AI-Powered supplier vetting

SummaryKingherbs Limited is identified as a factory and limited company supplying Saw Palmetto Extract. It operates more than 10 production lines, reports plant-extract output of 500 tons, maintains in-stock capacity, and serves domestic and multiple overseas markets. The supplier supports customization from samples and flexible customization, but reports no new products in the past year, no ODM service, and no SDK. It has participated in VITA FOODS EUROPE 2025 but has no overseas agents, branches, warehouses, or showrooms. Service-control documentation is incomplete: no written corrective-action or complaint-handling procedures or records were provided, and the quality-assurance status is unknown. Financial records are indicated for 2022–2024, but their results are not provided. The supplier passed neither a clearly stated audit outcome nor certification details in the available information; the audit result is recorded as 0 without an explained evaluation scale.

Supplier typeThe supplier is explicitly classified as a factory and a limited company, with no indication that it belongs to a larger company group. Its primary product is Saw Palmetto Extract, and the audited company is named Kingherbs Limited.

After-Sales capabilityThe supplier has participated in an offline trade show, but it has no overseas agents or branches, overseas warehouses, or overseas showrooms. More importantly, no written corrective and preventive action procedures or records and no written customer-complaint handling procedures or records were provided, limiting evidence of formal after-sales capability.

R&D capabilityThe supplier reports no new products during the past year, no ODM service, and no available SDK. These explicit limitations indicate weak evidence of ongoing product innovation or software-development support.

Production capacityThe supplier operates more than 10 production lines, reports plant-extract output of 500 tons, has in-stock capacity, and serves domestic and several international markets. It also states an off-peak lead time within 15 working days, although outsourcing procedures and manufacturing contracts are listed as unknown.

Customization capabilityThe supplier explicitly provides customization from samples and flexible customization. This supports a positive assessment for customer-specific product adaptation, although the same slice confirms that ODM service is not available.
