What types of companies may apply for registration to ISO/TS 16949?

ISO/TS 16949 is intended for suppliers that make or fabricate production materials, production or service parts, or production part assemblies. ISO/TS 16949 also applies to specific service oriented suppliers - heat-treating, welding, painting, plating or other finishing services. The customers for these types of suppliers must be manufacturers of automobiles, trucks (heavy, medium and light duty), buses, or motorcycles. Any tier supplier to these manufacturers can adopt and apply the ISO/TS 16949 standard if they meet the described part production or services applicability requirements.
