AI-Powered supplier vetting

SummaryJinan Finer Chemical Co., Ltd. is identified as a Chinese manufacturer/factory and limited company producing chemical intermediates, pharmaceutical intermediates, and fine chemicals. It reports ISO 9001 and GMP certifications, four production lines, stated annual capacities of 600 tons for carbohydrazide and 100 tons each for O-phthalaldehyde and sodium tetraphenylboron, and delivery within 15 working days in both peak and off-peak seasons. The supplier claims export/import and hazardous-chemical sales licenses, serves multiple global regions, and offers customized solutions and chemical-trade support including testing, logistics, and auditing. Evidence of innovation exists through R&D activities and experienced R&D engineers, while customer-case evidence is limited to one named buyer associated with one recorded product and transaction. Financial credibility cannot be reliably assessed from the provided information.

Supplier typeThe supplier is explicitly described as a factory and Manufacturer/Factory, with a limited-company structure and stated manufacturing and R&D focus in chemical intermediates, pharmaceutical intermediates, and fine chemicals. This directly supports classification as a manufacturer rather than only a trading intermediary.
