Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

3.1. Data description
International trade in goods statistics (ITGS) measure the value and quantity of goods traded with the rest of the world. ‘Goods’ means all movable property including electricity. ITGS published by Eurostat are compiled on the basis of the concepts and definitions set out in EU legislation.
Trade by invoicing currency (TIC) data are part of the information available. The invoicing currency is the currency in which the commercial invoice is drawn up. These statistics are very useful to central banks, including the European Central Bank, for comparing the euro with other major international currencies. These data are also used by financial market segments or foreign investors.
Statistical dimensions available for TIC data:
reporting country;
reference period;
trade flows;
product; and
currency.
3.2. Classification system
Product classification
The Standard International Trade Classification (SITC) is managed by the United Nations and correlated with the subheadings of the Harmonised System. SITC Rev. 4 comprises 2 970 basing headings which are aggregated into 262 groups, 67 divisions and 10 sections. TIC data are based on the section level complemented by the division 33 ‘oil´.
Country classification
The ‘Nomenclature of countries and territories for the external trade statistics of the Union and statistics of trade between Member States’, known as the ‘Geonomenclature’, is used to collect detailed statistics on exchanges of goods. TIC data are only disseminated at an aggregated partner level: partner ‘extra-EU’ for TIC data reported by the EU Member States and partner ‘world’ for the TIC data reported by the EFTA and enlargement countries. See the publication Geonomenclature applicable to European statistics on international trade in goods for more information (European business statistics geonomenclature applicable to European statistics on international trade in goods - 2023 edition - Products Manuals and Guidelines - Eurostat (europa.eu).
3.3. Coverage - sector
The scope of TIC data is the same as for monthly detailed data on trade in goods. They cover all goods entering (imports) or leaving (exports) the statistical territory. Note that the statistical territory of in addition to the customs zone also includes the Norwegian part of the continental shelf - where the oil and gas infrastructure in addition to fishing is located. As ITGS in general, TIC data cover all industries of the economy.
3.4. Statistical concepts and definitions
Reporting country – Except for some specific goods like vessels and aircraft, ITGS follow the physical movements of the goods. A country should record an import when goods enter its statistical territory and an export when goods leave that territory except if those goods are in simple transit.
Partner country – At detailed level, this is the last known country of destination for exports and the country of origin for imports. However individual partner countries are not kept in the dissemination of data by invoicing currency. They are replaced by the partner area ‘World’.
Product – Goods are primarily classified by commodity code as set out in the EU Combined Nomenclature. TIC data are compiled on the basis of a correspondence table enabling the transposition of detailed data collected according to the Combined Nomenclature into the Standard International Trade Classification (SITC).
Since 2022 Norwegian TIC data are available for the ten individual SITC sections 0-9. In addition SITC section 33 (oil) is available separately.
Before 2022 TIC data are available by three product groups: Raw materials without oil (SITC sections 0-4, excluding division 33), Oil (SITC division 33) and Manufactured products (SITC sections 5-8).
Currency – The invoicing currency is the currency in which the commercial invoice is drawn up. Its definition is provided by the customs legislation. Only the following currencies or groups of invoicing currencies are considered for data transmission to Eurostat:
Common currencies that are reported:
Euro (‘EUR’);
Norwegian krone (‘NOK’);
UK pound sterling (‘GBP’);
US dollar (‘USD’);
National currencies of non-euro area Member States (‘XU3’);
Other not specified currencies (‘_X’);
Unknown currency (‘_U’);
Total ‘_T’.
Mandatory invoicing currencies provided:
Canadian dollar (‘CAD’);
Swiss franc (‘CHF’);
Chinese yuan renminbi (‘CNY’);
Indian rupee (‘INR’);
Japanese yen (‘JPY’);
Russian rouble (‘RUB’);
Singapore dollar (‘SGD’);
Turkish lira (‘TRY’).
