WHY THEY SAY TO US
Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.
In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!
Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
Sincere Chemical team visited our USA factory in the year of 2017. We think highly of cooperation with them. We thanked you for the past excellent orders and best product quality. We also talked about some new products for future orders. We will be still in strategic cooperation in the future and help each other.
I just got the product. The quality is awesome. I’m very happy. Hope to place soon a new order in your company. Also wish for our future business.
Sincere Chemical is a reliable and professional company. Not only on exporting but also their professional team service. Their team gave us so many suggestions for our new project. We are really satisfied with their awesome service and best product quality. Sincere-Chem’s vendor code is 51465768 in our cooperated vendor list system.
I have visited Sincere Chemical company in the year 2018. Their company can be considered as one of the most professional, customer-focused, and product quality-driven companies that I have worked with in recent years.
We are a pharmaceutical products manufacturer in Brazil. I’m happy to cooperate with Sincere Chemical especially cooperate with Peter. Peter is patient and friendly. I’m satisfied with his 24*7 hours service. We are not only cooperators but also best friends with each other.
Great service and very supportive. This is my first order and I feel fortunate to be with Peter and his company. Product received was the right good quality product, so my review is more related with the quality, service and shipment. Thank you for sending. next time I will order again. Good supplier...
