LONG WELL ELECTRONICS DONG GUANG CO LTD, an exporter of electronic components (HS 851640), primarily ships medium‑size loads (≈4 t, 1.5 TEU) from Yantian, China to Los Angeles, serving high‑value buyers such as Speedo USA Inc.; the singular recorded shipment in September 2022 indicates a low frequency but a focused, high‑weight transaction pattern, suggesting a niche‑market, possibly OEM‑level supply chain. For prospective buyers, the company demonstrates reliable weight consistency and a clear product portfolio centered on electronic accessories (e.g., masks, seals, travel‑related items), signaling potential for stable supply once a regular cadence is established. For customs brokers, the documentation is straightforward: a single HS code, consistent port of loading and unloading, and predictable routing, which translates to efficient clearance and minimal classification risk. Engaging LONG WELL could provide buyers with a dedicated source for specialized electronics, while brokers can expect streamlined customs processing due to the company’s limited yet well‑defined shipment profile.
