What is the product warranty?

We warranty our materials and workmanship. It is the culture of our company to address and resolve all customer issues to everyone's satisfaction, whether in warranty or not.

Do you guarantee safe and secure delivery of products?

Yes, we always use high quality export packaging. We also use specialized hazard packing for dangerous goods and validated cold storage shippers for temperature sensitive items. Specialist packaging and non-standard packing requirements may incur an additional charge.

How about the shipping fees?

The shipping cost depends on the way you choose to get the goods. Express is normally the most quickest but also most expensive way. By sea freight is the best solution for big amounts. Exactly freight rates we can only give you if we know the details of amount, weight and way.

AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing factory in Suichang County, Lishui, and a professional technical supplier. It supports sample-based, design-based, full, minor, and flexible customization, and provides ODM services, but does not offer 3D software design or OEM services for popular brands. ISO 9001 certification, documented inspection procedures, quality assurance, and raw-material traceability are reported. The supplier has in-stock capability and self-operated import/export rights, but lacks valid manufacturing-capacity contracts with related subcontractors, overseas warehouses, overseas showrooms, overseas agents or branches, and offline trade-show participation. Financial records are indicated for 2022–2024, although no financial figures are provided. No new products were developed in the past year, and corrective-action and complaint-handling procedures lack written procedures or records.

Supplier typeThe supplier is explicitly described as a professional technical supplier and a factory, with associated companies in manufacturing. This supports classification as a manufacturing-oriented professional technical supplier.

CertificationsThe supplier reports ISO 9001 certification for its management system. This is explicit evidence of holding a recognized quality-management certification.

After-Sales capabilityThe supplier reports quality assurance and raw-material traceability, but has no written procedures or records for corrective and preventive actions or effective customer-complaint handling. The evidence indicates quality-control support but a documented after-sales deficiency.

R&D capabilityThe supplier collaborates with universities and technical research institutes and invests in equipment to commercialize research outcomes, while also providing ODM services. However, it reported no new products in the past year and no available SDK, so innovation capability is supported but not consistently demonstrated across all indicators.

Production capacityThe supplier is a factory with in-stock capability, documented and consistently followed finished-product inspection instructions, self-operated import/export rights, and stated lead times of within 15 workdays to one month. Nevertheless, it has no valid manufacturing-capacity contract with related subcontractors, limiting evidence of secured capacity arrangements.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, flexible customization, and ODM services. It does not provide 3D software design, but the listed physical/product customization options demonstrate broad customization capability.
