Nurturing a culture of trust
Supply chain management

Aiming to building a sustainable supply chain, we work together with our partner companies and other business partners to promote initiatives.

Basic approach

The Haseko Group’s business activities are possible due to the support of our many partner companies and other business partners. We consider our business partners to be valuable partners in promoting sustainability.
The Haseko Group promotes procurement activities in accordance with the Haseko Group Sustainable Procurement Guidelines (hereinafter, “the Guidelines”) with the purpose of building a sustainable supply chain. The Guidelines establish basic matters in conducting procurement activities that are conscious of the environment and society. We ask all of our business partners, including subcontractors and agents, to adhere to the Guidelines when conducting business activities.

※From April 2025, the 'Haseko Group CSR Procurement Guidelines ' has been renamed and is now being operated as the 'Haseko Group Sustainable Procurement Guidelines'.

Implementation of the Sustainable Procurement Guidelines

To ensure the effective implementation of the Guidelines, we obtain written consent on the Guidelines from the partner company organizations of our Group companies, which are our main business partners. In order to clarify the requirements of the Guidelines for other business partners as well, we are also adding compliance clauses of the Guidelines to contracts or obtaining written consent.
Furthermore, by conducting a questionnaire of our business partners since fiscal 2022, we are working to confirm adherence to the Guidelines and promote understanding and permeation of our initiatives.

Below is an overview of the business partner questionnaire conducted in fiscal 2024.
