​​Cummins Inc. values global supplier partners who share our commitment to quality and value, but who operate under a philosophy that focuses on Excellence – always delivering superior results.

To support that philosophy, Cummins has a Supplier Handbook – Customer Specific Requirements specifically for its supply base worldwide. The supplier handbook outlines the minimum requirements that a supplier must meet to do business with Cummins. The handbook applies to all suppliers that produce goods or provide services for Cummins and any of its subsidiaries, joint ventures, divisions, or affiliates.

The Cummins Inc.-Customer Specific Requirements is aligned with ISO9001:2015 and IATF 16949:2016. All Suppliers to Cummins Inc. must meet the requirements of the Cummins Inc.- Supplier Handbook (Customer Specific Requirements).


Cummins Inc. separates the products and services purchased from suppliers into two categories Indirect and Direct:

Indirect: defined as all services and any products that are not assembled and shipped to an end customer (including tooling, chemicals, machinery, computers, gauges, packaging, training, real estate, and prototypes, etc.)

Direct: defined as all products that are manufactured and assembled into a product that is directly shipped to a customer (includes engine components, filters, turbochargers, generators, alternators, etc.)


Indirect suppliers are required to accept and follow the Cummins Inc. Indirect Supplier Handbook – Customer Specific Requirements.
