Supplier typeThe supplier is explicitly classified as a trading company, with its business scope covering sales of mechanical equipment, hardware, electronic products, instruments, leather products, metal products, and related equipment manufacturing. Its associated-company industry is listed as wholesale and retail, reinforcing its trading-oriented profile.
CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification. These are explicit certifications relevant to quality management and product conformity.
After-Sales capabilityThe supplier reports maintenance and repair services through overseas agents or branches in Peru, Brazil, Argentina, and other countries. However, its service assessment, corrective-action, and complaint-handling procedures have no written records, and it has no overseas warehouse or showroom, so the evidence supports service availability but not fully documented service controls.
Production capacityStated annual capacities include 500 drilling rigs, 8,000 reverse-circulation drilling tools, 10,000 DTH hammers, 500,000 drill bits, and 100,000 drill pipes, with inventory capability also reported. However, the supplier is classified as a trading company and its valid manufacturing-contract status is unknown, so the scale of directly controlled production is not fully established.
Customization capabilityThe supplier explicitly offers customization from samples and designs, as well as ODM services. This indicates capability to support customer-specific product requirements, although no examples or scope limitations are provided.
