3. Statistical presentation Top
3.1. Data description

BiH international trade in goods statistics describes the trade in goods between Bosnia and Herzegovina and other countries. It is based on data from customs declarations (exporter/importer has to submit a declaration to Customs when exporting and importing goods). Export and import by products and partner countries are disseminated.

3.2. Classification system

- Customs Tariff of Bosnia and Herzegovina

- Combined Nomenclature (CN)

- Harmonized System (HS)

- Standard International Trade Classification (SITC rev.4)

- Statistical classification of economic activities in the EU (NACE rev.2)

- Classification of Products by Activity (CPA 2008)

- Main Industrial Groupings (MIG 2009)

Customs Tariff of BiH is the national classification of products used for customs and statistical purposes. It comprises ten digit codes and is in line with international classifications CN and HS.

3.3. Coverage - sector

Trade in goods of primary and secondary sectors.

3.4. Statistical concepts and definitions

- Flow (Export and import are determined using BiH customs procedure codes. They are generally in line with EU customs procedure codes with few exceptions).

- Reference date (It is the date of acceptance of customs declaration and approximates border crossing moment as reference point).

- Partner country (Geonomenclature 2013 codes are used. Partner country in the case of export is the country of the last known destination. Country of origin of goods is taken as importing country, but, in the case of import after outward processing and import of goods from chapter 97 of Customs Tariff of BiH, as well as incorrect codes or empty boxes for the country of origin in the Customs database, the country of consignment is taken as importing country. The country of origin of goods is the country in which goods were manufactured, and the country of consignment is the country from which the goods were dispatched to the importing country.

- Product code (defined in Customs Tariff of BiH which is in line with CN).

- Value (Expressed in convertible marks-national currency, euros and US dollars. The statistical value of exported and imported goods is determined at the national border. In the case of export, FOB-type values are used, meaning that the statistical value of goods comprises invoiced value agreed between buyer and seller, as well as the costs of transport and insurance from a destination in BiH to the BiH border crossing. In the case of import, CIF-type values are used, meaning that the statistical value of imported goods comprises contracted price of goods agreed between buyer and seller and the costs of international freight and insurance to the BiH border crossing.

- Net mass (kilograms).

- Supplementary quantity unit and supplementary quantity (as determined in Customs Tariff of BiH).

- Statistical procedure (Determined using conversion table between customs procedure codes and statistical procedure codes). The table was created by Eurostat.

3.5. Statistical unit

Statistical unit in the BiH international trade in goods statistics is any delivery of goods, exported or imported.

3.6. Statistical population

Special trade system (relaxed definition) is used. It means that BiH international trade in goods statistics comprises all the transactions related to normal export and import (goods cleared for free circulation) as well as goods for processing. The following transactions are excluded from statistics:

- Goods in simple transit: The reporting on operations in BiH is excluded when the goods travel directly through BiH or stop for reasons only related to its transport.

- Temporary trade: Goods moving abroad or entering BiH for a well-defined duration and without undergoing any change except normal depreciation (e.g. hire, operational leasing) are excluded.

- Particular trade that is not subject of a commercial transaction (e.g. advertisement material, commercial samples).

- Monetary gold.

- Repairs.

3.7. Reference area

Bosnia and Herzegovina

3.8. Coverage - Time

The data are disseminated on a monthly basis from 2005 onwards. 

3.9. Base period

The base year for production of export and import unit value indices is 2010.


4. Unit of measure Top

Statistical value is expressed in convertible marks (national currency), euros and US dollars.

Net mass is expressed in kilograms.

Supplementary quantity is expressed according to corresponding supplementary quantity unit from Customs Tariff of BiH.


5. Reference Period Top

The reference period indicates the calendar year and month when the declaration is assessed and accepted by Customs.

Three relevant dates are used: the declaration date, the registration date and the assessment date. The declaration date represents the date when the declaration was submitted (part of SAD box 54). The registration date represents the date when the declaration was registered i.e. became an official document recorded on computer (part of SAD box A). The assessment date represents the date when the declaration was assessed and accepted by the Customs (part of SAD box B).

The assessment date is used for statistical purposes. It is a good approximation of the time of crossing the border of the economic territory and conforms to international recommendations.


6. Institutional Mandate Top
6.1. Institutional Mandate - legal acts and other agreements

Agency for Statistics of Bosnia and Herzegovina is the institution responsible for production and dissemination of BiH international trade in goods statistics.

Statistical activities of the Agency for Statistics of BiH are regulated by the Law on Statistics of BiH („Official Gazette of BiH“, No 26/04 and 42/04).

10.7. Quality management - documentation

There are no standard quality reports. Quality indicators are described in the document “BiH Statistics on the Trading of Goods – User Guide”.


11. Quality management Top
11.1. Quality assurance

The production of BiH international trade in goods statistics is based on EU regulations and following documents: “Guidelines for the Implementation of the Intrastat and Extrastat Legislation” and “International Merchandise Trade Statistics - Concept and Definitions 2010”. The best practices of other countries are used as well.

11.2. Quality management - assessment

Overall quality is at satisfying level. Generally, the objective to provide robust, reliable, relevant and timely BiH international trade in goods statistics is achieved.


12. Relevance Top
12.1. Relevance - User Needs

The main users in BiH are government institutions:

- Ministry of Foreign Trade and Economic Relationships of BiH (planning of customs and trade policies),

- Directorate for Economic Planning – Council of Ministers of BiH (macroeconomic analysis and economic planning),

- Central Bank of BiH (production of balance of payment statistics).

