The PRODCOM survey is conducted by National Institute of Statistics. This is an annual survey of the value and volume of products produced by industrial enterprises in Romania and sold production  during the reference year.
It is carried out in compliance with European Parliament and Council Regulation on European business statistics, repealing 10 legal acts in the field of business statistics (No 2019/2152) and Commision Implementing Regulation (EU) (No 2020/1197)  laying down technical specifications and arrangements pursuant to Regulation (EU) 2019/2152

The PRODCOM survey provides information on PRODuction of the European COMmunity and is compiled from data received from Romania manufacturers.

The survey sample is 15530 entreprises, covering 228 NACE 4-digits clases industries, derived from sub-sectors of the total manufacturing sector. There are 5108 products for total survey (B, C and D section of NACE rev.2) of which 4915 products for manufacturing sector.

Since 2001, NIS Romania developed a national product classification, named PRODROM which detailed the european classification PRODCOM; this national classification contains 5108 codes out of which 174 have no link with PRODCOM codes.

The link between PRODCOM and PRODROM is  1-to-N at each product level.

Our national classification covers NACE Rev.2 classes from 0510 to 3530.

PRODROM uses 9-characters product code of the form XX.XX.XX.YY.N:

• The first four digits of the code correspond to the 4-digit classes of NACE Rev. 2.
• The first six digits are the Community Classification of Products by Activity (CPA) codes. The CPA provides a detailed listing of the characteristic products for each 6-digit NACE Rev. 2 economic activity.
• The next  two digits provide a more detailed breakdown of the CPA classes into PRODCOM product headings.
• The last digit is specified to Romanian products classification; if there are national products codes, without link to PRODCOM classification, the last digit is 'N'.

For the Romanian product code with no link to PRODCOM classification the code is composed by CPA code 6-digits, followed by '00' and 'N'.

The link between PRODROM and the EU foreign trade Combined Nomenclature (CN) is realised by PRODCOM codes.
There is a direct link between the PRODCOM classification and the EU foreign trade Combined Nomenclature (CN).
Each PRODCOM 8-digit heading covers one or more CN 8-digit headings.

The survey covers:

• all enterprises with 20 and more employees, which are carring the main activity in NACE Rev.2 sections: B, C, D
• all enterprises with non-industrial main activity, but with KAU and 50 employees in NACE Rev.2 sections: B, C, D

In order to reach 90% representativeness we include in survey, for some industrial NACE classes, all enterprises with significant turnover in the respective domain.

The purpose of the statistics is to report, for each product in the Prodrom List, how much has been produced in the reporting country during the reference period. This means that Prodcom statistics relate to products (not to activities) and are therefore not strictly comparable with activity-based statistics such as Structural Business Statistics. The NACE codes on which Prodcom codes are based merely serve to identify the enterprises that should be surveyed in order to determine the amount of production of the product.

The products: the Prodrom List defines the products to be included in the survey. There are approximately 5108 headings representing manufactured products and some industrial services.

In Romania, the PRODROM survey collects information on the following variables:

- Sold production (value and volume): the sold production is defined as the production carried out at any time and within the national economic territory, which has been sold (invoiced) during the reference period, that has been invoiced and shipped by the company, according to the destinations provided in contracts or orders
The value is expressed in national currency and the volume is expressed in a specific unit for each product

- Sold production under subcontracted operations (value and volume): the production under sub-contracting operations refers to the production carried out by a sub-contractor in the national economic territory, which has been sold (invoiced) during the reference period to customers, under the conditions of the sub-contracted operations.

Two enterprises are linked by a subcontracting relationship whenever the conditions below are met together:

       1. the customer enterprise participates in the conception of the product providing (even partially) technical specifications to the supplier enterprise (sub-contractor) and / or provides it with the materials to be processed;

       2. the customer enterprise sells the sub-product (as such or as part of a more complex product) and takes on after-sales liability for the product.

The distinction between customer and sub-contractor is based on the principle of main material input. The value of the material inputs provided by the customer to sub-contractor will be used as a criterion for identifying the main material input. When the value of the input material held by the customer is difficult to identify it is recommended to use the contractual relationship between the two parties and to consider who owns the final product.

- Actual production (volume): the actual production includes any production, carried out during the reference period and within the national economic territory, which is incorporated into the manufacture of other products. It includes those products which: are intended for sale, are processed into another product, are fitted into another product or are put into stock.

 We also collect information about:

• Stock at the beginning of the year
• Productive internal consumption
• Stock at the end of the year

The observation unit and the reporting unit is kind of activity unit (KAUs)

The survey population consists of all industrial enterprises in NACE 05–35.

All the Romanian teritory is covered.

