AI-Powered supplier vetting

SummaryXiamen Umd Industrial Co., Ltd. is a China-based manufacturer/factory producing movable houses. It reports broad customization capability, OEM service for well-known brands, export activity, and markets across multiple regions. Production information includes container-house output of 50,000 sets and a one-month lead time, but quality-control resources and documented management procedures appear weak or incomplete: fewer than five quality-control staff, no quality-testing equipment, and no written corrective-action, complaint-handling, or supplier-assessment procedures. No certifications, customer cases, or after-sales infrastructure are identified. Financial information is limited to references to records for 2021–2023 without substantive financial results.

Supplier typeThe supplier is identified as a limited company and manufacturer/factory in China, offering movable houses. It has 12 employees and is not part of a larger company group.

After-Sales capabilityThe supplier reports no overseas showroom, overseas agent or branch, or offline trade-show participation. It also has no written procedures or records for handling customer complaints or corrective and preventive actions, indicating limited documented after-sales support.
