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.
