Yuansen New Precision Machinery (exporter of precision machine components) shows a sporadic but targeted US West Coast footprint, primarily using Yantian and Hong Kong loading ports to ship to Los Angeles and Long Beach. Over the past three years it completed only eight shipments, with the largest (7.2 t, 1.5 TEU) in Oct 2021 to Mottrol International Inc for HS 851490 electrical parts, and recurring smaller loads (≈0.4‑0.8 t) to KMP USA Ltd for HS 930320 machinery accessories such as pumps, coolers and fuel‑related items. The limited frequency suggests a niche supplier rather than a high‑volume partner, yet its consistent use of standard HS codes and repeat buyer relationships indicate reliable documentation and predictable routing. For buyers, Yuansen offers specialized parts with proven compliance for US entry, albeit with limited scalability; securing longer‑term contracts could unlock steadier supply. Customs brokers benefit from the clear port‑to‑port pattern, stable HS classifications and a modest TEU profile, facilitating efficient clearance and lower risk of customs delays.
