The main objective of the trade in goods statistics by enterprise characteristics (TEC) is to bridge two major statistical domains which have traditionally been compiled and used separately, business statistics and international trade in goods statistics (ITGS). Specifically, this new domain was created to answer questions such as:

• What kind of businesses are behind the trade flows of goods?
• What is the contribution of a particular activity sector to trade?
• What is the share of small and medium-sized enterprises to total trade?
• What is the share of enterprises that trade with a certain partner country and the amount of trade value they account for?

For this purpose, the trade in goods between countries is broken down by economic activity, size-class of enterprises, trade concentration, geographical diversification and products traded. The new information is used to carry out more sophisticated kinds of analysis, e.g. to evaluate the role of European companies in the context of globalisation or to assess the impact of international trade in goods on employment, production and value added, essential in a globalised world where economies are increasingly interconnected.

Available datasets

TEC data are grouped into ten datasets, each one focusing on a specific aspect:

1. Trade by activity sector and enterprise size class — Trade by activity sector and employment size class shows the contributions of economic activities and size classes (measured in terms of number of employees) to total trade. This allows the impact of international trade on employment to be analysed and the importance of small and medium-size enterprises (SMEs) to be estimated.

2. Concentration of trade by activity — International trade being typically dominated by a few businesses, this indicator shows the share of the total trade accounted for by the top 5, 10, 20, etc. companies.

3. Trade by partner country and activity — Trade by partner country shows how many companies were trading with certain partner countries or country zones, and the value they accounted for. This indicator enables the most typical export or import markets to be identified.

4. Trade by number of partner countries and activity — Trade by number of partner countries shows how geographically diversified the export markets are. For imports, it shows the number of countries from which goods are imported.

5. Trade by commodity and activity — Trade by commodity and activity sector allocates the trade of each commodity to the activity of the trading enterprise. This indicator shows which sectors were involved in the trading of each product group.

6. Trade by type of trader — This indicator provides information on how traders are involved in international trade. It shows the number of companies trading within only one flow or in both flows and the trade value these companies account for.

7. Trade by type of ownership — The type of ownership is referring to the concept of control and to affiliation of an enterprise. It indicates whether an enterprise is domestically or foreign controlled and, if domestically controlled, whether it has affiliates abroad or not. This indicator can be used to analyse the impact of globalisation on international trade and to estimate the importance of multinational companies for trade.

8. Trade by export intensity — Export intensity categorises enterprises according to the importance of foreign markets in their sales. It refers to the share of exports in total turnover.

9. Trade by activity sector — In comparison with trade by activity and enterprise size class (first dataset), this indicator provides more details on the activity sector (2- or 3-digit level) but does not contain information about the enterprise size.

10. Trade by partner country and size class — This indicator aims to give insights into the internationalisation of small- and medium sized enterprises. It complements indicator 3 on trade by partner country and activity by applying the same detailed breakdown of partner countries but categorising enterprises by size class instead of activity sector.

Data for Turkey are available for datasets 1 to 6.

Classification of economic activities

Economic activities are classified according to the statistical classification of economic activities in the European Community (NACE Rev. 2). NACE Rev. 2 is based on the fourth revision of the United Nations International Standard Industrial Classification of All Economic Activities (ISIC Rev. 4). Within the international trade in goods statistics, the NACE classification refers to the economic activity of enterprises that are active in international trade in goods.

Product classification

As the TEC domain aims to categorise trade flows according to economic activities, product classifications which are based on the industrial origin of the goods are more suitable for analysis than classifications based on material of goods. For this reason, the Classification of Products by Activity (CPA) is used as the product classification in TEC. CPA is a European version of the United Nations Central Product Classification (CPC), but arranged so that each product heading is assignable to a single heading of the European activity classification, the NACE Rev. 2. CPA version 2008 is used for TEC data relating to the reference years 2012-2015. CPA version 2.1 is used since 2016 as reference year.

