Step 1: Identify Prohibited and Restricted Items

Before you even make a purchase, you must determine if the item can legally enter Singapore. Singapore has some of the strictest customs regulations in the world, and non-compliance can lead to fines or the destruction of your goods.

Prohibited Items

These items are strictly banned. Do not attempt to ship them under any circumstances:

  • Chewing Gum: Except for certain dental or nicotine gums approved by the Health Sciences Authority (HSA).
  • E-cigarettes and Vaporizers: All electronic cigarettes and related components are prohibited.
  • Firecrackers and Pyrotechnics: Any explosive material is banned for safety reasons.
  • Scanning Receivers: Certain telecommunication equipment requires specific licensing.

Restricted and Controlled Goods

Restricted items are not banned but require approval from relevant authorities. For example, health supplements and cosmetics are regulated by the HSA. If you are unsure about a specific product, it is always a good idea to check our FAQ for a detailed list of controlled substances and the permits required for 2026 shipments.

Step 2: Verify Package Size and Weight Constraints

Size matters when shipping across the Pacific. Most international couriers have strict volumetric and physical weight limits. In 2026, the standard maximum length for most air freight parcels to Singapore is 150cm, and the maximum weight per individual box usually caps at 30kg for standard residential delivery.

If you are shipping oversized items like furniture or large electronics, you must account for "Dimensional Weight." This is a calculation based on the volume of the box rather than its actual weight. To avoid surprises, you should estimate shipping costs to Singapore using a volumetric calculator before finalizing your order from US retailers.

Step 3: Understand GST and Import Duty Thresholds

As of 2026, Singapore maintains a Goods and Services Tax (GST) of 9% on all imported goods. It is crucial to distinguish between Low-Value Goods (LVG) and standard imports:

Category Value Threshold Tax Requirement
Low-Value Goods Under S$400 9% GST applies (collected at point of sale or by forwarder)
Standard Imports Over S$400 9% GST + potential Customs Duties

For high-value items like luxury watches or jewelry, additional excise duties may apply. Always keep your invoices ready to prove the transaction value to Singapore Customs.

Step 4: Prepare Accurate Documentation

Customs officers in 2026 rely heavily on digital declarations. Ensure your merchant provides a detailed commercial invoice. The description should be specific; for example, instead of writing "Electronics," write "Wireless Bluetooth Headphones." Accurate descriptions help prevent your package from being flagged for manual inspection, which can delay delivery by several days.

Step 5: Choose a Reliable Package Forwarder

The final step is selecting a partner that understands the nuances of the US-to-Singapore route. Using a reliable package forwarder like comGateway allows you to shop from US stores that don't ship internationally. They provide a US tax-free address, which can save you up to 10% on US sales tax before the item even leaves the country.

By following these five steps, you can navigate the complexities of international logistics with confidence. Whether you are grabbing the latest tech or fashion essentials, staying informed about 2026 regulations ensures a seamless shopping experience from the USA to your doorstep in Singapore.
