1. In Singapore, all declarations for movement of goods are submitted and processed electronically through an EDI system known as 'TradeNet®'. Only Singapore-registered companies may apply to declare permits through the TradeNet® System. For companies who do not have TradeNet®, please approach the TradeNet® Service Centre.
   
   
2. A TradeNet® declaration will be assigned a unique reference number. This number serves to identify a particular declaration. This reference number consists of 3 data elements, namely, the declaring company's CR number, the date of transmission (YYYY MM DD) and the declaration's serial number. It is normally assigned automatically by the trader's software system.
   
   
3. Approved Customs permits would be transmitted back to the trader who will print the permit i.e. the Cargo Clearance Permit (CCP) at his own premises for clearance of the goods.

Use of Letter of Undertaking in the event of a declared TradeNet® System Failure

In the event of a declared TradeNet® system failure, traders who are unable to obtain an approved TradeNet® permit will use a Letter of Undertaking (LOU) to clear the goods. The template of the LOU can be found here ( DOC 29kb ). [The LOU here is not applicable for Strategic Goods]. On the LOU, the trader undertakes to apply for a TradeNet® permit through the TradeNet® System for the goods within three days from the date that TradeNet® services are restored.
