Singapore is a country that is very strict when it comes to its duty-free concessions and it takes it very seriously. When it comes to alcohol, it is limited based on what you're going to purchase. You can look to buy one litre each of any spirits, beer and wine, Or you can buy 2 litres of wine and then one-litre of-of beer, either way, you cannot exceed one litre of spirits when purchasing alcohol. Another point to note is that there is no duty-free allowance on cigarettes or any tobacco products. If you're bringing cigarettes from another country and get caught doing so, you'll be charged with huge fines.
