AI-Powered supplier vetting

SummaryShandong Xinhongyun New Material Technology Co., Ltd. is identified as a Chinese trading company established in 2020 with 10 employees. It offers polyimide film, PMDA, 1,2,4,5-tetramethylbenzene, ODA, mixed aromatics, and TOPM. Reported annual productivity includes 200 tons of polyimide film and 3,200 tons of PMDA, while 41%–50% of sales are stated to come from exports. The supplier reports self-operated import and export rights, ISO 9001:2015 and ISO 14001:2015 certifications, a professional production, quality-control, and sales team, and business coverage across multiple countries. However, most information concerning outsourcing procedures, contracts, inventory, overseas services, R&D, customization, traceability, sustainability, and customer references is marked unknown. An SGS audit is recorded, but its evaluation result is listed as 0 and the report validity ended on 2025-07-07.

Supplier typeThe supplier is explicitly classified as a Trading Company, with its registered company name, Chinese origin, Shandong location, 2020 establishment date, and 10 employees also provided. This confirms the business type but does not establish that it directly manufactures all listed products.

CertificationsThe supplier reports holding ISO 9001:2015 and ISO 14001:2015 management-system certificates. These explicitly support certification holding, although the slices do not provide certificate numbers, scope, or current validity dates.

After-Sales capabilityThe supplier states that it has a professional production team, QC team, sales personnel, and can provide after-sales service. However, overseas-agent or branch capability and other service infrastructure are marked unknown, so the evidence supports a stated service offering but not broad or verified after-sales coverage.

Production capacityThe supplier reports annual productivity of 200 tons of polyimide film and 3,200 tons of PMDA, and identifies these products among its offerings. It is classified as a trading company, while the SGS audit evaluation result is listed as 0 and the audit report expired on 2025-07-07; therefore, capacity is documented, but current production capability is not fully verified.
