The U.S. is arguably never more dependent on China than on July 4, when the nation celebrates its rebellion against British rule with fireworks that are inevitably imported from China.

The U.S. gets almost all of its fireworks from China, and the industry is warning that tariffs on Chinese imports could limit supply and send prices soaring.

Some fireworks companies warn tariffs could slow business ahead of America's 250th birthday in 2026. The American Pyrotechnics Association warned of a shortage among new products.
