|03.1. Data description|
Ineranational trade in goods - includes all goods that are added to the reserves of material wealth of the country when entering or leaving their economic territory (imports) from exit from it (exports).
The Trade balance is the difference between the total value of the expotred goods and the total value of the imported goods.
The deficite is a negative trade balance, and surplus is a positive trade balance.
international trade in goods is a raw data that, apart from the flows of goods (exports and imports), can be broken by periods (for example, months) and more classification and classification levels.
External trade statistics represent aggregates of exports and imports by:
Each of these aggregates on exports or imports can be considered as one indicator.

|06. Institutional Mandate||Top|
|06.1. Institutional Mandate - legal acts and other agreements|
The compilation of data on the Serbian international trade in goods is based on a set of laws, legal acts and regulations that are passed by the Serbian Assembly and the Government.
The basics documents are:
Other significant domestic documents:
Apart from the national legislation, international recommendations and legal acts are directly applicable.
Among them, the publications International Merchandise Trade Statistics: Concepts and Definitions (Series M, No. 52, Rev. 2) released in 1998, and IMTS 2010, which was passed on the 41th Commission session held from 23 – 26 February 2010, create the key international standards to be applicable in order to achieve international harmonisation. Our external trade statistics adopted almost all recommendations contained in the subject documents. Another important source of recommendations and acts are those adopted by the EU for external trade statistics with non-member countries (Extrastat basic regulation No. 471/2009 and other accompanying acts), as well as Statistics on the trading of goods – User guide (methods and nomenclatures), European Commission, Eurostat.
|06.2. Institutional Mandate - data sharing|
The external trade statistics regularly transmit monthly data to Eurotat, the IMF, WTO, OUN, CEFTA organization, national users such as ministries, the National Bank and others.
|07.1. Confidentiality - policy|
Regulations relating to data confidentiality:
|07.2. Confidentiality - data treatment|
The Republic Office of Statistics in the field of external trade data applies passive confidentiality in cases where importers or exporters, state authorities and other institutions require statistical authorities not to publish data that could cause damage to them or for state interests.The exception is military goods and the rule of active confidentiality, which implies that the statistical authorities themselves undertake an initiative to potentially protect data, either because of state interests, or because of the interest of individual economic entities. SORS publishes and submits information on the total statistical value of military goods under the special statistical code 99999399, and in the case of data according to the economic characteristics of the enterprise, a flag is placed, if the number of the enterprise is less than 4 in the corresponding field of activity classification.

|11. Quality management||Top|
|11.1. Quality assurance|
The main dimensions of quality measurement in external trade statistics are:
|11.2. Quality management - assessment|
The methodology of External trade statistics is largely aligned with the Eurostat principles and international recommendations. The development of methods for the further improvement of data quality is unavoidable and is aimed at full harmonization with European statistics.
The estimates of the quality of external trade statistics in accordance with the main dimensions are shown in the Quality Report, which is done at Eurostat's request.
According to the results of the Customer Satisfaction Survey from 2017, conducted by SORS, about 70% of users assess the quality of data as very good and good.
|12.1. User needs|
The needs of key users of International trade in goods statistics (ministries, embassies, business entities, state administration and local self-government, international organizations, media, individuals and others) are largely met.
|12.2. User satisfaction|
External trade data are fully compliant with relevant EU and UN regulations, recommendations and guidelines.
|13. Accuracy and reliability||Top|
|13.1. Overall accuracy|
The overall accuracy is at a high level, taking into account all concepts and definitions that are in line with international EU and OUN recommendations. The overall accuracy is influenced by the controls and revisions of the data that are carried out at the monthly and annual level.
|13.2. Sampling error|
|13.3. Non-sampling error|
The accuracy of the data is influenced by the rules on confidentiality of data, as well as the errors in the calculation of the values and the amount of the unit of measure that are corrected within regular monthly controls.
|14. Timeliness and punctuality||Top|
Monthly detailed data reveals that about 30 days pass between the reference moment and the moment of availability of data. The delay is shorter than what the UNSD allows (45 days) or prescribes the International Special Data Dissemination Standard (8 weeks).
Timeliness is high, all publications and press releases are published on time, according to the official calendar of publications.
|15. Coherence and comparability||Top|
|15.1. Comparability - geographical|

Data are produced on the basis of concepts and methods defined in EU and OUN legislation.

|17. Data revision||Top|
|17.1. Data revision - policy|
Every month, the data is revised, on the basis of which the indicator is calculated, from the beginning of the year to the month for which data are available, but the revision of the indicators of the total external trade exchange is carried out once a year, five and a half months after the publication of the preliminary values.
|17.2. Data revision - practice|
Due to the different nature of the data revision, the data of the first and previous revision for the reference year can sometimes be significantly different.
Users were informed of revisions via the SОRS website.
The revision of the published final data of the Statistical Office of the Republic of Serbia is done only in the case of methodological adjustment with the concept and definitions of the UN.
|18. Statistical processing||Top|
|18.1. Source data|
|18.2. Frequency of data collection|
|18.3. Data collection|
The main instrument for compiling external trade statistics is customs declaration (Single administrative document) and for the electricity of the Excel table of the "Elektromreža Srbija". Therefore, statistical information is dependent on customs practice, definitions and policies, and only a few are collected exclusively for statistical purposes. Dependence on customs procedures implies a high level and almost complete coverage of External trade statistics
|18.4. Data validation|
Controls can be performed on input data (declaration level) or output level (data generated for publication). The Statistical Office of the Republic of Serbia carries out all the controls at the level of the declaration.
Basic controls - include the validation of data and usually relate to all the collected variables. Examples of errors discovered in this type of control can be inaccurate or missing codes, missing values in declarations; inadequate number of digits in the numerically defined field, etc. ...SORS uses reference tables with an automatic process of controlling and detecting the type of error.
Complex controls - include checking the accuracy of data and evaluating all possible data-related errors. The data satisfy the aforementioned control criteria, but are probably incorrect, and can therefore be processed, but if the statistical analysis is excluded. The methods used by the RZS consist of checking one value in relation to another within the declaration or between declarations.
External trade data can also be checked against other sources. For example: balance of payments, data from business registers, VAT data, partner country data, etc. The purpose of these secondary sources is to provide additional information that can be used to verify the authenticity of data or as verification of trader declarations.
|18.5. Data compilation|
The process of data processing of external trade consists of the following stages:
If necessary and in accordance with the UN concept and definitions, that is, the standards existing in the EU, various methodological adjustments are made.
