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

TL;DR: Singapore grants no duty-free concession or GST import relief for tobacco products—even a single cigarette must be declared, and duty and GST must be paid. It is illegal to import, possess, purchase, or use electronic vaporisers. Travellers carrying physical currency and bearer negotiable instruments with a combined value exceeding SGD 20,000 must submit a declaration. Medication rules depend on the active ingredients: controlled substances require prior HSA approval, while other eligible personal medications may be limited to a three-month supply and still require supporting medical documents.

No Duty-Free Tobacco Concession

Singapore grants no duty-free concession or GST import relief for cigarettes or other tobacco products.

If you bring cigarettes or other tobacco products into Singapore:

You must declare them and pay the required duty and Goods and Services Tax (GST). You may use Customs@SG up to 3 days before arrival; after successful payment, retain the receipt and use the Green Channel. Otherwise, declare them on arrival.
If you pass through the Green Channel (Nothing to Declare) with undeclared tobacco (even an opened packet), it is a customs offence.
All imported cigarettes and tobacco products must comply with Singapore's Standardised Packaging requirements. Non-compliant products will be disposed of at the checkpoint even if duty and GST have been paid.
Penalties: The checkpoint composition amount for a first failure to declare cigarettes is SGD 200 per packet, per 20 sticks, or part thereof. Serious cases, or cases in which the penalty exceeds SGD 5,000, may be prosecuted without an offer of composition.

Strict Ban on E-Cigarettes (Vapes)

Electronic vaporisers, related components, and refill liquids are prohibited in Singapore. The ban covers importing, selling, possessing, and using these products.

Arrival Action: Do not bring any vaporiser or related component to Singapore. ICA advises arriving travellers who nevertheless have one to declare it to checkpoint officers and comply with their instructions. Failure to declare may lead to a fine or referral to HSA.
Penalties: Since May 1, 2026, purchase, use, or possession can be punished by a fine of up to SGD 10,000. Importing vaporisers carries mandatory imprisonment of up to 9 years and a fine of up to SGD 300,000.

Cash Declaration (More Than SGD 20,000)

If the combined value of the physical currency and bearer negotiable instruments you carry exceeds SGD 20,000, or the equivalent in foreign currency, you must submit a declaration. Singapore does not impose a limit on the amount you may carry; this is a reporting threshold.

How to declare: Submit Form NP 727 online within 72 hours before entering or leaving Singapore, using ICA's e-727 service or the MyICA mobile app. A new declaration is required for each applicable entry or departure.
Why it matters: Failure to submit a full and accurate report is an offence under the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992. The penalty may be a fine of up to SGD 50,000, imprisonment for up to 3 years, or both; the CBNI may also be seized and, upon conviction, confiscated.

High-Risk Medications and Restrictions

Approval depends on a medication's active ingredients, not simply on whether it is sold over the counter or by prescription in another country.

Controlled Medications: HSA's current controlled-substance list includes ingredients used in some sleeping medicines, pain medicines, and ADHD medicines, such as codeine, alprazolam, zolpidem, amphetamine, lisdexamfetamine, and methylphenidate. Check the exact active ingredient and apply for approval at least 2 weeks before arrival when required.
Medications Not Requiring Approval: You may bring up to a 3-month supply only if the medication is lawfully prescribed to you or an immediate family member, contains no listed controlled or prohibited substance, is not in chewing-gum form, and is not a cell, tissue, or gene therapy product. Carry a valid prescription or doctor's letter, and keep each medication in its original, pharmacy-labelled packaging.
Prohibited Medications: Products containing prohibited substances such as cannabis or cannabis extracts cannot be brought in. HSA also prohibits personal imports of medications in chewing-gum form and cell, tissue, or gene therapy products.
Airside Transit: HSA approval is not required for personal medication kept within the transit zone without clearing immigration, but prohibited medication remains prohibited even during such transit.

Step-by-Step Customs Compliance Check

To ensure a smooth arrival at Changi Airport:

Use the Correct Declaration Route: Declare and pay duty or GST through Customs@SG before arrival when applicable, or use the Red Channel or a Customs declaration kiosk. If you are unsure, use the Red Channel or ask a Customs officer.
Check Prohibited and Controlled Goods: Ordinary chewing gum and electronic vaporisers are prohibited. Controlled goods require the relevant permit or authorisation before arrival and must be presented with the approval documents.
Prepare Separate Time-Sensitive Filings: Submit Form NP 727 within 72 hours before each applicable entry or departure. Apply to HSA at least 2 weeks before arrival if a medication contains a controlled substance.
