Regarding using 8000 not 9000 for customs clearance, when does this start? If the ACI Supplementary data was filed, do we need to file eManifest again to get the 8000?

If the ACI S10 Supplementary data was filed and the cargo loaded, the freight forwarder may process the Customs release against the primary carrier 9000 CCN.  Or the freight forwarder may file an eHBL data set and Close Message and then the Customs release request will be under that eHBL 8000 CCN. As of January 4, 2021, the eHBL data set and the Close Message must be filed within the timeframes or risk receiving a zero-rated AMPS NPA (Notice of Penalty Assessment). When an eHBL 8000 secondary data is filed, that eHBL 8000 CCN is used for the Customs release request.
