US$5,000 in foreign notes are the "prescribed amount" that row refers to, and Article 9(6) and Article 10(6) are where the obligation to put them on a form actually lives.
The deadline is the moment an officer looks at your bag#
This is the provision no published guidance mentions, and it is the one with teeth. Article 11 says how a written declaration is made — a paper form or electronic declaration data, presented at the declaration counter with your travel document and any permits — and then ends like this:
That single sentence is the reason the red channel is worth taking on a doubt. The cost of walking through red unnecessarily is a question and thirty seconds. The cost of walking through green with something declarable is a deeming provision that does not care what you were about to say.
"Reasonable personal use" is the principle under all of it#
Article 5 is three lines long and governs everything above:
进出境行李物品应当符合合理自用的要求；超过合理自用数量的，按照货物办理海关手续。
Inward and outward baggage must meet the requirement of 合理自用 (hélǐ zìyòng, reasonable personal use); beyond a reasonable personal-use quantity, it is handled as cargo.
That is not a fine and not a confiscation. It is a reclassification: your six identical handbags stop being luggage and become an import, with the customs formalities an import carries.
This site has met the same four characters once before, in a completely different instrument. The State Council's drug regulations govern how much medicine you may carry in with the phrase 合理自用数量 (hélǐ zìyòng shùliàng), a reasonable personal-use quantity, in exactly these words. Same test, two different regulators — and the narcotics regulation quoted on that page goes further, putting controlled medicines through the border on the principle of personal use and reasonableness, applied by customs. Which is a good sign that arguing about the test at a counter is unlikely to go anywhere.
It is also the mechanism behind a warning the packing list gives without explaining: quantities of one product large enough to look commercial attract attention on the way out. The test is not a published number of kilograms. It is whether the quantity is reasonable for you to use.
In practice#
- Fill the declaration in before you land. It is done online or through a QR code at the airport, and doing it in the queue for immigration is doing it twice — the visa guide's arrival checklist lists it among the things you need at the desk.
- Take red on a doubt, not on a guilty conscience. Article 12 assigns the red channel to uncertainty by name. It is the compliant choice, not the suspicious one.
- Declare before anyone looks. Article 11's deeming provision closes the window the instant an inspection starts.
- Food, seeds and plants are the entry-only trap. They are on the arrival list and not the departure one, which is why travellers who have left China with a bag of dried mushrooms are surprised on the way back.
- Quantity is the question, not the item. Something perfectly legal becomes a cargo declaration at a large enough number, under Article 5.
- Buying to take home is a separate set of rules. Antiques, wildlife products and the export side generally sit under their own instruments, and Article 10's prohibited and restricted rows are only the door they come through.
- Hong Kong and Macau are separate customs territories. Arriving in either from the mainland, or the other way, is a border crossing with its own declaration rules — Order No. 276 does not govern it.
Frequently asked questions#
Do I have to fill in a customs declaration when arriving in China?#
You must declare in writing if any of the ten situations in Article 9 applies to what you are carrying — prohibited or restricted items, plants and animal products, cash above the limit, goods over the duty-free allowance, separately shipped baggage and so on. Many ports collect the customs and health declaration electronically before you reach the hall.
Which channel should I take at Chinese customs?#
Red if you have something to declare in writing, and red also if you do not understand the rules or cannot work out which channel to choose — Article 12 of Customs Order No. 276 says so in terms. The green channel is available to everyone else, but it is a permission rather than a default.
What are the current Chinese customs baggage rules?#
The Measures for the Supervision of Inward and Outward Baggage and Articles, General Administration of Customs Order No. 276, published on 17 February 2025 and in force since 1 April 2025. They repealed six earlier instruments, some dating from 1989, which is why a great deal of English-language guidance describes procedures that no longer apply.
Can I declare something after customs has stopped me?#
No. Article 11 provides that where a declarable situation exists and the written declaration has not been completed before customs takes an inspection measure, the traveller is deemed not to have declared. Declaring is something done at the counter beforehand, not offered once a bag is being checked.
What does "reasonable personal use" mean at Chinese customs?#
Article 5 requires baggage to meet a reasonable personal-use requirement, and provides that anything beyond a reasonable personal-use quantity is handled under cargo formalities instead. There is no published weight or count — it is a judgement about whether the quantity fits one traveller's own use, and the same principle governs medicines and goods bought to take home.
Is the quarantine declaration separate from the customs declaration in China?#
Not any more. The 2012 quarantine measures for items carried by travellers were repealed by Order No. 276 and their subject folded into it, so plants, animal products and quarantine material are declared under the same rule and on the same form as everything else.
