In health food contract manufacturing, "customer-supplied raw materials" refers to the practice of clients or brands providing their own ingredients or raw materials for the production of their products. Instead of relying on the contract manufacturer to source and supply all the necessary materials, the client takes responsibility for procuring and delivering specific ingredients to be used in the manufacturing process.

This arrangement allows clients to have greater control over the quality and source of their raw materials. They may choose to supply ingredients that align with their specific requirements, such as organic, sustainably sourced, or proprietary ingredients. By providing their own raw materials, clients can ensure the authenticity, traceability, and adherence to their desired standards for their health food products.
