The move marks something of a break for the Koch network, which spent much of previous year lending critical outside help to the White House-led drive for business-focused tax cuts.
It wasn't immediately clear how such an arrangement would work.
The dispute with Mexico over tariffs makes it more hard to conclude talks on renegotiating NAFTA between the three countries, discussions that began previous year because Trump said the deal needed to be reworked to better serve the United States. Changes would have to be agreed by all sides.
But both USA neighbors are opposed to that possibility and Mexican President Enrique Peña Nieto and Canadian Prime Minister Justin Trudeau reaffirmed their commitment to reaching a new trilateral deal in a telephone conversation last week.
The Trump administration claims that these tariff increases are justified under Section 232 of the Trade Expansion Act of 1962, which permits an exception to trade rules to protect national security and are recognized under World Trade Organization rules.
Mexico's retaliatory list, published in the government's official gazette, included a 20 percent tariff on US pork legs and shoulders, apples and potatoes and 20 to 25 percent duties on types of cheeses and bourbon.

The Diplomat wrote, "with the start date looming for US tariffs on Chinese goods, the latest round of US-China trade discussions - possibly the last before tariffs take effect - ended without a breakthrough".
Cranberries made the list, as did US apples, with a 20% duty. Analysts - along with the Trump administration - have linked the US-China trade relationship with Beijing's cooperation in applying pressure on the Kim regime and achieving denuclearization. China has vowed to retaliate on everything from US soybeans to airplanes, and Beijing has said it will abandon its commitments if the USA follows through on its tariff threat. "Ongoing negotiations are a good sign and are certainly better than a tariff war".
In a statement released early Monday, the White House said the talks focused on reducing the United States' trade deficit by selling more agricultural and energy products to China.
Ross has called that system "a joke" (a dubious judgment considering the overall success the United States has had in it since its creation).
The 78-year-old NY resident is suffering from deteriorating health, according to a letter that older brother Charles Koch sent to company officials Tuesday morning.
Trump said last month that he was working with Chinese President Xi Jinping to give ZTE "a way to get back into business, fast". He is not going to withdraw from NAFTA.
