HMRC were not able to deploy a new iteration of the CDS Tariff initial extract, daily and monthly files as intended in July.
This update introduces a significant update to the Tariff data, so HMRC recommend that you use the new initial extracts and subsequent download files when they come available.
The fix is now scheduled for the next planned CDS release in mid-September. However HMRC are hoping for an earlier deployment and will send out a further update should this be possible.
