Accredited official statistics

UK regional trade in goods statistics, second quarter, April to June 2024: explanatory notes

Published 12 September 2024

Introduction

HM Revenue & Customs (HMRC) is responsible for collecting the UK’s international trade in goods data, which are published as two Accredited official statistics series - the ‘Overseas trade in goods statistics (OTS)’ and the ‘Regional trade in goods statistics (RTS)’.

The Regional trade in goods statistics were independently reviewed by the Office for Statistics Regulation in October 2010 with publication of the report in February 2011, download the assessment of compliance report (PDF, 137KB). They comply with the standards of trustworthiness, quality and value in the Code of Practice for Statistics and should be labelled ‘accredited official statistics’. Accredited official statistics are called National Statistics in the Statistics and Registration Service Act 2007.

The RTS is published quarterly showing trade at summary product and country level, split by UK regions and devolved administrations.

Please note that trade in goods values are in current prices. Figures are not adjusted for inflation or global economic events, so please take caution when making comparisons with historic data.

The latest statistics on Regional trade in goods were released by HMRC under arrangements set out in the Code of Practice for Statistics. This release includes the first provisional estimates of trade in goods for the second quarter (April to June) of 2024, and revisions for previously published regional data concerning 2023 and the first quarter of 2024.

Aggregated tables are produced to allow time series analysis:

• Table 1 Value (£ millions) of exports (EU / non-EU) by region
• Table 2 Value (£ millions) of imports (EU / non-EU) by region
• Table 3 Count of exporters (EU / non-EU) by region for both whole number method and proportion method
• Table 4 Count of importers (EU / non-EU) by region for both whole number method and proportion method
• Table 5 Value (£ millions) of trade by SITC section and country group (separate tables for each region)

These tables are provided in a supporting statistical data set to this release.

Data source changes

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 collected trade in goods statistics was revised.

UK to EU exports

Up to 31 December 2020, UK to EU export statistics were collected via the Intrastat statistical survey, which required traders to declare the value and volume of commodities exported to EU Member States within the relevant month of physical goods movement.

For goods moving from 1 January 2021, GB to EU export statistics are compiled directly from customs export declarations made according to the requirements of the Taxation (Cross Border Trade) Act. The customs declaration requirements are more complex than the single monthly aggregated Intrastat return and can result in differences between dates of declaration and actual movement of the goods out of the country.

The OTS compilation methodology relies upon the acceptance date of the customs export declaration for its inclusion within the relevant month of account, rather than the declared physical movement date used from the Intrastat survey.

Intrastat survey returns continue to be collected for goods exported from Northern Ireland to the EU, under the terms of the Northern Ireland Protocol and latterly the Windsor Framework.

Both the GB to EU customs export declaration data and Northern Ireland Intrastat export (dispatch) data are incorporated into the overall UK to EU export dataset. As a result of the changes and differences outlined, there is a break in the time series for published UK to EU export statistics from January 2021. Users are advised to note this change when making comparisons to previous quarters/years.

UK imports from EU

For UK imports from the EU, the Intrastat survey continued to operate in 2021 for all UK (GB and NI) imports (arrivals) from the EU, to mitigate the effects of staged 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, under the terms of the Northern Ireland Protocol and latterly the Windsor Framework. Statistics on movements into GB from the EU have been compiled directly from customs import declarations.

Therefore, from January 2022, the UK’s goods imports from EU dataset incorporates two data sources: GB’s goods imports from EU data that is collected via customs declarations and NI’s goods imports from EU data, collected via Intrastat declarations.

As announced in the Borders Control Statement (UIN HLWS473) on 15 December 2021, the Government extended the current arrangements for moving goods from the island of Ireland to Great Britain.

These temporary arrangements enable Irish traders to continue relying on staged customs controls for the foreseeable future. While these measures are in place, import statistics for trade between GB and Ireland are reported as declared and may not reflect the period in which the goods have been traded.

Please note that customs import declarations of non-controlled goods imported into GB from Ireland can be deferred for up to 175 days. This may affect the accuracy of trade data for GB imports from Ireland and associated aggregations.

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

More information on the recent changes to trade in goods statistics can be found on the UK Trade Info website.

Statistical value threshold in customs declarations

Customs declarations with commodity line values that fall under the statistical value threshold of £873 (in value) and 1,000kg (in net mass) are aggregated into ‘low value aggregates’. We do not receive business, product, or partner country information on these movements. As a result, we cannot assign this trade to a UK region, therefore the value is assigned to the Unallocated-Unknown region. This applies to goods exports from GB to EU countries from 2021, and imports to GB from EU countries from 2022. This is consistent with the RTS methods used for trade with non-EU countries, which are also sourced from customs declarations. As a result of this change, a value increase will be apparent for Unallocated-Unknown for EU flows from the dates specified.

