AI-Powered supplier vetting

SummaryNanjing NutriHerb BioTech Co., Ltd. is identified across the records as a China-based limited company operating in plant extracts, pharmaceutical intermediates, cosmetics, agriculture, food, and related trading activities. The supplier has documented procedures and records for corrective/preventive actions and customer complaints, and holds an ISO9001:2015 certificate. Production information lists capacities for four products, with 11–20 quality-control staff and 6–10 years of combined R&D-engineer experience. However, the records state that no SDK is available, no new products were launched in the past year, quality assurance and traceability statuses are unknown, and quality-control test equipment is recorded as zero. Financial records provide years rather than assessable financial results, so financial credibility cannot be judged. No customer cases are provided.

Supplier typeThe supplier is recorded as a China-based limited company, with records describing it both as a trading company and as a manufacturer/factory. Its stated activities cover plant extracts, pharmaceutical intermediates, biotechnology R&D, cosmetics, daily necessities, and import/export business.

CertificationsThe supplier holds an ISO9001:2015 certificate. A BV audit record is also provided, with a report period from 2025-01-08 to 2026-01-07, although the recorded audit evaluation result is 0 and no interpretation of that result is supplied.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and for handling customer complaints. This provides explicit evidence of documented service-response processes.

R&D capabilityThe company focuses on innovation in herbal extracts and reports 6–10 years of total R&D-engineer experience. However, it has no available SDK and launched no new products in the past year, indicating limitations in the specifically recorded innovation outputs and technical-support offering.

Customization capabilityThe supplier explicitly reports a design-services capability limited to minor customization. This confirms some customization availability but does not evidence broad or advanced customization capability.
