Provisional assessment of export shipping bills requires EDI recording of test-report outcomes and formal adjudication when variances arise. Provisional assessment registers must be maintained and reasons for provisionalisation recorded. If test reports match declared particulars, the Preventive Officer shall feed them into EDI. If test reports conflict, the AC/DC in-charge shall open a file for adjudication, record the adjudication outcome and file number in EDI with the test report, make necessary changes to classification, drawback rates or value, and forward the file to the appropriate section for further action before returning it to the CFS.
