The control on zinc sulfate monohydrate heavy metal content get further improved

 To some small-scale factories, they has to stop the production of zinc sulfate in the heated summer. Maybe,there’s no exception this year too. As to Rech Chemical Co. Ltd, we still normally keep balance in production and sales in the summer for we had the best process of production zinc sulfate.

Every year, we received a sampling inspection report from a governmental third party testing center, which reports the important test indicators such as zinc sulfate's heavy metals content  lead, arsenic, cadmium content is 0.50 PPM, 0.01 PPM, 0.55 PPM, which not only much lower than national standard (national standard for lead, arsenic, cadmium: 10 PPM, 5 PPM, 10 PPM), but also improved forward much compared with our previous internal control indicators. 

Rech Chemical Co. Ltd’s product could show excellent quality in the test results, due to our severe purchasing standards on raw materials and constant seeking for technology improvement. If customers want to do SGS before shipment we can also arrange it. The original test report on zinc sulfate’s heavy metals content released as follows:
