AI-Powered supplier vetting

SummaryQingdao Vista Bio. Tech. Co., Ltd is a China-based limited company identified as both a trading company and manufacturer/factory, operating in health, medicine, agriculture, and food. It holds ISO 9001 and HACCP certifications and reports a valid import/export license. The supplier demonstrates customization and product development capabilities, including sample-, design-, and flexible customization, with one R&D engineer and new products launched in the past year. Its stated quality controls are based on GMP standards and internal procedures. Evidence indicates export experience across multiple regions and a reported off-peak lead time within 15 workdays. However, the available information does not establish after-sales service capability, customer cases, raw-material traceability, environmental compliance status, or sufficient financial details for a credibility assessment. The supplier also does not provide 3D software design services or an SDK.

Supplier typeThe supplier is identified as a trading company, while another record classifies it as both a trading company and manufacturer/factory. It is a limited company based in Qingdao, China, with health, medicine, agriculture, and food activities; therefore, its exact operating model includes both commercial trading and stated manufacturing activity.

CertificationsThe supplier reports ISO 9001 and HACCP certifications. It also states that, beyond GMP standards, it maintains an internal quality control system based on R&D and production experience, supporting a documented quality-management position.

R&D capabilityThe supplier is explicitly identified as a professional technical supplier, reports R&D-based production experience, has one R&D engineer, and launched new products in the past year. However, it has no available SDK and does not provide 3D software design services; overall innovation capability is supported for product development but not for software-oriented engineering.

It also states an off-peak lead time within 15 workdays and exports to multiple regions, providing evidence of operational production capability.

Customization capabilityThe supplier explicitly offers customization from samples, flexible customization, and customization from designs, while its company description states that it supplies botanical extracts according to customers' customized demands. This directly supports a broad product-customization capability, though not 3D software design.
