It is illegal to purchase fireworks in another state and transport them into Massachusetts. Do not purchase fireworks by mail. Government cannot prohibit the advertising and sale of fireworks by mail, but police do confiscate illegal shipments of fireworks. Many consumers attempting to circumvent the law have lost both their money and fireworks.
