How to Verify That Water-Based PU Was Made at the Stated Facility

Confirming where a water-based polyurethane product was made takes more than a company profile or product listing. For PU-3822, verify the manufacturer and product identity, then request records that connect the specific batch to the Yingde production base and its quality inspection results.

Start with the Product and Manufacturer

The supplier identifies PU-3822 as a water-based polyurethane dispersion manufactured by Guangzhou Guanzhi New Material Technology Co., Ltd., under the GUANZHI brand. The stated production base is in Kaidi Chemical Park, Yingde, Qingyuan; the company’s headquarters is in Guangzhou Science City. Check that the manufacturer, product code, and production location appear consistently across supplier documents, batch records, and shipment paperwork.

PU-3822 is described as a cost-effective, solvent-free aliphatic polyurethane dispersion. Its stated properties include high solid content, thickening performance, flexibility, elongation, resilience, low-temperature flex resistance, water fastness, scratch resistance, storage stability, and an organotin-free formulation.

Build a Batch-Level Evidence Trail

Ask the supplier for records that identify the PU-3822 batch or production reference, name the Yingde site, show inspection results, and correspond to the shipment being considered. Factory quality checks are reported to include solid content, pH, viscosity, and particle size distribution. Compare the batch inspection data with the product specification and dispatch documents before approving supply.

A company’s production information can provide useful context. Guangzhou Guanzhi reports multiple automated water-based production lines, ABB robots, and laboratory equipment including high-low temperature test chambers, laser particle size analyzers, aging testers, and infrared spectrometers. These details are checkpoints for reviewing site information, but they do not replace documentation tied to the individual batch.

Use Certifications and Business Records as Supporting Evidence

Guangzhou Guanzhi reports holding a QUALITY MANAGEMENT SYSTEM CERTIFICATE, certificate number 28026Q0875R000. Its stated scope covers 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 lists a Certificate of Intellectual Property Compliance Management System Certification, number 404IPI251042ROM.

These certifications provide information about the company’s management systems and technical credentials; they do not, on their own, establish the origin of a particular shipment. Likewise, reported cooperation with PPG and Nippon Paint in China for coating applications indicates industry experience, but is not batch-level proof of PU-3822’s manufacturing site.

Verification Checklist

Applications and Product Fit

Compare the intended use with the supplier’s product information. PU-3822 is listed for nylon paste, denim paste, thick plate paste, leather finishing, fiber sizing, inks, and related industries. The company also describes applications in flexible materials, including textiles, printing leather, ink, and adhesives.

Frequently Asked Questions

What should I request to confirm the manufacturing facility?

Request documents that link Guangzhou Guanzhi, PU-3822, the Yingde production base, the relevant batch or production reference, inspection results, and shipment details. The available product information does not specify a particular batch certificate, so ask the company for the applicable records directly.

Does a product page confirm where a particular batch was made?

No. A product description can establish the product’s stated identity and features, and a company profile can name a production base. To verify a specific shipment, obtain records connecting its batch to that facility.

What product details can help check that the supply is PU-3822?

Compare the product code and description with the stated uses and properties. Listed uses include textile and leather applications, fiber sizing, and inks; stated properties include flexibility, water fastness, and scratch resistance.

Conclusion

For a reliable origin check, match the supplier identity and PU-3822 product code with the Yingde site, batch-specific inspection results, and dispatch records. The company describes an R&D, manufacturing, and direct-sales model, with a 900 KG minimum order quantity and a 7-10 day delivery time. Review its certifications as supporting company information, and obtain direct batch evidence before accepting the material. For technical assistance, contact sophia@guanzhihg.com.
