TradeNet Permit Rejected? 7 Messages and Your Next Move
Updated: 5 days ago
Two error messages are the ones Singapore Customs names for a rejected filing, and neither can be amended. If you have a TradeNet permit rejected, the screen shows a DCS Error or a CA/SC Reject. Singapore Customs' answer to both is the same: correct what was in error and submit a new permit application, which gets a new Unique Reference Number (Singapore Customs, updated 9 April 2026).
So the real question in the first hour isn't how to patch the permit. There's no permit yet. It's which reject you have, and whose desk the fix sits on.
Some fixes sit with your agent. Others wait on your own company's Customs Account, or on a licence held by a Competent Authority (CA). TradeNet itself processes more than 99% of declarations within 10 minutes (Singapore Customs e-guide, December 2024). When you lose hours after a reject, you lose them upstream of the system.
Updated 23 September 2026. Written for the operations or finance person whose declaring agent has just said the permit didn't go through. If you'd rather hand the whole thing over, our import and export permit service covers the filing from assessing your goods onwards.

Key takeaways
A TradeNet permit rejected by the system is not a permit. Customs asks for a new filing, and the new one carries a new URN (Singapore Customs, 2026).
An INVALID IMPORTER/EXPORTER EI/UEN reject is yours to fix: your Key Personnel activate the Customs Account, then the agent waits 4 working hours to file (AskGov, 5 June 2026).
A filing still pending that you know is wrong can be rejected at your request, through the CA or a Customs Enquiry Form (AskGov, 29 October 2025).
SFA's same-day cut-off for pending permits is 5:30pm from Monday to Thursday and 5:00pm on Fridays (SFA, 29 May 2025).
A typical new filing costs about S$3.19 in Customs fees, before any service provider's own charge (Singapore Customs, 18 February 2026).
TradeNet permit rejected: which message do you have?
Start with the words on the screen, not a guess from memory. Traders ask Customs this in public, in almost these words:
"Why is my permit application rejected? How should I proceed?" - a trader asking Singapore Customs, published on AskGov
Customs' reply is one line: check the TradeNet rejection messages issued. Good advice, but that's all of it. So here's what each published message points to, and who has to act on it.
TradeNet puts every filing into 1 of 3 states. It's approved and given a permit number, it's pending, or it's rejected with a code like DCS ERROR or CA/SC REJECT (Singapore Customs, 3 August 2026). Ask your agent for the exact text, not a paraphrase. One word in the message can change whose job the fix is.
What each published message points to
Message as published | What it points to | Whose desk | First move |
DCS Error | The filing was incomplete or had an error in it. | Your declaring agent | Correct the entries, file a new application. |
CA/SC Reject | It fell short of a requirement set by Singapore Customs or by another CA. | Customs or the CA's record | Find which requirement wasn't met before filing again. |
INVALID IMPORTER/EXPORTER EI/UEN | Your Customs Account might be inactive: never activated, or since deactivated. | You (your Key Personnel) | Activate the account, then wait 4 working hours. |
PLEASE CHECK TRADER EI/UEN (SFA) | An SFA licence that is invalid or not declared, or a UEN that doesn't match it. | You and SFA's licence record | Check the licence and the UEN on it. |
R05 (REJECTED BY SFA) | An incorrect establishment code. | Your agent, from your health certificate | Take the code from the health certificate. |
PLEASE CHECK PRODUCT CODE/ PRODUCT QUANTITY (SFA) | Product code and HS code not linked correctly, or an incorrect quantity unit. | Your agent, with your product facts | Re-match product code, HS code and unit. |
PLEASE CHECK BRAND NAME/ ITEM DESCRIPTION (SFA) | More than one brand or product in a single field. | Your agent, from your invoice | Split the items onto their own lines. |
AMENDMENT IS NOT ALLOWED - PERMIT VALIDITY PERIOD | A refused change to an approved payment permit, not a rejected filing. | Timing on the payment side | See the payment rule below. |
Where the table comes from: the two TradeNet messages are on the Customs error messages page. The UEN row is from AskGov. SFA's four texts sit in SFA's permit FAQ, and the last row is a Customs answer on AskGov.
One row needs care. The last message belongs to a permit already approved, so its fix sits on the payment side.
