Indonesia fatty acids antidumping duties now create immediate financial and operational consequences for U.S. oleochemical supply chains. The preliminary affirmative determination introduces exporter-specific cash deposits, suspended liquidation, and partial retroactive treatment, requiring importers and customs brokers to validate scope, supplier identity, entry dates, and AD/CVD case mappings.
What the Preliminary Determination Changes
The preliminary determination applies to certain fatty acids from Indonesia entered into the United States. It establishes estimated dumping margins for two examined respondents and an all-others rate for exporters and producers that do not qualify for one of the company-specific rates.
These measures are preliminary rather than final. Nevertheless, they affect current entry processing because U.S. Customs and Border Protection generally suspends liquidation and collects cash deposits while the investigation continues. The deposit secures estimated antidumping liability; it does not necessarily represent the final duty owed after the investigation and any subsequent administrative review.
Dumping Margins and Cash Deposit Rates
The applicable preliminary rates are:
| Exporter or Producer | Preliminary Dumping Margin | AD Cash Deposit Rate |
|---|---|---|
| P.T. Musim Mas and PT Inti Benua Perkasatama, treated as the Musim Mas single entity | 23.04% | 22.96% |
| PT Wilmar Nabati Indonesia | 12.32% | 12.31% |
| All other Indonesian exporters and producers | 19.55% | 19.49% |
The cash deposit rates are slightly lower than the corresponding dumping margins because they have been adjusted for export-subsidy offsets associated with the companion countervailing duty investigation. Those adjustments generally remain relevant while CVD provisional measures are in effect.
Importers and brokers should not substitute the dumping margin for the cash deposit rate in their case tables. Entry systems should store both fields separately, identify which rate is operationally applicable, and preserve the effective-date logic supporting the declaration.
The final determination has been postponed for up to 135 days after preliminary publication at the exporters’ request. Provisional measures have also been extended for up to six months. Rates, scope treatment, and company eligibility can therefore change before the proceeding reaches its final stage.
Critical Circumstances and Entry-Date Exposure
Critical circumstances determine whether suspension of liquidation and cash deposit requirements can reach entries made before publication of a preliminary determination. This issue is especially important because the outcome differs between the examined respondents and the all-others cohort.
Commerce preliminarily determined that critical circumstances do not exist for Musim Mas or PT Wilmar Nabati Indonesia. For qualifying merchandise tied to those entities, suspension of liquidation and cash deposit requirements generally begin with entries made on or after September 22, 2026, the publication date of the preliminary determination.
Retroactive Treatment for All Other Exporters and Producers
Critical circumstances were preliminarily found for all other Indonesian exporters and producers. As a result, covered merchandise in the all-others cohort may be subject to suspended liquidation and cash deposits for entries made up to 90 days before publication of the preliminary determination.
That distinction makes exporter and producer identification a substantive compliance issue rather than a routine master-data field. An importer cannot assume that a shipment of merchandise manufactured by an examined producer automatically receives that producer’s rate. The commercial chain, producer identity, exporter identity, invoicing structure, and applicable customs instructions must support the claimed case treatment.
Importers should review entries within the potential retroactive period, including shipments that were entered before the preliminary publication date. Relevant records typically include entry summaries, commercial invoices, purchase orders, manufacturer affidavits, bills of lading, product specifications, and broker transmission data. Teams should also identify entries that remain unliquidated and estimate the cash impact of possible retroactive deposits.
Critical circumstances are preliminary and may change in the final determination. Until official instructions are revised, however, brokers and importers generally must follow the active suspension and deposit requirements implemented by CBP.
Scope, Classification, and AD/CVD Controls
The product scope covers certain fatty acids with carbon chain lengths of C6, C8, C10, C12, C14, C16, or C18, an iodine value below 105 grams per 100 grams, and a degree of split of at least 97%. Product names alone are not sufficient to determine coverage because commercial descriptions can vary across suppliers, grades, blends, and end uses.
Importers should maintain specifications or laboratory data that address all relevant scope characteristics. Supplier documents should identify chain length, iodine value, and degree of split in a form that can be reconciled with purchase orders, invoices, technical data sheets, and entry records.
HTS Numbers Are Screening Tools, Not the Final Scope Test
The merchandise may be entered under several tariff classifications, including:
- 2915.70.0110
- 2915.70.0120
- 2915.70.0150
- 2915.90.1010
- 2915.90.1050
- 2916.15.1000
- 2916.15.5100
- 3823.11.0000
- 3823.12.0000
- 3823.19.2000
- 3823.19.4000
- 3824.99.4190
These classifications can support automated screening, but the written product description is dispositive. Merchandise can potentially fall within the investigation even when entered under a different tariff provision, while a listed HTS number does not automatically establish that every product classified there is covered.
