Employees of Duksung must not give or accept any form of monetary gift (cash, gift cards, fuel vouchers, etc.), entertainment, excessive hospitality, or gifts with a value exceeding KRW 50,000. Bribery or the provision of kickbacks or entertainment to secure or maintain business with clients is strictly prohibited. If such an item is delivered to an employee’s home, it must be refused, and the sender must be clearly informed.

Support or sponsorship from suppliers for personal events (e.g., weddings, funerals) or department gatherings is not permitted. Employees must also refrain from any form of gambling involving monetary stakes (e.g., golf bets, card games). Violations may result in serious disciplinary action, including termination.

Duksung employees must not solicit or exert any form of pressure on supplier employees, including private requests such as requests to enroll in insurance. Meals with suppliers should be taken at the company cafeteria whenever possible. If dining externally is unavoidable, the expense must be within socially acceptable norms.

Using authority or position to make unreasonable demands or seek compensation under the guise of work is strictly prohibited.

Any unethical behavior, whether explicitly listed here or similar in nature, must be reported promptly to the department head or responsible executive. Whistleblowers are fully protected, and their confidentiality is strictly maintained.
