Fireworks of all kinds — including sparklers, firecrackers, bottle rockets and Roman candles — are considered hazardous materials and are banned from all air and ground transportation through USPS because they pose a threat to safety.
“Shipping fireworks through the mail puts our employees, customers and transportation networks at serious risk,” said Acting Postmaster General and CEO Doug Tulino. “Even small items like firecrackers or bottle rockets can cause fires, explosions or injuries if mishandled.”
To keep employees and facilities safe, the Postal Service uses a range of tools, including technology and inspection protocols, to detect non-mailable items.
Persons caught mailing fireworks may face civil penalties, criminal charges, and other consequences.
Last year, the Postal Inspection Service opened 1,700 investigations into customer attempts to send hazardous materials through the mail, including fireworks and other explosives.
To help ensure a safe and celebratory holiday, the Postal Service encourages you to review the list of hazardous and restricted items before shipping any package.
You can find a full list in Publication 52 – Hazardous, Restricted, and Perishable Mail.
