As toy inventors, toy manufacturers and buyers for stores that sell toys met for an annual trade show in New York last weekend, a topic besides which items were destined for holiday wish lists permeated the displays. President Donald Trump had announced he planned to further increase his tariff on Chinese imports. Would he? By Tuesday, Toy Fair attendees had their answer, and the talk about how it would affect the prices of playthings grew more urgent. The Toy Association notes that nearly 80% of the toys sold in the U.S. are sourced from China. The trade association's president says retail prices are expected to go up 15% to 20% by the back-to-school shopping season.
