Shipping from China and Hong Kong to Singapore: customs, GST and free trade zones

Customs authority: Singapore Customs, through the TradeNet single window
Duty: None on almost all goods. Only liquor, tobacco, vehicles and petroleum are dutiable
GST: 9 percent, payable at import unless a relief scheme applies
Free trade zones: Cover the port and airport, allowing storage without GST
Relief schemes: Major Exporter Scheme and zero GST warehousing suspend GST for qualifying traders
Main entry points: PSA terminals and Tuas by sea, Changi by air

That makes Singapore structurally different from every other destination in this list. There is no tariff classification argument to have, no preferential origin to chase, and no duty to finance. The regulatory attention goes instead into controlled goods, and the operational value goes into the country role as a hub.

Singapore free trade zones cover the port and airport areas, and goods can be held there without GST being payable. Combined with the busiest transhipment port in the world, that makes the country the default regional distribution point for Southeast Asia.

Clearance runs through TradeNet, a single window that has been operating for decades and is genuinely fast. Permits are issued electronically and a compliant shipment moves quickly.

Where cargo lands

Main freight and distribution centres

Singapore

A city state, so the market, the port, the airport and the logistics infrastructure are effectively one location.

Jurong and Tuas

The industrial and port west, where the new consolidated port and much of the warehousing sit.

Changi

The airport and its logistics park, central to high-value and time critical regional distribution.

Sea freight

Ports of entry and what they mean for your cargo

PSA Singapore terminals

Among the busiest container ports in the world, with connections to virtually every trade lane and unmatched transhipment options.

Tuas Port

The new consolidated mega port progressively taking over operations, designed for very large vessels and high automation.

Jurong Port

Handles bulk, breakbulk and project cargo that does not suit a container terminal.

Singapore is first and foremost a transhipment hub. A very large share of the boxes passing through are not entering the country at all, and structuring a movement to use that deliberately is often better than treating Singapore as a destination.

Transit from South China is short and services are constant, so scheduling is rarely the constraint.

For regional distribution across Southeast Asia, holding stock in a Singapore free trade zone or bonded facility and releasing it market by market is a well-established and efficient model.

Air freight

Airports and when air is the right answer

Changi (SIN)

A major global air cargo hub with extensive direct capacity, excellent handling and a dedicated logistics park in the free trade zone.

Seletar (XSP)

Smaller airport used for business aviation and some specialised cargo operations.

Changi combines connectivity with handling quality, which makes it a strong choice for high-value regional distribution rather than only for cargo destined to Singapore itself.

Sea to air routings through Singapore are a genuinely useful tool: ocean freight from China, then air onward into Southeast Asia, India or Australia, at a fraction of full air cost.

Indicative transit times

How long the movement usually takes

Sea FCL, South China to SingaporeAround 4 to 9 days port to portVery frequent services and short transits.
Sea LCL, South China to SingaporeAround 10 to 16 days door to doorExcellent consolidation frequency given the volume on this lane.
Air freight, Hong Kong or South China to SingaporeAround 2 to 4 days door to doorFrequent direct services including handling and clearance.
Onward regional distributionAround 1 to 7 daysTo Malaysia, Indonesia, Thailand, Vietnam and beyond, by sea, air or road.

These ranges are indicative and exist to help you plan. Real transit time depends on the service, the season, the routing and the clearance itself, and we confirm it per shipment rather than publish it as a promise.

Customs

How clearance into Singapore actually works

The competent authority is Singapore Customs.

There is no import duty on almost all goods. Only liquor, tobacco, motor vehicles and petroleum products are dutiable, which removes the entire tariff classification and preferential origin exercise for a typical commercial import.

GST at 9 percent is payable at import unless a relief scheme applies. Registered businesses recover it, but the cash still moves unless a suspension scheme is in place.

The Major Exporter Scheme and zero GST warehousing allow qualifying traders to suspend GST at import rather than pay and reclaim. For companies importing in volume, particularly for re-export, this is the single most valuable arrangement available.

Free trade zones cover the port and airport areas. Goods in them are not treated as imported, so they can be stored and re-exported without GST arising at all.

Even though duty is not the issue, controlled and prohibited goods are policed strictly, and permits through TradeNet are required for a wide range of items.

Documentation

What you need to have ready

Commercial invoice

Value, terms and a clear description consistent with the transport document.

Packing list

Piece counts, weights and dimensions per package.

Bill of Lading or Air Waybill

The transport contract and the release instrument.

TradeNet permit

The electronic import permit, required for imports and for movements in and out of free trade zones.

Unique Entity Number

Of the Singapore registered importer, with a customs account activated.

GST relief scheme documentation

Where the Major Exporter Scheme or a zero GST warehouse is being used.

Controlled goods permits

From the relevant competent authority where the goods are controlled.

Certificate of origin

Rarely needed for Singapore duty purposes, but often required for onward movements.

Controlled and restricted goods

What gets stopped, and why

Controlled goods are policed strictly despite the open trade regime. Pharmaceuticals, telecommunications equipment, chemicals and many other categories require permits from their competent authority.
Prohibited items, including chewing gum in commercial quantities and various other goods, are enforced without exception.
Drugs offences carry extremely severe penalties. Cargo integrity and knowing what is in the container matter more here than almost anywhere.
Food products require approval from the Singapore Food Agency with their own registration and labelling requirements.
Strategic and dual use goods fall under a strict permit regime, reflecting Singapore role as a transhipment hub.
Wood packaging must comply with ISPM 15.

Working with Velonex

What clients usually bring us in for on this lane

Companies distributing across Southeast Asia, who should be holding stock in a Singapore free trade zone or bonded facility rather than importing separately into each market.
Sea to air routings through Changi, which cut cost substantially against flying the whole way from China.
Traders importing in volume who are paying and reclaiming GST when a suspension scheme would remove the cash movement entirely.
High-value electronics and pharmaceuticals, where Changi handling quality and secure facilities are a real advantage.
Cargo continuing beyond Singapore, where the transhipment connectivity is the reason to route through here in the first place.
