FOREVER NINGBO MACHINE WANJIN, a Shanghai‑based exporter of extrusion machine parts (HS 851590), recorded a single May 2025 shipment of 153 kg (1 TEU) to Los Angeles, serving United Feed Screws as its top buyer. For prospective buyers, the company demonstrates niche expertise in feed‑equipment components with a clear product focus and a stable Shanghai‑Los Angeles routing, suggesting reliable lead times despite its currently low shipment frequency. For customs brokers, the trade pattern is straightforward: consistent use of HS 851590, a single loading port (Shanghai) and unloading port (Los Angeles), and uniform documentation across this route, which facilitates predictable clearance and lowers risk of compliance issues. Monitoring future shipment volume will be key to gauging growth potential and long‑term supply reliability.
