You may amend an approved permit via TradeNet if it is within the permit's validity period. There is no limit to the number of times a permit can be amended. Do note that not all fields are amendable. 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 to the sample of an amended Cargo Clearance Permit.
Please cancel the permit with the permit's validity period and apply for a new one if you have provided inaccurate details which cannot be amended. You are not allowed to use transhipment permits that have been cancelled to tranship goods.
You may have to cancel certain permits (e.g. transhipment permits with inter-gateway movement) or extend their validity periods if you do not use them. Please refer to the requirements stated in the permit conditions.
You are not allowed to cancel a transhipment permit if:
- It has been used for cargo clearance;
- It has expired for more than a calendar day; or
- It has been requested by the Manifest Compliance Unit of Singapore Customs for audit purposes.
For such cases, please submit a voluntary disclosure to Singapore Customs.
