Published Date: 9/22/2026
Notice
Summary
The U.S. Department of Commerce found that certain fatty acids from Indonesia are likely being sold in the U.S. for less than their fair price. This means importers from Indonesia might face extra duties soon. The final decision is delayed, but provisional measures are extended to protect U.S. businesses while the investigation continues.
Analyzed Economic Effects

Preliminary dumping margins announced
The Department of Commerce preliminarily set estimated antidumping margins for certain fatty acids from Indonesia: P.T. Musim Mas (and PT Inti Benua Perkasatama) at 23.04% (adjusted 22.96%), PT Wilmar Nabati Indonesia at 12.32% (adjusted 12.31%), and an all-others rate of 19.55% (adjusted 19.49%). These are preliminary estimated weighted-average dumping margins reported on the preliminary determination published September 22, 2026.
Suspension of liquidation and cash deposits required
Commerce will instruct U.S. Customs and Border Protection to suspend liquidation of entries of the subject fatty acids and to require cash deposits equal to the estimated dumping margins as of the publication of this notice on September 22, 2026. The notice states: (1) cash deposit rates for the named respondents equal the company-specific margins; (2) if the exporter is not a named respondent but the producer is, the deposit equals the producer-specific margin; and (3) the deposit for all other producers/exporters equals the all-others rate.
Retroactive suspension for some exporters (critical circumstances)
Commerce preliminarily found that critical circumstances do not exist for P.T. Musim Mas (and PT Inti Benua Perkasatama) and PT Wilmar Nabati Indonesia, but that critical circumstances do exist for all other exporters and producers. For those exporters/producers with a preliminary critical-circumstances finding, suspension of liquidation will apply to unliquidated entries entered, or withdrawn from warehouse, for consumption on or after the date which is 90 days before the publication of this notice (i.e., 90 days before September 22, 2026).
Final determination postponed; provisional measures extended
At the request of Musim Mas and PT Wilmar, Commerce postponed the final determination and extended provisional measures from a four-month period to a period not to exceed six months. Commerce will make its final determination no later than 135 days after the publication of this preliminary determination (publication September 22, 2026). The exporters made their postponement/extension requests on September 3 and September 4, 2026.
