How to Verify That Water-Based PU Was Produced at the Declared Facility

Verifying the production origin of water-based PU requires more than reviewing a product brochure. The supplier name, product code, manufacturing site, batch records, inspection results, and shipping documents should all point to the same source. For PU-3822, the declared manufacturer is Guangzhou Guanzhi New Material Technology Co., Ltd., with production reported at its base in Kaidi Chemical Park, Yingde, Qingyuan.

Verification Priorities

• Confirm that Guangzhou Guanzhi New Material Technology Co., Ltd. is the legal supplier and that PU-3822 is the specified water-based polyurethane dispersion.
• Match the stated Yingde production base with official supplier documents, factory information, and shipment records.
• Request batch-specific evidence, including production references, certificates of analysis, inspection results, and dispatch documents.
• Compare the declared product uses with the material supplied, including textile coatings, leather finishing, fiber sizing, inks, adhesives, and other flexible-material applications.

How the Facility Verification Should Work

A reliable origin check connects four elements: the legal manufacturer, the product identity, the physical production location, and quality-control records for the relevant shipment. PU-3822 is presented as a cost-effective, solvent-free aliphatic polyurethane dispersion. Its described performance includes high solid content, thickening capability, flexibility, elongation, resilience, low-temperature flex resistance, water resistance, scratch resistance, storage stability, and an organotin-free formulation.

Guangzhou Guanzhi states that its manufacturing base is located in Kaidi Chemical Park, Yingde, Qingyuan, while its headquarters is in Guangzhou Science City. The reported facility includes several fully automated water-based production lines, ABB robots, and laboratory equipment such as high-low temperature test chambers, laser particle size analyzers, aging testers, and infrared spectrometers. These claims can be checked against factory documents, audit records, photographs, or an on-site inspection.

Link the Batch to the Site

The most important request is documentation that identifies the product name, batch number or production reference, manufacturing site, test results, and shipment details together. The stated factory inspection items include solid content, pH value, viscosity, and particle size distribution. Ask the supplier to provide the relevant records for the exact batch being purchased rather than relying only on general company information.

The product information also indicates a 12-month shelf life, technical assistance, and free reference formulas. These details may support supply evaluation, but they do not by themselves confirm the manufacturing origin of an individual shipment. The declared minimum order quantity is 900 KG, with an estimated delivery period of 7-10 days, so the purchase order and dispatch documents should also be checked for consistency.

Corporate and Quality Credentials

Guangzhou Guanzhi holds a QUALITY MANAGEMENT SYSTEM CERTIFICATE, certificate number 28026Q0875R000. The certification covers the research and production of environmentally friendly multi-purpose water-based polyurethane coating materials and high-performance environmentally friendly water-based coating additives.

The company also holds a Certificate of Intellectual Property Compliance Management System Certification, certificate number 404IPI251042ROM. These certifications provide supporting evidence of the company’s management and technical systems. However, they should be treated as corporate credentials rather than direct proof that a specific PU-3822 batch was made at the Yingde facility.

Reported cooperation with PPG and Nippon Paint in China demonstrates experience in coating-related business. Such customer references can strengthen supplier due diligence, but they cannot replace batch-level records or independent confirmation of the production site.

Evidence Checklist

Frequently Asked Questions

Which documents should be requested from the supplier?

Ask for documents connecting Guangzhou Guanzhi, PU-3822, the Yingde production base, the relevant batch or production reference, quality inspection data, and shipping information. Because a specific batch certificate is not included in the available product information, it should be obtained directly from the supplier.

Is a product brochure enough to confirm the manufacturing site?

No. A brochure can describe PU-3822’s formulation, performance, and applications, while a company profile can identify the Yingde production base. Confirmation requires a document trail showing that the particular batch under review was produced and released from that location.

Which end uses are associated with PU-3822?

The material is described for nylon paste, denim paste, thick plate paste, leather finishing, fiber sizing, inks, textiles, printing leather, adhesives, and related flexible-material applications. These stated uses should be compared with the buyer’s technical requirements and the product documents supplied for the batch.

Conclusion and Recommended Action

Before approving PU-3822, reconcile the supplier identity, product code, Yingde production base, batch documentation, quality results, and dispatch records. The company describes an integrated R&D, manufacturing, sales, and technical-service model, with an annual production capacity of 30,000 tons and a stated 900 KG minimum order quantity. Review the management certifications as supporting evidence, but rely on batch-specific documentation to establish the actual manufacturing origin.
