Following the publication of UK trade: April 2021 some errors were identified in the HM Revenue and Customs (HMRC) overseas trade data used to compile Office for National Statistics (ONS) UK trade statistics.
These errors were identified following routine HMRC quality assurance and checking procedures. The main error affecting overseas trade data involved goods exported on a temporary basis, such as works of art or jewellery for an exhibition, being erroneously included as trade since March 2019. Additionally, several areas were identified where businesses had submitted incorrect trade data on their original trade declarations from 2015 to 2019. More information on these corrections can be found in HMRC’s correction notice.
Revisions for the period January 2020 to February 2021 were published in UK trade: May 2021 on 9 July 2021, taking place outside of the usual national accounts revisions period in order to ensure ONS trade statistics reflected the most up-to-date position.
Revisions for pre-2020 will be incorporated in the annual Blue Book publication in October 2022. This article provides users with an indicative estimate of the likely scale and impact of these corrections on the ONS trade statistics before their publication in the August 2022 UK trade statistics, due to be published in October 2022. This is the earliest publication possible to apply these revisions according to the national accounts revisions period.
HMRC has incorporated these corrections in the September 2021 Overseas Trade in Goods Statistics (OTS) publication released on 11 November 2021.
Data in this article are in current prices and have not been seasonally adjusted, to remove the effects of inflation or seasonal fluctuations. Caution should be taken when interpreting these data and they should only be used as an indication of the likely impact of these corrections.
2. Exports: non-EU
The revisions to remove the inclusion of goods exported on a temporary basis, such as works of art or jewellery for an exhibition, only affect the 2019 data for exports to non-EU countries. Exports to the EU are not affected. The total downward revision of £7.6 billion represents a 4.0% decrease to the annual value, from £187.3 billion to £179.7 billion.
Figure 1 shows the indicative impact to the non-seasonally adjusted monthly series, with the largest monthly revision occurring in October 2019, a fall of £1.3 billion (7.3%).

Although there are no revisions to exports to the EU, a consequence of these revisions to exports to non-EU countries is that for May 2019 non-seasonally adjusted exports to the EU are now greater than exports to non-EU countries.
The revision to exports to non-EU countries was driven by a £6.1 billion fall to miscellaneous manufactures, with revisions to works of art, jewellery and clothing. There was also a £0.8 billion downward revision to material manufactures, led by mineral manufactures, and a £0.7 billion downward revision to machinery and transport equipment, with contributions from mechanical power generators (intermediate), aircraft and cars.
|Revision (%)||Current |
|896 Works of art||-4.8||-48.7%||9.9||5.1|
|66 Mineral manufactures||-0.7||-32.7%||2.1||1.4|

Under the classification of product by activity (CPA), the works of art revision is broken down into a £4.3 billion reduction in exports of paintings and sculptures, and a £0.5 billion reduction to antiques and collections.
The revisions mostly apply to the exports data from the United States, Switzerland and Hong Kong, with these three countries together accounting for a total downward revision of £5.9 billion.

4. Future developments
The revisions documented in this article provide an indicative view of the corrections to 2015 to 2019 in the HM Revenue and Customs (HMRC) overseas trade data used to compile Office for National Statistics (ONS) UK trade statistics.
These revisions are not currently incorporated into any trade datasets published by the ONS.
When these are incorporated into ONS statistics in October 2022, they will be alongside any revisions that may have occurred from other standard statistical processing, such as seasonal adjustment.Nôl i'r tabl cynnwys
