Dairy Feed Fat Duties Could Stack Toward 45%, Trade Lawyer Warns

Feed already consumes more than 40% of a dairy farm's total costs, and National Milk Producers Federation President and CEO Gregg Doud is warning the Commerce Department that new duties on C16 palmitic acid fatty acids would come straight out of farmers' margins.

Doud made the case in a letter to Commerce Secretary Howard Lutnick. Palm fats high in palmitic acid are a standard component in lactating cow rations across the U.S., he wrote, and no domestic substitute exists.

"[Palm fats high in palmitic acid] allow farmers to raise butterfat content without sacrificing milk volume, directly supporting the milk components that farmers are paid on," Doud said in the letter, obtained by Agri-Pulse. "Unlike many businesses, dairy farmers cannot pass rising costs along. Added input costs therefore come straight out of already narrow margins."

What does the math look like at the farm level?

Kevin Swager, part owner of Pacific Elements, a custom feed mix company, laid out the agronomics in plain figures. Feeding roughly half a pound of palmitic acid per day can lift a cow's milk fat from 3.5% to 3.7–3.8% on 100 pounds of daily production.

"Feed enough, and it raises the milk fat the way the cow digests it," Swager told Agri-Pulse. His company belongs to the Coalition for Affordable Ingredients, which represents manufacturers and farmers opposed to the antidumping and countervailing duty petition.

Replacing palmitic acid with tallow or other fats does not work, Doud argued: matching the content "would require feeding them at levels that suppress feed intake and milk production."

How did the case get here?

Vantage Specialty Chemicals Inc. of Deerfield, Illinois, filed the petition on Jan. 28. Vantage did not respond to a request for comment. The case targets fatty acid exporters in Indonesia and Malaysia alleged to sell below fair value.

In July, the International Trade Administration set preliminary rates: a 16% countervailing duty and roughly 23% antidumping rate on PT Musim Mas, one of the world's largest palm oil companies, based in Indonesia. Malaysian firms Evvap Sabun Malaysia Sdn Bhd and Palm-Oleo Sdn. Bhd. face a CVD near 4% and AD rates of about 4–7%.

Those duties could stack on existing levies. Indonesian and Malaysian products already carry a 10% Section 301 tariff over forced-labor enforcement failures — levies that replaced President Donald Trump's global tariffs struck down by the Supreme Court.

"These are preliminary numbers, and so they can go up or they could go down, right? And so, if you just add those up, you're getting up near 45% or something like that, already for some of the companies," said John Gurley, senior partner at ArentFox Schiff, who represents importer ICOF America Inc., a Musim Mas subsidiary.

Why isn't palm oil itself taxed the same way?

The executive order exempts palm oil and crude palm oil, but not their derivatives. Suzi Emmerling, founder of Calina Strategies LLC, speaking for the coalition, noted that high-purity lauric, myristic, palmitic and stearic acids already face Section 301 tariffs — and all four appear in Vantage's petition. The order's exemption annex omits palmitic acid's Harmonized Tariff Schedule number.

Swager said the earlier 10% levies "caused a whole lot of heartburn" and heavy losses before Pacific Elements built them into pricing. "This back-and-forth and potential this and that and up and down — it really doesn't work, and the product is going to virtually go away as it stands now," he said.

Can C16 win an exemption?

DOC held a scope hearing on Oct. 2 on whether to exclude fatty acids above 50% palmitic acid by weight, along with C12, C14 and C18:1. Gurley expects a determination this week, though Commerce did not confirm that timing.

Exemptions are rare. In his trade-relief career, Gurley has seen perhaps ten. An ITC staff report found most producers and importers see few meaningful product differences between sources — yet also stated that palmitic acids used in dairy feed "do not appear to be fungible with any other products and are not produced in the United States."

The supply constraint is climatic. Indonesia, on the equator, accounted for 57.3% of global palm oil production in USDA's 2025/2026 marketing year, with Malaysia second at 24.8%; the U.S. is not among the top ten producers.

NMPF met with DOC staff in early October, said Shawna Morris, the group's executive vice president of trade policy. The Orthodox Union and the Household and Commercial Products Association also wrote to Lutnick urging exemptions.

Commerce "tends to give the petitioner the benefit of the doubt," Gurley said, but overwhelming evidence and unusual consumer pushback prompted the department to hold a hearing at all. He calls himself "cautiously optimistic" — while conceding, "you should never guess too much about what the Department of Commerce is going to do."

The final determination lands around Feb. 5, 2027.
