Cost recovery waiver eligibility requires meeting cargo volume and document throughput thresholds over preceding years to obtain exemption. Exemption from cost recovery charges for an AFS depends on meeting prescribed staffing norms and performance benchmarks: specified minimum annual cargo volume and minimum annual number of documents. Qualification requires satisfying both thresholds in the two preceding financial years or either threshold in any one of the preceding four financial years. Procedural rules on creation of cost recovery posts, payment, waiver grant or withdrawal, and de-notification set out in the Board's circular are applicable to AFS.
