AI-Powered supplier vetting

SummaryThe supplier is presented as a China-based filtration business operating under Zhejiang Grace Envirotech Co., Ltd. and the ECOGRACE brand, with manufacturing and trading-related descriptions appearing across the records. It offers filter bags, filter cloth, dust collectors, and related filtration products, and reports export experience of 10 years with 51%–70% of sales from exports. The supplier lists numerous management-system certifications, two production lines, 11–20 years of combined R&D experience, and customization from samples, designs, or full specifications. Quality-related evidence is mixed: finished products are checked by packing staff and randomly inspected, while one record reports only one quality inspector and no raw-material traceability identification. The provided information does not establish after-sales performance, financial credibility, or named customer cases.

Supplier typeThe supplier is identified as Hangzhou Createch Machinery Co., Ltd. in one record and Zhejiang Grace Envirotech Co., Ltd. in others. It is described both as a manufacturer/factory and a trade company, with operations in Hangzhou, Zhejiang, China and a foreign joint-venture ownership structure; therefore, the records support a manufacturing role but contain inconsistent entity descriptions.

CertificationsThe supplier lists ISO 9000, ISO 9001, ISO 14001, ISO 14000, ISO 20000, ISO 14064, TS 16949, OHSAS/OHSMS 18001, GMP, and QC 080000 certifications. The record does not provide certificate numbers, validity dates, or scope, but it explicitly reports multiple certifications.

R&D capabilityThe supplier reports 11–20 years of combined R&D engineer experience and presents itself as providing high-efficiency filtration solutions for industrial applications. Its product range includes specialized materials and products such as Nomex, PTFE, fiberglass filter bags, candle filters, and mist eliminators, supporting relevant technical capability, although no specific patents, new-product records, or R&D projects are provided.

Production capacityThe supplier reports two production lines, a filter-bag production and sewing facility, and an air-permeability tester. It also states that it maintains suitable stock and can expedite custom orders, while 51%–70% of sales are exports and exporting experience is reported as 10 years; however, the records do not establish actual capacity, output units, or lead-time metrics.

Customization capabilityThe supplier explicitly reports customization from samples, designs, full specifications, minor modifications, and flexible customization. Its description also refers to custom orders, providing direct evidence of broad customization capability for filtration products.