Country classification

Except for the cases listed below, the reporting and partner countries are classified according to the Nomenclature of countries and territories for the external trade statistics of the Community and statistics of trade between Member States, known as the Geonomenclature. An alpha-2 coding applies, which means that each country is identified with a two-letter alphabetical code. See the publication Geonomenclature applicable to European statistics on international trade in goods for more information. Exceptions: code CN_X_HK instead of CN for China (except Hong Kong); code UK instead of GB for United Kingdom; code EL instead of GR for Greece.

All classifications and correspondence tables are available on Eurostats metadata server RAMON

TEC data cover all activity sectors, from sections A to U of the NACE Rev. 2 classification.

Trade value

The value of traded goods is calculated at the national frontier, on a FOB basis (free on board) 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.

Number of enterprises

The number of enterprises consists of a count of the number of enterprises involved in trade during at least a part of the reference period. For intra-EU trade, VAT data are used to identify the smallest traders (and to estimate their trade value), which are exempted from Intrastat reporting. These traders account for a limited share of the trade value. In line with the legal requirements, this share should not exceed 3 % of the total value of the intra-EU exports and 7 % of the total value of the intra-EU imports. However in terms of number of enterprises the smallest enterprises below threshold trade make the majority.

Partner country

Trade flows are broken down by partner country.

• For exports it is the country of destination of the goods. That is the last country to which it is known that, at the time of export, the goods are to be delivered.
• For imports, the definition of the partner country differs between Intrastat and Extrastat. For extra-EU imports it is the country of origin of the goods; for intra-EU imports it is the country (EU Member State) of consignment of goods.

Product

The product is the outcome of economic activity and the generic term used for goods and services.

Product classifications are designed to categorise goods and services that have common characteristics. They provide the basis for preparing statistics on the production, consumption, international trade and distributive trade. However, the scope of TEC is limited to the trade in goods.

Economic activity

The economic activity consists in offering goods and services on a given market. An activity is characterised by an input of products, a production process and an output of products. In other words, an economic activity is said to take place when resources such as equipment, labour, manufacturing techniques, information networks or products are combined, leading to the creation of specific goods or services.

Classifications of economic activities are designed to categorise data that can be related to the unit of activity. They provide the basis for preparing statistics of output, the various inputs to the production process, capital formation and the financial transactions of such units. Economic activities are classified according to NACE, the classification used to classify economic entities (enterprises, local units and similar statistical units). Within TEC, the NACE classification refers to the economic activity of traders, i.e. enterprises that are active in international trade.

Number of employees

The number of employees refers to the number of those persons who work for an employer and who have a contract of employment and receive compensation in the form of wages, salaries, fees, gratuities, piecework pay or remuneration in kind. A worker is considered to be a wage or salary earner of a particular unit if he receives a wage or salary from the unit regardless of where the work is done (in or outside the production unit).

The number of employees is a mandatory variable to be recorded in the business registers for each enterprise and local unit. According to the Business Register Regulation, the intention is to use the situation at the end of the year. However, as the end date approach is not harmonised the annual average can also be used as reference.

Type of traders

In the context of the TEC data, the type of trader specifies the type of trade activity of the enterprise. It indicates whether the enterprise is involved only in exports or only imports or trade in both flows.

The type of trader aims to describe the heterogeneity of enterprises according to their involvement in trade.

Type of ownership

In the context of the TEC data, the type of ownership refers to the concept of control and to the affiliation of an enterprise. It indicates whether an enterprise is domestically or foreign controlled and if it is domestically controlled, whether it has affiliates abroad or not. In other words, the type of ownership refers to the delineation of enterprise groups and categorising them. In this context, the concept of control prevails as referred in article 3 (4) of the Business Register Regulation (EC) No 177/2008. This Regulation applies the European System of Accounts (ESA) definition for the control as set out in point 2.26 of Annex A to Regulation (EC) no 2223/96. The concept of control prevails also in the FATS Regulation and is defined as follows: "‘control’ shall mean the ability to determine the general policy of an enterprise by choosing appropriate directors, if necessary. In this context, enterprise A is deemed to be controlled by an institutional unit B when B controls, whether directly or indirectly, more than half of the shareholders’ voting power or more than half of the shares". This definition is consistent with the ESA definition.

