The key raw materials of NGC Marine are consistently supplied by strategic cooperative suppliers under long-term stable arrangements, covering critical categories such as large steel forgings and various copper castings etc. We have established stringent selection criteria and comprehensive control standards for suppliers, involving oversight from raw material formulation to production processes, coupling with multiple quality inspection stages to ensure stable product quality. At the same time, long-term strategic partnerships significantly reduce intermediate costs, and a joint production scheduling mechanism enables precise control over delivery timelines. This "stable supply + full-process control" model grants the company's triple advantages in raw materials to get better price, quality, and delivery time, laying a solid foundation for the competitiveness of downstream products.
