Duty drawback rate update must be reflected in EDI systems to prevent incorrect claim settlements and supplementary filings. Revision of the duty drawback rates and certain Drawback Schedule entries requires immediate incorporation into the EDI System directories; some field units are still clearing claims at old rates, causing exporters to file supplementary claims. Field formations are instructed to update EDI immediately and to maintain timely updates for any future Drawback Table changes to prevent incorrect settlements and delays.
