AI-Powered supplier vetting

SummaryChangsha Rokey Biotechnology Co., Ltd. is a China-based agriculture and food supplier established in 2013, focused on plant extracts, fruit and vegetable powders, chemicals, food additives, and herb extracts. It reports ISO 9001 certification, in-stock service capability, and lead times within 15 working days in both peak and off-season periods. Customization is available, including full, minor, and flexible customization. However, the evidence also shows no overseas warehouse, showroom, agent, or branch capability; no overseas service countries; no ODM or popular-brand OEM service; no new products in the past year; and limited formal quality and supplier-management documentation. Financial information is inconsistent across the provided periods, limiting a firm credibility assessment. No customer cases are provided.

Supplier typeThe supplier is described as Changsha Rokey Biotechnology Co., Ltd., a high-tech company established in 2013 that conducts R&D, production, and sales of plant extracts and fruit and vegetable powders. Its listed commercial focus is Agriculture & Food, with related chemicals, food additives, and herb extracts.

CertificationsThe supplier reports ISO 9001 certification of its management system. This is explicit evidence of holding a recognized quality-management certification, although the slices do not provide certificate scope, validity dates, or verification details.

After-Sales capabilityThe supplier has in-stock service capability and accepts multiple service quotation and payment terms, with stated lead times within 15 working days in both peak and off-season. However, it has no overseas warehouse, showroom, agent, or branch capability, no overseas service countries, and lacks written complaint-handling and corrective-action procedures or records.

R&D capabilityThe supplier reports fewer than five years of total R&D engineer experience, no available SDK, no new products in the past year, and no ODM service. Its stated customization services indicate some development support, but the evidence does not demonstrate strong ongoing innovation output.

Customization capabilityThe supplier explicitly offers full customization, minor customization, and flexible customization through its R&D capability. This supports a positive assessment of product customization, although the slices do not specify technical scope, development timelines, or completed customized projects.
