Our seven evaluation criteria

The Group Procurement Division rates candidates based on each of these seven criteria: 

  • quality
  • cost and competitiveness
  • logistics
  • finance
  • management
  • product and/or project development
  • sustainable development

To be selected, you must earn the minimum score required for selected criteria and a minimum score for all of the criteria combined.

Continuing requirements

Once you’re selected, keep up the good work! The Group Procurement Division will continue to evaluate your performance under your contract and may reconsider your approved supplier status at any time.

Our quality requirements

To keep our operations and the French rail network safe, we constantly monitor the quality of the products and services we buy, so you must meet a certain number of requirements, as provided in our contracts.

Quality control

Under some contracts, our partner businesses must have a quality management system that complies with the NF EN ISO 9001 standard.

Quality requirements appear in our Quality Specifications.

SNCF Certificate of Excellence

If you become a regular supplier, we may issue an SNCF Certificate of Excellence to your company. This means that you are performing at a very high level and that all of the affected people at SNCF—buyers, specifiers, project leaders and more—are satisfied with every aspect of your service.

How to earn a Certificate of Excellence

Our Supplier Quality Division evaluates the effectiveness of your work and issues the certificate based on all of the sites that contributed to delivering your product.

For builders of rolling stock, certificates may be issued independently to each integrator site based on evaluations for the period under review.

Suppliers of engineering work and design studies

For suppliers of engineering works and design studies that exceed a specified value, quality surveillance includes an evaluation form to be completed by both parties at the end of the project.

This allows service providers to improve their performance and gives ISO 9000-certified suppliers a customer evaluation form.

Do you need to be a qualified supplier?

Our qualification process ensures that your company has the legal, financial, technical and organizational capacity to deliver a specific product or service.

For some products, services and engineering works, we require advance qualification. For others, we don’t. To find out whether your project requires qualification or not, see the instructions below. And at the bottom of this page, you’ll find links to all of our qualification documents, organized by industry.

SNCF qualification: How it works

Some products, services and engineering works require advance qualification, which involves three key steps:

  • you submit a qualification application to SNCF
  • SNCF processes the application in four months, dating from our receipt of the complete application
  • once qualification has been granted, we may withdraw it at any time if the basis for issuing it are no longer valid.

Your qualification application

Your qualification application allows us to determine whether you have the necessary legal, financial, professional and technical capabilities for the product(s) to be provided. The application consists of administrative information, a targeted product evaluation questionnaire, and related documentation.


Please remember that:

  • if you’re a subsidiary, you can’t rely on your parent company’s qualification. You must apply independently.
  • we issue invitations to tender to a limited number of companies, based on the specifications for each contract.

Purchases which do not require qualification

Our selection criteria are tailored to each purchasing project and are defined for each invitation to tender.

This ensures that the contract will be properly performed, without risk of default, and enables us to assess your company’s key capabilities:

  • administrative and legal
  • economic and financial (solvency, profitability)

We also use the selection criteria to assess your company’s technical capabilities, including:

  • whether your company holds a professional qualification certificate (such as Qualibat) or quality assurance certificate
  • whether your company has the necessary technical and human resources to ensure that you can meet quality requirements and deadlines
  • whether your company has relevant, up-to-date references for similar projects


SNCF solicits tenders from as many candidate companies as required by the nature of each contract. Responding to a notice in the Official Journal of the European Union does not guarantee that your company will be invited to tender.
