UK overseas trade in goods statistics February 2023: methodology notes

Published 13 April 2023

Metadata

Data behind this bulletin is available through the UK Trade Info web site:

• Detailed Trade Statistics data at 8-digit commodity code level is available in our interactive database.

• Aggregate OTS data is available in pre-prepared Excel tables.

Data Sources

From 31 December 2020, the free movement of people and goods and services between the UK and the European Union (EU) ended. This meant the way HMRC had been collecting trade in goods statistics was revised.

UK to EU exports

For goods moving from 1 January 2021, GB to EU export statistics have been compiled directly from customs export declarations made according to the requirements of the Taxation (Cross Border Trade) Act. Intrastat survey returns, however, continued to be collected for goods exported from Northern Ireland to the EU, under the terms of the Northern Ireland Protocol.

Both the GB to EU customs export declaration data and NI Intrastat export (dispatch) data were incorporated into the overall UK to EU export dataset.

As a result of the changes and differences outlined above, there was a break in the timeseries for published UK to EU export statistics from January 2021.

UK imports from EU

UK imports from EU statistics were not impacted by any change in 2021. The Intrastat survey continued to operate for all UK (GB and NI) imports (arrivals) from the EU, to mitigate the effects of staging customs controls, and to comply with the Northern Ireland Protocol.

However, from 1 January 2022, Intrastat only applied for movements of goods between Northern Ireland and the EU. Statistics on movements to GB from the EU have been compiled directly from customs import declarations. Both the EU to GB customs import declaration data and NI Intrastat import (arrivals) data were incorporated into the overall EU to UK import dataset.

As a result of the changes and differences outlined above, there was a break in the timeseries for published EU to UK import statistics from January 2022.

Northern Ireland Trade

Figures derived from Intrastat include the following:

• Estimates for businesses who have yet to submit detailed data on the trade they had with other EU Member States this month.

• Estimates for businesses who do not have to submit detailed data on the trade they have with other EU Member States.

Estimates are included in all high-level totals including commodity (HS2) and country totals.

Non-EU trade

Non-EU trade are compiled from customs declarations collected by the CHIEF (Customs Handling of Import and Export Freight) system. Declarations collected via the Customs Declarations Service (CDS) are included: for imports from August 2020 month of account; and for exports from December 2020 month of account onwards. Detailed trade inf ormation is presented according to the Harmonised System (HS) nomenclature.

Methodology

The Overseas Trade in Goods Statistics Methodology paper (July 2022) covers:

• data sources

• classifications and definitions

• quality assurance

• publications and

• governance.

It is a useful companion to the trade data, providing the definitions and methodologies on which the data are based. The most recent changes in the OTS methodology are covered in this paper.

Non-Monetary Gold (NMG) can form a substantial part of the non-EU Overseas Trade Statistics (OTS). For further information, see Inclusion of Non-Monetary Gold in OTS. Data relating to monthly non-EU and EU import and export totals for January 2008 onwards with a breakdown of non-monetary gold and other trade is available in an OTS time series spreadsheet.

Relationship with other statistical publications

The aggregate estimates here will differ slightly from those that are published by the Office for National Statistics (ONS) as part of the Balance of Payments (BoP), as the 2 sets of data are compiled to different sets of rules. The ONS website provides an overview of BoP, where you can find their detailed monthly UK Trade Releases. The BoP publication shows a high-level picture of UK trade-in-goods, whereas the OTS publication shows a detailed picture of the UK’s trade-in-goods by commodity and partner country.

National Statistics Publication

HM Revenue & Customs released these latest statistics on Overseas Trade with countries on 13 April 2023 under arrangements set out in the Code of Practice for Official Statistics.

This release includes the first provisional estimates of trade-in-goods between the UK and both countries of the EU and those outside the EU for February 2023. At the same time revisions for all previously published non-EU and EU data for 2022 are also being released in line with the HM Revenue & Customs Policy on Revisions.

The next three publications are due for release on the following days:

Month of Account	First release date
March 2023	12 May 2023
April 2023	14 June 2023
May 2023	13 July 2023

The OTS has been reviewed as part of an assessment made of Overseas Trade in Goods Statistics by the UK Statistics Authority.

The United Kingdom Statistics Authority has designated these statistics as National Statistics, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Official Statistics. Designation can be broadly interpreted to mean that the statistics:

• meet identified user needs;

• are well explained and readily accessible;

• are produced according to sound methods; and

• are managed impartially and objectively in the public interest.

Once statistics have been designated as National Statistics it is a statutory requirement that the Code of Practice shall continue to be observed.

Now that the UK has left the EU, it is important that our statistics continue to be of high quality and are internationally comparable. All releases continue to be produced in accordance with the UK Statistics Authority’s Code of Practice for Statistics as well as internationally agreed statistical guidance and standards.