Albanian lek (‘ALL’);
Bosnia-Herzegovinian convertible mark(‘BAM’);
Bulgarian lev (‘BGN’);
Brazilian real (‘BRL’);
Czech koruna (‘CZK ’);
Danish krone (‘DKK’);
Georgian lari (‘GEL’);
Hungarian forint (‘HUF’);
Icelandic krona (‘ISK’);
Macedonian denar (‘MKD’);
Mexican Peso (‘MXN’);
Moldovan leu (‘MDL’);
Polish zloty (‘PLN’);
Romanian leu (‘RON’);
Serbian dinar (‘RSD’);
Swedish krona (‘SEK’);
South Korean Won (‘KRW’);
Ukraine hryvnia (‘UAH’).
Note on use of Norwegian krone for imports: In the cases where multiple invoice currencies are used on the same declaration, NOK is chosen as the default currency by Norwegian customs. This leads to the value of the Norwegian krone being larger than it should actually be.
The set of collected currencies has been evolving over time. Initially, only 5 currencies were collected (EUR, USD, _X, XU3 and _T). Since 2020 reference year, _U currency was added. The full set mentioned above has been collected only since 2022 reference year.
3.5. Statistical unit
The statistical unit is any natural and legal person lodging a customs declaration in Norway on the condition that the customs procedure is of statistical relevance.
3.6. Statistical population
The statistical population comprise all the legal or natural persons who shipped goods to or from Norwegian economical territory.
3.7. Reference area
TIC data are available for the European Union and the euro area as aggregates as well as for all the EU Member States individually. They are also available for the following non-EU countries:
All EFTA countries except Liechtenstein for which a derogation applies: Iceland, Norway and Switzerland;
United Kingdom (until 2018 reference year);
Northern Ireland (since 2022 reference year); and
Enlargement countries (candidate countries and potential candidates): Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia, Serbia and Turkey.
3.8. Coverage - Time
TIC data disseminated by Eurostat
TIC data must be compiled once every two years starting with 2010 as reference year (2014 for Croatia and 2012 for EFTA countries). Data relating to in-between years are optional, which leads to incomplete geographical coverage. 2017 is the first in-between year for which optional TIC data are available. Note that Liechtenstein is exempted from providing TIC data.
See document TIC Quality indicators for more informatin on time periods covered by the data.
3.9. Base period
Not applicable.
For data transmission to Eurostat – Trade values (in national currency units) by invoicing currency. The value of traded goods is calculated at the national frontier, on a FOB (free on board) basis for exports and a CIF (cost, insurance, freight) basis for imports. Hence, only incidental expenses (freight, insurance) are included and they are incurred for:
exports in the part of the journey located on the territory of the country where the goods are exported from;
imports in the part of the journey located outside the territory of the country where the goods are imported to.
For data dissemination on Eurostat website – Share of each invoicing currency in extra-EU imports and exports for EU Member States and Northern Ireland, or in world imports and exports for EFTA and enlargement countries.
Theoretically, the reference period for the information on international trade in goods transactions should be the calendar month of export or import of the goods. However, in practice the reference period is generally the calendar month during which the customs declaration is accepted by the National Customs Authority.
The reference years for which TIC data are disseminated result from the aggregation of monthly figures from January to December.
6.1. Institutional Mandate - legal acts and other agreements
General statistical legislation
Regulation (EC) No 223/2009 of the European Parliament and of the Council on European statistics
Implementing Regulation (EU) 2021/1225 specifying the arrangements for the data exchanges and amending Implementing Regulation (EU) 2020/1197, as regards the Member State of extra-Union export and the obligations of reporting units;
Delegated Regulation (EU) 2021/1704 further specifying the details for the statistical information to be provided by tax and customs authorities and amending Annexes V and VI of Regulation (EU) 2019/2152.
Extra-EU trade legislation (or Extrastat) - legislation applicable up to 1 January 2022
Basic Act: Regulation (EC) No 471/2009 of the European Parliament and of the Council
Implementing Commission Regulation (EC) No 92/2010;
Implementing Commission Regulation (EC) No 113/2010.
