How to Verify the Manufacturing Site of Water-Based PU

To establish whether water-based PU comes from its declared facility, trace the supplier, product, manufacturing site, and quality records for the same shipment. For PU-3822, confirm the manufacturer and Yingde production base, then request batch-specific documentation that ties the material to that location before approving an order.

Start with Shipment-Level Traceability

Company and product information provide useful context, but they do not by themselves prove where a particular batch was made. Ask Guangzhou Guanzhi New Material Technology Co., Ltd. for records that identify PU-3822, its batch or production reference, the Yingde site, test results, and dispatch details. Check that the identifiers and dates align across the documents.

Evidence to Request

• Supplier records confirming Guangzhou Guanzhi New Material Technology Co., Ltd. and the GUANZHI brand.
• Product documentation naming PU-3822 as a water-based polyurethane dispersion.
• Production or batch records identifying the manufacturing base in Kaidi Chemical Park, Yingde, Qingyuan.
• Inspection results for solid content, pH, viscosity, and particle size distribution, matched to the relevant batch.
• Shipment records that connect the inspected batch with the material being supplied.

Assess the Site and Product Information

Guangzhou Guanzhi lists its headquarters in Guangzhou Science City and its production base in Kaidi Chemical Park, Yingde, Qingyuan. The company reports multiple automated water-based production lines, ABB robots, and laboratory equipment that includes high- and low-temperature test chambers, laser particle size analyzers, aging testers, and infrared spectrometers. Use these statements as points to check against the facility information and records provided for the order.

PU-3822 is presented 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. Product descriptions can help confirm that the supplied grade matches the order, but they cannot establish the production origin of a specific batch.

Quality Systems and Supporting Credentials

The company states that factory inspection covers solid content, pH value, viscosity, and particle size distribution. Its product information also specifies a 12-month shelf life, technical support, and free reference formulas. For origin verification, request the actual inspection record for the batch under review rather than relying only on general product or company information.

Guangzhou Guanzhi holds a QUALITY MANAGEMENT SYSTEM CERTIFICATE, number 28026Q0875R000, covering research and production of environmentally friendly multi-purpose water-based polyurethane coating materials and high-performance environmentally friendly water-based coating additives. It also reports a Certificate of Intellectual Property Compliance Management System Certification, number 404IPI251042ROM. These credentials provide information about its management systems, but neither substitutes for records linking an individual batch to the Yingde facility.

Cooperation records name PPG and Nippon Paint as customers in China for coating applications. This indicates experience serving the coatings sector; it is not proof of the manufacturing location for a particular PU-3822 shipment.

Frequently Asked Questions

What records can link a batch to the Yingde facility?

Request production or batch records, inspection results, and shipping documents that consistently identify the supplier, PU-3822, the Yingde site, and the batch or production reference. The available product information does not specify a standard batch certificate, so ask the company which batch-level documents it can provide.

Does the company profile confirm the origin of a specific shipment?

No. A profile can state the location of a production base, but shipment-level confirmation requires documentation connecting the particular batch to that site.

Which uses are listed for PU-3822?

The described applications include nylon paste, denim paste, thick plate paste, leather finishing, fiber sizing, inks, and related industries. The company also lists uses involving textiles, printing leather, ink, and adhesives.

Practical Recommendation

Before approving supply, reconcile the manufacturer name, PU-3822 grade, Yingde facility, batch reference, inspection data, and dispatch records. Treat company certifications and customer references as supporting context, not as substitutes for batch-specific traceability. Guangzhou Guanzhi states a 900 KG minimum order quantity and a 7-10 day delivery time. For technical questions or support, contact sophia@guanzhihg.com.
