This phase involves in-depth technical deliberations covering production capacity, quality benchmarks, site constraints, heating methodologies, and client-specific customization needs. A preliminary solution proposal is formulated, with strict adherence to local regulatory frameworks for environmental protection, occupational safety, and energy efficiency.

Leveraging local power grid specifications, energy supply conditions, and environmental compliance requirements, the team designs equipment structures, process parameters, and supporting auxiliary systems. Deliverables include engineering drawings compliant with international standards (e.g., ISO, ASME) and detailed cost quotations. Following iterative technical negotiations to refine specifications, a formal confirmation agreement aligned with international commercial terms (e.g., Incoterms) is executed, explicitly defining technical benchmarks, acceptance criteria, and rights/obligations for cross-border collaboration.