All regulations relevant for the European statistics on international trade in goods can be found in the publication Legislation on European statistics on international trade in goods or consulted from the Legislation page of the International trade in goods section on Eurostat website. All legal texts of the EU are accessible on Eur-Lex.
6.2. Institutional Mandate - data sharing
Not applicable.
7.1. Confidentiality - policy
The regulation regarding confidentiality for ITGS is described in regulation (EU) No 2019/2152. Data by invoicing currency are for the most part not detailed enough that specific traders can be identified and are therefore free for publication. More detailed product categories and individual invoicing currencies though might make it possible to identify individual traders. In such a case release of confidential data will be protected by appropriate marking.
7.2. Confidentiality - data treatment
Data by invoicing currency are not detailed enough to make it possible to identify a specific trader. Therefore no specific data treatment applies.
8.1. Release calendar
No release calendar as such but the practice to publish TIC data at country level once they have passed all the quality checks. If all the validation rules are met, this means within a few days after the data transmission by the reporting country to Eurostat. Note that this practice applies both for a new reference year and for revisions.
In line with the EU legal framework and the European Statistics Code of Practice Eurostat disseminates European statistics on Eurostat's website (see item 10 'Accessibility and clarity') respecting professional independence and in an objective, professional and transparent manner in which all users are treated equitably. The detailed arrangements are governed by the Eurostat protocol on impartial access to Eurostat data for users.
TIC data are updated every year in April/May with a new reference year. However it should be noted that only TIC data relating to even years (e.g. 2020, 2022) are to be mandatorily provided to Eurostat. The geographical coverage might thus be incomplete for reference periods corresponding to odd years (e.g. 2021).
Revisions of historical data may occur at any time but remain exceptional.

10.6. Documentation on methodology
User Guide on European statistics on international trade in goods – The purpose of this Guide is to explain to a wide range of users how the statistics relating to trade in goods, both between EU Member States and with non-EU countries, are collected, compiled, processed and published at European level. The different issues are tackled in a question and answer format.
Quality Report on European statistics on international trade in goods — This Report provides users with a tool to assess the quality of the international trade in goods statistics published by Eurostat. The data quality can be assessed against indicators covering the following components: relevance, accuracy, timeliness and punctuality, accessibility and clarity, comparability and coherence.
11.1. Quality assurance
Quality reporting and assessment
The Extrastat regulation includes standardised quality articles. These articles are in line with the ESS Quality definition, European Statistics Code of Practice and the Regulation of European Statistics. In particular, they require the reporting countries to provide Eurostat with annual quality reports within a fixed deadline. Those reports are used for quality and compliance assessments. The following indicators are compiled for each reference year:
Statistical information required by the legislation but not or partially provided
Timeliness and punctuality of TIC data
Data quality checks prior to any dissemination
The prime responsibility for ensuring the data completeness and accuracy rests with the National Statistical Authorities. Further checks are carried out by Eurostat, essentially to ensure that the transmission of the requested data meets the requirements. Datasets must be complete, error-free, and all possible extreme values (outliers) confirmed.
11.2. Quality management - assessment
TIC data are derived from monthly detailed trade in goods data combined with additional information on invoicing currencies. Therefore their quality primarily depends on the quality of these two data sources.
12.1. Relevance - User Needs
TIC data are only disseminated by Eurostat. See item 12.1 ‘Relevance - User Needs’ of the related metadata ‘ext_tic - International trade in goods – trade by invoicing currency’ for more details.
12.2. Relevance - User Satisfaction
TIC data are only disseminated by Eurostat. See item 12.2 ‘Relevance - User Satisfaction’ of the related metadata ‘ext_tic - International trade in goods – trade by invoicing currency’ for more details.
12.3. Completeness
See item 12.3 ‘Completeness’ of the related metadata ‘ext_tic - International trade in goods – trade by invoicing currency’ for more details.
The accuracy is tackled at national and European levels, by eliminating as much as possible of the non-sampling errors. It should be noted that the accuracy of TIC data depends mainly on the accuracy of customs declarations.
