>>Refreshing UK/EU Tariff data, using data which has been copied from Production on Wednesday 15th July*

*Trader Dress Rehearsal is a sandbox environment and is regularly refreshed with Trader data and data from the Online Tariff on a given date, as such any CDS changes to Trader data in the live service or updates to the Online Tariff will not be reflected in TDR instantaneously.
