Suzhou TreeUp Chemical Co., Ltd. was established in 2013 as a specialist distributor and technical partner for polyurethane base raw materials. Headquartered in Suzhou Industrial Park and holding our own import-export licence, we handle export clearance, inspection and documentation in-house, with Shanghai and Ningbo ports right on our doorstep.
Thirteen years on, we still only trade chemicals we understand. Stable direct-purchase channels are in place with Wanhua Chemical, Cangzhou Dahua, Longhua New Material, BASF, Covestro and Huntsman, covering TDI, PPG, POP, MDI as well as silicones, catalysts, flame retardants and pigments.
With four bonded warehouses and dangerous goods export licensing, we hold roughly 8,000 MT of safety stock and serve foam, elastomer, insulation and CASE customers in over 40 countries. We believe a distributor should do more than move cargo — it should help customers choose right, avoid detours and bring cost down.