13.2. Sampling error
Not applicable for most reporting countries as TIC data are generally entirely derived from information collected via customs declarations.
13.2.1. Sampling error - indicators
Not available.
13.3. Non-sampling error
See item 13.3 ‘Non-sampling error' of the related metadata ‘ext_tic - International trade in goods – trade by invoicing currency’ for more details.
13.3.1. Coverage error
Not applicable.
13.3.1.1. Over-coverage - rate
Not applicable.
13.3.1.2. Common units - proportion
Not applicable.
13.3.2. Measurement error
Not applicable.
13.3.3. Non response error
Not applicable.
13.3.3.1. Unit non-response - rate
Not applicable.
13.3.3.2. Item non-response - rate
Not applicable.
13.3.4. Processing error
Not applicable.
13.3.5. Model assumption error
For imports multiple currencies can be used on a single customs declaration. In these cases the currency is regarded as being in NOK. This leads to an overrepresentation of NOK for imports.
From a methodological point of view, the comparability across countries is ensured by the implementation of the concepts and definitions set up by the EU legislation and by the application of the complementary guidelines provided by the European business statistics compilers' manual for international trade in goods.
15.1.1. Asymmetry for mirror flow statistics - coefficient
Not applicable.
15.2. Comparability - over time
Changes due to definitions, classifications, coverage or methods will have an impact on the continuity of the time series. The most significant change came with the recent Regulation (EU) 2019/2152 on European business statistics.
With Regulation (EU) 2019/2152 the reporting of TIC data became more detailed from 2022 and onward. Both more currencies and more detailed product codes were reported.
From 2020 the _U (unknown currency) code for currency were included.
15.2.1. Length of comparable time series
Changes due to definitions, classifications, coverage or methods will have an impact on the continuity of the time series. The most significant change came with the recent Regulation (EU) 2019/2152 on European business statistics.
15.3. Coherence - cross domain
Apart from the TIC dataset, information on trade flows can be found in the aggregated and detailed trade in goods statistics. The intra-domain checks carried out by Eurostat before any data dissemination ensure the coherence between the trade values published in the TIC dataset and trade values coming from aggregated and detailed trade in goods statistics.
15.3.1. Coherence - sub annual and annual statistics
Not applicable.
15.3.2. Coherence - National Accounts
Not applicable.
15.4. Coherence - internal
The internal coherence of the TIC dataset is ensured by the intra-dataset checks carried out at national and European levels before any data dissemination. See item 18.4 ‘Data validation’ for more details.
TIC data are mainly derived from information collected via customs declarations, which means that the burden is low for the respondents, i.e. for the traders and businesses. Data on oil, gas and ships are collected from producers and shipping or shipping companies and therefore infer some burden for these enterprises.
17.1. Data revision - policy
Norwegian TIC data are noe disseminated nationay and there are therefore no formal revision policy. Eurostat accepts any data revisions insofar as they comply with all validation rules.
17.2. Data revision - practice
Statistics by invoicing currency are only exceptionally revised by the reporting countries. European Union and euro area aggregates are revised whenever data have been revised at country level.
17.2.1. Data revision - average size
Not available.
18.1. Source data
TIC data are derived from the combination of two types of information via customs declarations for imports and exports:
Trade in goods transactions;and
The invoicing currency associated to these transactions.
In addition data for oil and natural gas are collected directly from the exporters. These data amount to a large part of Norwegian exports, and are usually exported directly from the Norwegian shelf.
In addition change of ownership of ships and rigs are surveyed from the shipping companies.
18.2. Frequency of data collection
Collection of trade in goods data: Daily via customs declarations
Oil and gas: Monthly directly from exporters
Ships and rigs: Quarterly via survey
18.3. Data collection
Collection of trade in goods data
Data on trade in goods are collected daily from customs. These data include all external trade which businesses or private individuals perform. These data also include invoice currency. The invoicing currency is the currency in which the commercial invoice is drawn up. It is mandatory information to be collected by the Customs National Authorities for imported goods. Data on invoice currency is available for both imports and exports.
