We mainly produce the Citric acid monohydrate(CAM) Citric Acid anhydrous(CAA),band : TTCA ,ZHONGLIANG ,TAIHE ,ENSIGN,UNION,RZBC BRAND .LEMAN STAR and so on ,sodium benzoate,trisodium citrate / sodium citrate, potassium sorbate , xanthan gum,CMC, SMBS , STPP ,PA , magnesium sulfate ,Ferrous sulfate, Caustic soda flakes ,Caustic soda pearls , and PVC resin ,etc. our company ZHSH focus on chemicals and food additives .As PVC resin, we worked with famous brands include Zhongtai, Ergos, Beiyuan andDagu, Hygain etc. we export more than 5000 mt each year. It was awarded "observe contracts and keep promises enterprise".
1. Because we do not produce, the factory will not take us as competitors. It is very convenient for us to transfer goods, so that we have a detailed grasp of the real situation of each company, such as scale, such as technology, such as quality, etc. If you do this work by yourself, it may be difficult.
materials, and even to fly investigation to rest assured, If you are the owner and have to hire several people to do this work, it actually costs much more than giving us a little commission to centralize the procurement for you!
purchasing various products for many customers. We have our own analyst and testing system, which can guarantee the quality for you.
