AI-Powered supplier vetting

SummaryQingdao Guanshan Industry Co., Ltd is identified as a China-based limited company in Shandong, with conflicting classifications as a trading company and manufacturer/factory. Its stated business covers plastic and rubber product processing, manufacturing, and wholesale. Evidence indicates production equipment, flexible customization, ODM services, and OEM services for well-known brands. Service procedures, corrective-action procedures, and complaint-handling records are reported, while peak- and off-season lead times are within 15 working days. However, the supplier reports no new products launched in the past year, one R&D engineer, no SDK, no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Certification holdings, customer cases, raw-material traceability, and fire-drill status are not sufficiently evidenced. Financial information is referenced for multiple years, but the provided slices do not establish financial strength.

After-Sales capabilityThe supplier reports written procedures and implementation records for service-capability assessment, corrective and preventive actions, and customer-complaint handling. It also states lead times within 15 working days in both peak and off-season, but the evidence does not specifically describe warranty, repair, replacement, or post-delivery support.

R&D capabilityThe supplier provides ODM services, but it reports only one R&D engineer, no available SDK, and no new products launched in the past year. The explicit absence of recent product launches and the limited stated R&D resources indicate a deficiency in demonstrated innovation performance.

Production capacityThe supplier states that it has two automatic auxiliary-machine rubber mixing centers, two precision rubber mixing centers, four large foam vulcanization production lines, and large coating machines. Its declared processing and manufacturing scope covers plastic and rubber products, and it is also identified as a manufacturer/factory, providing explicit evidence of production infrastructure.

Customization capabilityThe supplier explicitly offers flexible customization and ODM services, demonstrating both customized design/manufacturing availability and stated flexibility. OEM service for well-known brands further supports its ability to produce according to customer or brand requirements.

Product Q&A

Q:Can I get samples of different densities?

Yes, we provide A4 size samples free of charge; you just need to provide the courier account number. Samples of special colors will take longer to prepare and there will be a charge.

Q:Can I buy small quantities?

There is no problem at all. We will account for all costs incurred in production and transportation according to your size and quantity. We can reduce this extra cost if you buy multiple models of foamed products at the same time.

Q:Can you use carton box packaging?

Yes, we can customize your cartons, including logos and text printed on them. According to the density of EPDM foam board, we calculate the size of each carton to reduce individual carton size, and double corrugated design is a must.

Q:Can you offer cutting or die-cutting services?

Of course, we are very happy to provide this service. Please provide drawings, dimensional requirements, and performance specifications for pricing. We can also sign an NDA if required.

Q:What is the lead time for production?

The average lead time is within 15 workdays for both peak season and off-season.