18.4. Data validation
At national level invoice currency is not validated. The statistical value though is validated monthly.
TIC data disseminated by Eurostat have passed the following quality checks:
Consistency with the expected IT structural requirements: validity of format and codes, integrity of the file
Consistency within the dataset: completeness of the file, consistency with EDAMIS metadata, intra-record checks on values, inter-record consistency checks, consistency checks on derived values
Consistency with other datasets within the same domain and the same data source - size of revisions, variation over previous reference years
Consistency within the same domain and a different data source: check of the coherence between trade values published in the TIC dataset and trade values coming from aggregated and detailed trade in goods data.
18.5. Data compilation
At national level:
TIC data are calculated on the basis of the transmitted trade values and their associated invoicing currency.
At European level:
The share of each invoicing currency in the imports and exports of Norway is calculated on the basis of the transmitted trade values.
18.5.1. Imputation - rate
At national level:
Crude oil is consideres sold in US-dollars while natural gas is considered sold in Euro.
At European level:
No imputation is made by Eurostat. The reporting country is asked to provide revisions in the case Eurostat's data validation system detects inconsistent values.
18.6. Adjustment
Not applicable at European level.
18.6.1. Seasonal adjustment
Not applicable.
International trade in goods statistics (ITGS) measure the value and quantity of goods traded with the rest of the world. ‘Goods’ means all movable property including electricity. ITGS published by Eurostat are compiled on the basis of the concepts and definitions set out in EU legislation.
Trade by invoicing currency (TIC) data are part of the information available. The invoicing currency is the currency in which the commercial invoice is drawn up. These statistics are very useful to central banks, including the European Central Bank, for comparing the euro with other major international currencies. These data are also used by financial market segments or foreign investors.
Statistical dimensions available for TIC data:
reporting country;
reference period;
trade flows;
product; and
currency.
2 June 2025
Reporting country – Except for some specific goods like vessels and aircraft, ITGS follow the physical movements of the goods. A country should record an import when goods enter its statistical territory and an export when goods leave that territory except if those goods are in simple transit.
Partner country – At detailed level, this is the last known country of destination for exports and the country of origin for imports. However individual partner countries are not kept in the dissemination of data by invoicing currency. They are replaced by the partner area ‘World’.
Product – Goods are primarily classified by commodity code as set out in the EU Combined Nomenclature. TIC data are compiled on the basis of a correspondence table enabling the transposition of detailed data collected according to the Combined Nomenclature into the Standard International Trade Classification (SITC).
Since 2022 Norwegian TIC data are available for the ten individual SITC sections 0-9. In addition SITC section 33 (oil) is available separately.
Before 2022 TIC data are available by three product groups: Raw materials without oil (SITC sections 0-4, excluding division 33), Oil (SITC division 33) and Manufactured products (SITC sections 5-8).
Currency – The invoicing currency is the currency in which the commercial invoice is drawn up. Its definition is provided by the customs legislation. Only the following currencies or groups of invoicing currencies are considered for data transmission to Eurostat:
Common currencies that are reported:
Euro (‘EUR’);
Norwegian krone (‘NOK’);
UK pound sterling (‘GBP’);
US dollar (‘USD’);
National currencies of non-euro area Member States (‘XU3’);
Other not specified currencies (‘_X’);
Unknown currency (‘_U’);
Total ‘_T’.
Mandatory invoicing currencies provided:
Canadian dollar (‘CAD’);
Swiss franc (‘CHF’);
Chinese yuan renminbi (‘CNY’);
Indian rupee (‘INR’);
Japanese yen (‘JPY’);
Russian rouble (‘RUB’);
Singapore dollar (‘SGD’);
Turkish lira (‘TRY’).
