Declaring Agent for Regular Imports Singapore: Set Up Once
A declaring agent for regular imports into Singapore can only file your permits once your own setup is done. That means a UEN, an activated Customs Account, an appointed agent, a way to pay GST and, for processed food, SFA registration. After that, each batch needs a final commercial invoice, a packing list and an In-Payment permit, one per lorry if the goods come by road through Woodlands or Tuas.
Say you bring in small batches of food from Malaysia every month. You want each batch to work the same way: send the papers, the goods clear, next month repeat. Traders ask Singapore Customs the starting question in almost these words:
"I will be bringing commercial goods into Singapore from Malaysia. What permit do I need?" (trader question on AskGov, July 2024)
The permit Customs names in reply is the In-Payment "GST (including Duty Exemption)" permit, which is presented to the ICA officer when the goods arrive (Singapore Customs on AskGov, July 2024). Which permit type fits which shipment is a separate decision, covered in our guide to the In-Payment permit in Singapore. This guide is about the routine around it: what you set up once, and what repeats with every batch.
Updated 29 October 2026. Declaration Nexus is a Singapore customs broker and declaring agent. We prepare and file the TradeNet permit through our import and export permit service. A declaring agent files the permit; it does not move the goods. The lorry from Malaysia is a separate transport job, and transport companies such as IFG Shipping write about that side.
KEY TAKEAWAYS

What you set up once, and what repeats every shipment
Most items in a regular import routine are done once, and most of those can only be done by you, the importer. The table splits the two. Lead times are the ones Singapore Customs and SFA publish.
Item | Once or every batch | Who does it | Published lead time |
UEN (company registration) | Once | You | Needed before anything else |
Activate the Customs Account | Once | Your Key Personnel only | 4 working hours, or 3 working days after complete documents |
Appoint your declaring agent(s) | Once, update as needed | You | Up to 20 agents, list can change at any time |
Own IBG with Customs (optional) | Once | You | Usually 3 to 4 weeks |
SFA registration (processed food for sale) | Once | You | At least 1 working day after a complete application |
ERSP establishment code (listed Malaysian food only) | Once per manufacturer | You, with your supplier | Gathering proof can take a month or longer |
Update company particulars | When they change | You | Within 7 days of the change |
Final commercial invoice and packing list | Every batch | You, to your agent | Before filing |
In-Payment permit, one per lorry | Every batch | Your declaring agent | Valid approval date + 9 working days |
Import GST at 9% | Every batch | Paid by IBG, yours or the agent's | On each permit |
Keep supporting documents | Every batch | You | 5 years |

The first seven rows decide whether your second batch goes as smoothly as your tenth, and most of them sit with you, not with your agent. Some provider pages sell recurring support as something you buy from the agent. Our view is narrower: the agent's side of a routine is filing each permit correctly from complete papers. The routine itself is only as steady as the setup you finish before the first lorry is booked.
The one-time setup: UEN, Customs Account and your declaring agent
Before any import permit can be submitted, the importer needs a UEN and an activated Customs Account (Singapore Customs, 2026).
Only Key Personnel can activate the account: an owner, partner or director of the business. Activation costs nothing in Customs fees.
Customs gives an outcome within 4 working hours when no supporting documents are needed, or within 3 working days of receiving complete documents. After approval, your declaring agent can use your UEN for permit applications (Singapore Customs, 2026).
The account also needs looking after. When your company details change, Customs gives you 7 days from the effective date to update them in the account.
If an agent's filing comes back with an "invalid importer UEN" message, Customs points to two possible causes: an account that was never switched on, or one that has since been switched off. Once it is activated, the agent can apply again after 4 working hours (AskGov, June 2026).
Appointing a declaring agent for regular imports
Customs lets traders appoint a declaring agent that is a registered TradeNet user, and suggests searching online to find one. Agents may charge service fees on top of Customs' own (AskGov, February 2025). Each importer may name as many as 20 agents, and the list can be edited whenever you like (Singapore Customs, 2026). For more on who files a permit and in whose name, see who files an import permit, and in whose name.
Turn on Customs' free Trader Notification while you are in the account. Every time a permit under your UEN is approved, cancelled or amended, you get the permit number, the agent's name and the approval date. On a payment permit, the email adds the duty and/or GST to be paid (Singapore Customs, 2026). For a regular importer, that email is your own running check on every batch filed in your name.
If your volume grows and you have staff who can do the filing, registering as your own declaring agent is the other route. We compare the two in filing your own TradeNet permits instead.
Paying GST on every batch: your IBG or the agent's
Import GST is charged at 9% on the CIF value plus duties and other charges, and it is payable whether or not your company is GST-registered (IRAS, 2026). So every batch carries a GST payment, and you need to decide once which bank account it comes from. How the value is built is explained in how customs value and import GST are worked out.
Singapore Customs' setup checklist gives two routes. Your agent can pay from its own IBG on your behalf. Or you open an IBG of your own and authorise the agent to draw on it (Singapore Customs, 2026). If you have no IBG set up with Customs, the duty and GST come out of your agent's IBG by default, and agents may add a service fee for that (Singapore Customs, 2026).
For a regular importer, your own IBG is usually worth the wait. Customs puts the processing time at 3 to 4 weeks in most cases (Singapore Customs, 2026), but you only wait once. If you change the bank account later, your declaring agents do not need to be authorised again.
Whichever route pays, keep your company as the importer on the permit. To claim the import GST back as input tax, IRAS needs your business named as importer on the permit (IRAS, 2026).

