Siscomex maintains an activation schedule for import operations that still require adjustments in the Single Window. Implementation is phased according to the consenting agencies and the characteristics of each operation.
The official page also presents risk management during Duimp pre-registration, intended to guide importers on requirements and possible inconsistencies before registering the declaration.
As the schedule may be updated, the official source should be checked for each shipment. This article reflects information consulted in October 2026 and does not replace verification of the treatment applicable to the goods.
