Singapore — eCO
Chamber-endorsed Ordinary Certificates of Origin and Certificates of Processing for goods leaving Singapore, filed electronically through CrimsonLogic to your chamber of commerce.
Read Customs filing first for the flow. This page covers what is specific to the eCO.
Electronic filing has been mandatory since 1 August 2026 (Singapore Customs Circular 07/2026). There is no grace period and no paper route.
This is not the TradeWeb CO
Two different documents share the same three letters. They are issued by different bodies, on different forms, through different systems.
Issued by | Filed through | Documented at | |
|---|---|---|---|
Ordinary CO / CP (eCO) | One of the Singapore chambers of commerce | CrimsonLogic eCO | this page |
Preferential CO | Singapore Customs, under a free-trade agreement | TradeWeb / TradeNet |
If your customer's letter of credit or buyer asks for a certificate of origin, establish which one before you file. Filing the wrong instrument means starting again.
When the card appears
On any shipment loading in Singapore. A certificate of origin certifies where goods came from, so a shipment that merely discharges in Singapore never needs one.
What you can file
Type | Full name | What it certifies |
|---|---|---|
ECO | Ordinary Certificate of Origin | That the goods originate in Singapore |
ECP | Certificate of Processing | That the goods underwent qualifying processing in Singapore |
They are the same request with one field different; the form is identical.

Expect to type most of this one
A certificate of origin is mostly not freight data. The shipment answers about one field in ten — vessel and voyage, discharge port, consignee, the goods — and everything else is certificate and registration detail that only exists in your chamber paperwork.
That is not a gap in the integration. It is what the document is.
Your registration, entered once per company
Exporter UEN — and it must be registered with the chamber and contracted to your agent UEN. This is the one hard refusal: if it is missing or unregistered, no certificate is created at all.
Agent UEN and login
Signatory ID — the business email of the Agent Signatory registered with your chamber
Per certificate
AO code — which chamber endorses it. Your company is registered with specific chambers, and the form offers only those.

Consignee name, address and country

The signatory step
An eCO is not filed and forgotten. It is signed by a person your chamber has registered, and that signing happens in CrimsonLogic's own portal — not here.
You choose what should happen on submit:
Choice | What happens next |
|---|---|
Draft | The certificate is created and left as a draft. Nothing goes to the chamber. This is the default. |
Submit to signatory | Your registered Agent Signatory is asked to sign it, in the eCO portal. |
Submit to AO | It goes straight to the chamber. |
The default is Draft on purpose: nothing reaches a chamber unless you explicitly choose it.
While a certificate is waiting on a signatory, the record here says so — that is the cue to go and sign it in the portal.
The eCO submit choice — Draft, Submit to Signatory, or Submit to AO
What comes back
The chamber's decision arrives on the record:
The chamber says | You see |
|---|---|
Approved | Accepted, with the approval date |
Rejected | Rejected, with the chamber's reason |
Queried | Still awaiting — with the chamber's question shown on the record |
Returned | Still awaiting — the chamber has sent it back for amendment |
Cancelled or replaced | Cancelled / Superseded by newer submission |
A query is the one to watch for. The chamber is asking you something, the certificate is not rejected, and the question text appears on the record.
The record shows the chamber's own words rather than a status we invent, and it stays locked while the certificate is with them — a chamber decision can take days to weeks.
Amending and cancelling
Amend only while the certificate is still a draft. Once it has gone to a signatory or a chamber, it cannot be updated — cancel and file again.
An amendment replaces the item list wholesale rather than merging into it. Re-check your items after amending.
Cancel only within one month of the chamber approving it.
