Shijiazhuang Bangshang Trade Co., Ltd.

Shijiazhuang Bangshang Trade Co., Ltd. operates out of Shijiazhuang in China and currently lists nine distinct products. The catalogue spans gypsum processing equipment, chemicals such as caustic soda and acid dyes, and specialty additives like hydroxypropyl methylcellulose (HPMC). Its top categories include Gypsum, Chemicals & Allied Products, Caustic Soda, Construction Materials, and Ceramic Tiles. The company focuses on supplying production lines for gypsum cornice, gypsum board (both paper‑faced and non‑paper‑faced), and gypsum powder. It also offers raw chemical items, namely caustic soda, Acid Black I, and Acid Black dye.

The listed gypsum lines cover cornice production (HS 8474.80), powder production (HS 8474.20) and both paper‑faced and non‑paper‑faced board lines (HS 8479.89). In industry, gypsum board thickness typically ranges from 9 mm to 15 mm, density 800‑950 kg/m³, and board cores are required to contain at least 95 % calcium sulfate dihydrate for structural stability. The chemical segment includes caustic soda, which is usually supplied at 99 % NaOH purity, and sodium‑based acid dyes (Acid Black I and Acid Black) that conform to colour strength specifications such as C.I. 77005. HPMC products for wall putty and tile filler fall under HS 3912.39; buyers normally specify viscosity grades between 5 cPs and 30 cPs at 25 °C and a moisture content below 12 %.
