What is TradeNet, and how do Singapore import declarations work?
TradeNet is the electronic system through which every import, export, and transhipment declaration in Singapore is submitted. If you are importing anything commercially, your shipment passes through it — usually via a Declaring Agent rather than directly.

What TradeNet actually is
TradeNet is Singapore's national single window for trade declarations. Rather than filing separately with Singapore Customs and each controlling agency that has an interest in your goods, a single electronic declaration is submitted and routed to everyone who needs to see it. Approval comes back through the same channel. It is accessed through the Networked Trade Platform, and it is the mechanism behind the permit that authorises your shipment to enter Singapore.
Who submits the declaration
In practice, the overwhelming majority of importers do not file their own declarations. They appoint a Declaring Agent — a party registered with Singapore Customs to make declarations on behalf of others. The agent submits through TradeNet using their own access, and the declaration is made on your behalf as the importer. That distinction matters: the agent operates the system, but the accuracy of what is declared remains your responsibility as the party on whose behalf it is made.
What you need before anything can be submitted
Before a declaration can be made for your business, a few things generally need to exist:
- A Unique Entity Number (UEN) — the identifier issued when a business is registered in Singapore.
- An activated Customs Account with Singapore Customs, linked to that UEN.
- An arrangement for paying duties and GST, which for most importers means going through a Declaring Agent or having an Inter-Bank GIRO arrangement in place.
- A Declaring Agent appointed to act for you, unless you intend to register and file directly.
Timing: the permit comes before the goods
The most common practical mistake first-time importers make is treating the permit as something to sort out once the shipment lands. Import permits are generally required before the goods arrive, and cargo without a valid permit does not simply wait patiently — it accrues storage charges and, for time-critical shipments, misses its window entirely. If you are working backwards from an event date or an install slot, the permit application needs to be inside your timeline, not after it.
Where things go wrong
The system itself is reliable. What causes delay is almost always the quality of the information fed into it — a goods description too vague to classify, an HS code that does not match the actual product, a value that does not reconcile with the invoice, or a controlled good declared as though it were ordinary cargo. A declaration is a legal statement, and correcting one after submission is considerably more work than getting it right the first time.

Questions we get asked about this
Can I submit a TradeNet declaration myself?
It is possible to register as a Declaring Agent and file directly, but it involves registration with Singapore Customs, appropriate software or NTP access, and trained declarants. For businesses that import occasionally, appointing a Declaring Agent is almost always the practical route.
How long does a permit take to come through?
Straightforward declarations for uncontrolled goods are often processed quickly. Where a controlling agency has to review the declaration, it takes longer, and how much longer depends on the agency and the goods. Build in time rather than assuming same-day approval.
What happens if goods arrive without a permit?
The cargo cannot be released. It sits, accruing storage, until the declaration is sorted out — and if a controlling agency requirement was missed, sorting it out may involve an approval process that takes days or weeks. This is the scenario worth planning to avoid.
Is TradeNet the same as the Networked Trade Platform?
They are related but not identical. The Networked Trade Platform is the wider digital trade platform; TradeNet is the declaration system accessed through it. For most importers the distinction is academic — what matters is that declarations are submitted electronically and routed to all relevant agencies.
