SummaryThe supplier is identified as a limited trading company in Changzhou, with 13 employees and products including coil nails, staples, rebar tie wire, hog rings, and air tools. It reports strong customization, 3D design, ODM, OEM, and recent new-product capabilities. Export activity is substantial, with 71%–90% of sales from exports, 13 years of exporting, and self-operated import/export rights. Service records show procedures for corrective actions and customer complaints, while supplier-capability assessment has records but no written procedure. Inventory capability and participation in an offline trade show are confirmed, but no overseas warehouse, showroom, agent, branch, or overseas service country is reported. Quality assurance status, outsourcing procedures, valid manufacturing-capacity contracts, certifications, and financial performance details are not sufficiently established by the provided information.

Supplier typeThe supplier is explicitly described as a limited company and a trading company, located in Changzhou, with 13 employees and no larger-company group affiliation. Its stated product scope covers coil nails, staples, rebar tie wire, hog rings, and air tools.

After-Sales capabilityThe supplier has documented procedures and follow-up records for corrective and preventive actions and customer complaints.
