AI-Powered supplier vetting

SummaryXi'an Xinlu Biotechnology Co., Ltd. was established in 2015 and specializes in the R&D, production, processing, and sales of natural plant extracts and pharmaceutical intermediates. Its stated product range includes Matrine, Oxymatrine, Magnolol, Honokiol, Gentiopicroside, Cytisine, and other compounds. The supplier reports OEM service for well-known brands, in-stock capability, broad customization options, and export activity accounting for 51%–70% of total sales. However, it reports no available SDK, no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Quality-system evidence is weak: there are no written corrective-action or complaint-handling procedures, and quality-control testing equipment is reported as zero. Certification, raw-material traceability, environmental documentation, fire-drill practices, and manufacturing-contract status remain unverified.

Supplier typeThe supplier is a biotechnology company focused on the R&D, production, processing, and sales of natural plant extracts and pharmaceutical intermediates. Its permitted business scope also includes pre-packaged food, non-food health products, and import/export activities, indicating a manufacturer and trading-capable supplier rather than a purely service-based company.

After-Sales capabilityThe supplier reports in-stock service capability and accepts FOB, CIF, CFR, and EXW quotation terms. Nevertheless, it has no overseas warehouse, showroom, agents, or branches, and reports no written procedures or records for customer complaint handling or corrective and preventive actions, which is a stated service-process deficiency.

R&D capabilityThe supplier describes itself as having R&D capability, offers customized product development, and can cooperate with customers to develop new products. However, it explicitly reports no available SDK, so software-development integration capability is absent; overall innovation strength is only partially evidenced.

Production capacityThe supplier describes production and processing capabilities, lists multiple plant-derived compounds, operates from a site of about 10,000 square meters, and reports inventory capability. However, manufacturing-contract status is unknown and the quality-control section reports zero testing equipment, creating a material concern about documented production-control capability.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also states that it can produce according to customer needs and cooperate in developing new products, providing direct evidence of broad customization capability.
