US Commerce Department sets final antidumping margins on xanthan gum from China, sustaining the 154.07% China-wide rate
US xanthan-gum importers must post Commerce-assigned cash deposits on China-origin entries from 16 July 2026 or face antidumping assessment at liquidation
Change
On 16 July 2026, the U.S. Department of Commerce published final results of its antidumping administrative review of xanthan gum from China (period July 2023–June 2024), setting exporter-specific weighted-average dumping margins, sustaining the 154.07% China-wide rate for firms without a separate rate, and directing Customs and Border Protection to assess duties and collect cash deposits on entries made on or after the publication date.
Why it matters
The final margins and the sustained 154.07% China-wide rate fix binding cash-deposit and assessment parameters that govern entry handling and liquidation. Cash deposits apply to entries entered or withdrawn from warehouse for consumption on or after the publication date and remain in effect until further notice; separate-rate non-examined firms take the weighted average of the Fufeng and Deosen margins, while firms without a separate rate and unreported entries take the 154.07% China-wide rate. Importers that fail to file the reimbursement certificate before liquidation face a Commerce presumption of reimbursement and assessment of double antidumping duties.
Implications
- — Importers of xanthan gum from China into the United States must post the Commerce-assigned cash-deposit rate on entries entered or withdrawn from warehouse for consumption on or after 16 July 2026 — the rate runs until further notice, and unreported or non-separate-rate entries default to the 154.07% China-wide rate.
- — Importers' trade-compliance teams must file the reimbursement certificate under 19 CFR 351.402(f)(2) before liquidation of relevant POR entries — failure lets Commerce presume the antidumping duties were reimbursed and assess double antidumping duties.
- — Customs brokers handling these entries must apply Commerce's assessment instructions at liquidation — importer-specific ad valorem rates where entered values were reported, per-unit rates where they were not, the Fufeng-and-Deosen weighted average for separate-rate non-examined firms (Jianlong, Jilin Meihua, Meihua, Ningxia), and 154.07% for China-wide-entity exporters and unreported entries — misapplied rates risk re-assessment.
Who is affected
- — Importers of xanthan gum from China into the United States
- — Importers' trade-compliance teams
- — Customs brokers handling subject xanthan-gum entries
What to watch
- — Disclosure: 21 July 2026 — Commerce to disclose its final-results calculations and analysis to interested parties within five days of publication.
- — Assessment instructions: on or after 20 August 2026 — Commerce intends to issue liquidation instructions to CBP no earlier than 35 days after publication.
- — Injunction window: by 14 October 2026 — if a timely summons is filed at the Court of International Trade, CBP is directed not to liquidate relevant entries until the 90-day statutory-injunction period from publication expires.
