AI-Powered supplier vetting

SummaryORIEN CHEMICAL CO., LTD. is a China-based limited company in Hangzhou, Zhejiang, described across the records as both a trading company and manufacturer/factory. It offers a broad portfolio of dyes, pigments, colorants, additives, and other chemicals, with 90% of total sales reportedly coming from exports and five years of exporting experience. ISO 9001 certification is stated, and the supplier also claims SGS verification, although the available records do not provide certificate details or validity information. The supplier reports sample-based, full, and flexible customization. Financial records are indicated for 2021–2023, but no financial figures or assessment results are provided. Service-control documentation is weak: supplier records lack approval signatures or dates, and complaint and corrective-action procedures have no written records. No OEM service for popular brands or available SDK is reported. Customer praise is claimed, but no named customer cases or verifiable references are supplied.

Supplier typeThe supplier is identified as a limited company from China, operating in Zhejiang, and is described as both a trading company and manufacturer/factory. Its stated business scope covers chemical raw materials and products, while its product scope includes multiple dye categories, organic pigments, solvents, and chemicals.

CertificationsISO 9001 certification is explicitly stated, and the company separately claims to be SGS verified. These statements provide positive certification evidence, although the slices do not include certificate numbers, dates, scopes, or verification details.

After-Sales capabilityThe supplier states that its products and services have been praised by customers, but its documented service controls are incomplete: approved-supplier records lack signatures or dates, and complaint-handling and corrective/preventive-action procedures have no written records. This is explicit evidence of a documentation deficiency in service management.

Production capacityThe supplier is identified as a manufacturer/factory and claims technically advanced manufacturing bases and rigorous quality control. It offers a broad range of dyes, pigments, colorants, additives, and chemicals, but the records do not provide production capacity, equipment details, factory scale, or output data.

Customization capabilityThe supplier explicitly reports customization from samples, full customization, and flexible customization. This directly supports the existence of multiple customization modes.
