In the United States, consumer fireworks laws can vary widely from state to state, or even from county to county. It is not uncommon for consumers to cross a state or county line in order to purchase certain types of fireworks which are outlawed where they live. Furthermore, it is common for certain densely populated areas to have restrictions on the time of year which fireworks can be purchased, sold, or used, and have specific selling periods in place. These factors are all influenced by consumer fireworks regulations set forth by the United States government.
The Consumer Product Safety Commission defines what fireworks may be considered consumer fireworks. Below, we have listed the specifications, guidelines, and general consumer fireworks regulations set forth by the US government’s Code of Federal Regulations and the APA Standard 87-1 of the American Pyrotechnics Association. Please remember that these are general consumer fireworks regulations, and you should always check with your local and state gevernments to find out what the official consumer fireworks regulations are in your area.
