Fireworks were introduced to the united states by immigrants

In the nineteenth century, many American manufacturers were branches of European companies. The earliest known manufacturer of fireworks for pleasure in the U.S.A. was the Du Pont family near Wilmington,Delaware in 1809. the business thrived until the 1940s and continued to supply powder for the industry until the 1970s.

China is usually considered the birthplace of black powder and firework making. Hundreds of factories supplied material for fireworks display celebrating religious festivals and public events, marriages and funerals.
Recent political changes in china have meant that many manufacturers are now allowed to invest private capital and trade unhindered across the world. Certainly, china leads the world in the volume of production and export. A large number of small companies,especially in Guangdong, Guangxi, Hunan,Jiangxi and Hebe provinces, feed the large exporters and display companies, which operate under such group titles as temple of heaven of Beijing or red lantern,and brand names like sunny, Vulcan and an ping.
A large percentage of the fireworks produced in Japan used to be exported, but this is no longer the case;the bulk of them are used internally. This is because they require so much expensive hand labor that the finished products are very costly.
