Wuhan Changle Purification Engineering Technology Co Ltd, Exporter of water‑treatment and filtration equipment, has recorded modest but consistent overseas shipments, averaging one container (≈1 TEU, 7–8 t) per month in recent periods, primarily loaded in Shanghai and discharged in Charleston, SC, USA. Its top buyer, All Pro Coolers LLC, repeatedly imports items classified under HS 750522, suggesting a niche focus on metal‑based components such as doors, panels and related structures for cooling or treatment facilities. For Buyers, the firm offers a reliable, single‑container supply cadence with a clear product line tied to industrial cooling and water‑purification installations, indicating dependable fulfillment for projects requiring specialized metal assemblies. For Customs Brokers, filings are uniform, using the same HS code and routing each month, which streamlines documentation checks, reduces discrepancy risk, and supports predictable clearance timelines at both loading and destination ports. This stability makes the company a low‑risk partner for agents handling U.S. imports of water‑treatment hardware.
