Despite global trade fluctuations, Hilight Chemical has leveraged its "Jinan HQ + Dongying Plant" dual-center model to shorten lead times. Our export business has seen robust growth this year, particularly in Southeast Asia and South Africa.Through deep cooperation with carriers like COSCO and Maersk, we secure stable shipping space even during peak seasons. With ready-to-ship stock of various DADMAC and PolyDADMAC grades, we can arrange container loading within 72 hours, significantly improving efficiency for our clients.
In Q4 2023, Hailai Chemical’s flagship products excelled in their annual audit by SGS. The reports confirm that our DADMAC and PolyDADMAC and Polyamine series fully comply with EU REACH (SVHC) regulations and meet the US ANSI/NSF standards for drinking water chemicals.Securing these international "passports" has allowed us to establish long-term partnerships with major water utility groups in the US, Australia, and Turkey. We provide not just products, but global compliance and professional technical support.
