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.

CertificationsThe supplier states that it holds export/import and hazardous-chemical sales licenses and reports ISO 9001 and GMP certification. These are explicit compliance and management-system credentials, although the provided information does not include certificate numbers, issuing bodies, or validity dates.

After-Sales capabilityThe company states that it provides customized solutions and service, communicates with customers about quality and application requirements, and supports chemical trade through testing, logistics, and auditing. These statements indicate service capability, but no specific warranty, complaint-handling, replacement, or response-time policy is provided.

R&D capabilityThe supplier describes itself as conducting manufacturing and R&D of fine chemicals and states that it built a new factory for new fine chemical materials. It also reports 11–20 years of R&D-engineer experience and an objective of developing flexible manufacturing methods and customized solutions, providing explicit but largely self-reported evidence of innovation capability.

Production capacityThe supplier reports four production lines and annual capacities of 600 tons for carbohydrazide, 100 tons for O-phthalaldehyde, and 100 tons for sodium tetraphenylboron. It also states order fulfillment within 15 working days in both peak and off-peak seasons, supporting a positive assessment of documented production capacity and delivery readiness.

Customization capabilityThe company explicitly offers customized solutions and services, seeks customer quality and application requirements, and provides chemical-trade support covering purchasing, testing, logistics, and auditing. The evidence supports customization capability, although no specific examples of customized products or completed projects are supplied.
