U.S. Reviews Antidumping Orders on MSG from China and Indonesia

Estimated reading time: 3–5 minutes

The United States International Trade Commission (USITC) has started a new review. This is the second five-year review of antidumping duty orders on monosodium glutamate (MSG) from China and Indonesia. The main question is if removing the orders would harm U.S. companies again.

Key Dates for the Review

The review began on October 1, 2025. Anyone interested must send their responses by October 31, 2025. Comments about whether responses are good enough must be filed by December 11, 2025.

What Is Being Reviewed

MSG is the product under review. MSG is mainly produced in the U.S. by Ajinomoto North America, Inc. Imports from China and Indonesia are being checked. The USITC wants to know if ending duties would bring back problems for U.S. producers.

Who Can Take Part

Any person or group who uses, sells, or produces MSG can join. This includes industrial users, sellers, and consumer groups. To join, they must file an entry within 21 days after October 1, 2025.

What Is Needed From Participants

Participants must give specific details. This includes:

  • Their name, address, and contact details.
  • If they are an “interested party” under U.S. trade law.
  • If they will help in the review.
  • How removing the duties might affect them or the entire U.S. industry.
  • A list of all U.S. MSG makers and related parties.
  • A list of all U.S. importers and export firms since 2019.
  • Names and contacts of big U.S. buyers.
  • Places to find info on MSG prices.
  • Data about their operations with MSG during 2024, including production, capacity, sales, and profits.

Special Rules for Submissions

Every document must be filed electronically at EDIS. No paper filings are allowed now.

Any data sent must be certified as correct. If a party cannot give all information, they must explain why, or the Commission might assume the worst (“adverse inference”). Some sensitive business information can be given under a protective order.
