USITC Schedules Final Phase of Citric Acid Duty Investigations
On September 11, 2026, the US International Trade Commission announced the scheduling of the final phase of antidumping and countervailing duty investigations on citric acid and citrate salts from Canada and India. The inquiry focuses on whether imports from these countries injure the US industry.
What changed
The USITC scheduled the final phase of investigations regarding antidumping and countervailing duties on citric acid and certain citrate salts from Canada and India, covering various tariff subheadings under the Harmonized Tariff Schedule.
The notice later cites preliminary findings of subsidies in Canada and India and below-fair-value sales from India, but not Canada. Its opening summary mistakenly says “China” where the title and later paragraphs say “India”; readers should check the investigation numbers and the underlying Commerce notices.
The investigation assesses material injury to the US industry, with important deadlines including prehearing briefs by January 5, 2027, a hearing starting January 12, and posthearing briefs by January 20. The scope includes both unblended and blended products containing at least 40% citric acid or citrate salts.
Participation requires filing appearances and filings are electronic only via the Commission's system.
Steps to Comply with USITC Citric Acid Investigation Notice
- Check if your imports fall under the specified citric acid and citrate salts tariff codes.
- Submit a notice of appearance electronically by the deadlines if participating as a party.
- File required briefs and testimony by the stated deadlines: January 5 (prehearing), January 11 (hearing materials), January 20 (posthearing).
