1. The Primary Cargo Control Number is defined by the CBSA as the original cargo control number (CCN) used in the submission of the house bill to reference the carrier’s primary cargo document, with the carrier code preface – for example 9000 for ocean carriers or the master airway bill for air carriers. Truck and railroads also issue primary cargo control numbers.
   

1. The 9000 CCN is provided by the carrier but it is not always carrier 9000 code + B/L number. Each carrier has different variations and one must insist on a carrier providing the cargo control number in writing. Example – Hapag Lloyd B/L starts with HLCU (their SCAC code) but the HLCU part is not included in the CCN.
   

           Overseas agents or offices must receive the primary CCN from the carrier – usually at time of booking.

1. Co-Loaders will have primary carrier CCN on hand and must provide it to each freight forwarder they are providing space to in ocean container or airline unit.  Every tier of forwarder requires the primary carrier’s cargo control number on the eHBL transmission.
   However, the Housebill Close message is always filed ‘up’ to the previous CCN, not to the primary CCN.