The main international users are Eurostat and UNSTAT. 

Other users are e.g. private companies (market analysis) etc.

12.2. Relevance - User Satisfaction

The views and opinions of the users are collected through verbal and written communication (especially government institutions). Generally, users are satisfied with BiH international trade in goods statistics.

12.3. Completeness

All requested statistics and statistical variables are available, except statistics on trade by business characteristics.


13. Accuracy Top
13.1. Accuracy - overall

The accuracy of BiH international trade in goods statistics is affected by: coverage of data collection, measurement units, data revisions, confidentiality and control procedures (validity and credibility checks). These factors are described elsewhere in the document.

As basic data consists of many detailed customs declarations each month, it is difficult to reach complete accuracy for the published statistics. The users should be aware of the margin of inaccuracies in the data used, at least concerning the most detailed level of data.

13.2. Sampling error

No sampling techniques are used. Full coverage – customs data.

13.3. Non-sampling error

No sampling techniques are used. Full coverage – customs data.


14. Timeliness and punctuality Top
14.1. Timeliness

The data for the previous month are disseminated not later than the 20th of the following month.

Preliminary data for the previous year are disseminated not later than the 20th of January of the following year.

Final data for the previous year are disseminated in July of the following year.

Data are sent to Eurostat in accordance to the deadline specified in the Extrastat Basic Regulation (EC) 471/2009 (not later than 40 days after the end of monthly reference period). The data are sent according to the transmission rules specified in the Eurostat’s document Doc. Coop_400 Rev.2.

14.2. Punctuality

The Press Releases and Thematic Bulletins are always disseminated on time.

The data are always sent to Eurostat not later than 40 days after the end of monthly reference period.


15. Coherence and comparability Top
15.1. Comparability - geographical

The production of BiH international trade in goods statistics is based on EU regulations and following documents: “Guidelines for the Implementation of the Intrastat and Extrastat Legislation” and “International Merchandise Trade Statistics - Concept and Definitions 2010”.

Mirror statistics is used to compare data. Absolute discrepancy between BiH and EU data on both flows is 5-10% at the aggregated level (totals). At the detailed level of CN there can be discrepancies due to:

- Partner country definition,

- “Rotterdam effect”,

- CIF versus FOB valuation,

- Data confidentiality,

- Misclassification of goods.

15.2. Comparability - over time

BiH international trade in goods statistics is generally comparable over time since 2005. Comparability is affected by Harmonized System changes in 2007 and 2012 as well as changes in the Combined Nomenclature which occur every year.

Customs Tariffs of BiH were not fully in line with the corresponding Combined Nomenclatures in the period 2005-2007. Country classifications were not fully in line with the corresponding Geonomenclatures in the period 2005-2007. These are reasons for not putting the data for the mentioned period into Comext.

15.3. Coherence - cross domain

BiH international trade in goods statistics is used in the production of BiH National Accounts and BiH Balance of Payments. Still, the production of BiH National Accounts and BiH Balance of Payments follows somewhat different methods than BiH international trade in goods statistics. This can be the cause of data difference when comparing trade flows from the mentioned statistics.

15.4. Coherence - internal

BiH international trade in goods aggregated data are constructed from detailed data over countries and over different product classifications with the help of correspondence tables. This insures internal coherence.


16. Cost and Burden Top

Single Administrative Documents (customs declarations) are used by Indirect Taxation Authority (Customs) to implement BiH customs policy. Data from customs declarations are used to compile BiH international trade in goods statistics.


17. Data revision Top
17.1. Data revision - policy

Agency for Statistics of BiH does not have an official paper on revision policy.

17.2. Data revision - practice

Revisions are performed yearly. It is not necessary to revise data on a monthly basis due to minor changes in monthly data.

Revisions are based on the updates of the data provided by Customs. The provisional data for the previous year become available in January of the following year. The first revision is published in January in Press Release. The final data for the previous year become available in April/May of the following year. The second revision with final figures is published in July in Thematic Bulletin.

Users are informed about revisions in the methodology part of Press Release and Thematic Bulletin.


18. Statistical processing Top
18.1. Source data

BiH international trade in goods statistics is based on administrative data. The only source of data is the Indirect Taxation Authority (Customs) - Single Administrative Documents (customs declarations).

Indirect Taxation Authority (Customs) uses ASYCUDA for data processing.

18.2. Frequency of data collection

Monthly. 

18.3. Data collection

Indirect Taxation Authority (Customs) sends tables from ASYCUDA (data from Single Administrative Documents – customs declarations) to the Agency for Statistics of BiH in the form of Access database on CD. 

18.4. Data validation

There are two types of statistical data checks:

- Basic (validity) controls: this means checks on the validity of data and concerns all the variables collected. A validity error is found when a record is not correct therefore it may cause processing problems, it cannot be included in the statistical analysis and so it is removed or corrected. Examples of this kind of errors are incorrect or missing codes, missing values in the customs declarations, character data in numeric field and vice versa, etc.

- Complex (credibility) controls: this means checks on the accuracy of data and assessment of possible errors associated with the data. Some data passing the previous validity checks can still be incorrect. Residual errors can be pointed out by looking for variable inconsistencies (e.g. unit value of a product should not fall outside the predefined range).

Statistical data checks are of utmost importance for determining and improving data accuracy.

18.5. Data compilation

The compilation of BiH international trade in goods statistics is based on international recommendations regarding concepts, definitions and production of necessary indicators. Statistical data checks are performed and data errors are corrected. 

18.6. Adjustment

There are no data adjustments (e.g. seasonal adjustments etc.).
