Yuchai Conflict Minerals Policy Statement


On August 22, 2012, the United States Securities and Exchange Commission (SEC) adopted a new rule under section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act mandating that all SEC registrants (including foreign issuers) are to report and disclose on their use of specified conflict minerals, namely tin, tungsten, gold and tantalum in the products which they manufacture or contract to manufacture emanating from the Democratic Republic of Congo and/or nine adjoining countries (collectively the DRC Region). The purpose of this rule known as the Conflict Minerals Ruleis to reduce the funding of armed groups that are committing human rights abuses in the mining and extraction of such conflict minerals in the DRC Region.


China Yuchai International Limited (CYI) is committed to ensuring compliance with the requirements of the Conflict Minerals Rule. Suppliers using Conflict Minerals are encouraged to move to certified conflict free smelters and refiners, by relying on industry initiatives such as the Conflict Free Smelter Program (CFSP).


CYIs policy is to make reasonable efforts to require our suppliers to determine if Conflict Minerals are used in their supplies to CYI, and if so, to disclose the sources of Conflict Minerals used. These efforts include the conduct of due diligence on its suppliers based on the guidance issued by the Organization of Economic Co-operation and Development (OECD) for Responsible Supply Chains of Minerals from Conflict-Affected and High Risk Areas (OECD Guidance) and continuing to refine its internal processes and systems.

A Project of Guangxi Yuchai Machinery Co., Ltd Won the 2nd Prize of 2015 Guangxi Award for Scientific and Technological Advancement

On November 30, it is reported by Guangxi Science and Technology Department that the project of the Development and Practice of Key Technology of Engine Manufacture Quality Project of Guangxi Yuchai Machinery Co., Ltd won the 2nd prize of 2015 Guangxi Award for Scientific and Technological Advancement.


Since 2008, the update of engine discharge technology has been requiring higher and higher towards the quality of engine and its fittings. To make high quality engine, Engineering Research Institute, Quality Department, Casting Division and the like institutes executed special breakthroughs, solved lots of critical technical issues, and attained certain technical creative achievements. For example, firstly, the issue of long period of new products research and development, which cannot rapidly respond to market demands, was solved. For this case, Guangxi Yuchai Machinery Co., Ltd. is the first enterprise in China to integrate and innovate APQP, DFMEA, CAE, PPAP and the like international advanced R & D quality control technologies and put them into practice, and build the advanced YCEDP analysis driver R & D process, reducing the period of new products R & D from 4-5 years to 2.5 years to reach the top level in China. Secondly, Guangxi Yuchai Machinery Co., Ltd. broke the capability limits of quantitative assessment of reliability level for manufacturing large numbers of engines. Upon analyzing historical quality information of more than 600,000 sets of engines in the nearly latest 10 years, and establishing assessment target towards the utility and lifetime of engine, Guangxi Yuchai Machinery Co., Ltd. innovated reliable assessment system of R0, Rf, R+and B10 engines, continuously assisted in promoting the reliability of Yuchai engine. Thirdly, Yuchai Machinery Co., Ltd. solved the problem of low casting precision and unsatisfactory wall thickness of the large scale and high speed of casting production line, developed three-dimensional positioning accurate casting technology, so that the minimum wall thickness of cylinder head of engine is 3mm, which reaches the international level and is 25% higher than the normal level in China.


The execution of the project helped Guangxi Yuchai Machinery Co., Ltd. receive the steady-state growth in incomes, and contributed to the authorization of 7 patents, includes 6 patents of invention, and formulation of 5 national standards. The project technology is popularized and applied in national well-known vehicles and matched fittings enterprises, such as, Henan Yutong, Liuzhou Motor, Guilin Fuda, Zhejiang Yinlun, Beijing Foton with good effects achieved, and helped other application institutes newly increase the sales revenue of about RMB 1,670,000,000 in grand total and tax of about RMB 192,000,000.
