Revised Customs Classification Codes require import DTRs to be transmitted using new codes to ensure consistent data processing. Field formations must transmit all import DTRs-EDI, non EDI and manual-using the revised 8 digit Customs Classification Codes adopted from 1 February 2003; reporting with both old and new codes will disrupt centralised data processing and prevent timely adoption of the new classification. Issue instructions to all formations, send an immediate compliance report to the Board, and acknowledge receipt.