Customs doesn't publish a list of DCS Error sub-codes or CA/SC Reject reasons, and other authorities issue their own texts. If your message isn't in this table, don't match it to the nearest row. Send it to your agent word for word. Our note on obtaining a cargo clearance permit places both messages in the wider filing sequence.
Can you amend a rejected application?
No. A TradeNet permit rejected at the filing stage has no permit to amend. Customs' error pages for import, export and transhipment all give the same instruction. Here is the import wording:
"Please submit a new import permit application after rectifying the errors or omissions. A new Unique Reference Number (URN) will be issued for the new application." - Singapore Customs, Permit Validity and Error Messages (import), updated 9 April 2026
The export page says the same for a new export permit application, also updated on 9 April 2026. The transhipment page, updated 26 May 2026, repeats it again. So whichever way your goods are moving, you're looking at a fresh filing with a fresh URN. Nothing you do to the old one brings it back.
Where the amend-and-resubmit advice comes from
Now compare the line you'll hear most often: amend the details and resubmit. Even Customs' own TradeNet overview puts it loosely, which is reasonable as plain English but a dead end as a TradeNet instruction:
"If it is rejected, you will need to meet the requirements or make the necessary amendments before re-submitting the application." - Singapore Customs, What You Need to Know About TradeNet
In TradeNet, amending is its own filing type. You file it against an approved permit that is still valid, and Customs sets no limit on how many you make (Singapore Customs, 25 March 2026). A rejected filing never became a permit, so there's nothing for an amendment to attach to.
Your agent corrects the entries and files fresh. The old URN is finished. From then on, the new URN is the one you quote about the filing until approval, even on papers going to a CA (Singapore Customs, 2026).
Whose desk is the fix on?
Your agent's desk, for a DCS Error
This is the split nobody draws for you. Every reject sits on one of three desks, and the desk decides how long the fix takes.
A DCS Error means the filing was incomplete or contained an error (Singapore Customs, 2026). The entries were keyed, and they didn't hold up. That's the agent's to correct.
What you can do is answer fast when the agent asks you to confirm a value, a quantity or an HS code. If the agent needs a fact only you hold, like the supplier's name, the fix waits on you.
So keep the invoice and packing list within reach for the next hour. This is the reject you can clear from paperwork you already hold.
Your own desk, for INVALID IMPORTER/EXPORTER EI/UEN
This one surprises people, because it reaches you through the agent. One trader put it to Customs this way:
"I have been notified by my Declaring Agent of my unapproved permit application due to an invalid importer/exporter UEN. How should I resolve this?" - a trader asking Singapore Customs, published on AskGov
Customs' answer: your company's Customs Account might never have been activated, or it's been deactivated since. Your agent can't fix that. Only your Key Personnel, the people registered with ACRA or your UEN issuing agency, can activate the account (Singapore Customs, 17 February 2026).
Activation carries no Customs fee. You hear back within 4 working hours when no supporting documents are needed, or 3 working days when they are.
Once activation succeeds, your agent still waits 4 working hours before filing again (AskGov, 2026). Those are two separate waits from two Customs pages, so don't add them up as a promise.
The CA's desk, for a CA/SC Reject
A CA/SC Reject means the filing didn't meet a requirement of Singapore Customs or another CA. For controlled goods, that usually means a licence, a registration or a product code. Goods on the product code pair list need both CA product codes declared. Customs warns that a missing or partial product code can hold an application up or get it rejected (Singapore Customs, 3 June 2026).
SFA is the clearest worked example, because it publishes its texts. PLEASE CHECK TRADER EI/UEN points at your SFA licence: invalid, undeclared, or not tallying with your UEN. R05 (REJECTED BY SFA) flags an incorrect establishment code and sends the declarant back to the health certificate (SFA, 2025).
If you import food or alcohol, our guide to the alcohol import permit and licence shows how the two fit. Nobody on the declaring side can make a CA decide faster. So the record comes first, and the new filing second.
The goods description line behind some SFA rejections
Singapore Customs' Circular 09/2025, dated 14 October 2025, asks traders and declaring agents not to declare shortened HS or CA descriptions, or model numbers with no description, as the goods description. It wants 6 fields completed wherever they apply: the goods description, brand, model, the supplier or maker, end use, and remarks (Circular 09/2025).