The type of ownership aims to describe the heterogeneity of enterprises according to their global status. A distinction of enterprises into domestically and foreign controlled enterprises has specific interest because of the important role of foreign affiliates. Furthermore, if domestically controlled enterprises with own affiliates abroad are further distinguished from all domestically controlled enterprises, the population all of multinational enterprises can be identified.

Exports intensity

The exports intensity refers to the share of exports of turnover (ratio between exports and turnover).

Exports intensity categorises enterprises according to the importance of foreign markets in their sales. The recent developments in the area of global value chains have raised a question on the heterogeneity of enterprises. It has been traditionally assumed that enterprises in the same activity sector are homogenous in terms of their productivity as well as in generating value-added and employment. However, this may not be a valid assumption any more in the globalised economy as productivity, value-added and employment may depend on the international orientation of enterprises, i.e. their involvement and position in the global value chains. Enterprises with high exports intensity are often also large-scale importers.

Enterprise

The statistical population should comprise all the enterprises involved in intra- and extra-EU trade flows. However, in practice, the linkage between the Trade Register and the Business Register is not systematically straightforward as there may be more complicated linkages or the linkage may not always provide expected outcomes. This relates in particular to the following cases:

• Intra-annual business demography changes;
• Large and complex businesses;
• Incomplete business register data; and
• VAT-groups.

The reference population used in the compilation of TEC datasets relates to traders who have reported trade transactions under a valid ID number and were successfully matched with the Business Register. This means that the enterprise characteristics reported in the TEC datasets refer only to a part of total trade. Are out of scope:

• Adjustments for missing trade (trade below threshold and non-response in intra-EU trade; missing, delayed and incomplete records for extra-EU trade);
• Trade carried out by non-resident traders as such traders cannot be associated to an enterprise via the national Business Register; and
• Trade carried out by private individuals.

Not applicable

Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.

According to the Statistics Law of Turkey No: 5429

(1) Foreign trade statistics are published by TurkStat.

(2) TurkStat is authorized in determination of methods and calendar of publication of statistics.

(3) Data are collected for statistical purposes and “passive confidentiality” is used.

According to the Article 13 of Turkish Statistical Law, confidential data can be accessed only by the ones involved in the production of official statistics, to the extent that they need for performing their duties properly. If the number of the statistical unit in any cell of the data table formed by aggregating the individual data are less than three or one or two of the statistical units are dominant even if the number of units is three or more, the data in the concerned cell are considered confidential. 

The  confidential  data  compiled,  processed  and  preserved  for  the  production  of  official  statistics  cannot  be delivered  to  any  administrative,  judiciary  or  military  authority  or  person,  cannot  be  used  for  purposes  other  than statistics or as an instrument of proof. Civil servants and other staff in charge of compiling and processing these data are obliged to comply with this rule. This obligation continues after the related personnel leave their duties and posts. 

The rulers of the institutions and organisations producing official statistics shall take all measures to prevent any illicit access, use or revelation of the confidential data. 

Data or information obtained from sources that are open to all people shall not be deemed confidentiaL.

Data  confidentiality  ceases  when  a  statistical  unit  gives  written  approval  for  the  revelation  of  confidential data concerning itself. 

Confidential data can be published only as combined with other data so as not to allow any direct or indirect identification. 

(Additional clause: 25/11/2008-5813/2 article)

For the data considered confidential due to the indirect identification in foreign trade  statistics, these confidentiality rules are implemented when a statistical unit applies with a written application requiring consideration of its data as confidential.

In principle, suppressions are made on commodity code. If this application isn't enough, net mass, partner country, customs can be suppressed.  

Confidentiality policy for TEC data is passive confidentiality except for table 6.

Confidential data is defined as ‘data which allow statistical units to be identified, either directly or indirectly, thereby disclosing individual information. To determine whether a statistical unit is identifiable, account shall be taken of all relevant means that might reasonably be used by a third party to identify the statistical unit’.