Re-introduction of EU business counts

Due to the recent changes to data sources outlined, as well as changes to the VAT data source, a new method for EU business counts was introduced in the first quarter 2022 publication, which resulted in a break in series from previous RTS EU business counts. EU and total business counts from the 2021 data period onwards are therefore not comparable with RTS business counts published prior to 2021.

Prior to 2021, EU business counts were compiled from Intrastat declarations, while businesses trading below the Intrastat threshold were captured through VAT data. Businesses trading below the Intrastat threshold made up a small percentage of the total trade value but accounted for most of the businesses trading.

From January 2021, changes were made to the VAT data which means that only movements between Northern Ireland and EU countries are accurately recorded. Further, following EU Exit, trade between GB and EU countries is now reported through customs declarations rather than Intrastat. Customs declarations therefore became the main data source for GB exports to EU countries from January 2021, and GB imports from EU countries from January 2022.

As a result of the changes outlined, a new time series for EU business counts begins from the data period of the first quarter (January to March) 2021. EU business counts are now compiled in this way:

EU exporters from 2021 onwards:

• GB exports to EU countries via customs export declarations
• NI exports to EU countries via Intrastat (above threshold) and VAT data (below threshold)

EU importers for 2021:

• UK imports from EU countries were collected via Intrastat
• NI imports from EU countries for those below the Intrastat threshold collected via VAT data
• additional raw customs import declaration data to better capture the GB imports from EU countries
• throughout 2021, businesses could defer their EU imports declarations for up to 175 days, this may impact data quality

EU importers from 2022 onwards:

• GB imports from EU countries via customs import declarations
• NI imports from EU countries via Intrastat (above threshold) and VAT data (below threshold)

Overseas trade in goods statistics

Data is taken primarily from customs systems (for UK imports from and exports to non-EU countries and GB imports from and exports to EU countries) and the Intrastat survey (for Northern Ireland imports from and exports to EU countries). HMRC does not receive information in respect of goods that move wholly within the UK, nor in intangibles and services such as banking or tourism.

The Overseas trade in goods statistics (OTS) were published on a Special Trade basis from May 2016 account onwards. This change has been reflected in the RTS from the second quarter 2016 release onwards. All data in this release has been compiled on a special trade basis to allow comparisons across periods to be made. More information on general and special trade systems can be found in the OTS and RTS methodologies.

Updates to 2024 trade figures as published in the July 2024 OTS released on 11 September 2024 have not been applied to this second quarter 2024 (April to June) RTS release due to production lead in times.

Trade in non-monetary gold (NMG) is now included in OTS data, however this trade will continue to be excluded from RTS data. This is because the majority of NMG trade would be assigned to the London region and this would distort the RTS figures. The following reconciliation table (Table A) shows the differences at total trade level between OTS and RTS by quantifying the elements of OTS that are excluded from RTS.

Table A: RTS/OTS reconciliation table second quarter, April to June 2024 (figures in £ millions)

	EU Exports	Non-EU Exports	EU Imports	Non-EU Imports
OTS total value	44,188.6	51,352.1	81,504.9	78,199.6
RTS total value	43,802.8	44,007.7	79,484.9	67,901.2
Late response estimates	36.6	0	31.0	0
Non-monetary gold	349.2	7,344.4	1,989.0	10,298.4
RTS total plus exclusions	44,188.6	51,352.1	81,504.9	78,199.6

Please note:

• there may be rounding differences between the total shown and the sum of its components
• late response estimates only concern trade between Northern Ireland and EU countries, and are excluded from RTS trade
• non-monetary gold is excluded from RTS trade
• 2024 data is provisional and subject to update

Balance of Payments

The Balance of Payments (BoP) figures published by the Office for National Statistics (ONS) are calculated on a different basis to the OTS. Therefore, adjustments are made when producing BoP which means that the RTS and BoP are not comparable. The ONS website provides an overview of BoP, and is where you can find their detailed monthly UK trade releases.

Methodology

Following an informal public consultation on Regional trade in goods statistics (RTS), releases from the third quarter 2016 release incorporates changes to the methodology and presentation that resulted from this consultation. The main changes were:

• allocating a business’ trade to a region based on their proportion of employees in that region rather than where the location of the Head Office of the business is
• dividing trade that cannot be allocated to a region into ‘Known’ and ‘Unknown’
• for specific energy goods, using data received by HMRC direct from interconnector and rig operators rather than the business doing the trade
• the number of businesses now includes all VAT registered traders rather than just those who are required to make full declarations to HMRC for their EU trade

Please see the re-introduction of EU business counts section for changes to business counts from the first quarter (January to March) 2022 release onwards.

