ZHONGSU NEW MATERIALS TECHNOLOGY, an exporting supplier of barrier film and flexible packaging products, consistently ships from Ningbo (Port 57020) to major U.S. West Coast ports—Portland, Long Beach, Seattle and Los Angeles—primarily serving FLAIR FLEXIBLE PACKAGING (USA and Canada) and ACE PACKAGING INC. Monthly shipment frequency ranges from 1 to 4 containers, with peak volumes in Oct‑2022 (81.8 t, 7.5 TEU) and Aug‑2022 (68.8 t, 6.5 TEU), all under HS Code 370220 (plastic films) and occasional 852729/392010 entries, indicating a focused product portfolio and stable demand. For buyers, the firm offers reliable, repeatable supply of high‑volume barrier films, demonstrated by recurring orders from the same key accounts and predictable loading ports. For customs brokers, the company’s documentation is highly consistent: recurring HS codes, unchanged loading port, and a limited set of unloading ports simplify classification and clearance, while the regular TEU sizes support efficient routing and risk assessment.