The circular is an advisory. It doesn't say a short description gets rejected. SFA's own texts are more direct. SFA issues PLEASE CHECK BRAND NAME/ ITEM DESCRIPTION when one field holds two or more brands or products (SFA, 2025).
So when you resend the invoice, check that each item has its own line and its own brand. For the HS side of the same line, see getting the HS code chain right.

New application, amendment or withdrawal?
The verdict first. If the filing was rejected, the route is a corrected new application, sent as soon as the fix is in, for import, export and transhipment alike. The one exception is a fix on someone else's record, where the new filing waits for that record to change.
Most lost hours come from reaching for a later-stage tool. Each row below is a stage. It shows the route Customs sets and any time or fee on record:
Your situation | Route | Customs' condition | Time or fee on record |
Rejected with a DCS Error | New application | Rectify the errors or omissions first. A new URN is issued. | About S$3.19 per typical application |
Rejected over a licence, code or account (CA/SC Reject or INVALID IMPORTER/EXPORTER EI/UEN) | Fix the record, then a new application | The requirement has to be met before filing again. | 4 working hours after activation, where the account was the cause |
Pending approval, and you know it's in error | Ask for the pending filing to be rejected | Ask the CA, or submit a Customs Enquiry Form. | No time published |
Refused amendment: AMENDMENT IS NOT ALLOWED - PERMIT VALIDITY PERIOD | Wait on the payment side | Validity on a payment permit can't be extended until Customs has the duty or GST in hand. | Or 5 working days after you pay |
Sources: the Customs error messages page, the Customs fees page, and AskGov answers on account activation, pending filings and payment permit validity.
Three judgment calls
An entry error on a rejected filing: correct it and file now. A DCS Error is fixed in the entries, so the work starts the moment the facts are in front of your agent.
A CA/SC Reject tied to a licence or account: fix the record first. Filing the same entries again only repeats the reject and burns a URN. Clear the record, then file.
A pending filing you know is incorrect: stop it. Customs gives you a route to have it rejected on purpose, through the CA or a Customs Enquiry Form (AskGov, 29 October 2025). That beats unpicking a mistaken approval later.
An approved permit that turns out mistaken is a separate amend-or-cancel decision, covered in its own guide. If the permit has already been used for cargo clearance, see our note on fixing a declaration that is already wrong.

What starts costing time after a rejection
A rejected filing starts no permit clock, because there's no permit yet. An approved import permit usually runs to the approval date plus 9 working days. For dutiable goods leaving licensed premises, it's approval plus 1 working day (Singapore Customs, 2026).
Export permits get approval plus 9 working days, or 2 for dutiable goods from licensed premises (Singapore Customs, 2026). Transhipment goods moving on a through bill of lading, or a through air waybill, get approval plus 21 working days (Singapore Customs, 26 May 2026).
The time doesn't go into TradeNet itself. Three things eat the hours:
Account activation, where you can lose 4 working hours before your agent can file again (AskGov, 2026).
SFA's cut-off. SFA clears a pending permit on the day it arrives if it gets there by 5:30pm, Monday to Thursday. On Fridays the cut-off is 5:00pm. Miss it and you lose the day (SFA, 2025).
Sunday maintenance: TradeNet is down on Sundays from 4am to 8am (Singapore Customs, 2026).
Customs puts a typical filing at roughly S$3.19. The statutory fee is S$0.90 of that, and S$2.29 covers processing and messaging; third-party fees come on top (Singapore Customs, 2026).
Customs doesn't say whether a rejected filing is charged. Amending an approved permit adds S$0.21 (AskGov, 3 March 2026); the rest is in what customs clearance actually costs.
What to send your declaring agent in the first hour
Your agent works fastest when everything arrives in one message. Send these, in this order:
The rejection text, exactly as TradeNet shows it. A screenshot works. Your own summary doesn't.
The URN of the rejected filing.
The commercial invoice and packing list, plus the bill of lading or air waybill.
The HS code and any CA product codes you declared. Run them through the HS/CA Product Code Checker.
Your licence or registration number, with its expiry date, if the goods are controlled.
