Permit Validity
The validity period of an export permit depends on the type of goods, the purpose of the export, and the place of release or receipt.
General Validity Periods
The table summarises the typical validity periods for export permits using the OUT message type.
Export permit (message type) | Validity Period* |
OUT | Approval date + 9 working days |
Approval date + 2 working days for dutiable goods released from Customs licensed premises | |
Approval date + 1 working day for movement of dutiable sea stores |
*Note: Refer to the validity period stated on your permit. If you cannot use the permit within the validity period, you should extend the validity period of the permit via TradeNet before it expires.
