However, the companies cited a study in their letter to the White House that found 25% tariffs on an additional $300 billion worth of Chinese goods would add more than $2,000 in costs for the average American family of four.
The cost to consumers wouldn't always go up by 25% if tariffs are imposed. Some retailers may decide to absorb some of the cost of the tariff, negotiate with the exporting company for a lower price or move production out of China.
But the Trade Partnership, a consulting firm that works with industry trade associations, estimated that prices on clothes in the United States would rise by 5%, even if apparel companies tried to shift production away from China.
"The ability of US retailers to shift sourcing from China to other suppliers is limited and could take years to complete," the Trade Partnership said in the report. "Even after possible changes in sourcing, the proposed tariffs would have a substantial negative impact on American consumers."
Prices for shoes would rise by 8% for consumers, while toy prices would increase by 16%. China is the biggest supplier to the United States for both items.
Nike (NKE), Adidas (ADDDF) and Under Armour (UA) previously warned in May that 25% tariffs on imported shoes from China would be "catastrophic" consumers.
The study also estimated that household appliance prices would rise by 3% for consumers and travel goods would go up by around 10%.
New tariffs would hurt Trump's voter base, said David French, a senior vice president at the National Retail Federation, which helped spearhead the letter.
"The president's base is among the most economically vulnerable in the country," he said. "These are exactly the people who cannot afford to pay hundreds or thousands of dollars more for everyday goods."
