NINGBO YEONG SHANG CASTING IRON CO, an exporter specializing in ductile iron castings (HS 7307 19), consistently ships from Ningbo (Port 57020) to major US gateways such as Long Beach, Seattle, Tacoma, Los Angeles and New York. Over the past three years the company averages 1‑6 TEU per month, with shipment weights ranging from 2 t to 160 t, and has built a repeat buyer base dominated by Milacron subsidiaries, indicating dependable demand and strong contractual ties. For prospective buyers, YEONG SHANG offers a reliable supply chain, steady volumes, and a focused product portfolio that supports injection‑molding and plastics equipment manufacturers. For customs brokers, the firm’s documentation is highly predictable: a single HS code, a sole loading port, and recurring destination ports simplify classification, duty calculation and risk assessment, while the regular cadence of filings supports efficient clearance and minimal inspection delays. This operational consistency makes YEONG SHANG a low‑risk partner for both commercial sourcing and customs facilitation.
