Procurement Planning, Procurement Department


KIOXIA Group brings convenience to the lives of people around the world and contributes to the development of industry and society by supplying the market with semiconductor memory and SSD products that are essential for smartphones, servers, and many other electronic devices.

Our Procurement Department conducts business activities in countries around the world in order to expand our business, pursue the most advanced technology, and manufacture high-performance and high-quality products.

To respond more appropriately to various CSR risks in our expanded supply chain, we joined the Responsible Business Alliance (RBA) in 2021 in response to requests from our stakeholders, and are accordingly committed to responsible business practices.

In addition, we highly value the RBA Code of Conduct as a guideline for procurement activities. Therefore, we refer to and carefully examine it with regard to our CSR procurement policy. We have referenced it in the “KIOXIA Group Supply Chain Code of Conduct,” and have established this as the code of conduct for our procurement activities.

We ask that our suppliers promote business activities in line with the stipulations contained in the “KIOXIA Group Supply Chain Code of Conduct” both in the course of their own business activities and across their own supply chains.

KIOXIA Group Supply Chain Code of Conduct
(RBA Code of Conduct Version 8.0)

Version 8.0 (2024)

The Responsible Business Alliance (RBA) Code of Conduct establishes standards to ensure that working conditions in supply chains are safe, and that business is conducted responsibly, ethically, and with respect for human rights and the environment.

The Code may be voluntarily adopted by any business and subsequently applied by that business to its direct and indirect supply chain and subcontractors, including providers of contract labor.

To adopt the Code and become a participant (“Participant”), a business shall declare its support for the Code and conduct due diligence in line with the Code and its standards through the establishment of an effective management system.

Participants must regard the Code as a total supply chain initiative. At a minimum, Participants shall also require their next tier suppliers to acknowledge and implement the Code.

Fundamental to adopting the Code is the understanding that a business, in all of its activities, must operate in full compliance with applicable laws, rules, and regulations. In alignment with internationally recognized standards as listed under the References of this document, and drawing upon best practices in global supply chains, elements of this Code may go beyond legal compliance in order to advance social and environmental responsibility and business ethics. In no case can complying with the Code violate applicable laws. If, however, there are differing standards between the RBA Code and applicable laws, the RBA defines conformance as meeting the strictest requirements.

The provisions of this Code are derived from and respect internationally recognized standards including:

  • OECD Guidelines for Multinational Enterprises
  • UN Guiding Principles on Business and Human Rights
  • ILO Declaration on Fundamental Principles and Rights at Work
  • ILO Fundamental Conventions
  • UN Universal Declaration of Human Rights

The Code is made up of five sections:

  • Sections A, B, and C: Standards for Labor, Health and Safety, and the Environment, respectively.
  • Section D: Standards relating to business ethics.
  • Section E: Elements of an acceptable system to manage conformity to this Code.

The RBA is committed to obtaining regular input from stakeholders in the continued development and implementation of the Code of Conduct.


Participants commit to respect the human rights of workers, and to treat them with dignity. This applies to direct and indirect suppliers, as well as all workers including temporary, migrant, student, contract, direct employees, and any other type of worker.

The labor standards are as follows:

1) Prohibition of Forced Labor

Forced labor in any form, including but not limited to, bonded (including debt bondage) or indentured labor, involuntary or exploitative prison labor, slavery or trafficking of persons is not permitted. This includes transporting, harboring, recruiting, transferring, or receiving persons by means of threat, force, coercion, abduction or fraud for labor or services. There shall be no unreasonable restrictions on workers’ freedom of movement in the facility in addition to unreasonable restrictions on entering or exiting company- provided facilities including, if applicable, workers’ dormitories or living quarters. As part of the hiring process, all workers must be provided with a written employment agreement in their native language, or in a language the worker can understand, that contains a description of terms and conditions of employment. Foreign migrant workers must receive the employment agreement prior to the worker departing from his or her country of origin and there shall be no substitution or change(s) allowed in the employment agreement upon arrival in the receiving country unless these changes are made to meet local law and provide equal or better terms. All work shall be voluntary, and workers shall be free to leave work at any time or terminate their employment without penalty if reasonable notice is given, which shall be clearly stated in workers’ contracts. Participants shall maintain documentation on all leaving workers. Employers, agents, and sub-agents’ may not hold or otherwise destroy, conceal, or confiscate identity or immigration documents, such as government-issued identification, passports, or work permits. Notwithstanding the foregoing, employers can only hold documentation if necessary to comply with the local law. In this case, at no time shall workers be denied access to their documents. Workers shall not be required to pay employers’ agents or sub-agents’ recruitment fees or other related fees for their employment. If any such fees are found to have been paid by workers, such fees shall be repaid to the worker.

