Invitation for Quotation and Comparison of Supervision Units for the 10,000-Ton Battery-Grade Soda Ash Project of Chongqing Xiangyu Salt & Chemical Co., Ltd.

                   ：  
Our company plans to build a new 10,000-ton-per-year battery-grade soda ash project and is now selecting a supervision unit through an inquiry and price comparison process. We would like to invite your company to participate in the bidding. Please provide a quotation for the technical service fees related to this project.
I. Project Overview:
1. Project Location: Chongqing Xiangyu Salt & Chemical Co., Ltd.
2. Project Overview: This project proposes the construction of a new 10,000-ton-per-year battery-grade soda ash plant. The plant’s process flow can be divided into six major units: mother liquor refining, MVR evaporation, centrifugal washing, drying, pulverization, and packaging. Specifically, the heavy-grade soda ash product is dissolved to form a mother liquor, which then undergoes several refining steps—including magnetic separation, sedimentation, and filtration—before being fed into an MVR system for evaporation and crystallization. After evaporation is complete, the resulting crystal slurry is subjected to multiple processing stages, including centrifugal washing, drying, and air-flow mill pulverization, before finally being packaged into finished products. The total investment for this project amounts to 39.0069 million yuan, of which 38.6319 million yuan is allocated to construction costs. From the official approval of the project to the start of trial production, the estimated construction period is nine months.
The control price for the procurement of project construction supervision and technical services is 828,000 yuan. The required duration for the supervision services is from October onward (excluding the two-month free service period).
II. Scope of Services and Requirements:
See the technical agreement for details.