Importing food from Malaysia: SFA registration and the ERSP check
To import processed food for sale, you need to register with the Singapore Food Agency. A licence is a different thing: SFA uses licences for meat, fish, fresh fruit and vegetables, and shell eggs (SFA, 2026). SFA gives biscuits, cooking oil and mineral water as examples of processed food.
The registration sits on top of the Customs setup. SFA wants a valid UEN that is already active with Singapore Customs, and its review of a complete application needs 1 working day at minimum. Its general requirements include sending SFA an original GIRO form (SFA, 2026). From then on, each food consignment gets its own TradeNet import permit, and SFA lists its permit fee for processed food as "No fees required".
Malaysian food needs one more check. Under SFA's Enhanced Regulated Source Programme (ERSP), listed processed foods from Malaysia must come from registered establishments. The list covers edible oil, mooncakes, dried beancurd products, kueh and ready-to-eat cooked food, and infant formula and infant cereal (SFA, 2026).
If your product is on that list, plan for it before you book the first lorry. SFA says gathering the proof can take a month or longer. It then issues an establishment code for each manufacturer, which goes into the CA/SC Code1 field of the permit. With every consignment, send your agent the invoice, the packing list and the manufacturer's licences.
If you are not sure which category your product falls into, ask SFA before the first batch. The category decides whether the ERSP step applies, so do not guess it from the label.

Every shipment: the documents your agent needs, and when
With the setup done, each batch is a short loop. Customs' own best practice is to give your declaring agent full supporting documents (Singapore Customs, 2026). In practice that looks like this:
Send your agent the final commercial invoice and the packing list for the batch. Customs advises against pro-forma invoices.
Make sure the declared value includes freight and insurance, and list any samples or free-of-charge items. They need declaring too. A clear goods description helps here; see writing a goods description Customs accepts.
Tell your agent how many lorries the batch will use. At Woodlands and Tuas there is no partial clearance: Customs needs one permit application per container or vehicle, and part of the invoice can be declared on each (AskGov, February 2025).
Your agent files the In-Payment permit under your UEN. Your Trader Notification email confirms the permit number and the GST payable.
Time the lorry to the permit. An In-Payment import permit is typically valid from its approval date plus 9 working days, and your agent can extend it in TradeNet while it is still valid (Singapore Customs, 2026). More on timing is in how long customs clearance takes.
Give the driver three papers for the checkpoint: a permit copy, the invoice and the packing list. Customs requires all three for land imports (Singapore Customs, 2026).
File the invoice, packing list and permit together. Customs asks you to keep supporting documents for 5 years.
For ERSP-listed food, add the manufacturer's licences to step 1 every time.
Why regular batches get delayed, and the fix for each
These are the gaps Customs' and SFA's own guidance points to, each with a fix you can build into the routine.
What holds the batch up | The fix |
A pro-forma invoice sent instead of the final one | Ask your supplier for the final commercial invoice with each batch |
Freight and insurance left out of the value | Send the freight and insurance figures with the invoice |
Two lorries on one permit at Woodlands or Tuas | One permit per vehicle, with part of the invoice on each |
The permit runs past 9 working days before the lorry crosses | Ask your agent to extend it in TradeNet while it is still valid |
"Invalid importer UEN" on the filing | Check the Customs Account is active and particulars were updated within 7 days |
An ERSP-listed food with no establishment code | Start the ERSP step a month or more before the first batch |
Samples or free items in the lorry but not on the permit | List them on the packing list and declare them |

Frequently asked questions
Which customs declaring agent handles recurring imports for SMEs in Singapore?
When you choose a declaring agent in Singapore, check three things. The agent files under your own activated UEN, so you stay the importer for GST. It takes your invoice and packing list for every batch. And it tells you the permit type before filing. Customs points traders to declaring agents that are registered TradeNet users. Declaration Nexus is a Singapore customs broker and declaring agent that prepares and files TradeNet permits.
How do I import food from Malaysia to Singapore in small batches every month?
Set up once: a UEN, an activated Customs Account, SFA registration for processed food, and the ERSP establishment code if your product is on SFA's Malaysia list. Then for every batch, send your declaring agent the final invoice and packing list. The agent files one In-Payment permit per lorry, and GST at 9% is paid through IBG (IRAS, 2026).
Do I need a new permit for every shipment?
Yes. SFA expects a TradeNet import permit for each food consignment, and at Woodlands and Tuas Customs wants one permit per container or vehicle. What does not repeat is the setup: your Customs Account, your agent appointment, your IBG and your SFA registration carry over from batch to batch.
Can one permit cover two lorries?
Not at Woodlands or Tuas. Customs does not allow partial clearance there, so it asks for one permit application per container or vehicle. If one invoice covers goods split across two lorries, part of the invoice can be declared on each permit. Tell your agent how many vehicles a batch will use before it files.
Can I use more than one declaring agent?
Yes. Singapore Customs allows up to 20 appointed declaring agents per importer, and you can change who is on that list whenever you need to. If you change the bank account behind your IBG, the agents you have appointed do not need to be authorised again. Trader Notification shows which agent filed each permit under your UEN.
How long is an import permit valid?
An In-Payment import permit is typically valid from its approval date plus 9 working days. If the goods will not arrive in time, your agent can extend it in TradeNet while it is still valid. For a monthly importer, that window is the reason to file each batch close to when the lorry is booked, not weeks ahead.