2) Young Workers

Child labor shall not be used in any stage of manufacturing. The term “child” refers to any person under the age of 15, or under the age for completing compulsory education, or under the minimum age for employment in the country, whichever is greatest. Workers under the age of 18 (Young Workers) shall not perform work that is likely to jeopardize their health or safety, including night shifts and overtime. Participants shall ensure proper management of student workers through proper maintenance of student records, rigorous due diligence of educational partners, and protection of students’ rights in accordance with applicable laws and regulations. Participants shall implement an appropriate mechanism to verify the age of workers. The use of legitimate workplace learning programs, which comply with all laws and regulations, is supported. Participants shall provide appropriate support and training to all student workers. In the absence of local law, the wage rate for student workers, interns, and apprentices shall be at least the same wage rate as other entry-level workers performing equal or similar tasks. If child labor is identified, assistance/remediation shall be provided.

3) Working Hours

Working hours shall not exceed the maximum set by local law. Further, a workweek shall not be more than 60 hours per week, including overtime, except in emergency or unusual situations. All overtime shall be voluntary. Workers shall be allowed at least one day off every seven days.

4) Wages and Benefits

Compensation paid to workers shall comply with all applicable wage laws, including those relating to minimum wages, overtime hours and legally mandated benefits. All workers shall receive equal pay for equal work and qualification. Workers shall be compensated for overtime at pay rates greater than regular hourly rates. Deductions from wages as a disciplinary measure shall not be permitted. For each pay period, workers shall be provided with a timely and understandable wage statement that includes sufficient information to verify accurate compensation for work performed. All use of temporary, dispatch and outsourced labor shall be within the limits of the local law.

5) Non-Discrimination/Non-Harassment/Humane Treatment

Participants shall commit to a workplace free of harassment and unlawful discrimination. There shall be no harsh or inhumane treatment including violence, gender-based violence, sexual harassment, sexual abuse, corporal punishment, mental or physical coercion, bullying, public shaming, or verbal abuse of workers; nor is there to be the threat of any such treatment. Companies shall not engage in discrimination or harassment based on race, color, age, gender, sexual orientation, gender identity or expression, ethnicity or national origin, disability, pregnancy, religion, political affiliation, union membership, covered veteran status, protected genetic information or marital status in hiring and employment practices such as wages, promotions, rewards, and access to training. Disciplinary policies and procedures in support of these requirements shall be clearly defined and communicated to workers. Workers shall be provided with reasonable accommodation for religious practices and disability. In addition, workers or potential workers should not be subjected to medical tests, including pregnancy or virginity tests, or physical exams that could be used in a discriminatory way. This was drafted in consideration of ILO Discrimination (Employment and Occupation) Convention (No.111).

6) Freedom of Association and Collective Bargaining

Open communication and direct engagement between workers and management are the most effective ways to resolve workplace and compensation issues. Workers and/or their representatives shall be able to openly communicate and share ideas and concerns with management regarding working conditions and management practices without fear of discrimination, reprisal, intimidation, or harassment. In alignment with these principles, participants shall respect the right of all workers to form and join trade unions of their own choosing, to bargain collectively, and to engage in peaceful assembly as well as respect the right of workers to refrain from such activities. Where the right of freedom of association and collective bargaining is restricted by applicable laws and regulations, workers shall be allowed to elect and join alternate lawful forms of worker representations.


Participants recognize that in addition to minimizing the incidence of work-related injuries and illnesses, a safe and healthy working environment enhances the quality of products and services, consistency of production and worker retention and morale. Participants also recognize that ongoing worker input and education are essential to identifying and solving health and safety issues in the workplace.

The health and safety standards are as follows:
