BLJ also maintains inventory capability and has seven years of export experience, with exports representing 21%–30% of total sales. However, the supplier reports no valid manufacturing-capacity contract with affiliated subcontractors, no overseas warehouse, showroom, agent, or branch, and services in zero countries. The provided information does not establish financial strength, specific customer cases, or sufficient production-scale capacity.

Supplier typeBLJ operates in technical services, technology development, import and export, new membrane materials, building materials, water-resource equipment, environmental-protection equipment, ecological materials, plastic products, molds, and household products. This indicates a manufacturer and technology-oriented supplier rather than a narrowly defined trading-only company.
