WOO SING INDUSTRIAL CO LTD, an exporting supplier of lifting hardware and material‑handling kits (chains, hoists, clamps, pallets and related accessories), has shown a highly repeatable trade pattern centered on the US market, especially servicing Tiger Lifting North America Inc with  ≈ 70 % of its shipments and a smaller share to other North‑American buyers such as WFI INC and Hostar Inc. Monthly exports from 2024‑2025 average 1‑3 container loads (1‑4.5 TEU) per shipment, weighing 12‑25 tonnes, and follow a stable routing: loading ports in Taiwan (Taipei, Kaohsiung), South Korea (Pusan) and China (Ningpo) to US unloading ports primarily New Orleans, LA and occasionally Los Angeles or Houston. HS‑code usage is concentrated on 842519 (lifting equipment) and related codes (842570, 846719), indicating consistent product classification. For buyers, the firm offers reliable volume, predictable lead‑times and a focused product portfolio that supports large‑scale lifting projects. Customs brokers benefit from the regular documentation, stable HS‑code assignments and a limited set of origin‑destination pairs, which streamline clearance, reduce inspection variance and enhance compliance predictability.
