[]
["The Customs Importer and Exporter Population reports counts of unique Economic Operators Registration and Identification (EORI) numbers per partner (EU / non-EU) and direction (import / export). Businesses and individuals wishing to trade must use the EORI number as an identification number in all customs procedures when exchanging information with customs administrations."]

["The unique count for the Customs Importer and Exporter Population is produced from customs declarations data for movements of goods between GB and the EU and between the UK and non-EU countries. Customs declarations are not required for movements between Northern Ireland (NI) and the EU, therefore are excluded from this publication as they are not part of the customs process. "]

["Further notes:"]
["Users should be aware that this publication supersedes the UK Importer and Exporter Population publication. The Customs Importer and Exporter Population reports only on 2021 and draws no comparison to data on previous years. HMRC encourages users to apply caution if making comparisons to the UK Importer and Exporter Population. Please see Changes to publication below for details."]
[]
["Changes to publication:"]
["Previous Publications: HM Revenue & Customs (HMRC) published the UK Importer and Exporter Population publication for each calendar year from 2016 to 2020, providing an annual count of importing and exporting businesses trading with European Union member states and with non-EU countries. "]
["Summary of Changes: On 1 January 2021, the UK officially left the European Customs Union; this led to changes in the way HMRC collects statistical data. It follows that a methodology change was needed to accurately represent the trade in goods population post 2021, this included changes to:  \n•\tData sources \n•\tDefinition of a Trader\n•\tGeographic area covered\n•\tInclusion of non-VAT registered traders trading with the EU and Low Value traders\nThis means the figures contained in the release will not be comparable to those in previous releases."]
["Detailed Changes:"]
["a. Data sources \nThe source data for the Customs Importer and Exporter Population is the customs declarations data submitted to CHIEF (Customs Handling of Import and Export Freight) and CDS (Customs Declaration Service). The publication therefore reports on the number of traders engaging with the customs process. \nA change in data source was necessitated due to core methodology changes in how HMRC collects the trade in goods statistics since leaving the EU in January 2021.\nPreviously, the UK Importer and Exporter Population used the published Overseas Trade Statistics (OTS) as its source. This was presented on a special trade basis which excludes movements entering Customs warehouses and free zones / freeports. "]
["b. Definition of a Trader\nThe Customs Importer and Exporter Population defines a trader as a business or individual using an Economic Operators Registration and Identification (EORI) number to engage with customs procedures in the movement of goods between Great Britain (GB) and the European Union (EU), or between the United Kingdom (UK) and non-EU countries in 2021.\nPreviously, the UK Importer and Exporter Population counted unique VAT numbers per trade flow and trade partner, as the primary means of collecting data on trade between the UK and the EU before January 2021. Trade with non-EU was aggregated to the VAT level as part of the OTS methodology to ensure all UK trade was reported on a consistent basis. As it is possible for multiple EORI numbers to share the same overarching VAT number; counts in the new Customs Importer and Exporter Population are therefore more granular than those seen in previous publications. A consequence of this one-to-many relationship between VRN and EORI is that the count of individual traders may be subject to an increase. "]
["c. Geographic area covered\nThe unique count for the Customs Importer and Exporter Population is produced from customs declarations data for movements of goods between Great Britain (GB) and the European Union (EU) and between the UK (United Kingdom) and non-EU countries. \nCustoms declarations are not required for movements between Northern Ireland (NI) and the EU, therefore are excluded from this publication as they are not part of the customs process. \nPreviously, the unique trader count for the UK Importer and Exporter Population was produced from both Intrastat and VAT data for movements of goods between the UK and the EU, and customs data for movements of goods between the UK and non-EU countries. \nThe geographical areas are different between the data pre 2021 and post 2021, so comparisons of these populations should not be undertaken. "]
["d. Inclusion of non-VAT registered businesses trading with the EU\nSince January 2021, GB movements to and from the EU have been reported using customs declarations, which are required for all traders regardless of VAT registration status. The Customs Importer and Exporter Population therefore contains non-VAT registered traders moving goods between GB and EU, alongside traders moving goods between the UK and non-EU countries. \nFor trade in goods data before 2021, the UK Importer and Exporter publication was unable to include non-VAT registered businesses trading with the EU as these businesses were not required to submit this information to HMRC. "]
["e. Inclusion of non-EU business trading exclusively below the Low Value Thresholds\nFor trade in goods data before 2021, the UK Importer and Exporter used the OTS as its data source. A limitation of this data was that all items of trade with both a weight and value less then the annual low value thresholds set, were rolled up into one aggregated group. As a result, traders who only moved goods of this nature were not counted. \nThe changes to the source data used in the Customs Importer and Exporter Population have removed this limitation. Using customs declarations data allows for sight of traders moving goods between the UK and non-EU countries who trade exclusively within this low value group, before any aggregation has been carried out.