RTS data is compiled by merging trade data collected by HMRC with employment data from the Interdepartmental Business Register (IDBR). A business’ trade is allocated to a region based on the proportion of its employees employed in that region. Where a trader is not matched with the IDBR, its trade is matched with ONS postcode data to obtain the region in which the Head Office of the VAT registered business (importer or exporter) is based.

Not all trade can be assigned to one of the 9 English Regions, Wales, Scotland and Northern Ireland. Where appropriate, this is referred to in the tables as the ‘Unallocated Trade’. Unallocated Trade is split into:

‘Unallocated – Known’: where we have virtually full details of the trade, but it is not appropriate to allocate it to a region. This includes:

• trade going into or out of the Channel Islands or the Isle of Man
• trade carried out by overseas based traders who have a VAT presence in the UK
• trade carried out by the UK Government
• parcel post trade that is dealt with centrally (trade collected via customs declarations)

‘Unallocated – Unknown’: This includes:

• trade where business details submitted are invalid
• un-registered businesses (trade collected via customs declarations)
• private individuals (trade collected via customs declarations)
• low value trade (trade collected via customs declarations)

For specific energy goods only, trade is allocated to the region where the goods enter or leave the UK rather than the location / employment of the business doing the trade. This is because HMRC receives details of the trade in these goods directly from grid operators rather than the business. The goods concerned are Electrical energy, Natural Gas in a gaseous state and Crude Oil exported directly from offshore oil rigs. Crude Oil imported to the UK and exported from terminals is still allocated to the region of the business.

The business count is derived from trade declarations and is a count of businesses importing and exporting. Please see the re-introduction of EU business counts section for changes to EU business counts from the first quarter (January to March) 2022 publication onwards.

Where businesses have branches in multiple regions, there are two ways of deriving the count:

Whole number method: A business will be counted as one in every region they have employees. This represents the actual count of businesses in any region. However, it will mean the sum of the trader count for each region will be greater than that for the UK.

Proportion method: A business will be counted as a fraction in each region they trade based on the proportion of their employees in each region. An individual business counts as one business in the UK. The sum of businesses (whole and fractions) gives the total business count for a region.

We show results from both methods in the table 3 of the accompanying data tables

RTS data is categorised by partner country and Standard International Trade Classification, Rev.4. (SITC) at division level (2-digit). The SITC is a relatively broad classification of goods and is not as detailed as the commodity classification available in the OTS. In this release RTS data is analysed at partner country and SITC section (1-digit) level, with references to SITC divisions where appropriate.

More information can be found in the RTS methodology document.

Related statistics

Northern Ireland Statistics and Research Agency (NISRA) publish the Northern Ireland Economic Trade Statistics (NIETS). NIETS data is gathered through the NI Annual Business Inquiry (ABI). Due to methodological differences, the NIETS and the RTS are not directly comparable.

On 10 April 2024, HMRC released the Customs Importer and Exporter Population statistics. It reports on the number of importers and exporters in the calendar year 2023, who were named on a customs declaration to move goods between Great Britain (GB) and the European Union (EU), or United Kingdom (UK) and non-EU countries. These counts will differ to RTS business counts. There are several differences between the two publications, namely that RTS includes data from Intrastat and VAT (for NI only) and excludes counts of traders that consistently fall under the commodity line threshold outlined.

The ONS produces the “International trade in UK nations, regions and cities” release which estimates the value of exports and imports of goods and services from 2016 to 2021 for subnational areas of the UK. The ONS release is produced on a BoP basis while RTS are compiled on an International Merchandise Trade Statistics (IMTS) basis. There are numerous different methodologies that contribute to the compilation of each set of statistics, a key difference being RTS is compiled based on goods physically entering or leaving the UK, while the ONS subnational trade is produced on a change of economic ownership basis.

Governance

The United Kingdom Statistics Authority has designated these statistics as Accredited official statistics, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Statistics. Accreditation 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
• are managed impartially and objectively in the public interest

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

Our statistical practice is regulated by the Office for Statistics Regulation (OSR).

OSR sets the standards of trustworthiness, quality and value in the Code of Practice for Statistics that all producers of official statistics should adhere to.

You are welcome to contact us directly with any comments about how we meet these standards by emailing uktradeinfo@hmrc.gov.uk.

Alternatively, you can contact OSR by emailing regulation@statistics.gov.uk or via the OSR website.

The Regional trade in goods figures undergo regular quality assurance reviews to ensure they meet customer needs. These reviews are published as a Government Statistical Service Quality report.

There is a limited service to provide RTS outputs directly from HMRC trade statistics where the data cannot be obtained from other sources. This service is subject to HMRC standard disclosure rules applied to previously unpublished data.

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.