For TEC data, the principle of active confidentiality applies, which means that the National Statistical Authorities (NSAs) take the initiative to suppress the data whose dissemination by Eurostat would make it possible to identify an enterprise or a trader. The legal provisions (articles 13a (8) of Regulation (EC) No 1982/2004 and 15(9) of Regulation (EU) No 113/2010, respectively relating to the compilation of statistics on trade by enterprise characteristics for intra- and extra-EU) define only the principle to be applied. The application of confidentiality in practice is under the responsibility of the NSAs. Each NSA should establish the rules to define confidential data. This implies also that it is the reporting countries’ responsibility to mark their data as confidential before their transmission to the Commission (Eurostat).

For the data considered confidential due to the indirect identification in foreign trade statistics, these confidentiality rules are implemented when a statistical unit applies with a written application requiring consideration of its data as confidential. Written application should include; VAT number of statistical unit, address and contact information, flow and for which commodity code(s) will be confidential.

TEC data is produced by using foreign trade statistics and business registers. There is no extra burden for this study.

As data are generally deemed to be final at the time of transmission to Eurostat, most reporting countries have no formal revision policy. However should any major revisions occur in the context of the compilation of monthly trade in goods statistics, these should be reflected in the TEC data, which should be revised accordingly, and re-transmitted to Eurostat.

Eurostat accepts any data revisions insofar as they comply with all validation rules.

There is no official policy for revising TEC.

Statistics by enterprise characteristics are only exceptionally revised by the countries.

Not applicable.

International trade in goods statistics by enterprise characteristics are derived from two data sources: the monthly detailed trade in goods data and data taken from the business registers.

Trade in goods data are collected on the basis of:

• a census for the intra-EU trade, the census units being the traders whose annual trade value is above the national Intrastat exemption threshold and who are then liable to submit an Intrastat declaration; and
• administrative forms, the customs declarations, for the extra-EU trade.

Note that missing data (exempted intra-EU traders, missing Intrastat declarations, incomplete or delayed customs declarations) are estimated by the National Statistical Authority in order to disseminate trade in goods data covering 100% of the trade but those estimates are not part of the TEC data.

The national business registers serve as the sources for the enterprise characteristics. No samples are drawn from the registers, but the full registers are processed. Some differences in the coverage among the countries can occur. Different administrative sources depending on national law, as well as surveys, are used to update the business registers, and in some countries VAT thresholds for registration apply.

Collection of trade in goods data

• For intra EU trade, any VAT-registered business that trades goods with other EU Member States is required to provide information on its transactions. The information is obtained directly by the national authority responsible for the collection of trade in goods statistics, using the various media available (in paper or electronic form). All businesses are legally required to provide information on their total sales and purchases to and from other EU countries on their VAT returns. The largest ones also submit Intrastat declarations on a monthly basis within a fixed deadline.
• For the compilation of extra-EU trade statistics, the standard data source is the customs declaration submitted by businesses and, in some cases, by private individuals involved in an international transaction of goods with a non-EU country. The customs declaration may be in paper form — the Single Administrative Document (SAD) — but is most commonly in electronic format.

Collection of data for the Business Register

The maintenance of business registers is normally based on the effective use of various administrative and statistical data sources. The frequency of updating the business registers depends on the kind of unit, the variable considered, the size of the unit and the source generally used for the update. As a general rule, key characteristics such as economic/stratification variables should be updated annually. Characteristics which are considered to evolve rapidly or are regarded as key units by users should be updated more frequently. Examples include large and complex units and units classified to economic activities which are known to change frequently.

TEC data disseminated by Eurostat have passed the following quality checks:

• Intra-dataset checks: completeness of each dataset and uniqueness of the records, validity of the codes, validity of code combinations across the different dimensions, inter-record consistency checks;
• Inter-dataset checks: consistency of trade values and numbers of enterprises related to similar combinations across the datasets;
• Intra-domain check: check of the coherence between trade values published in TEC datasets and trade values coming from aggregated and detailed trade in goods data.

See the section ‘Data validation’ of the European business statistics compilers’ manual for international trade in goods statistics – trade by enterprise characteristics for information on the main validation rules implemented.

The TEC data is prepared according to "European business statistics compilers’ manual for international trade in goods statistics - trade by enterprise characteristics" for TEC so its coherent with EU requirements.
