NEW YORK — At the biggest toy industry trade show in the Western Hemisphere this past weekend, toy makers, as usual, displayed seemingly endless rows of stuffed animals, action figures and puzzles, hoping to entice retailers to pick their products.

But this year, the chatter at Toy Fair New York was dominated not by the next Barbie, but a larger game, one of global tactics, that could make most toys more expensive for U.S. consumers.

Almost 80% of toys sold in the United States are made in China. Last week, just as toy vendors from across the United States and dozens of other countries started to flock to the Javits Convention Center for the annual toy fair, President Donald Trump announced a 10% tariff on Chinese goods that would come on top of the 10% he already imposed a month ago.

On Tuesday, the tariff went to effect.

Companies big and small — from family- owned brands to household names — are trying to figure out how to manage the new costs related to tariffs. Stationed at a booth lined with plush stuffed animals, Linda Colson, vice president of sales at Mary Meyer Corp., said her company, based in Vermont, was in a state of paralysis over pricing. “We don’t know what to do,” she said. “I think a lot of people in this building are just waiting to see what everybody else is doing.”

Jay Foreman, CEO of Basic Fun, a toy manufacturer and distributor in Florida, sells to retailers like Walmart and Target. After Trump ordered the 10% tariff on China in February, Foreman started thinking of ways to avoid passing those costs to his customers. So on Feb. 26, he met with his company’s board to devise a plan that would split the burden: The company, its factories in China and its retail customers would each absorb 3.5% of the added cost.

But just hours later, Foreman tuned into CNBC and heard Trump declare that new tariffs on China could jump to a total of 20% this week. The company’s plans “went right out the window,” said Foreman, whose company employs about 110 people in the United States and 165 people globally.

“Now, those can’t be absorbed, and that additional tariff has to be passed on to the consumer,” Foreman added. “It tipped the domino.”

The Tonka Mighty Dump Truck, which Basic Fun licenses from Hasbro, retails for $29.99. That price will likely go up $5 to $10 for consumers, he said.

Some bigger companies at the show expressed confidence their Chinese suppliers would absorb some of the added costs, as factories would not want to lose business.

Three billion toys are sold in the United States each year, generating $42 billion in sales and supporting nearly 700,000 jobs, according to the Toy Association, a trade group representing the U.S. toy industry.

The association has been lobbying for an exemption from Trump’s broad tariffs, pointing in part to the fact that small businesses make up roughly 96% of the industry, said group CEO Greg Ahearn. During Trump’s first term, he had imposed 10% to 25% tariffs on many Chinese products — but he backed down from tariffs on toys, among other consumer goods.

Some toy manufacturing has moved to Mexico in recent years, but the 25% tariff Trump imposed on Mexico and Canada also went into effect Tuesday. On Thursday, tariffs on both were delayed until April.
