SHENZHEN BULL NEW MATERIAL TECHNOLOGY, Exporter of plastic films, stretch‑tape, packing and related polymer products, shows a focused supply pattern dominated by the US West‑Coast market, chiefly loading from Yantian (and occasional Shekou) and unloading at Los Angeles, Long Beach, with occasional New York entries. Over the past 24 months it completed roughly 120 shipments (≈ 500 k kg total) for a core buyer – Universal Elastic & Garment Supply – accounting for 60‑70 % of volume, while secondary buyers such as Amazon Services, High Tech Logistics and LENA PACKAGING contribute smaller but regular loads. The HS‑code profile is highly concentrated on 392010 (plastic sheets/films) with occasional 851993 (electrical accessories), indicating a stable product classification that eases customs coding. For buyers, the company offers reliable, high‑frequency deliveries of standardized film‑based materials, supporting steady supply chains and predictable lead‑times. For customs brokers, the consistent use of a narrow HS‑code set, recurring ports, and regular TEU sizing (mostly 2‑8 TEU) facilitate efficient documentation and clearance, reducing deviation risks and expediting border processing.
