Supplier Communication and Collaboration

LONGi has established a relationship of mutual trust and assistance with our suppliers, building multiple channels for diverse communication. In 2023, we introduced the SRM Supplier Collaboration and Coordination Survey, which encompasses management rules, process transparency, collaboration efficiency, business ethics, and other topics. The objective is to collect supplier feedback and suggestions, enhancing cooperation efficiency with our partners. The survey collected 3,622 responses from 2,992 suppliers, indicating that suppliers have a high understanding of management rules, satisfaction with process transparency, and satisfaction with payment timeliness, overall satisfaction rate being more than 95%.

?LONGi maintained close collaboration with suppliers and propelled the “Four New” cooperative innovation program, and makes joint efforts to successfully promote the landing of a series of innovation achievements, inject new vitality into product upgrading and industry development. With the goal of reducing total costs or improving efficiency, we analyzed the functions and models of our products and services, consistently driving innovation within the supply chain and enhancing the value of customer products or services.

Supplier Empowerment

Embracing the concept of empowerment, LONGi provides systematic training and professional technical support, promotes the concept of sustainability, improves suppliers’ ESG management to a high standard, and collaborates with suppliers to achieve the sustainability of the supply chain. In 2023, LONGi conducted 258 supplier training sessions and carried out offline site visits to 28 key suppliers of 8 major material categories from silicon materials suppliers to module suppliers. We provided specialized guidance on key issues covering environment management, occupational health, production safety, and social responsibility management, enabling suppliers to develop systematic approaches to social responsibility.

During the reporting period, LONGi conducted 28 on-site supplier audits, did not finding any violation of child labor or forced labor; other findings were closed under LONGi’s coach and monitoring. Through on-site audits and remediation empowerment, we have driven suppliers to achieve:

In 2023, we launched the Supplier ESG Capacity Building Plan (2024-2028). Significant suppliers involving in this plan accounted for 55%2 of the total procurement expenditure of significant suppliers, and we plan to gradually increase this proportion to 80% during 2025-2028. We have established four key dimensions: compliance with socialresponsibility qualifications, management systems, labor rights, and EHS management capabilities, aiming to enhance our suppliers’ ESG capability. Through the implementation of this plan, we aspire to encourage suppliers to proactively practice ESG management and establish a sustainable procurement system.
