Brunei gives American passport holders one of the easiest entries in Asia, a 90-day waiver with no application. It also has customs rules that catch more visitors than any other country in the region, because they are unlike anything a traveler from the United States has encountered.
None of this was obscure. The Royal Customs and Excise Department published all of it, on a page almost nobody read before flying.
The department republished it, and this page ran on an archived copy for four days. The old single-window site at bdnsw.mofe.gov.bn still returns 404 on every path, and on 14 September we recorded that customs.gov.bn carried no replacement. It does. Passenger Concession is live at customs.gov.bn, it is fuller than the version that disappeared, and every figure below was rechecked against it on 18 September 2026. On 24 September we re-read it again and brought the quotations into line with its current wording, which is shorter than the text this page first quoted. No figure moved, and the old mention of a special liquor form is gone because the current page does not describe one.
One figure changed in the reader’s disfavour, and it is the alcohol one. The archived page listed two bottles of liquor and twelve cans of beer as two unpunctuated lines, which this page read as both. The current page writes it as a choice.
There is no tobacco allowance. None.
Start here, because this is the one that costs people money at the counter.
The department’s page puts it in one sentence: “There is no personal concession granted for importing cigarettes into Brunei Darussalam.” The next sentence sets the price:
Any person importing cigarettes into this country must declare such goods and it is subject to an excise duty of BND0.50 per stick.
Fifty Brunei cents per cigarette. Not per pack. A single carton of 200 cigarettes is B$100 in duty, and it is not optional or negotiable. The obligation is to declare, and the duty follows.
If you smoke, the practical answer is to arrive without tobacco.
Alcohol is permitted, but only for some passengers
Brunei is a Muslim country and does not sell alcohol. It does allow visitors to bring a limited quantity in, and the first condition on the list is who may do it: the importer “Must be non-Muslim aged 17 years and above”.
The quantity is a choice between two options rather than a sum of them:
Each person can only bring in 2 bottles of liqueurs (1 litre per bottle) or beer not exceeding 12 cans (330ml per can)
So it is two litres of spirits or wine, or just under four litres of beer, and taking some of each is not what the concession grants. That one word decides whether a bag holding a bottle and a six-pack is inside the concession or a declaration, and the archived page it replaced set the two options out as separate lines with no conjunction at all.
The conditions on alcohol, which are the part people miss
You must declare it. The condition reads “Every importer must declare to the proper officer of customs”. This is a positive obligation, not a green-channel judgement call.
You must wait 48 hours between importations. The rule is that “The subsequent importation must be 48 hours from the last importation.” If you cross from Malaysia twice in a weekend, the second crossing is not another allowance.
It is for you, and for where you are staying. The source is unusually specific:
The alcoholic liquor shall for the importer’s personal use and not to be given, transferred or sold to other people; The alcoholic liquor shall only be stored and consumed at the importer’s private residence.
So the allowance does not make alcohol portable within Brunei. Buying a bottle for a Bruneian friend is outside the rule as written, and so is drinking it somewhere other than where you are staying.
Everything else
The general passenger concession covers personal items of your own for passengers aged 17 and above, under the Second Schedule, Part B, No. 9 of the Customs Import Duties Order 2007, with the published detail that the goods are personally used rather than new. Named limits are perfume not exceeding 60 millilitres and eau de toilette or scented water not exceeding 250 millilitres.
Three thresholds low enough to catch an ordinary suitcase
All three are on the current page and none were on the archived one.
Processed food: no more than 3 pieces of each item, a total weight under 5kg across the whole import, and a total declared value under B$100.
Cosmetics, medicine and health supplements: the Ministry of Health sets a threshold of B$200 for every declaration, for personal consumption.
Plants and plant products: not more than 6kg each of fruit, vegetables, spices, legumes, cereals, tubers, rhizomes or plant products such as banana leaf, plus one flower bouquet and no more than six flasks of tissue culture.
The penalty is named, and the general value cap still is not
The department does publish what happens when a declaration is wrong. Failure to give a true and correct declaration is an offence “punishable under Section 138 of Customs Order, 2006 and Section 144 of Excise Order, 2006”. It states the sections rather than the fines, so the amount is still something to ask about rather than assume.
What the page does not give is a general value threshold for goods outside the categories above. That figure is not one we will estimate.
If you are arriving with something valuable, or with more than the quantities above, the useful move is to declare it and ask. Brunei’s rules are strict and clearly published, which makes them easy to comply with and awkward to argue with afterwards.
Brunei charges duty on every cigarette, with no relief whatsoever, and that puts it at one end of a range worth seeing whole: the range runs from Brunei’s nothing to the 200 cigarettes that Japan, Thailand and Vietnam each allow, every figure stated in the units its own customs service chose.
