簡介Introduction：

本評估工具按照《中國礦產供應鏈盡責管理指南》（第二版）提供的盡責管理詳細要求，旨在評估企業盡責管理體系和管理過程中的績效，發現改進之處以及制定相應的改進措施。評估分為主評估和跟蹤評估，主評估一年需開展一次；跟蹤評估則根據不符合類型，每三個月、六個月或在再評估（主評估）中開展績效跟蹤評估。

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).
