Track and Trace requirement: barcoded tertiary and secondary packaging plus portal data upload required for eligible pharmaceutical exports. Implementation of a Track and Trace system requires exporters to upload prescribed packaging relationship and barcode data to the Central Portal; drugs manufactured before the transitional cut-off are exempt from three-level Parent-Child packaging data upload, while drugs manufactured after the cut-off may be exported only if tertiary and secondary packaging carry barcoding and the prescribed data is uploaded.
