AI-Powered supplier vetting

SummaryQingdao Vital Nutraceutical Ingredients Bioscience Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory. It focuses on natural plant extracts, nutraceuticals, and OEM services, with products including garlic, mushroom, red yeast rice, and other extracts. The supplier reports ISO 9001 and GMP certifications, two production lines, fewer than five R&D engineers, and fewer than five quality-control staff. It claims experienced workers, professional technicians, technical after-sales support, abundant stock, and on-time guarantees, but these claims are not independently substantiated in the provided information. The company reports 90% export sales and self-operated import/export rights, with exports beginning in 2016. Limited transaction records identify buyers in Brazil and Ukraine. Financial credibility, customization strength, and the scale of customer relationships cannot be firmly assessed from the available evidence.

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory. Its stated activities include natural extract and nutraceutical supply, OEM services, and international trade, supported by self-operated import/export rights and a reported 90% export-sales share.

CertificationsThe supplier reports holding ISO 9001 and GMP management-system certifications. These are explicit certifications relevant to quality management and nutraceutical or health-product manufacturing, although no certificate scope or validity details are provided.

After-Sales capabilityThe company description explicitly claims technical after-sales support and a focus on satisfying customer requirements. However, no service team size, response standard, warranty terms, or documented service cases are provided.

R&D capabilityThe supplier states that it conducts R&D on natural extraction and supplies innovative natural plant extracts, while also reporting fewer than five R&D engineers. This supports the existence of an R&D function, but the limited staffing data and absence of patents, new-product records, or R&D outcomes prevent a stronger assessment.

Production capacityThe supplier is identified as a manufacturer/factory and reports two production lines, abundant stock, professional technicians, and on-time supply assurances. It also reports fewer than five quality-control staff, but the provided data does not specify capacity, facility scale, or throughput in non-financial terms.

Customization capabilityThe supplier explicitly offers OEM services, which is direct evidence of a customization-related capability for its natural extracts and nutraceutical products. No details are given on formulation development, minimum order requirements, packaging options, or customization scope.

Client casesTrade records identify one buyer in Brazil and one buyer in Ukraine, with the Ukrainian buyer appearing in two records. These records demonstrate some documented buyer activity, but the small number of transactions and absence of product, duration, repeat-order, or performance details limit the strength of the customer-case evidence.
