For people aiming to "buy American" for Independence Day this year, it might prove difficult to obtain U.S.-manufactured fireworks.

As Statista's Niall McCarthy notes, most of the bottle rockets, roman candles and other fireworks on sale across the country trace their origin to China. Last year, China accounted for 90 percent of total U.S. fireworks imports, amounting to approximately $325 million, according to website World City.

Given that there are almost 14,000 fireworks displays every 4th of July, the fireworks industry is big business.

Revenue from consumer fireworks has exploded, increasing by 232 percent over the past two decades. Over that same time, revenue from display fireworks has increased by 155 percent as well. While a fun time for many and a growing consumer industry, over 15,000 people visited the hospital due to fireworks in July alone between 2006 and 2010, according to a recent study published by the Journal of Surgical Research.

Interestingly, one man drives fireworks trade across the Pacific and his name is Ding Yan Zhong, a Chinese businessman. Also known as "Mr. Ding", his companies account for about 70 percent of the pyrotechnics entering the U.S. and on average, 72 of his containers enter the country every single day.

Even though China accounts for the bulk of the fireworks trade by far, the U.S. does rely on several other countries for imports. Israel comes second in terms of import value with nearly $10 million, a miniscule amount compared to China.
