User’evaluation of us

"Chem-ios is my partner for years. Met at 2014 Shanghai CPHI Expo. Not interested then as had stable supplier. In Sep 2016, original supplier couldn't guarantee quality and delivery. Thought of Zhai and his company first. So far, have stable business relationship and good personal friendship."

Jasmine Hook

" In years of sourcing from China, first found working with Sincere Chemical great. They help in production, delivery and tech, saving time. When first asking Zhai for optical brightener quote, got detailed one with prices, trade details, company info, R&D and production capacity, packaging and raw material control."

Michael Cooper

" Hi, I'm Kim, Zhai's partner. Don't like him much (as he never gives more for my prices, haha), but still write customer feedback. Zhai's emails help me understand product and industry. Satisfied with his work ethic. He provides quotes and helps with work details, so I can focus on other things. He's the best supplier for me."
