You may amend an approved permit via TradeNet if it is within the permit's validity period. While there is no limit to the number of times a permit can be amended, do note that not all fields can be amended. Please click here for the List of Non-Amendable Fields. Once the amendments have been made, the most updated approved copy of the permit must be produced to the checkpoint officers for verification at the time of cargo clearance, if required in the permit conditions. Please refer here for a sample of an amended Cargo Clearance Permit.
Please cancel the permit within the permit validity period and apply for a new permit if you have provided inaccurate details which cannot be amended.
Payment permits approved under the GF or G7 condition must be cancelled before 2359 hours for the cancellation to be processed on the same day. Otherwise, cancellations for payment permits approved under the GF or G7 condition that are submitted within the permit validity period will require 5 working days for processing. The same applies to payment permits approved under the G1 condition.
At times, you may have to cancel or extend the validity period of some permits if you do not utilise them (for e.g., the In-Non-Payment Permit for Approved Premises/Schemes). Please refer to the permit conditions stated on the permit.
You are not allowed to cancel a permit if:
- It has been utilised for cargo clearance;
- It has expired for more than a calendar day;
- It is an In-Payment permit with duty or tax amount being paid; or
- It has been requested by the Manifest Compliance Unit of Singapore Customs for audit purposes.
For such cases, you are requested to submit a voluntary disclosure to Singapore Customs.
