If the overseas agent files both ACI and eManifest before a shipment sails from Taiwan, will that be an issue for shipment clearance in Canada?

There is no need to file double data or pay for two transmissions. Remember, the 8000 number used to file the ACI S10 Supplementary data is a shipment reference only and is not linked to the eHBL 8000 Cargo Control Number. If the eHBL data set and the Close Message are both filed, then that eHBL 8000 CCN will be used for the Customs release request. There is no need then for ACI filing.
