What was the purpose of replacing the BC Code with the IMSBC Code?

(1) To make the Code mandatory (the BC Code being only recommendatory for implementation by States); to draw a parallel with the structure of the IMDG Code (e. g. the Code will be reviewed every 2 years like the IMDG Code); (3) to include references to the most recent SOLAS Amendments; and (4) to add new products and update information for existing cargoes.
