The U.S. International Trade Commission has scheduled expedited five-year reviews under Investigation Nos. 731-TA-776-779 to determine whether revoking antidumping duty orders on certain preserved mushrooms from Chile, China, India, and Indonesia would likely lead to continuation or recurrence of material injury. On May 8, 2026, the Commission found the respondent interested party group response inadequate, triggering the expedited review process under 19 U.S.C. 1675(c)(3).
For compliance engineering teams managing antidumping duty calculations, this expedited review timeline creates a narrow window for monitoring potential rate changes. The staff report will be available to parties on the Administrative Protective Order (APO) service list on June 16, 2026, with a public version to follow pursuant to 19 CFR 207.62(d)(4). Written comments from interested parties must be submitted by 5:15 p.m. on June 23, 2026—a seven-day window from staff report release to comment deadline.
The Commission's determination that the respondent interested party group response was inadequate—made on May 8, 2026—is the key procedural trigger here. Under the expedited review framework established by 19 CFR parts 201 and 207, inadequate foreign respondent participation typically results in the Commission relying on existing record evidence, which historically favors order continuation. Commissioner David S. Johanson voted to conduct full reviews, but the majority decision stands.
Key Dates for Compliance Teams:
• May 8, 2026: Commission adequacy determination
• June 16, 2026: Staff report available to APO service list
• June 23, 2026, 5:15 p.m.: Written comments deadline
Systems pulling HTS classifications tied to preserved mushrooms must account for the possibility that these antidumping orders—originally established under Investigation Nos. 731-TA-776 through 779—could either continue unchanged or be revoked following this review cycle. Any revocation would eliminate the antidumping duty rates currently applied to these country-product combinations, directly affecting landed cost calculations and duty liability projections.
Trade compliance platforms caching duty rates for preserved mushrooms under the relevant HTS subheadings should flag these investigation numbers for monitoring. If Commerce extends its final results timeline, the comment deadline shifts to three business days after Commerce issues results—a variable that could invalidate hardcoded date logic in compliance workflows.
Data Integrity Note: Comments submitted after June 23, 2026 may not contain new factual information. Systems generating compliance documentation should ensure data freshness before this cutoff to avoid relying on stale rates in formal submissions.
The notice of institution was published at 91 FR 4622 on February 2, 2026. The domestic interested party group—including Giorgi, according to the Federal Register notice—submitted an adequate response, ensuring the review proceeds. For API consumers serving duty rate data, the practical question is whether the existing antidumping order rates remain valid or require revision following the Commission's final determination.
