Singapore Customs Guide: Vapes Ban, Tobacco Taxes, and Medication Rules

TL;DR: Singapore has some of the world's strictest customs laws. There is no duty-free allowance for tobacco products—even a single cigarette must be declared and taxed. Electronic cigarettes (vapes) are completely illegal to import or possess. Carrying equivalent to SGD 20,000 or more in cash requires a mandatory declaration. Certain over-the-counter medicines require prior approval or prescriptions.

The Absolute Zero-Duty Tobacco Rule

Unlike neighboring countries that allow one carton of cigarettes duty-free, Singapore grants no duty-free concession for any tobacco products.

If you bring cigarettes or other tobacco products into Singapore:

You must declare them at the Red Channel (Goods to Declare) and pay the required duty and Goods and Services Tax (GST).
If you pass through the Green Channel (Nothing to Declare) with undeclared tobacco (even an opened packet), it is a customs offence.
Penalties: First-time offenders face a composition fine of SGD 200 per packet or up to SGD 5,000 for larger quantities.

Strict Ban on E-Cigarettes (Vapes)

Electronic cigarettes, vaporizers, and e-liquids are completely outlawed in Singapore. This ban includes importing, selling, possessing, or using these products.

Transit Warning: Even if you are just transiting through Changi Airport and do not clear immigration, carrying e-cigarettes in your checked or cabin baggage is illegal and can be detected during security screenings.
Penalties: Possession, use, or purchase of a vape in Singapore carries a fine of up to SGD 2,000. Importing vapes can result in a fine of up to SGD 10,000 or imprisonment. Do not bring vapes into the country under any circumstances.

Cash Declaration (SGD 20,000 Limit)

If you are carrying physical currency or bearer negotiable instruments (such as traveler's checks) equivalent to SGD 20,000 or more, you must submit a declaration.

How to declare: You must submit the NP72 form electronically before arriving in or departing from Singapore. This can be completed via the ICA's online portal or the MyICA mobile app.
Why it matters: Failure to declare is a serious offence under the Corruption, Drug Trafficking and Other Serious Crimes Act, carrying a fine of up to SGD 50,000 or imprisonment for up to 3 years.

High-Risk Medications and Restrictions

Many common over-the-counter medications in other countries are classified as controlled substances in Singapore.

Controlled Medications: Sleeping pills, strong painkillers (containing codeine), or medications for ADHD require prior approval from the Health Sciences Authority (HSA). You must apply for approval at least 10 working days before travel.
General Medications: Standard cold tablets or aspirin do not need approval but must be for personal use, in reasonable quantities (maximum 3 months' supply), and accompanied by a doctor’s prescription or pharmacy label.

Step-by-Step Customs Compliance Check

To ensure a smooth arrival at Changi Airport:

Choose the Red Channel: If you are unsure whether an item is restricted or requires duty, always walk through the Red Channel and show it to the customs officers. Declaring an item will never result in a fine—at worst, it will be confiscated if prohibited.
Double-Check Your Luggage: Check your bags for forgotten items like chewing gum, herbal remedies containing animal parts, or electronic cigarettes.
Verify via eVisaFlow: When preparing your online SG Arrival Card (SGAC), make sure your personal information matches your passport MRZ exactly. Using the eVisaFlow Chrome Extension helps you automatically fill out and match passport data, avoiding typing errors.
