简介Introduction：

本评估工具按照《中国矿产供应链尽责管理指南》（第二版）提供的尽责管理详细要求，旨在评估企业尽责管理体系和管理过程中的绩效，发现改进之处以及制定相应的改进措施。评估分为主评估和跟踪评估，主评估一年需开展一次；跟踪评估则根据不符合类型，每三个月、六个月或在再评估（主评估）中开展绩效跟踪评估。

This assessment tool is based on the detail requirements of due diligence provided by the Chinese Due Diligence Guidelines for Responsible Mineral Supply Chain (Second Edition), and aims to evaluate the performance of the company's due diligence management system and process, identify fields that need further improvements and formulate corresponding improvement measures. The assessment is divided into main assessment and tracking assessment. The main assessment needs to be carried out once a year; the tracking assessment is based on the type of non-conformity, and the performance tracking assessment is carried out every three months, six months or during the re-assessment (main assessment).
