Supplier typeThe supplier is explicitly identified as a professional technical supplier. Its stated business scope includes production and sales of non-licensed chemical products, building materials, high-performance sealing materials, and technical services; its primary product is sealant.

However, it has no overseas warehouse, showroom, agent, or branch, limiting the evidenced overseas service infrastructure.

Nevertheless, it has no valid contract with its associated subcontractor for manufacturing capacity, creating a stated production-governance deficiency.