No regional breakdown

The period observed is one calendar year.

Romanian industrial production statistics according to PRODCOM List date back to 2003.

There are historical data, at agregate level according to the old Romanian classification, starting from 1994.

Not applicable.

The volume is expressed in a unit of measure specific to each product.

  The value of sales is collected and stored in the national currency (RON), transmitted to Eurostat in thousands of RON, and released in EURO in the Eurostat's database;

Year 2022

This survey is carried out in compliance with following regulations:

• At EU level:
• Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics, repealing 10 legal acts in the field of business statistics (EBS-Regulation) 
• Commission Implementing Regulation 2020/1197 laying down technical specifications and arrangements pursuant to Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics repealing 10 legal acts in the field of business statistic (General Implementing Act)
• At National level:
• The data collection right is stipulated in our Law on the organisation and functioning of official statsitics no 226/2009  article 2 and 10.

Not applicable at MS level.

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.

The Statistical law of Romania stipulates that the following data is confidential:

• individual statistical data;
• statistical data which can be matched in a way that enables the identification of a specific statistical unit;
• statistical information which aggregates data about less than three statistical units or about a population in which the relative share of the value of a surveyed parameter of a single unit exceeds 80 per cent of the total value of such parameter for all units in the population.

Romania is applying the principle of the active confidentiality.

The policy of Statistics of Romania on confidentiality of Prodcom data it stipulates that a specific code is flagged as confidential only if at least one of the following two criteria are met:

• the largest reporting company has a share over 80 pct. of total sales of the commodity
• there are less than 3 companies reporting production of the commodity (stock, internal consumption, sold)

If there are any changes to the pre-announced release schedule, public attention will be drawn to the change and the reasons for the change will be explained fully at the same time, as set out in the Code of Practice for Official Statistics.

PRODCOM data are collected and disseminated annualy.

Data from PRODROM annualy survey are disseminated on CD (in Romanian language at PRODROM level). The CDs contain data agregated at PRODCOM/PRODROM level: measure unit, product's name; initial stock, actual production, internal consumption, sold production, final stock, value of sold production in RON

The data are available on CDs which is available on INS website (http://www.insse.ro/cms/en/publicatii-statistice-in-format-electronic)

Romanian Prodcom data are disseminated on Eurostat's database.

The main documentation is an internal desk manual describing the statistical production process.

For users, the main documentation is the Quality Declaration.

In addition, the variables are documented in a metadata tool called Metadata Database, available through the web site of Statistics of Romania.

The main documentation is an internal desk manual describing the statistical production process.

A "Quality Declaration" is available at http://www.insse.ro/cms/files/eurostat/NIS%27%20Quality%20Declaration.pdf

For PRODCOM survey (national version) NIS Romania elaborates an user oriented quality report.

The main instrument for quality monitoring and assurance for Statistics of Romania are the Quality Declarations, available here.

Punctuality and any errors in published data are systematically monitored.

The main quality assurance activity for Prodcom is the data validation (see 18.4 concept)

Prodcom is published with a high level of detail, its accuracy therefore depends on data being checked in several ways.

Prodcom is produced in close cooperation with the STS manufacturing indices, enabling data reported to the two surveys to be checked against each other.

Prodcom data are also checked with SBS data at unit level.

The Information System provides a number of arithmetic and logical controls, both mandatory and optional between the items in each form and between the forms in the whole annual report. There is a number of arithmetic and logical controls inside the PRODCOM form.
The System calculates both the totals and the unit price.
The suplied PRODCOM data is crosschecked against SBS data, PRODCOM data of the previous year and monthly PRODROM survey.
If there are interlinked errors, they are displayed after the validation of the whole set of reports.

The main users of PRODCOM data can be presented in different groups, namely:

EXTERNAL/ INTERNATIONAL (OUTSIDE NSI), like:

• Institutions at European level:Eurostat
• Multi-national organizations:United Nations

EXTERNAL/ NATIONAL (OUTSIDE NSI), like:

• Institutions at national level - governmental

GOVERN

• Ministry for Economy
• Ministry of Agriculture and Rural Development

We conduct a user satisfaction survey every three years. The latest one was in 2021.

The publication can be found at the following link:

This publication presents the way in which the statistical data produced and the methodological information of the INS meet the information needs of the various user categories. It includes a presentation of the main results of the statistical survey on the "Satisfaction of statistical data users”, respectively the profile of INS statistical data users, the confidence in the INS and the statistical data produced by INS, the assessment of the quality of the data produced by INS

Views from the main expert users are collected from bilateral meetings with representatives from the main industry organisations and ministries.

All requested data are delivered to Eurostat.

In 2022, the response rate to the PRODCOM Survey was of 85.29% out of all enterprises surveyed.

There is no data available for item nonresponse.

Non-respondents units were imputed from Monthly Industrial Production.

The survey is done as a cut-off sample, all units above a threshold are included. There is no grossing up for units below the threshold. It is therefore not relevant / possible to calculate sampling error.

The errors occur due to the human factor and can be grouped in:

• errors in data compilation (like wrong codification of product, provide data in different units than the requested ones, ....)
• data entry errors in survey databases (like errors from shifting columns and rows from questionnaire, introduction of incomplete data, ...)
• Imputation rates (2021):   unweighted imputation rate (number of items)

Preliminary data are sent to Eurostat at 6 months after the end of reference year and final data are available and sent to Eurostat 11 months after the end of reference year.

The data from anually PRODCOM survey is published by NIS Romania on CD  within T+11 months.

The statistics are mostly published without delay, in relation to the scheduled date.
For at least the last 17 years, there have been no delays in releases.

Not applicable at MS level.

An extensive revision of NACE in 2007 has resulted in changes to PRODCOM estimates for the 2008 survey onwards.

The time series for PRODCOM start with 2003; in 2008 is a break in time series due to the revision of NACE classification.

Starting with the year 2021, a break down  of series is recorded as a result of the fact that the production under sub-contracted operations has been collected separately from the own account production (as a result of the implementation of the EBS Regulation).

Consistency checks are done at micro and macro level with STS, SBS and external trade.
These checks involve the examination of the aggregated returns for PRODCOM, ensuring that these are consistent; where there are differences, the cases are further scrutinised and corrected, if necessary.

Coherence ensured.

For 2022, the burden on respondents has been calculated as a total duration of 29437 hours. The estimated number of hours worked spent by one respondent to fill in the questionnaire is 2.31 hrs.

Revision are in conformity with standards and as is described in the NIS Revision Policy (http://www.insse.ro/cms/en/content/revision-policy).

The general Calendar of Revision  is available on the NIS Website (http://www.insse.ro/cms/en/content/revision-policy).

Data are transmitted to Eurostat at the end of June were preliminary and revisions were sent in November.

When submitting a new year's Prodcom data to Eurostat, Statistics of Romania will also submit revised versions of previous years when relevant.

The survey sample is selected from Romanian Business Register. PRODCOM estimates cover enterprises classified to NACE divisions 05 through to 35. Enterprises are selected by employment size and NACE class.

The sample covers:

• all enterprises with 20 and more employees, which are carring the main activity in NACE Rev2.Sections: B, C, D
• all enterprises with non-industrial main activity, but with KAU and 50 employees in NACE Rev2.Sections: B, C, D.

In order to reach 90% representativeness we include in survey, for some industrial NACE classes, all enterprises with significant turnover in this field.

The sample is updating once a year.

Monthly and annualy

PRODCOM data collection is decentralized, organized through the County Statistical Offices (42 counties). Data validation is carried out separately at regional and national levels.

The NSI of Romania uses paper questionnaires for anual survey and on-line questionnaires for monthly survey.

The paper questionnaires contain the entire list of products reported by the enterprise in the previous survey. The list of products is available at each one of the County Statistical Offices.

In Statistics of Romania the data are validated through a number of controls that check against last period as well as against other companies reporting under the same codes (unit price control).

Data are also checked against other sources: monthly PRODROM survey, SBS survey, external trade data. These checks are especially useful to spot the underreporting or the errors in codification of the products.

In order to have a consistent products coding, NIS Romania established a team of experts in charge with this issue. All responsibles from Counties Statistical Offices who have questions in this matter are adressing their requests to the mentioned team, in order to provide a homogenous coding of products.

The following steps can take place at level of the County Statistical Offices:

• receive of the paper questionnaires;
• data entry in a local database;
• running of the IT tools for detecting the errors; data are  corrected where necessary.
• checks against SBS data are done and data are corrected where necessary, after a disscusion with the enterprise.

At Central Statisticaly Office, the folowing actions are taking place:

• checks made against previous years data, and where necessary the enterprises are contacted through the Regional Statistical Offices
• for all enterprises data from Monthly Industrial Production is compared to ensure consistency between the sources.

Typically, one month before the Eurostat deadline of t+6 months, the survey is closed down and a clean file is generated.

For unit non-response cases there are done imputations from Monthly Industrial Production.

When the PRODCOM survey population is selected from the Business Register, a detailed analysis is carried out by Business Register and Industry staff regarding the new births. If there are issues detected, they are fed back to Business Register.

At national level, data are published monthly from Monthly PRODROM Survey. Monthly data are used to compile Industrial Production Index.
