SummaryZhengzhou Kelai Chemical Co., Ltd. is identified as a trading company headquartered in Zhengzhou, Henan, with permitted import and export activities. The provided information describes fine-chemical R&D, production, operations, and exports to more than 68 countries, although other records characterize the entity as a chemical-products trading business.

Service logistics include warehousing, contract-carrier transportation, and stated lead times within 15 working days in both peak and off-season periods. However, it has no overseas showroom, agents, branches, or offline trade-show participation, and no SDK is available. Financial records are indicated for 2023–2025, but no substantive financial-performance evidence is provided. Supplier-management procedures are not documented, and customer evidence is limited to general claims of OEM service for known brands and exports...

Supplier typeThe supplier is explicitly classified as a trading company, with permitted import/export activities and a Zhengzhou, Henan location. Its background description also states involvement in fine-chemical R&D, production, and operations, so the available records present both trading and product-related capabilities.

CertificationsThe supplier reports holding ISO 14001 and ISO 9001 certifications. These are explicit certifications relevant to environmental and quality management systems.

After-Sales capabilityService support includes warehousing, contract-carrier transportation, and stated lead times within 15 working days in both peak and off-season periods. However, the supplier reports no overseas showroom, agents, branches, or offline trade-show participation, and offers overseas services in zero countries; therefore, after-sales coverage is not demonstrated as strong, particularly internationally.

R&D capabilityThe supplier reports R&D capability, at least one new product during the past year, and ODM services; its company background describes fine-chemical R&D. However, it explicitly has no available SDK, so innovation support is evidenced for product development but not for SDK-based integration.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, minor customization, flexible customization, and customization from designs. It also reports ODM availability, providing direct evidence of broad customization support.
