NINGBO SHIELD SEALING CO LTD, an Exporter of sealing‑gasket and graphite‑based products, consistently ships from its home port Ningbo (57020 CN) to U.S. West Coast gateways—Los Angeles, Long Beach and Tacoma—and occasionally to Houston and Newark, using HS 380190 as the dominant tariff code. Over the past 24 months it averaged 3‑5 shipments per month (≈7‑12 tonnes each) with a stable TEU footprint (≈3‑5 TEU), reflecting dependable container utilization. Key buyers such as MINERAL SEAL CORP, EGC ENTERPRISES, O G SUPPLY and QUEST GASKET show repeat orders, indicating strong demand for high‑quality gaskets and related components. For Buyers, the firm offers reliable supply, predictable lead‑times and a diversified product mix that can support scaling production lines. For Customs Brokers, the company’s uniform loading port, recurring HS‑code usage and consistent unloading ports simplify classification, duty assessment and clearance planning, minimizing inspection risk and enabling efficient routing. The steady shipment cadence and expanding buyer base suggest modest growth potential, making NINGBO SHIELD SEALING a trustworthy partner for procurement and a low‑complexity client for customs operations.
