USTC DYNAPLUG is an importer specializing in plastic packaging and small component products such as blister packs, PVC caps, silicone parts and related accessories, primarily sourced from Chinese manufacturers in Yantian and delivered to West Coast US ports (Oakland and Los Angeles). Over the past three years the company has executed roughly 15 shipments, averaging 1–2 TEU per load and total weights between 300 kg and 1.9 t, with a strong concentration on HS 391000 (plastic articles) and HS 392620 (PVC articles). The dominant supplier is Eastern Rich Industries Ltd, complemented by occasional partners such as Fun Home Industrial and Dong Guan Richtek, indicating both reliability and supplier diversification. For customs brokers the filing pattern is highly predictable: consistent ports, stable HS codes, and modest cargo volumes support efficient clearance and low risk of documentation discrepancies, making USTC DYNAPLUG a dependable trading counterpart for suppliers seeking reliable US market access.
