Definition & Explanation

Two independent systems capture the same shipment data at the same time – that is the core of parallel control. It involves the simultaneous, independent verification of identical data or process steps by two separate systems or reviewers, so any divergence in weight, tariff classification, or description surfaces before the consignment moves to the next stage. In customs and freight forwarding, the mechanism is commonly applied where the forwarder's logistics platform and the carrier's or authority's automated pre-notification system run side by side. Discrepancies trigger an alert rather than passing silently through the process. The approach is a recognised element of compliance frameworks for Authorised Economic Operators and differs from a follow-up check, which is sequential rather than concurrent.
