National reference metadata

Poland

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.

International trade in goods statistics (ITGS) published by Eurostat measure the value and quantity of goods traded between the EU Member States (intra-EU trade) and goods traded by the EU Member States with non-EU countries (extra-EU trade). ‘Goods’ means all movable property including electricity. ‘European’ means that the statistics 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 for extra-EU trade. The invoicing currency is the currency in which the commercial invoice is drawn up. Data by invoicing currency can be used for instance to explore the use of the euro in the EU’s international trade, to compare it with the role of the United States dollar (USD) or to analyse the role of the euro in the euro area and in the EU. 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;
  • partner country;
  • reference period;
  • trade flows;
  • product; and
  • currency.

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  ‘extra-EU’ for the EU Member States and Northern Ireland and ‘world’ for the EFTA and enlargement countries.

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). 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). Additionally, since 2021 reference period, TIC data are available also by 10 individual SITC sections.

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:

  • euro ('EUR');
  • UK pound ('GBP');
  • US dollar ('USD');
  • national currencies of EU Member States not belonging to the euro area (‘XU3’);
  • other not specified currencies (‘_X’)
  • unknown currency (‘_U’);
  • Total (‘_T’);
  • BRL, CAD, CHF, CNY, INR, JPY, KRW, MXN, NOK, RUB, SGD, TRY + national currency (PLN).

Note on ‘unknown’ currency: Trade for which the currency is unknown should be distributed over the individual currencies or groups of currencies proportionally to their relative share except if it is known that such a distribution would skew the data in a too significant extent. In such a case, the code UNK ‘Unknown’ could exceptionally be used.

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 2021 reference year.

The statistical unit is any natural and legal person lodging a customs declaration in Poland on the condition that the customs procedure is of statistical relevance.

The statistical population comprise all the legal or natural persons who lodged a customs declaration with the National Revenue Administration (Krajowa Administracja Skarbowa, KAS) and in whose structures there is, among others, the Customs Service.

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 Revenue Administration (Krajowa Administracja Skarbowa, KAS) and in whose structures there is, among others, the Customs Service..

The reference years for which TIC data are disseminated result from the aggregation of monthly figures from January to December.

See item 13.1 ‘Accuracy - overall' of the related metadata ‘ext_tic - International trade in goods – trade by invoicing currency’ for more details.

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.

At national level:

The data on invoicing currency are compiled from the ccustoms declarations.

At European level:

The share of each invoicing currency in the imports and exports of Poland is calculated on the basis of the transmitted trade values.

TIC data are mainly derived from the combination of two types of information collected via customs declarations:

  • Trade in goods transactions; and
  • The invoicing currency associated to these transactions.

TIC data are only disseminated by Eurostat. See item 9 ‘Frequency of dissemination’ of the related metadata ‘ext_tic - International trade in goods – trade by invoicing currency’ for more details.
