AI-Powered supplier vetting

SummaryQingdao Norson Sewage Environment Technology Co., Ltd. is identified as a Chinese manufacturer/factory of sewage and water-treatment equipment, with operations in Qingdao, Shandong. The supplier reports ISO 9001 certification, 5 production lines, 6–10 quality-control staff, and 6–10 years of total R&D-engineer experience. It has exported since 2018, maintains self-operated import/export rights, and serves multiple global regions. The supplier states that it provides technical solutions and after-sales support, but the investigation data does not establish the scope or service performance. SGS audit information is present for a period from October 20, 2025 to October 19, 2026, but the stated evaluation result is not interpretable from the provided value. Outsourcing, inventory, overseas warehouse/showroom, OEM/ODM, SDK, raw-material traceability, and customer-case information are unknown.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and Limited Company in China, with its head office and operations in Qingdao, Shandong. Its stated business focus is manufacturing sewage-treatment and environmental-protection equipment.

CertificationsThe supplier reports ISO 9001 certification. An SGS audit record is also provided with validity from October 20, 2025 to October 19, 2026, but the audit result is recorded only as “0,” so no positive audit conclusion can be established from that value.

After-Sales capabilityThe company states that it offers comprehensive technical solutions for after-sales service and invites customers to contact it with industry questions. However, its inventory, overseas warehouse, and overseas showroom service capabilities are marked unknown, so the broader service infrastructure cannot be verified.

R&D capabilityThe supplier describes continuous innovation, advanced manufacturing equipment, and reliable technology, while reporting 6–10 years of total R&D-engineer experience. Specific new-product development, ODM, SDK, or documented innovation results are marked unknown.

Production capacityThe supplier is identified as a manufacturer with 5 production lines, 6–10 quality-control staff, a listed pyrolytic chamber machine product, and a stated off-peak lead time within 15 workdays. These data support established production capability, although capacity details beyond the stated output and lines are limited.
