Inner Mongolia Yizhou Trading Co., Ltd. exports dense and light soda ash (Na₂CO₃) and food, feed and industrial sodium bicarbonate (NaHCO₃). Dense and light each have their own URL. The PDFs in /docs are the current plant sheets — lot COA governs the shipment.
Dense and light soda ash share one CAS and one chemistry — sodium carbonate, the name buyers also put next to soda ash on a PO. Food, feed and industrial bicarbonate share the other. Pick the grade your QA file names; packing and documents follow that grade.
