Introduction to Customer Specific Requirements (CSR) according to IATF

The organization which is implementing quality management (QMS) system according to IATF 16949 should be aware that, in addition to the fulfillment of this technical specification requirements, must also meet the customer specific requirements.

By this, the manufacturer’s customers (eg Stellantis-FCA, Ford) have an influence on its quality management system. CSRs are a part of the Customer Requirement – see the figure below.

They are issued by individual clients as additions specifying the requirements of IATF 16949, and their current versions are always available at

The CSRs themselves (which are an extension of the IATF requirements) are differently specified for each of the automotive industry customers and can be distinguished in terms of the specificity for:

  • product / service
  • project
  • supplier

In accordance with the requirements of 4.3.2, they should be assessed and included in the scope of the organization’s quality management system. This assessment should then be continued during audits of the quality management system as required by

Why using actual Customer Specific Requirements is so crucial for sub-suppliers

Compliance with CSRs is crucial for component producers to meet automotive standards and regulations. CSRs encompass specific guidelines and specifications set forth by customers, which ensure the components’ quality, performance, and safety. Adhering to these requirements helps producers demonstrate their commitment to compliance, reducing the risk of recalls, legal liabilities, and reputational damage.

CSRs play also a vital role in customer satisfaction. Sub-suppliers must understand and align their Quality Management System with the CSRs provided by their customers. By delivering components that meet or exceed these requirements, producers enhance customer confidence, satisfaction, and loyalty.

We have to remember, that following actual documents is crucial for fostering long-term business relationships with suppliers and OEMs. Customers have specific expectations and demand that components meet their unique specifications. By consistently meeting CSRs, Tier 2 producers demonstrate their ability to deliver high-quality components and become reliable partners in the supply chain. This enhances trust, strengthens collaboration, and opens doors to future business opportunities.
