ANSI Approves SEIA’s New Supply Chain Traceability Standard for Solar and Storage Industry

The American National Standards Institute (ANSI) has approved a new American National Standard developed by the Solar Energy Industries Association (SEIA) to strengthen transparency across the solar and energy storage supply chain and support compliance with U.S. Customs and Border Protection (CBP) traceability requirements.

The new standard, ANSI/SEIA 101, establishes a clear framework for manufacturers and importers to trace the origins of products from raw materials through to finished goods. Designed for both companies and products, the standard provides comprehensive guidance for mapping and tracking every stage of the solar and storage supply chain.

Solar developers and manufacturers can use the standard to verify the sourcing of project components, while installers, insurers, and other stakeholders can require their vendors to comply with SEIA’s traceability protocols. Manufacturers can apply the standard to certify specific products as well as their broader business operations.

Developed through an industry-wide collaborative process, ANSI/SEIA 101 draws on real-world examples of solar product shipments that were detained and later cleared by CBP. The standard incorporates insights from manufacturers, project developers, and third-party auditors, providing the industry with a practical, transparent tool to enhance accountability and reinforce confidence in the integrity of the solar and storage supply chain.

“The U.S. solar and storage industry is deeply committed to operating with the highest ethical standards,” said SEIA president and CEO Abigail Ross Hopper. “As we expand domestic manufacturing across the solar and storage supply chain, this standard will help ensure that every solar and storage product installed in America reflects that commitment. SEIA’s industry-leading standards-setting work is a critical part of how we set solar and storage on a path to sustained success for decades to come.”
