Duties and Dutiable Goods Overview
Learn which goods are subject to duty in Singapore, how duties are calculated, and the categories of dutiable and non-dutiable goods.
In Singapore, certain goods are subject to customs duty and/or excise duty when imported or manufactured.
Customs Duty: Levied on imported goods.
Excise Duty: Levied on goods manufactured in, or imported into, Singapore.
Goods not subject to customs or excise duty are non-dutiable, although GST may still apply unless exempted.
Types of Duty Rates
Duties are charged using either:
Ad valorem rate – A percentage of the goods’ customs value
Example: 20% of customs valueSpecific rate – A fixed amount per unit of weight or quantity
Example: S$446 per kilogramme
Categories of Dutiable Goods
There are four categories:
Intoxicating liquors
Tobacco products
Motor vehicles
Petroleum products and biodiesel blends
Refer to the list of dutiable goods for the specific duty rates.
Examples of Duty Calculation
Below are examples showing how duties are calculated for each category.
1. Intoxicating liquors
a) Liquors charged per litre of alcohol
Formula
Duties payable = Total quantity (litres) × (Customs duty + Excise duty) × Alcoholic strength (%)
Example
Company A imports 75 litres of stout with 5% alcohol strength.
Customs duty = S$16 per litre of alcohol
Excise duty = S$60 per litre of alcohol
Duties payable = 75 × (16 + 60) × 5% = S$285
b) Liquors charged on dutiable content (weight/volume)
Formula
Duties payable = Dutiable content (kg) × Customs duty rate
Example
1 kg of alcoholic composite concentrate contains 0.2 kg of powdered alcohol.
Customs duty = S$113 per kg
Duties payable = 0.2 × 113 = S$22.60
2. Tobacco Products
a) All tobacco products except cigarettes
Formula
Duties payable = Weight (kg) × Excise duty rate
Example
Company A imports 100 kg of tobacco stems.
Excise duty = S$446 per kg
Duties payable = 100 × 446 = S$44,600
b) Cigarettes
Formula
Duties payable = Number of sticks × Weight per stick (rounded up to nearest gramme) × Excise duty rate
Example
Company A imports 100 sticks weighing 1.5 g each.
Duty rate = S$0.491 per gramme per stick
Weight is rounded up to 2 grammes.
Duties payable = 100 × 2 × 0.491 = S$98.20
3. Motor vehicles
Formula
Duties payable = Customs value × Excise duty rate
Example
Company A imports a motor car that was bought at S$100,000 on Free on Board (FOB) incoterms.
Freight, handling, insurance = S$1,000
Customs value of car = S$101,000
Excise duty = 20%
Duties payable = 101,000 × 20% = S$20,200
4. Petroleum products and biodiesel blends
a) Petroleum products
Formula
Duties payable = Volume × Excise duty rate
Example
Company A imports 100 litres of unleaded, unblended motor spirit (RON 97+).
Duty rate = S$7.90 per dal
(1 dal = 10 litres)
Volume in dal = 100 ÷ 10 = 10 dal
Duties payable = 7.90 × 10 = S$79
b) Compressed natural gas (Cng)
Formula
Duties payable = Weight (kg) × Excise duty rate
Example
Company A imports 50 kg of Cng.
Duty rate = S$0.20 per kg
Duties payable = 50 × 0.20 = S$10
c) Biodiesel blends
Formula
Duties payable = Volume of diesel × Excise duty rate
Example
Company A imports 1,000 litres of biodiesel blend containing 100 litres of diesel.
Duty rate = S$2.00 per dal (1 dal = 10 litres)
Volume in dal = 100 ÷ 10 = 10 dal
Duties payable = 2 × 10 = S$20
