The introduction of the New Export System (NES) is responsible for the large increase in electronic declarations for exports.

A DEP allows an approved operator (such as a consolidator, exporter, forwarder or airline) to present goods and submit declarations for export to HMRC from their Customs approved premises.

For more information on SDP and LCP, see the page on Supplementary Declarations for export purposes and the National Export System in our guide on using and submitting Supplementary Declarations.