Building Reliable Case and Supplier Controls
A strong control framework should connect product specifications, country of origin, manufacturer, exporter, entry date, HTS classification, AD case number, CVD case number, and applicable deposit rate. The AD and CVD proceedings remain separate, so both may require deposits when their respective conditions are met.
The Indonesia rates also must not be assigned to Malaysian merchandise. Malaysia is involved in a companion investigation, but its company rates, effective dates, and instructions require separate case mapping.
Importers should additionally recognize that antidumping cash deposits are generally outside customs drawback. Deposit amounts should therefore be incorporated into landed-cost forecasts, bond sufficiency reviews, purchasing decisions, and working-capital planning rather than treated as routinely recoverable through drawback claims.
- Commerce published a preliminary affirmative LTFV determination for certain fatty acids from Indonesia on September 22, 2026 (91 FR 60096), finding dumping margins of 23.04% for the Musim Mas single entity (P.T. Musim Mas and PT Inti Benua Perkasatama; cash deposit 22.96% after subsidy offset), 12.32% for PT Wilmar Nabati Indonesia (cash deposit 12.31%), and 19.55% for all others (cash deposit 19.49%).* Suspension of liquidation and cash deposits apply from the publication date for the examined companies.
- Critical circumstances were found in part: they do not exist for Musim Mas or PT Wilmar but do exist for all other Indonesian exporters/producers, so CBP will suspend liquidation and require cash deposits retroactively 90 days (from on or about June 24, 2026) for those “all others” entries.* This aligns with the companion CVD investigation’s earlier critical circumstances finding (in part).
- Respondents requested and Commerce granted postponement of the final AD determination (to 135 days after publication, around early February 2027) along with extension of provisional measures to six months; the companion CVD finals remain aligned.* Interested parties may comment on the prelim. The ITC previously found a reasonable indication of material injury in April 2026.
- Trade publications highlighted the cash deposit requirements taking effect (with retroactivity for some Indonesian entries) and noted concurrent CVD prelim rates of ~16.47–16.48% for Indonesian producers from July 2026.* Limited practitioner discussion appeared on X around the publication date, with one regulatory account flagging potential price pressure on palm-derived oleochemicals.
Frequently Asked Questions
When Did the Indonesia Fatty Acids Cash Deposit Requirements Begin?
For Musim Mas and PT Wilmar Nabati Indonesia, suspension of liquidation and preliminary cash deposits generally apply to covered entries made on or after September 22, 2026. For all other exporters and producers, the preliminary critical-circumstances finding may extend those measures to entries made up to 90 days earlier.
Why Are the Cash Deposit Rates Lower Than the Dumping Margins?
The cash deposit rates reflect export-subsidy offsets connected to the companion CVD proceeding. Musim Mas has a 23.04% dumping margin and a 22.96% cash deposit rate; PT Wilmar has a 12.32% margin and a 12.31% deposit rate; all others have a 19.55% margin and a 19.49% deposit rate.
Does an HTS Number Confirm That a Fatty Acid Is Subject to the Case?
No. HTS classifications are useful for screening and identifying potentially affected entries, but the written scope controls. Importers should evaluate the product’s chain length, iodine value, degree of split, origin, and other relevant physical characteristics before making a scope decision.
Can an Importer Use an Examined Producer’s Rate When Another Company Exports the Goods?
Not automatically. Rate eligibility generally depends on the producer-exporter combination and the active customs instructions. Importers should validate both entities, confirm the transaction chain, and retain documentation showing why a company-specific rate applies. Unsupported assumptions can lead to rate corrections, additional deposits, or enforcement exposure.
Are Preliminary AD Cash Deposits the Final Duty Liability?
No. A preliminary cash deposit is security for estimated liability. The investigation’s final determination may establish different rates, and the amount ultimately assessed can also depend on later liquidation instructions or administrative reviews. Importers should track deposited amounts by entry and avoid treating the preliminary rate as a fixed final cost.
Do the Indonesian Rates Apply to Fatty Acids From Malaysia?
No. The Indonesian and Malaysian proceedings must be maintained separately. A product associated with the Malaysian companion investigation requires its own scope review, company mapping, rates, effective dates, and case records. Indonesian rates should never be copied into Malaysian supplier profiles merely because the products appear commercially similar.
