"Hello, we are a large distributor in Gujarat. We supply many textile mills for desizing. Your quality is top-notch, especially the solubility which our clients like very much. In India, price competition is fierce, so I always negotiate hard, but I appreciate that you never sacrifice quality for cost.

We plan to expand to Sodium Persulfate next month."

"We are a factory in Bac Ninh making PCB boards. We switched to your Sodium Persulfate because our previous supplier had inconsistent purity. Since then, our etching defect rate has decreased. For us, 'just-in-time' delivery is most important because our warehouse is small. Your logistics team is very efficient and communication is clear. My boss is satisfied with the cost-performance ratio. If you provide more technical videos for worker safety training, it would be even better. We will continue ordering for our new production line."

I suggest slightly improving the bag lining for extreme Canadian temperature transitions. Overall, you are a top-tier supplier for our environmental projects."
