Applying for certification  

If you have decided to apply for a VLOG certification for your company, you will find all important information on the certification process, the different types of certifications in the VLOG system and an overview of the further procedure on this site.

Fulfilment of the requirements in the VLOG Standard is the prerequisite for VLOG certification. The current version of this Standard can be viewed and downloaded at ohnegentechnik.org/en/standard.

1. Individual certification

Individual certification is the VLOG certification of a legally independent business (company) with one or more legally dependent sites. The fulfilment of the requirements of the VLOG Standard is checked in an on-site audit at the company and the sites included in the certification by a certification body recognised by VLOG.

      1.1. Documentary check:

For very small farms, the VLOG Standard does not require an on-site audit for entering the VLOG system, provided the size of the farm does not exceed a certain maximum value (depending on the animal species) or if a recognition of an external standard exists. Please contact VLOG for exact limits concerning the size of farms for individual animal species. For more information, please refer to part E1 of the VLOG Standard.

2. Group certification

      2.1. Agriculture:

Group certification agriculture is the merger of several legally independent agricultural companies into a VLOG group. A group consists of a group organiser and several legally independent group members, each with one or more locations. The group organiser takes over various tasks for the group members and their locations. Only the group organiser has to conclude a Standard Usage Agreement with VLOG and receives a VLOG ID. The fulfilment of the requirements of the VLOG Standard is checked in on-site audits at the group organiser and group members by a certification body recognised by VLOG. The VLOG certificate is issued for the group organiser. All group members to whom this certificate applies must be reported to the certification body in advance in a member list. For more information, please refer to Part F of the VLOG Standard.

      2.2. Retail:

The group certification retail is a group certification of branched stores. This group consists of a group organiser and several branches, which act as group members retail trade. The group organiser takes over various tasks for the group members. Only the group organiser has to conclude a Standard Usage Agreement with VLOG and receives a VLOG ID. The fulfilment of the requirements of the VLOG standard is checked in on-site audits at the group organiser and group members by a certification body recognised by VLOG. The VLOG certificate is issued for the group organiser. All group members to whom this certificate applies must be reported to the certification body in advance in a member list. For more information, please refer to Part H of the VLOG Standard.

3. Matrix certification

Matrix certification is the merger of several sites from the feed production and logistic sector into a VLOG matrix. One or more legally independent companies and their sites can be part of a matrix as matrix members. A matrix consists of the matrix organiser and at least two matrix sites. The matrix organiser takes over various tasks for the matrix members and their locations. Only the matrix organiser has to conclude a Standard Usage Agreement with VLOG and receives a VLOG ID. The fulfilment of the requirements of the VLOG Standard is checked in on-site audits at the matrix organiser and matrix members by a certification body recognised by VLOG. The VLOG certificate is issued for the matrix organiser. All matrix members to whom this certificate applies must be reported in advance to the certification body in a site list. For more information, please refer to Part D of the VLOG Standard.

A free contract (Standard Usage Agreement) must be concluded between the standard provider VLOG and the company to be certified, which regulates the use of the VLOG "Ohne Gentechnik" production and testing standard. This contract, signed by both parties, will be presented by the company during the audit or sent to the responsible certification body. Please note that the standard usage agreement must be concluded in good time before the VLOG audit in order to obtain a VLOG ID, as the processing time can be up to two weeks. Only after the allocation of a VLOG ID can your certification body issue a VLOG certificate.

Please complete the contract in full and send it signed as a clearly legible and single PDF file to: info(at)ohnegentechnik(dot)org.
