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.

11.1. Quality assurance
Currently, quality assessment is not generally available to the public.
11.2. Quality management - assessment
Risks to the data quality lie in the provision of wrong information by importers and exporters or their representatives. Risk based plausibility checks are run to minimize this risk.
Out of schedule revisions and delayed publication data are rare incidents.
Client satisfaction as observed in client contact is high.
12.1. Relevance - User Needs
Users, in descending order of importance, are administrations, trade associations, journalists, researchers and consulting companies and individuals.
Customer support is available via phone and e-mail, allowing to meet user needs within the limits of confidentiality.

Publications at national level: 100% (2015)
Data delivery to Eurostat: no delayed data delivery (2015)

Limited symmetry of trade data can arise due to differences in methodology. Switzerland applies the Special Trade System and has its methodology harmonized with that of the EU.
15.2. Comparability - over time
Efforts are made to provide data as much as possible consistent over time.
The consequences of changes brought by HS revisions are traceable through our database or the documents available on our website in French, German and Italian.
Changes to geographic classification can be reconstructed by files provided on our website in French, German and Italian.
Data is available according to SITC rev. 4 after 2006, while data from 1988 to 2005 is only available according to SITC rev. 3.
For the mode of transport, data is available according to NST/2007 after 2007, while data from 1988 to 2006 is only available according to NST/R. A concordance table can be found on our website in French, German and Italian.
Index data for chain indices uses 1997 data as base year.
Since 2012 the imports are published with a breakdown by country of origin (instead of the country of production). This change has caused a level shift in the data for some countries. For details, please refer to these explanations.
From 2012 onwards, total trade includes non-monetary gold, silver and coinages. The inclusion of those products has caused a major level shift.
A change in the definition of trade in electricity in January 2013 has led to a level shift in the related data. For details, please refer to these explanations.
15.3. Coherence - cross domain
Data is used in national accounts as well as balance of payment statistics.
For the balance of payment, a change of ownership is required for data to be relevant. According manipulation of foreign trade data takes place; such manipulations are displayed in the balance of payment, thus the data can be directly linked to foreign trade data.
Differences to trade data from other countries results mainly from different definitions and applied systems (General or Special Trade System).
15.4. Coherence - internal
In 2012 the concept of country of origin replaced the notion of country of production. This change has caused some shifts in the data by partner countries. For details, please refer to these explanations.
Only administrative data collected from custom declarations are used in the statistics.
Efforts are made to keep the burden that the declarations cause as low as possible.
17.1. Data revision - policy
Data is released as provisional data and only becomes definite data at in May of the following year.
Definitive data is only corrected if very severe errors are found in the data.
17.2. Data revision - practice
Major revisions on data that is already definitive are rare.
18.1. Source data
Administrative data from custom declarations is continuously gathered from importers and exporters or their agents through the electronic system eDec. Primary purpose is the implementation of custom related regulation. Potential deficiencies include wrong information being provided in declarations. Plausibility checks are carried out on micro- and macro data to minimize this risk.
18.2. Frequency of data collection
Data is collected continuously as cross-border movements of commercial goods take place.
18.3. Data collection
Importers and exporters are legally obliged to provide the information processed.
18.4. Data validation
Declarations are screened for errors and mistakes as well as for low plausibility.
18.5. Data compilation
Estimates of trade in electricity for the three latest periods rely on ARIMA models.
Procedures are in place to carry out risk adjusted checks on declaration data, as well as on aggregates to detect faulty data. Faulty data is corrected.
Index data is correct for outliers, working days per month and seasonal effects.
18.6. Adjustment
Relevant to index data only: Adjustments for outliers is based on an ARIMA model, adjustments for seasonal effects are based on an X12-ARIMA model.
