About US

Hainan Sincere Industries Co., Ltd. is a professional fine chemicals supplier and chemical sourcing partner from China. Founded on more than 25 years of chemical industry experience, we support global customers with reliable supply of pharmaceutical intermediates, agrochemical intermediates, electronic chemicals, ionic liquids ,cosmetic and personal care raw materials, water treatment agents and chelating agents, specialty chemicals and related products.

We started in Shijiazhuang, a major hub for the chemical industry in China. This location gave us firsthand, long-term exposure to the realities of the sector—spanning factory production, product development, quality control, supplier partnerships, and export logistics, as well as the critical need for consistent product quality demanded by clients.

Over the past 25 years, we have navigated various business models, including operating our own manufacturing facilities, acting as exclusive agents for factories, engaging in collaborative production, and partnering with universities, research institutes, and technical teams for custom R&D.

We have a research and development team composed of chemical experts and industry elites, and maintain long-term close cooperation with well-known domestic universities, provincial and national scientific research institutes, and have ensured advanced product technology, stable quality and price advantages in many ways. We have established an ISO 9001 system and have now formed a professional chemical raw material supply enterprise combining science, industry and trade, and combining domestic and foreign trade, and are committed to providing customers with high-quality products and innovative solutions.

These experiences have provided us with more than just product resources; they have given us a profound understanding of the entire chemical supply chain.

We know which factories are reliable and which products are worthy of long-term partnership. We understand the documentation and quality standards that truly matter to overseas clients, and we are well aware of the challenges they face when seeking suppliers in China.

Our Founding Vision

Throughout our 25-year history, we have worked with a vast number of clients from diverse regions. We have witnessed the hurdles overseas clients encounter during the procurement process: it is rarely a lack of willingness to source from China, but rather the difficulty of finding truly reliable suppliers.

Some clients struggle with communication barriers that prevent the accurate conveyance of technical requirements; others find it hard to verify a supplier’s legitimacy and reliability. Some have received products with inconsistent quality or failed to obtain complete technical data and export documentation. Others have compared multiple factories without being able to determine which ones possess genuine long-term delivery capabilities, or have suffered from unsatisfactory—or even failed—partnerships due to information asymmetry.

As our relationships deepened, an increasing number of clients began entrusting us to find suitable Chinese suppliers, evaluate products, coordinate technical communications, oversee production, and resolve various procurement issues.

The trust placed in us by these clients made us realize that what overseas clients truly need is not merely a product supplier, but a long-term partner who understands China’s chemical industry, connects them with reliable resources, and mitigates procurement risks.
Because we have long positioned ourselves at the heart of the chemical supply chain—bridging the gap between manufacturers and end-users—we have a clear understanding of the pain points faced by overseas clients.

This is the foundation upon which Hainan Sincere Industries was established.
