USITC Begins Second Review of Duties on Solar Products from China and Taiwan

Estimated reading time: 3–5 minutes

The United States International Trade Commission (USITC) has started a five-year review of rules about crystalline silicon photovoltaic products, also known as certain types of solar panels, from China and Taiwan. The review began on August 1, 2025.

The review will decide if removing current duties—a type of tax—on these products would hurt the solar panel industry in the United States. The review looks at both antidumping and countervailing duties against China, and antidumping duties against Taiwan.

Background

In 2015, the Department of Commerce placed special duties on solar products from China because of unfair pricing and government support. Taiwan was also named in the orders for selling products at less than fair value. The orders were continued after a review in 2020.

Now, as required by law, the USITC will again consider if those duties are still needed. If the Commission finds that removing the duties will hurt U.S. businesses, the duties can stay in place.

Key Details

  • The USITC calls the solar panels “Subject Merchandise.” The review covers China and Taiwan (“Subject Countries”).
  • US makers of similar solar products are considered the “Domestic Industry.” The main issue is if ending the duties hurts these U.S. producers.
  • People or groups—including importers, producers, unions, and business associations—who want to take part as parties in the review must file paperwork within 21 days after the notice.

How to Respond

Anyone sending information to the USITC must give:

  • The name, address, and contact details of their business or group.
  • A statement about who they are—such as a producer, importer, or association.
  • Whether they will give information during the process.
  • Details on how taking away the duties would affect them and the U.S. solar industry.
  • Lists of companies making or importing covered solar panels, leading buyers, and sources for price info.

Producers and importers also have to give data about their sales, production, and profit for 2024. This includes numbers of panels sold, value of sales, manufacturing costs, and operating income.

Deadlines

  • All responses must be given by September 2, 2025, at 5:15 p.m.
  • Comments about the adequacy of the responses can be submitted by October 10, 2025, at 5:15 p.m.

Submitting Information

The USITC only accepts electronic filings, using its Electronic Document Information System (EDIS) at https://edis.usitc.gov. No paper copies will be accepted for now.

If someone cannot give the requested information, they must explain why and offer other ways to provide similar information. Not responding fully may lead the USITC to use negative assumptions about the missing information.

Other Rules

  • Some confidential business data will be shared only with authorized people under a protective order.
  • Anyone submitting data must certify that it is true and complete.
  • Past USITC employees can participate in these five-year reviews even if they worked on earlier stages of the case.