Albanian lek (‘ALL’);
Bosnia-Herzegovinian convertible mark(‘BAM’);
Bulgarian lev (‘BGN’);
Brazilian real (‘BRL’);
Czech koruna (‘CZK ’);
Danish krone (‘DKK’);
Georgian lari (‘GEL’);
Hungarian forint (‘HUF’);
Icelandic krona (‘ISK’);
Macedonian denar (‘MKD’);
Mexican Peso (‘MXN’);
Moldovan leu (‘MDL’);
Polish zloty (‘PLN’);
Romanian leu (‘RON’);
Serbian dinar (‘RSD’);
Swedish krona (‘SEK’);
South Korean Won (‘KRW’);
Ukraine hryvnia (‘UAH’).
Note on use of Norwegian krone for imports: In the cases where multiple invoice currencies are used on the same declaration, NOK is chosen as the default currency by Norwegian customs. This leads to the value of the Norwegian krone being larger than it should actually be.
The set of collected currencies has been evolving over time. Initially, only 5 currencies were collected (EUR, USD, _X, XU3 and _T). Since 2020 reference year, _U currency was added. The full set mentioned above has been collected only since 2022 reference year.
The statistical unit is any natural and legal person lodging a customs declaration in Norway on the condition that the customs procedure is of statistical relevance.
The statistical population comprise all the legal or natural persons who shipped goods to or from Norwegian economical territory.
TIC data are available for the European Union and the euro area as aggregates as well as for all the EU Member States individually. They are also available for the following non-EU countries:
All EFTA countries except Liechtenstein for which a derogation applies: Iceland, Norway and Switzerland;
United Kingdom (until 2018 reference year);
Northern Ireland (since 2022 reference year); and
Enlargement countries (candidate countries and potential candidates): Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia, Serbia and Turkey.
Theoretically, the reference period for the information on international trade in goods transactions should be the calendar month of export or import of the goods. However, in practice the reference period is generally the calendar month during which the customs declaration is accepted by the National Customs Authority.
The reference years for which TIC data are disseminated result from the aggregation of monthly figures from January to December.
The accuracy is tackled at national and European levels, by eliminating as much as possible of the non-sampling errors. It should be noted that the accuracy of TIC data depends mainly on the accuracy of customs declarations.
For data transmission to Eurostat – Trade values (in national currency units) by invoicing currency. The value of traded goods is calculated at the national frontier, on a FOB (free on board) basis for exports and a CIF (cost, insurance, freight) basis for imports. Hence, only incidental expenses (freight, insurance) are included and they are incurred for:
exports in the part of the journey located on the territory of the country where the goods are exported from;
imports in the part of the journey located outside the territory of the country where the goods are imported to.
For data dissemination on Eurostat website – Share of each invoicing currency in extra-EU imports and exports for EU Member States and Northern Ireland, or in world imports and exports for EFTA and enlargement countries.
At national level:
TIC data are calculated on the basis of the transmitted trade values and their associated invoicing currency.
At European level:
The share of each invoicing currency in the imports and exports of Norway is calculated on the basis of the transmitted trade values.
TIC data are derived from the combination of two types of information via customs declarations for imports and exports:
Trade in goods transactions;and
The invoicing currency associated to these transactions.
In addition data for oil and natural gas are collected directly from the exporters. These data amount to a large part of Norwegian exports, and are usually exported directly from the Norwegian shelf.
In addition change of ownership of ships and rigs are surveyed from the shipping companies.
TIC data are updated every year in April/May with a new reference year. However it should be noted that only TIC data relating to even years (e.g. 2020, 2022) are to be mandatorily provided to Eurostat. The geographical coverage might thus be incomplete for reference periods corresponding to odd years (e.g. 2021).
Revisions of historical data may occur at any time but remain exceptional.
See concepts 14.1.1 and 14.1.2.
From a methodological point of view, the comparability across countries is ensured by the implementation of the concepts and definitions set up by the EU legislation and by the application of the complementary guidelines provided by the European business statistics compilers' manual for international trade in goods.
Changes due to definitions, classifications, coverage or methods will have an impact on the continuity of the time series. The most significant change came with the recent Regulation (EU) 2019/2152 on European business statistics.
