Commerce hits Indonesian solar cells with dumping duties

## Summary

The U.S. Department of Commerce found that solar cells from Indonesia are being sold in the U.S. for less than their fair price. Starting September 16, 2026, extra duties will apply to these imports to protect American businesses. This means companies importing these solar cells should expect changes in costs and rules soon.

## Abstract

The U.S. Department of Commerce (Commerce) determines that imports of crystalline silicon photovoltaic cells, whether or not assembled into modules (solar cells) from Indonesia are being, or are likely to be, sold in the United States at less than fair value (LTFV). The period of investigation (POI) is July 1, 2024, through June 30, 2025.

- 94.36% Antidumping Cash Deposit: cost, high.

- ITC Decision Could Trigger Duties: cost, high. Commerce will notify the U.S. International Trade Commission (ITC), which must decide within 45 days whether U.S. industry is materially injured. If the ITC finds injury, Commerce will issue an antidumping order and CBP will assess antidumping duties on imports entered, or withdrawn from warehouse,…
- Many Small Panels Excluded from Duties: benefit, medium. Several specific products are excluded from the investigation and thus are not subject to the antidumping measures. Examples include thin-film PV products (a-Si, CdTe, CIGS), crystalline silicon PV cells permanently integrated into a consumer good not exceeding 10,000 mm², small panels/panels with…
