Singapore Custom Broker Services: 5 Things to Hand Over
Updated: Oct 25
A custom broker in Singapore is your declaring agent: it applies for the import permit in TradeNet on your company's behalf, and only declaring agents can submit new trade declarations. You and your agent keep the trade records for 5 years or more after a permit is approved. Customs' free Trader Notification reports each permit approved, cancelled or amended under your UEN.

Key takeaways
Who the importer is, and what that means for your permit, is set out in our import permit declarations guide.
Only declaring agents can submit new trade declarations in TradeNet. Customs lists two options: appoint a declaring agent, or register as one yourself.
You can appoint up to 20 declaring agents and update the list at any time.
You and your declaring agent each have to keep trade documents for 5 years or more, counted from permit approval.
Customs' free Trader Notification service tells you the permit number, the agent's name and the approval date when a permit under your UEN is approved, cancelled or amended.
A typical import permit is valid for the approval date plus 9 working days, so if a shipment slips, raise it with whoever files your permit before it lapses.
The Role of Singaporean Custom Brokers: What Does One Do for Your Business?
Singapore Customs' term for the entity that files your permit is a declaring agent. It applies for the permit through a declarant, on behalf of the declaring entity, which can be your company. This guide uses customs broker and declaring agent for the same role. Declaration Nexus is a Singapore customs broker and declaring agent.
In TradeNet, new trade declarations are reserved for declaring agents, and so are amendment, cancellation and refund applications for permits. A company that isn't registered as a declaring agent appoints one. Once your Customs Account is active, Customs lists two options: appoint a declaring agent, or register as one and apply for a TradeNet User ID. Our guide to filing your own TradeNet permits or using a declaring agent sets out the trade-off.
Who counts as the importer?
The definition, with Customs' invoice and consignee example, is in our import permit declarations guide. The FAQ below answers the short version.
Typical Services Offered by Singaporean Custom Brokers: What Customs Says You Declare, Present and Keep
Customs brokerage services, also called customs broker services, start from what Customs itself says you declare, present at a checkpoint and keep as records. This table shows what you declare, what you present and what you keep, with the Customs page behind each row.
Item | What Customs says | Customs source |
In place before anyone files: a UEN and an activated Customs Account | Customs says no import permit application can be submitted until your Customs Account is activated. Only Key Personnel such as an owner, partner or director can activate it, and activation needs no fee to Singapore Customs. | |
Declare: container number and shipper seal number, for containerised cargo | When applying for a customs permit, you must declare both. | |
Declare: HS code, and CA product codes if the item is controlled | Customs offers the HS/CA Product Code Checker to identify the HS code, check whether your item is controlled and find the CA product codes. | |
Obtain and upload: Competent Authority approval and supporting documents, for controlled items | Customs sets out three steps before you apply for controlled items. First, identify the HS code and the relevant Competent Authorities. Second, check whether more than one Competent Authority's requirements apply. Third, meet those requirements, get approval where applicable and upload the supporting documents in the TradeNet application. Customs notes that missing documents may delay processing. | |
Keep: commercial invoice, packing list, bill of lading or air waybill | Customs lists these among the documents you and your declaring agent must keep for at least 5 years from permit approval. |
Controlled items add the Competent Authority row above. Our guide to whether you need a licence, a permit or both shows how to tell, and the HS code declaration guide covers the code.
How long does Customs take to approve a Customs Account?
Customs says you hear the outcome within four working hours if no supporting documents are needed. With complete supporting documents, it comes within three working days.
What does the broker file in TradeNet?
Import permit applications go through TradeNet, either in software from an approved vendor or in the Government Front-End Application. Those channels are how you or your declaring agent process import declarations and receive notices of approved permits. TradeNet returns the approved permit to the trader through the front-end solutions.
The job | Who can do it in TradeNet | What comes back or what to do next |
Submit new trade declarations | Only declaring agents | TradeNet returns the approved permit to whoever filed it. Ask your agent for a copy, because you will need it for the permit conditions and checkpoint rules below. |
Amend, cancel or refund a permit | Only declaring agents | See our guide to amending or cancelling a permit. |
Watch permits approved, cancelled or amended under your UEN | You, through Key Personnel such as an owner, partner or director, or Authorised Personnel in your Customs Account | Sign up for the free Trader Notification service, explained below. |
What does the free Trader Notification tell me?
Customs says you can sign up for free. It sends the permit number, the declaring agent's name and the approval date when a permit under your UEN is approved, cancelled or amended. Key Personnel such as an owner, partner or director can sign up, and so can Authorised Personnel in the Customs Account.
Use the notification to check each approved permit against the shipment you asked for. We would rank it first among the steps here: it costs nothing and reaches you for each permit approved, cancelled or amended under your UEN.

How do I check the status of my permit application?
Customs says you can check status through your TradeNet front-end solution or the TradeNet back-end interface. Status types include Approved, which comes with a permit number, Pending, and Rejected, which comes with error codes such as DCS ERROR or CA/SC REJECT.
TradeNet is unavailable on Sundays from 4am to 8am for maintenance. If the status shows Rejected, read our guide to what to do after a rejected permit.
What is the URN on my TradeNet application?
Every application submitted through TradeNet is assigned a Unique Reference Number, or URN. Customs says to quote the URN in all subsequent references to the application before approval, including any documents submitted to Competent Authorities.
How long is an import permit valid?
How long an import permit stays valid, and when to extend it, is covered in our import permit declarations guide. The numbers table below keeps the figures. If a shipment slips, raise it with whoever files your permit before the permit lapses.
What stays your responsibility after the permit is approved?
Customs lists commercial invoices, bills of lading or air waybills, packing lists, certificates (origin, analysis, insurance), books of accounts and any documents showing your terms of trade. Customs can ask to see them at any point. You can store scanned images instead of physical copies if they meet Customs' guidelines for digital trade documents.
Follow the permit conditions. Some carry a deadline. Condition Z02, for example, gives you 48 hours from approval to submit the permit with invoices and transport documents through Customs eServices.
Check the checkpoint rule for your mode of import. In Customs' summary table, containerised sea imports are marked No for presenting the permit and documents at the checkpoint. Customs' page says containerised air or land imports must present four items at the checkpoint: a copy of the customs permit, the commercial invoice, the packing list and the Air Waybill or consignment note (not applicable for land imports). Its summary table adds that they are presented only if the permit conditions require, so read your permit conditions.
If you plan to clear a shipment in parts, Customs says to show the same permit each time until all of it is cleared. Woodlands and Tuas checkpoints don't allow part clearance. Tell whoever files your permit before you clear in parts.
Should you appoint a broker or file the permits yourself?
Customs lists both. Our view: if you don't want to register your own company as a declaring agent, appoint one, because only declaring agents can submit new trade declarations. We would not appoint an agent that won't say which permit types it files. The trade-off is in the file-it-yourself comparison, with cost lines in what customs clearance costs and a second view of the costs.