Your Customs Account status, checked by your Key Personnel, if the message mentions EI or UEN.
Why each one matters, and who usually holds it:
Item | Why your agent needs it | Who holds it |
Rejection text and URN | The text names the check that didn't pass. The URN has to be quoted before approval. | Your agent's screen; ask for a copy |
Invoice and packing list | Values, quantities, units and each item's own line. | Your finance or purchasing team |
Brand, model, supplier, end use | Circular 09/2025 expects these 6 product fields in full where they apply. | Your supplier, via the invoice |
HS code and CA product codes | Product code pairs must both be declared for listed goods. | You, checked in the Customs tool |
Licence or registration | Approval and documents must be in place before filing. | You, from the authority |
Customs Account status | Only Key Personnel can activate it. | Your company's Key Personnel |
Sources: TradeNet overview for the URN, controlled items overview for product codes and uploads, Circular 09/2025 for the 6 fields, and the Customs Account page for Key Personnel.
If this is your first filing with this agent, read how an import permit application works first. If you're unsure who files what, read who declares your shipment. The field-by-field view sits in import permit declarations explained.
Export and transhipment filings follow the same new-application rule. Those permit types are set out on our re-export permit service and transhipment permit service pages. If a buyer is also waiting on a certificate, a clean permit keeps your Certificate of Origin applications built on the right figures.
What if TradeNet itself is the problem?
Sometimes the problem is the system, not the entries. Rule out the obvious thing first. If the screen showed a DCS Error or a CA/SC Reject, TradeNet did its job and the filing is what needs fixing. A help desk can't change that.
A frozen screen or a submission that hangs is different. For system faults, Customs points you to the CrimsonLogic Help Desk, 6887 7888 (Singapore Customs, 2026). When your agent calls, they'll need the URN, the application type and the error messages.
Problems with your agent's filing software go to its front-end provider instead. On a Sunday morning, check the maintenance window first.
Send the rejection message and get a written answer
If your permit came back rejected and you aren't sure which route applies, send us what you have. That's the rejection message exactly as TradeNet shows it, the URN, the commercial invoice, the packing list and the HS codes you declared.
We'll reply in writing on the route: new application, amendment, withdrawal, or none yet. We'll also say what we'd need from you. You'll get scope, not a price, and not a promise. Nobody can promise an outcome or make Customs or a CA decide faster.

Frequently asked questions
Can I amend a TradeNet permit rejected by Customs?
No. A rejected filing never became a permit, so there's nothing to amend. Singapore Customs asks you to rectify the errors or omissions and submit a new permit application, which receives a new Unique Reference Number. Amending works only on an approved permit that is still valid.
What is the difference between a DCS Error and a CA/SC Reject?
A DCS Error means your filing was incomplete or contained an error, so the entries need correcting. A CA/SC Reject means it didn't meet a requirement of Singapore Customs or another Competent Authority, often a licence or product code. Both end the same way: a corrected new application, with a new URN.
Why is my permit application rejected for INVALID IMPORTER/EXPORTER EI/UEN?
Customs says your company's Customs Account might be inactive. Only your Key Personnel registered with ACRA or your UEN issuing agency can activate it, whether it was never activated or later deactivated. If no supporting documents are needed, the outcome comes within 4 working hours. After that, your declaring agent waits another 4 working hours to file.
How long does a resubmitted permit take?
Singapore Customs reports that over 99% of TradeNet declarations finish processing inside 10 minutes. Filings that need a Competent Authority take longer. SFA works on pending permits that same working day when they land by 5:30pm Monday to Thursday, or by 5:00pm on a Friday. No one can promise how an authority will decide, or make it decide faster.
Can I stop a permit application that is still pending?
Yes. Customs says a pending filing can be rejected at your request: ask the Competent Authority, or send a Customs Enquiry Form. It's a sensible move when you know the filing is in error. It keeps a bad filing from being approved and then needing a separate amendment or cancellation afterwards.
What does a new permit application cost?
Singapore Customs puts a typical TradeNet permit filing at about S$3.19. That covers a S$0.90 statutory fee and S$2.29 in processing and messaging charges; third-party service fees are extra. Customs doesn't publish whether a rejected filing is charged. Each amendment to an approved permit costs S$0.21 in messaging fees.
