TAIWAN HOPAX CHEMICALS MFG CO LTD, Exporter of specialty chemicals (primarily buffers, pH reagents and laboratory additives), ships 7‑14 shipments per month from Kaohsiung (and occasional Chi‑Lung or Shanghai loads) to U.S. West‑Coast ports (Los Angeles, Oakland, Long Beach) and East‑Coast hubs (New York/NJ, Norfolk). Core buyers include Life Technologies, Walmart, Hyclone Laboratories and major biotech firms, indicating steady demand for high‑purity reagents and a diversified customer base. For buyers, Hopax offers reliable supply volumes (averaging 15‑20 TEU/month), consistent product lines and repeat orders that signal growth potential in the life‑science supply chain. For customs brokers, the company uses a narrow set of HS codes (mainly 382200, 520300, 630710), files uniform documentation, and follows predictable routing patterns, resulting in low clearance delays and high customs efficiency. This combination of dependable logistics, focused product portfolio and disciplined customs compliance makes Hopax a trustworthy partner for both commercial purchasers and clearance specialists.
