SEIA finalizes new national standard for solar supply chain traceability

By Kelsey Misbrener | October 10, 2025

The American National Standards Institute (ANSI) has officially approved a new American National Standard developed by the Solar Energy Industries Association (SEIA) to enhance transparency of the solar and storage supply chain and help companies comply with U.S. Customs and Border Protection’s (CBP) traceability requirements.

The newly approved standard, ANSI/SEIA 101, provides a rubric that manufacturers and importers can follow to trace product origins from raw materials to finished goods.

ANSI/SEIA 101 is based on real-world examples of solar product shipments that were detained and released by Customs officials and includes input from numerous stakeholders, including manufacturers, developers and third-party auditors.

“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.”

This supply chain standard applies to both companies and products, supporting solar developers and manufacturers throughout every facet of supply chain mapping and tracking.

Solar and storage developers can use the standard to track the origins of project components while installers, insurers, and other businesses relying on solar product information can require vendors to follow SEIA’s standard. Manufacturers can use the standard to certify an individual product, as well as their business.

As an ANSI-accredited standards developer, SEIA has been convening diverse stakeholders to develop a suite of standards that proactively and responsibly manage the industry’s growth. Earlier this year, ANSI approved three standards on consumer protection; operations and maintenance; and residential and small commercial installation. In addition to these four approved standards, SEIA is developing seven more industry-wide standards that cover a range of issues, including installation and project decommissioning.
