It reports that exports account for 90% of sales and offers customization from samples and ODM services. Its stated product focus includes rock drills, drilling tools, drilling rigs, and related equipment. However, the available evidence shows no inventory, overseas warehouse, or overseas showroom capability; no Fortune 500 customer cooperation; no new products launched in the past year; and only one R&D engineer. Formal supplier approval, corrective/preventive action, complaint-handling, and service-capability assessment procedures are not documented.
