Singapore — TradeWeb
Singapore Customs declarations — import, export, transshipment and preferential certificates of origin — filed through CrimsonLogic TradeWeb to TradeNet, from inside the shipment.
Read Customs filing first for the flow. This page covers what is specific to Singapore.
When the card appears
On any shipment loading in Singapore or discharging in Singapore. Both directions — an export needs it as much as an import.
What you can file
Type | Full name | Direction | Use it for |
|---|---|---|---|
INP | Inward Non-Payment | Import | Goods entering Singapore with no duty or GST payable at declaration |
IPT | Inward Payment | Import | Goods entering Singapore with duty or GST payable |
OUT | Outward | Export | Goods leaving Singapore |
TNP | Transshipment | Transit | Cargo moving through Singapore to somewhere else |
COO | Certificate of Origin | Export | A preferential certificate of origin, issued through TradeNet |
COO here is the TradeNet preferential certificate. It is not the same document as a chamber-endorsed Ordinary Certificate of Origin — that is Singapore — eCO, a different instrument from a different issuer. If someone has asked you for a "CO" and you are not sure which, ask which body is meant to endorse it.

The Singapore TradeWeb card, with the declaration types that apply to an export
The form is your portal's form
The Singapore declaration is laid out the way TradeWeb lays it out — the same tabs, in the same order, under the same field names the portal prints:
Header · Party · Cargo · Out-Trans (or In-Trans on an import) · Ref. Documents · Invoice · Items · Summary
This is deliberate. You already know this form; you should not have to learn a second one to file the same declaration.

What you need to have ready
The shipment supplies roughly four in ten of the fields on a Singapore declaration. Singapore asks for a lot that a freight file does not carry, so expect to complete the rest yourself.
Always:
Sender ID and CR UEI No. — your company's TradeNet registration
TradeNet Mailbox ID (the declarant ID)
Declaring Agent UEN
Declaration type — the specific TradeNet code within the family (
DRT,GTR, and so on)Cargo pack type and transport mode
On an import (INP / IPT), additionally: consignee address, place of release, place of receipt, ETA, and — where duty applies — GST rate, GST amount and brand.
On an export (OUT), additionally: consignee address, place of receipt, ETD, exporter UEN.
On a certificate of origin (COO): HS code, country of origin, goods description, consignee name and exporter UEN.
Values that are the same across every house bill on the shipment — your own registration details, the vessel, the master bill — are entered once and carried across.
Items
Goods lines come from the shipment's commodities and every line is editable. You can add lines up to 50 items, which is TradeWeb's own limit.
Filing a draft first
Singapore is one of the countries where you can put a declaration in front of yourself before you put it in front of Customs.
Mode | What happens | Status |
|---|---|---|
Draft in TradeWeb | The declaration is saved in your own TradeWeb portal. Singapore Customs never sees it. Open it there and review it exactly as you would one you keyed yourself. | Draft on the TradeWeb portal — not filed to Customs |
File to Customs | A real permit application. | Awaiting customs response |
The submit button names which one you are doing. A draft is not an error and not a verdict — the record offers you Submit to Customs →, because there is nothing to correct.

The filing-mode choice — a reviewable draft in your own TradeWeb portal, or a real permit application
Worth knowing on your first few filings. A draft saved to your portal may show fields highlighted as required that our form did not ask you for. TradeWeb's own form asks for a few things we do not yet send — the inward and outward carrier agents, the claimant party on an import, and country of final destination. Complete those in the portal before you submit from there, and tell us: we are closing the gap.
What comes back
TradeWeb answers in two stages, and it matters that you know the difference.
A receipt. The gateway acknowledges that it has your message. This is not a decision.
A verdict. TradeNet processes the declaration and answers — accepted, or rejected with reasons.
The status on the record always reflects the second one. Rejections are decoded into plain English with the field to fix, and — for the HS-unit mismatch, the most common one — a one-click correction.
Each decoded reason also names who should act on it. Some are yours to correct on the form; some are ours to fix in how the declaration is built. When it says ours, send it to support rather than re-filing — a re-file will earn the same rejection.
Gotchas
Units of measure are three-letter TradeWeb codes —
CTN,PKG,BOX,KGM,TNE. If your shipment carries a two-letter code from another standard, the declaration converts it. You will see the TradeWeb code on the form; that is correct.An empty field is not the same as an absent one. Singapore's gateway treats a blank value as a present-but-incomplete element, and the resulting error often names a different field than the one actually at fault. If a rejection reads oddly, check the fields near the one it names.
Certificate of origin sits inside the export flow, not beside it — a
COOcan accompany anOUTon the same shipment.
