UNION PAK CORP, a China‑based exporter specialized in plastic containers and related packaging, shows a robust, US‑focused trade pattern with over 300 shipments since 2021, averaging 8‑10 moves per month and total TEU between 5 and 20 per month, primarily loading from Yantian (CN) and discharging at Los Angeles, Long Beach, and Houston. Its top buyers—HYSTAR HOLDINGS LLC, IMCO LLC, and QUEKEN LINSY INC—receive regular volumes, indicating a reliable supply chain and strong demand for high‑grade plastics (HS 760200, 392220, 741021). For buyers, the company offers predictable lead times, consistent product quality, and the capacity to scale shipments quickly across major US ports. For customs brokers, documentation is steady, with recurring HS codes and a limited set of loading/unloading ports, facilitating efficient clearance and low variance in duty assessments, while the repeat use of standard containers streamlines inspection processes.
