GCC for fireworks (16 CFR Parts 1500 and 1507)

Consumer fireworks must meet the CPSC fireworks requirements in 16 CFR Parts 1500 and 1507 — banned hazardous mixtures, powder limits per device type, fuse burn times, and base stability — and be certified by the importer with a General Certificate of Conformity. Fireworks are one of the most detained product categories at US ports: documentation and testing must be ready before shipment.

What the rules cover

Banned substances and mixtures, including sensitive compositions.
Powder and pyrotechnic composition limits per device type.
Fuse burn-time windows, base stability, and/or blast limits, plus mandatory warning text and placement.

Certification and enforcement

The importer certifies each device type with a GCC citing the applicable parts, supported by testing. Customs and the CPSC sample shipments routinely — oversized powder charges, short fuses, and unstable bases are the detention drivers, so pre-shipment testing against the exact device types is essential.

Questions people ask

Who can test fireworks?

Testing for certification is performed against the CPSC test methods — most sellers use laboratories that maintain the fixture requirements. Confirm the lab’s fireworks scope before shipping.

Do sparklers and novelties count?

Sparklers, fountains, and novelties fall within the consumer fireworks definitions with their own limits. Classify every device type in the shipment.
