Policy of Conflict Minerals
Conflict minerals are the four minerals (Tin, Tantalum, Tungsten, Gold) mined in the Democratic Republic of the Congo, the conflict area, and its surrounding countries.
The funds created by conflict minerals flow into the armed forces in the country, causing not only human casualties but also human rights violations such as human rights violations by local residents and exploitation of labor in the process of extracting minerals.
As the "Dodd-Frank Wall Street Reform and Consumer Protection Act", which includes the conflict mineral regulation clause, passed through the US Congress in July 2010, The obligation to report to the US Securities and Exchange Commission(SEC) whether the use of conflict minerals has become effective.
Therefore, companies listed on the US stock market must report the use of the conflict minerals, and domestic companies that deliver products to US  listed companies  are also affected by the regulations.

▪ By applying international standards regulating conflict minerals, we will establish a dispute mineral business process to comply with the law.

▪ We will investigate whether 3TG (tin, tantalum, tungsten, gold) used in our products are used for conflict minerals for domestic and overseas supplier by using the EICC Template of EICC-GeSI.  
▪ Then we will ask the vendor that uses the conflict minerals to submit a written Dispute Mineral Usage Reporting Questionnaire and Confirmation of non-use of conflict mineral

LK ENGINEERING requires all partners to comply strictly with its dispute mining policy.
