WAVE CYBER ENVIRONMENTAL PROTECTION, an exporter specializing in FRP water‑tanks, accessories and membrane components, consistently supplies large‑volume buyers—most notably Culligan International, which accounts for 45‑55 % of monthly shipments and over 90 % of weight—across the U.S. West Coast (Tacoma, Los Angeles, Long Beach) from its primary Shanghai loading port. Monthly shipments range from 7 to 20 trips, averaging 20‑30 TEU and 200‑450 t, with HS Code 860610 (water tanks) used in >80 % of entries, indicating stable product classification. For buyers, this signals a reliable, high‑capacity source of essential water‑treatment hardware with predictable delivery schedules and a diversified secondary buyer base (Puretec, Veolia, Franklin Water Treatment). For customs brokers, the repetitive routing, uniform HS coding and consistent documentation streamline clearance, reducing inspection risk and enabling efficient customs planning for repeat imports from China to the U.S. ports.
