ZHEJIANG SLION FLUID CONTROL CO LT, an exporter of hydraulic valves and related parts (HS 848190), shows a steady supply pattern focused on North‑American markets, primarily serving Culligan International and National Fire Equipment Ltd; these two buyers account for over 80% of its shipments. Monthly export volumes range from 1‑2 container loads, averaging 300‑2,000 kg, with loading ports chiefly Shanghai (57035) and Ningpo (57020) and unloading consistently at Tacoma, WA and Seattle, WA, indicating a predictable West‑Coast routing. For buyers, the company offers reliable product availability, a narrow yet focused product portfolio, and repeat order sizes that signal stable demand. For customs brokers, documentation is uniform – same HS code, consistent carrier filings, and limited port diversity – which facilitates efficient clearance and low risk of classification disputes. The firm’s regular cadence and clear trade lanes make it a low‑risk partner for both procurement planning and customs compliance.
